When building (e.g., make.sh), there will be several errors displayed when the OS is unable to copy some of the subversion directories. These can be ignored.

Note on windows that the slashes are incorrect; yes, they are always trying to be 'different' ;) --- the correct line should be:

cd \path\to\arduino\build\windows

Here is a problem one might encounter when running under Ubuntu:

ERROR MESSAGE: java.io.IOException: Cannot run program "avr-gcc": java.io.IOException: error=2, No such file or directory

SOLUTION: sudo apt-get install gcc-avr avr-libc (see https://developer.berlios.de/bugs/?func=detailbug&bug_id=14728&group_id=3590)

(Ubuntu Linux 64) With the default file permissions you get from svn, you may encounter errors like these:

cp: cannot create regular file `work/hardware/tools/.svn/format': Permission denied

Just run the build as sudo, or do chmods as appropriate.

I've run into a couple of problems with the installation on Ubuntu Ibex on 64 bits.

First, I needed to install two additional packages: sudo apt-get install ia32-libs librxtx-java

Then, I had to select the Sun java implementation: sudo update-alternatives --config java

Then, after calling sudo make.sh, I set myself as the owner of all the files (sudo chown -R me`).

Finally, I removed the serial library and replaced it with the library provided by librxtx: cp /usr/lib/librxtxSerial.so work/lib/

HTH

I may have hosed up a step somewhere trying to build under XP, but I had to manually unzip jre.zip to a java directory into \arduino\build\windows\work. This may have been caused by trying to do a make before I included zip and unzip in cygwin.

@safetycap the slashes for windows are not incorrect. You are running under Cygwin and Cygwin uses the standard unix slash.

Using windows 7 I had serious issues with the Arduino interface under 0017, where a top left section of the IDE would get repeated side-by-side and in several rows. It made the IDE useless to say the least.

Compiling under Windows 7 (32-bit)cygwin. worked fine, following the guide above, with these comments;

Used the setup.exe from cygwin.com to install cygwin basics. Could not find out how to install seperate needed packages, so ran setup.exe again and clicked on "All - default", so it became "All - install" and all the packages of the complete cygwin was downloaded (several hundred mega bytes - as warned on the cygwin web site - actually cygwin grew from abt. 500Mb HD space to now useing 4.8Gb HD space) so this took a couple of hours, and had to be restarted a couple of times. But now its ALL available!

The svn download worked just fine. Compiled just fine. Had to: chmod +x run.sh to make it run, but now the Arduino IDE looks like it does when I run 0017 under a Linux boot. And I have to start Arduino from the cygwin command window, sort of just like I have to under Linux. So far so good.

I needed Teensy-0017 to integrate with 0018, wich it wouldn't. But by copying the JAVA folder from 0018 to 0017, the IDE interface seems to have been mended, and I still have Teensy installers available in 0017. Here is me hoping it will work stable now!?

I have a suggestion for the next arduino's IDE version. Just to change "code.getPrettyName()" (in the line 364 of EditorHeader?.java file) by "code.getFileName()" to have an access to files with same name but differents extensions.

@Per.Alvin, Same here w/ Vista

Im getting building errors from, launch4j:

It seems to go to "document and settings", why? there is nothing there to find cygwin is installed @ c:\cygwin java sdk @ programfiles and ant aswell

@rjwiersma, I had the same problem, identically, it turned out that running the ant command from within a cygwin screen was the problem. On XP, from the start menu, press Run... , enter cmd then press enter, now your in a DOS type screen, navigate to the build directory and simply type ant and enter.

When I try "ant run" I get the following error. The arduino file is there, I can run it as ./arduino if I cd to the linux/work directory first.

BUILD FAILED /root/development/arduino/arduino-read-only/build/build.xml:33: The following error occurred while executing this line: /root/development/arduino/arduino-read-only/build/build.xml:318: Execute failed: java.io.IOException: Cannot run program "linux/work/arduino" (in directory "/root/development/arduino/arduino-read-only/build/linux/work"): java.io.IOException: error=2, No such file or directory

@david.fowler same problem although i've installed avr-gcc and avr-libc. Any solutions so far?

