installed gcc with java language enabled.. but no gcj !

im using gentoo...

i rirst had "-java" in my use flags while compiling gentoo.... but now i need java support in my compiler... (i need to compile java programs to native code)

so i have this commmand to re-compile gcc

USE="java" emerge gcc

gcc was re-compiled... but no gcj program !

i tried adding java to my default USE flags in /etc/make.conf

same result !

this is SOOO ANNOYING !

does anyone know whats gone wrong ?

im going to have to install gcc manually and keep 2 gcc installations on my system !

Theres a gcj use flag:

Code:

[ebuild   R   ] sys-devel/gcc-3.4.2-r2  -bootstrap -boundschecking -build -debug +f77 +gcj +gtk -hardened -multilib -n32 -n64 +nls -objc -static (-uclibc) 0 kB

But for me even enabling this doesn't give me gcj! Did you ever resolve this?

I saw the use Flag too ! but enabling it didnt help.

ive still not found a solution to this problem. maybe its a bug in the ebuilds for GCC ?
and the problem is it takes a whole GCC re-compile (takes ages on my machine) to find out if the latesst emerge --sync fixes it.

seems no-1 uses gcj ?
ive given up and started using sun's JDK javac byte code compiler.

I have it working, this is what you have to do:

First set the use flag, then do emerge -uDa --newuse world, to remerge gcc (plus anything else that is out of date).

Then do env-update && . /etc/profile. This adds the new gcj executable to the path.

You may also need to play with gcc-config to select the correct version of gcc as active.

Thanks to some guy on irc for helping me get it working!

Mark.
