Re-Hello

I am trying to compile a java project split into at least 2 directories

obj.source_root = 'api/javadao/src api/javacommon/src'

but I got

2 source roots? you must be joking

Comment 2 by francelyme, Mar 28, 2009

no the project is split into a javacommon/src/fr... and javadao/src/fr...

Comment 3 by tnagy1024, Mar 28, 2009

Then there will be two different libraries

Comment 4 by francelyme, Mar 28, 2009

actually no, the project juste split the .java files in two directory and i must
compile all files in same time to generate only one .jar.
TangoORB.jar to be precise.

files under javadao are using classes described into javacommon and vis et versa ;)

Comment 5 by tnagy1024, Apr 17, 2009

Can you give the command-lines to do that?

The current example is for compiling all at once, for compiling file by file i guess
the include paths should be given.

An alternate possibility, if all the files are compiled at once, is to use a
make-like rule.

Yes you compile all the files at once.
I did not tried file by file. When I removed the gcjonce or something like that I
could not compile (indeed due to the include path).

so the source_root find recurcively all the files under each root directory and
compile them at once.

Comment 7 by tnagy1024, Apr 17, 2009

have you tried something like this:

src = bld.path.ant_glob('**/*.java')
bld.new_task_gen(source=src, target=foo, rule="gcj -o ${TGT} ${SRC}")

?

Comment 8 by francelyme, Apr 18, 2009

No but I will try
thanks :)