Same problem here as david.fowler, I am running Slackware64 13.1. There is an arduino executable created in the linux/work directory but it gives errors when executed. There isn't a 64bit version on the download page for the latest version and this could be why. I have yet to get the arduino software working on a 64bit linux OS after a year of trying.

Hi, the linux 64 bit problem is due to a 32 bit version of librxtxserial.so. I downloaded http://rxtx.qbang.org/pub/rxtx/rxtx-2.2pre2-bins.zip and copied the librxtxserial.so and RXTXcomm.jar to the arduino/build/linux/work/lib folder. The IDE now loads though it does warn about an RXTX version mismatch. I haven't actually tried connecting an arduino yet though.

similar/same problem to david.fowler, schnee72, vmburd

Ubuntu 10.04 32bit svn rev: 1096 my arduino executable loads fine from ~/Repos/arduino/build/linux/work running `ant' in ~/Repos/arduino/build/ is successful but `ant run' in ~/Repos/arduino/build/ returns an error:

Cannot run program "linux/work/arduino" (in directory "~/Repos/arduino/build/linux/work"): java.io.IOException: error=2, No such file or directory

Having the same problem as bluesquall. Steps to reproduce: mkdir arduino git clone git://github.com/arduino/Arduino.git arduino cd arduino/build ant ant run

Currently investigating but no obvious solutions. I note that "linux/work/arduino" does in fact exist relative to the CWD; running it manually yields the following: Exception in thread "main" java.lang.NoClassDefFoundError?: processing/app/Base Caused by: java.lang.ClassNotFoundException?: processing.app.Base

Problem appears to be that the "processing" library is not built or is not on classpath.

Im getting this strange error: "Buildfile: build.xml does not exist! Build failed" But, in the build map build.xml is absolutely there, what could cause this error?

Got it to work, instead of just using "$ ant" i had to use "$ ant -buildfile build/build.xml"

When I build and run with ant the Arduino splashscreen shows up but after that the program quits without any message. I tried 'arduino.exe --l4j-debug' which creates a launch4j.log file. This is what I get. Any suggestions? I also already deleted the preferences.txt in the AppData? folder. I'm running on Win7 x64.

If you want to make the IDE upload in x86_64 land, there are a few modifications that you need to make.

1. Replace 32 bit avrdude with a 64 bit copy. If you're lucky it supports the type arduino
2. Modify the avrdude.conf definition for stk500v1 programmer to look like this:

programmer
  id    = "stk500v1";
  desc  = "Atmel STK500 Version 1.x firmware";
  type  = arduino;
;

In the 'Updating to the Latest Version' section of this tutorial it is mentioned that we should run 'git update'. Is this correct? I don't think update is a command that git recognizes.

Makes fine, runtime error:

This solve my linux 64 bit problem for 0022 version:

$ cd Downloads
$ wget http://rxtx.qbang.org/pub/rxtx/rxtx-2.2pre2-bins.zip
$ unzip rxtx-2.2pre2-bins.zip
$ wget http://arduino.googlecode.com/files/arduino-0022-src.tar.gz
$ tar xvfz arduino-0022-src.tar.gz

$ cd arduino-0022/build/
$ ant
$ ant dist
$ cd linux
$ ls -la arduino-0022.tgz (install as usual)

I have the same problem with the same errors as minirobo

on 64bit Ubuntu 10.04 (2.6.32-27-generic #49-Ubuntu SMP Thu Dec 2 00:51:09 UTC 2010 x86_64 ): - clone Arduino from git - run "sudo apt-get install sun-java6-jdk gcc-avr avr-libc " - run "sudo update-alternatives --config java" - cd Arduino - run "ant -buildfile build/build.xml" - downloaded rxtx-2.2pre2-bins.zip (see comment above) and exchanged the librxtxSerial.so - run "ant -buildfile build/build.xml linux-run"

thanks to the parent posters

ant -buildfile build/build.xml linux-run

im with minirobo and holycow .. the ELF class is causing issues ..

