Update: Just before submitting this issue, i tried to run arduino by double-clicking the executable and choosing "run" under "/build/linux/work/arduino". So it builds perfectly and this bug report is only valid for the failure of "ant run" command.

I have Ubuntu lucid installed on my laptop. When i try to compile arduino from source and try to run, i get error. Here are the outputs.

for "ant"

bugra@bugra-laptop:~/ard/arduino/build$ ant Buildfile: build.xml

I have lastest version - rev 1088 as well as "gcc-avr", "avr-libc" "sun java 6 sdk u20" and "sun java 6 jdk u20", "ant 1.7.1", "make 3.81"

I have the same problem, so I just run the generated arduino script manually. If anyone has a fix, I'd love to apply it.

fixed it! Line 318 in build.xml should be,

I guess the problem was it couldn't find the executable 'arduino'

I applied your change, bugraokcu, but it didn't actually fix the problem for me, so I'm leaving this open. Anyone have any other ideas? Do we need to specify an absolute path somehow?

I'm using Apache Ant version 1.7.1 compiled on July 2 2010.
