I am on a pentium4 so I have set march=pentium4 in my cflags. I updated gtk+ (in combination with upgrading to gnome 2.8) und found my eclipse not to work any more (It just hangs as soon as I try changing anything in a .java file, eating up all CPU). From the forum I got the information to try remerging some stuff with march=pentium3 set. Done that and remerged gtk+ (gtk+-2.4.9-r1 to be exact) and everything works again. Don't know if this should be set in an ebuild or forewarded to the gtk or eclipse dev-team Reproducible: Always Steps to Reproduce: 1. use a pentium4 in your cflags 2. emerge gtk+ 3. emerge eclipse-sdk 4. run eclipse, open a java file (maybe try to edit it) Actual Results: Computer just hangs eating up all CPU Expected Results: Let me work :(
I can reproduce this bug too. When gtk+ is emerged with -mpentium4, Eclipse 3.0 just hangs. It works when I re-emerge with -mpentium3. I have attached part of strace while Eclipse splash screen is frozen (it keeps getting SIGSEGV over and over). I tested with Linux 2.6.7 and 2.6.9-rc2, GCC 3.4.2, and Sun JDK 1.4.2_05. $ strace -p15265 rt_sigreturn(0x4d7760f8) = 139637952 --- SIGSEGV (Segmentation fault) @ 0 (0) --- rt_sigreturn(0x4d7760f8) = 139637952 --- SIGSEGV (Segmentation fault) @ 0 (0) --- rt_sigreturn(0x4d7760f8) = 139637952 --- SIGSEGV (Segmentation fault) @ 0 (0) --- rt_sigreturn(0x4d7760f8) = 139637952 --- SIGSEGV (Segmentation fault) @ 0 (0) --- rt_sigreturn(0x4d7760f8) = 139637952 --- SIGSEGV (Segmentation fault) @ 0 (0) --- rt_sigreturn(0x4d7760f8) = 139637952 --- SIGSEGV (Segmentation fault) @ 0 (0) --- rt_sigreturn(0x4d7760f8) = 139637952 --- SIGSEGV (Segmentation fault) @ 0 (0) --- rt_sigreturn(0x4d7760f8) = 139637952 --- SIGSEGV (Segmentation fault) @ 0 (0) --- rt_sigreturn(0x4d7760f8) = 139637952 --- SIGSEGV (Segmentation fault) @ 0 (0) --- rt_sigreturn(0x4d7760f8) = 139637952 --- SIGSEGV (Segmentation fault) @ 0 (0) --- rt_sigreturn(0x4d7760f8) = 139637952 --- SIGSEGV (Segmentation fault) @ 0 (0) --- rt_sigreturn(0x4d7760f8) = 139637952 --- SIGSEGV (Segmentation fault) @ 0 (0) --- $ uname -a Linux raquel 2.6.7 #4 Thu Jul 22 18:45:39 Local time zone must be set--see zic manu i686 Intel(R) Celeron(R) CPU 2.80GHz GenuineIntel GNU/Linux $ gcc -v Reading specs from /usr/lib/gcc/i686-pc-linux-gnu/3.4.2/specs Configured with: /var/tmp/portage/gcc-3.4.2-r2/work/gcc-3.4.2/configure --enable-version-specific-runtime-libs --prefix=/usr --bindir=/usr/i686-pc-linux-gnu/gcc-bin/3.4 --includedir=/usr/lib/gcc/i686-pc-linux-gnu/3.4.2/include --datadir=/usr/share/gcc-data/i686-pc-linux-gnu/3.4 --mandir=/usr/share/gcc-data/i686-pc-linux-gnu/3.4/man --infodir=/usr/share/gcc-data/i686-pc-linux-gnu/3.4/info --with-gxx-include-dir=/usr/lib/gcc/i686-pc-linux-gnu/3.4.2/include/g++-v3 --host=i686-pc-linux-gnu --enable-nls --without-included-gettext --enable-__cxa_atexit --enable-clocale=gnu --enable-shared --with-system-zlib --disable-checking --disable-werror --disable-libunwind-exceptions --with-gnu-ld --enable-threads=posix --disable-multilib --disable-libgcj --enable-languages=c,c++ Thread model: posix gcc version 3.4.2 (Gentoo Linux 3.4.2-r2, ssp-3.4.1-1, pie-8.7.6.5) $ java -version java version "1.4.2_05" Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_05-b04) Java HotSpot(TM) Client VM (build 1.4.2_05-b04, mixed mode)
Same here! Maybe with gtk+-2.4.10 it will be fixed.
I reassigned to gnome@gentoo.org since I doubt it is a java error (Same bug for different Eclipse Versions and JDKs, and remerge of GTK fixes it)
thats all nice, but if you recompile with all different CFLAGS that would point at a gcc thing, not gnome. And since you are running a known problematic gcc, I'm not surprised things don't work. And noone here posted 'emerge info' like always should be done.

maybe the gcc porting team can have a look & make a statement on reliability on gcc-3.4.2 & pentium 4 ?

Can you have a look at this? It works nicely with 3.3

Btw. USE="-gtk motif" emerge eclipse-sdk worked fine for me with openMotif. But who wants this crappy, outdated look? ;o) Maybe we'll find out more about support gcc versions and CFLAGS on gnome.org?! Regards, Torsten
gcc-3.4.x was so kind as to break sse2 our gcc-3.4 ebuilds disable sse2 so this should be fine (if you rebuild things)