currently it looks like something in the build process is over-writing the pasted in librxtxSerial.so

Can someone help me with the JRE stuff. I am not a Java expert, when they say "Download and install a Java JDK and point the JAVA_HOME environment variable to its root directory. An error message that reads "Unable to locate tools.jar. Expected to find it in C:\Program Files\Java\jre6\lib\tools.jar" means you need to set JAVA_HOME to your JDK (not JRE) installation." What do they mean by point it to it's root directory? to the JRE6 directory under java or to the java root directory? Set PATH and JAVA_HOME env's but still getting the error....

I am running on window vista.

Ha! Went to Oracle and found a JDK, I didn't know what it was and it's a bit confusing as they call it a Java SE. It created a directory c:\Program Files\java\jdk1.6.0_21 and then I did the following and it seems to have worked.

set %JAVA_HOME=c:\Program Files\Java\jdk1.6.0_21\ set PATH=%PATH%;%JAVA_HOME%

and it worked as stated....sorry for the dumb question!

when compiling from repository (fetched yesterday), got error : BUILD FAILED /home/frans/apps/Arduino-IDE/Arduino/build/build.xml:34: The following error occurred while executing this line: /home/frans/apps/Arduino-IDE/Arduino/build/build.xml:146: Fix revision number in Base.java I'm using openSuse 11.3(64), installed java-1.6.0-sun jdk, ant (1.7.1-12.1) and apache-ant-regexp (1.7.1-12.2); and changed the 3 JAVA var's to the java-sun folders. Re-enabling the echo lines for the revision variables in build.xml on the revision-check showed this output :

echo? revision is 0022. echo? base revision is echo? .

I tried building in windows and cygwin today, with most recent pull. Everything builds fine, except when I try to run the exe, I get the initial splash screen, and then it disappears...nothing else loads. is there a log that gets generated?

Request for the experts - can you extend the text search, so it searches all open files ? The Ardupilot and Arducopter projects have many files, and searching each one manually is a pain. Thanks.

For ubuntu 10.10 do: sudo apt-get install openjdk-6-jdk openjdk-6-jre openjdk-6-dbg

I've just cloned and built with no problems reported by Ant, but am having the same trouble that Rick had on October 15, 2010.

Just build latest(10/23/2011) and had the problem where I only get splash screen. I did the following in the build dir...

"ant" "ant run" To fix this issue I did:

"ant dist" "ant run" and it seemed to fix the issue. Hope it helps those that follow the setup instructions and run into this issue....

The only warning I get is:

I had the same problem as jmr13 above. His solution works, but I also found a different solution: On a Windows 7 platform I found that after a successful build, the new Arduino v1.0 splash screen would appear then disappear. No error or reasoning. To fix this I figured out that I needed to decompress the jre.zip file. It contains a ‘java’ folder. Copy/paste this java folder into the \build\windows\work\ directory.

Did anyone have this problem: Trying to run Arduino IDE on PandaBoard? running Linux version 2.6.38-1208-omap4. I get this build error: <pre> ut@pandaboard:~/arduino/Arduino/build$ ant Buildfile: /home/ut/arduino/Arduino/build/build.xml

This might sound crazy, but I'd like to be able to create and compile and download sketches from an Android tablet...Samsung Galaxy Tab or Asus Tranformer.

Has anybody thought about what that might take?

Unable to locate tools.jar. Expected to find it in /usr/lib/jvm/java-6-openjdk/lib/tools.jar how can i solve this problem?

see above - An error message that reads "Unable to locate tools.jar. Expected to find it in C:\Program Files\Java\jre6\lib\tools.jar" means you need to set JAVA_HOME to your JDK (not JRE) installation.

I had to use the cmd for grabbing GIT: git clone https://github.com/arduino/Arduino.git

Please remind Windows users that CASE is important. Also, above command must be done while in cygwin\bin directory

What to do with this error?

