Interested in Joining the Development Team
Oct 21st, 2006, 10:30pm  
Hi,

I'm a C/C++ programmer with experience in audio and 3D graphics on Windows. I'm interested in getting some experience working on a large scale java project.

I've downloaded the Processing source code however I haven't been able to get it to compile. I'm not using Cywin however I have all the other development tools installed.

When I do a build I'm getting the following errors:

$ make.sh
Building processing.core
c:/programming/processing/app/preproc/PdePreprocessor.java:302:5:302:12: Semanti                   c Error: Type "processing.app.preproc.PdeLexer" was not found.
c:/programming/processing/app/preproc/PdePreprocessor.java:302:27:302:34: Semant                   ic Error: Type "PdeLexer" was not found.                

etc...

Any idea what's going on here?

Also, how do you guys go about debugging if you're not using an IDE?

Cheers,

Chris

that'd be great if you can help.

the build scripts are designed to work with cygwin, that's why the instructions say to install it. if you're not using it, then the build is gonna break.

as for debugging, i watch for exceptions and use println as necessary. sometimes the core and libraries i'll debug with eclipse, but the environment itself i handle via command line.

OK, I guess I'll have to install Cygwin!

Regarding debugging, why not setup the whole project in Eclipse?

Cheers,

Chris

I've installed Cygwin however now I'm getting the following errors:

Chris@laptop /cygdrive/c/programming/processing/build/windows
$ ./make.sh
: command not found

: command not found
./make.sh: line 211: syntax error near unexpected token `else'

Any ideas?

hm, someone else ran into this as well.. let's figure out what's going on.

are there quotes in your QTJAVA environment variable?

No quotes anywhere that I can see.

QTJAVA is set to:

C:\Program Files\Java\jre1.5.0_06\lib\ext\QTJava.zip

I checked that it's there too.

Cheers,

Chris

It might be a problem with the presence of carriage returns in the make.sh file.  I had a similar problem with Arduino, so I opened make.sh in vi and did a find/replace to get rid of the carriage returns; type :s/<ctrl-v><ctrl-
m>//g (where <CTRL-V> means pressing control and v at the same time).  Then it worked.

sorry to lose track of this.. i'm looking at the file and don't see any CRs, though there are sometimes problems with the QTJAVA. as i'm trying to reproduce this, are you using QuickTime 6?
