GCJ as Java SDK, dead, long live IcedTea!

azureus-2.5.0.4 requires gcj-jdk-4.3 as build jdk (jdk-1.5 is in DEPEND).
though, with gcj-jdk-4.3 there won't start any download.
running azureus-2.5.0.4 with gcj-jdk-4.2 requires this:
(and still gets oom-kills

Been getting this error when trying to emerge eclipse-ecj-3.3*

Any suggestions would be nice as without this i can't install >gcj-4.2*

woa, someone still using gcj-4.1.
mmh, you may use sun-jdk to compile eclipse-ecj.
I do not support gcj-4.1 anymore.
was too lazy to drop its ebuild yet.

anyone on amd64 arch with '-fvisibility-inlines-hidden' in their CXXFLAGS get gcj-4.3 compiled?
fails here with floating point number error; ICE in libgcc/directives.c:2076.

Same here! Does it compile without '-fvisibility-inlines-hidden'?
I don't have the time to test it right now, will try tomorrow or the day after.
BTW I never succeeded in compiling gcj-4.3 on amd64, always ran into this bug: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30136

From info I got from some gentoo devs, -fvisibility-inlines-hidden shouldn't be in your CXXFLAGS.

It'll be enabled automatically by the packages which actually support it.

So i got past the dreaded <DCASHMODE> error by taking out my -march CFLAG for the build (why this works i have no idea). Subsequently i bug out with this error: http://pastebin.ca/340830

I'm getting this error on compilation:

geki · Posted: Mon Feb 05, 2007 12:43 pm Post subject:

yes, one should not have -fvisibility-inlines-hidden in CXXFLAGS. though, system is still running here.

dolcraith looks bad ...

I will recompile gmp and mpfr without visibility enabled.
Other things I cannot imagine. And got no time for digging into that...

may be this causes the ICE...

update #1
recompiled gmp & mpfr without visibility enabled
gcc trunk fails like this now.

what I did. recompile gmp and mpfr without visibility stuff.
no idea if that does anything. I just saw c code.
other thing I do right now, testing gcc trunk.

that error disappeared, though, like I said another error appeared with -march=nocona I guess.
I have to test -march=x86_64 because amd64 arch does not seem to hit this new error.

ok, some more testing shows that it is unrelated to the split-wide-types feature.
I found a way to get around the segfault by replacing -march=nocona with -march=core2 (plus -mssse3) for the compiler stage buildflags.
so the c compiler is optimized to core2 and libgcc still with nocona.
should not hurt, though. yay!

Just in case someone wants to build gcc-4.3 on nocona and sees the segfault in gcc/libgcc.c, here is the code-snipped which should be in toolchain.eclass (alike), too:

hell, near to release eclipse-3.3M5, though some libs are not installed.
anyone, please tell me where libupdate.so and liblocalfile*.so are located in the installset.
of any version of eclipse, so that I can copy them manually.

mmh, using java startup instead of eclipse binary for now.
libupdate.so in eclipse root (?).
internal browser waits for 127.0.0.1 ... forever and a day.

M5 has some issues (on x86_64) that M4 (on x86) did not have.
so be warned... if you got a usable M4 you better not update!

Not sure about the error as I'm now getting different ones, but there are some problems with paths. gcj-4.3.0 installs into /usr/lib/gcj..., while gcj-jdk sets them as /opt/gcj... in /etc/env.d. Changed to match. Current error is

geki · Posted: Thu Feb 22, 2007 6:47 pm Post subject:

mmh, gcc-4.3 expects patched ecj that you try to build.
merge ecj with gcj-4.2 and then again with gcj-4.3.

I encountered strange errors like that when I had gcj-4.2 and gcj-4.3 installed.
that happened because gcj-4.3 compiled the Java source and gcj-4.2 built native code.

you may check if you have any java-config-1 leftovers, delete them.
