[Java-gnome-developer] java gnome vs. pkg-config

[Dalibor T. <ro...@ka...>]

Hi all,

due to Mark Wielaard calling out for people to test java-gnome with 
their VMs, I've decided to try out java-gnome from CVS with kaffe from 
CVS. Unfortunately, I didn't get very far, but I managed to spot some 
problems ;)

1) The README file refers the user to an INSTALL file. There is no 
INSTALL file in the java-gnome CVS top level directory. But there is one 
in common/INSTALL. I could submit a patch, if you need one ;)

2) There is no configure script, and it doesn't seem to be documented 
how to generate it. I've came up with the grand idea of running
genConfigure.in, genMakefile.in and autoreconf, but that should be 
documented in the INSTALL file ;) Again, I could submit a patch, if 
necessary.

3) Finally, my configure run breaks due to

bash-2.05a$ ./configure --with-kaffe 
--with-kaffe-prefix=/tmp/topic/current-jit3/
checking for gcc... gcc
checking for C compiler default output file name... a.out
checking whether the C compiler works... yes

Add /tmp/topic/current-jit3//bin to path and check again.

checking for kaffe... /tmp/topic/current-jit3//bin/kaffe
checking for jar... /tmp/topic/current-jit3//bin/jar
checking for main in -libs... no
checking for pkg-config... /usr/bin/pkg-config
checking for gtk+-2.0 >= 2.2... Package gtk+-2.0 was not found in the 
pkg-config search path.
Perhaps you should add the directory containing `gtk+-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gtk+-2.0' found

configure: error: Library requirements (gtk+-2.0 >= 2.2) not met; 
consider adjusting the PKG_CONFIG_PATH environment variable if your 
libraries are in a nonstandard prefix so pkg-config can find them.

I have no idea what `gtk+-2.0.pc' is or where I can find it. Any 
pointers or ideas where to search for the file?

4) The FAQ says that you're looking for someone who's been using kaffe 
to compile things to help out. Well, here I am ;)

I've discussed the build failures Mark had with him on IRC, and I think 
currently, the problem when using kaffe's java compiler is that it 
doesn't know about the -sourcepath option. A way to fix that would be to 
avoid using -sourcepath altogether, and simply cd into the directory. 
Another way would be to (LN_S) the source files into a build dir, and 
compile from there.

All that being said, I look forward to run java-gnome apps on kaffe, 
since I think gnome & java would mix well. All the best wishes for 
getting into the official GNOME binding set.

cheers,