The registry refers to a nonexistent Java Development Kit installation or the runtime is corrupted. The system cannot find the path specified.

The JAVA_HOME environment variable is set to "c:\Program Files\Java\jdk1.7.0_02" where the bin, etc. is.

Another Failure Mode (initial installation -Linux):

Followed all the suggestions in this thread. When trying to "verify" BareMinimum?, I get (from Arduino 1.0, tar rollout, git from 20120109, git from 20120119):

The "missing" file is not missing at all.

What I am missing is any clue where one adjusts the gcc command line, to add the -Isome/path. Any suggestions?

It also appears that the java compiled program wants to run against the source/build tree, a somewhat unusual and risky proposition, IMHO.

I am dead in the water... :-(

Three notes:

On the message posted by myself; It went away when I substituted Atmel's Linux toolchain for the

one built from a script on one of these esteemed forums. I apologize for forgetting the details but most people would guess correctly what I mean. It is the script that installs the whole set of development tools (gcc, ar, ld, etc.). It builds the gcc 4.5.1 cross compiler and it appears something is missing in the build.

(now traditional) Linux 'make install'. To ask users, many of are new to programing, to figure out which part of the entire Java source/build directory needs to be torn off is almost as presumptuous as leaving it in the source tree.

All this excitement is with Linux on an AMD64 motherboard, Mega 2560 I bought few weeks ago. The Mega is a TinyOS clone which appears identical to the real thing. I do not think this is a '!!!' problem, but what the Mega is doing relates to the problem. The Blink sketch seems immune (works flawlessly, but other sketches fail more).

Thanks for any comment.

Sincerely,

Sheem-On

I understood this was to be a first robot. I assumed the code would be available for download, as I haven't gone halfway through the beginner course! Now I'm bombarded with Cygwin, ant, mirrors, all this stuff I've never heard of. I finally found the text editor, but now what? Write my own sketch? This will take a while, guys! I sure was hoping to develop my interest bit faster....

"I understood this was to be a first robot. I assumed the code would be available for download,....."

Perhaps you should read the instructions on the main website here: http://arduino.cc/en/Guide/HomePage

I'm quite sure it will help. If you are new to programming there really isn't any reason to even be reading this page or this code repository.

como se usa con apple, compre una arduino uno para armar un robot pero no se como usarla. hay ejemplos hechos para mac. quisiera que el robot responda a comando funcionales, tengo para imprimir circuitos pero no encuentro el adecuaado para que funcione con un ipad. que me aconsejan

For some of us, there is a need for print functions (sprintf, printf etc.) to support floats. This necessitates a rebuild of the IDE. Follow the build instructions up to Step 3 (Build).

Find and open the file: /app/app/src/processing/app/debug/Compiler.java

Find the line: "-Wl, --gc-sections"+optRelax,

Replace the line with: "-Wl,-u,vfscanf,-lscanf_flt,-u,vfprintf,-lprintf_flt,--gc-sections"+optRelax,

Save the file and continue with the build process.

No build for arm. I tried adding the two lines to define the arm platform at the top of the build.xml, but eventually, it tries to load an Intel 32 bit .so file and fails. Will there be arm support (i.e. Raspberry Pi) in the near future?

GUD

I am trying to compile it under windows 7 x64. I run "ant" and "ant run" (On cmd) Ant doesn't run on my cygwin install. It creates work file with all inside except java folder. So when I try to run arduino, show the welcome window and close it... I have to do a modification in java code so I need to re compile it for me....

How can I solve this issue?

For those with the splash screen and then Arduino closing after "ant run" both Nathan of Sparkfun and jmr13 have working solutions.

"I had the same problem as jmr13 above. His solution works, but I also found a different solution: On a Windows 7 platform I found that after a successful build, the new Arduino v1.0 splash screen would appear then disappear.

For those that are adding in Leonardo type boards you will need to make adjustments to AvrdudeUploader?.java as well as an FYI
