[LLVMdev] Error trying to build llvm-gcc

[Prakash Prabhu]

Thanks for the quick reply, Edwin.

I tried with --enable-languages=java and it still fails with the same error:

../llvm-gcc/configure --enable-languages=java,c++,c --prefix=/usr/local
make ENABLE_OPTIMIZED=0

Actually I found that when I manually add /usr/share/java/libgcj-4.2.jar to
the classpath to the failed command, it seems to work:

/home/pprabhu/llvm/llvm-objects/gcc/gcj
-B/home/pprabhu/llvm/llvm-objects/gcc/ -B/usr/local/i686-pc-linux-gnu/bin/
-B/usr/local/i686-pc-linux-gnu/lib/ -isystem
/usr/local/i686-pc-linux-gnu/include -isystem
/usr/local/i686-pc-linux-gnu/sys-include --encoding=UTF-8 -Wno-deprecated -C
-g *--classpath=/usr/share/java/libgcj-4.2.jar* -bootclasspath
/home/pprabhu/llvm/llvm-objects/i686-pc-linux-gnu/libjava':'../../../llvm-gcc/libjava':'../../../llvm-gcc/libjava/external/w3c_dom':'../../../llvm-gcc/libjava/external/sax
-d /home/pprabhu/llvm/llvm-objects/i686-pc-linux-gnu/libjava
../../../llvm-gcc/libjava/java/lang/Class.java

But I am not sure if this is the right jar file that has to be passed (Is
SignerInfo available somewhere within the llvm-gcc source distribution that
I am failing to add to the configure script  ? ) More generally, how do I
pass some custom jar file to to the configure script, to be added to the
class path of gcj ?
