My i686 machines failed to build app-text/texlive-core-2007-r13 with the keywords 86, however, my amd64 successed building the package with keywords amd64. These to PC used the same USE flags.

what version of sys-apps/ed are you using ?
The sys-apps/ed was not installed.
Alexis Ballier, thank you for your reply. I installed the sys-apps/ed-0.9 and have tried to emerge texlive-core-2007-r13, but It failed again :-(
can you try to go in the /var/tmp/portage/app-text/texlive-core-2007-r13/work/texk/dvipsk and run the command: ed tex.lpro <<edscriptend /% begin code for uncompressed fonts only/d .,/% end code for uncompressed fonts only/d .,/% end of code for unpacking compressed fonts/s/% // w texc.lpro edscriptend and see if it works? If it segfaults I'll probably need a backtrace: http://www.gentoo.org/proj/en/qa/backtraces.xml
I went in /var/tmp/portage/app-text/texlive-core-2007-r13/work/texk/dvipsk and run the command: ed tex.lpro <<edscriptend /% begin code for uncompressed fonts only/d .,/% end code for uncompressed fonts only/d .,/% end of code for unpacking compressed fonts/s/% // w texc.lpro edscriptend and got the information: Segmentation fault I have read the article "how to get meaningful backtraces in gentoo": http://www.gentoo.org/proj/en/qa/backtraces.xml Because I am not good at programming,therefore I can understand it afond:-(. But I did a try: 1.CFLAGS="-march=pentium3 -O2 -ggdb" CXXFLAGS="${CFLAGS}" 2.$gdb emerge and got some error : "/usr/bin/emerge": not in executable format: File format not recognized Now, what I shall do next step, could you give me some details in the present situation? Thank you!
(In reply to comment #5) > 1.CFLAGS="-march=pentium3 -O2 -ggdb" CXXFLAGS="${CFLAGS}" > 2.$gdb emerge No, you need to install sys-apps/ed with these C{,XX}FLAGS and with FEATURES=nostrip or splitdebug and then run: gdb ed $ run tex.lpro <<edscriptend /% begin code for uncompressed fonts only/d .,/% end code for uncompressed fonts only/d .,/% end of code for unpacking compressed fonts/s/% // w texc.lpro edscriptend if you get a segmentation fault, gdb will catch it, and typing 'bt full' will give you the information needed.
Alexis Ballier , Thank you for your patient. I run the commands as your instruction. But there are some errors: This GDB was configured as "i686-pc-linux-gnu"... (no debugging symbols found) Using host libthread_db library "/lib/libthread_db.so.1". (gdb) run tex.lpro <<edscriptend The program being debugged has been started already. Start it from the beginning? (y or n) y Starting program: /bin/ed tex.lpro <<edscriptend (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) Program received signal SIGSEGV, Segmentation fault. 0x0804c183 in ?? () I don't know whether the relsusts are that you want or I did something wrong? Thank you again!

() > > I don't know whether the relsusts are that you want or I did something wrong? not really ;) You should have installed sys-apps/ed with debug information (like explained on the backtrace guide, dont strip it and build it with -ggdb) and then typed "bt" or "bt full" in gdb to get a backtrace.
Alexis Ballier, I built the sys-apps/ed with CFLAGS="-march=pentium3 -O2" and CXXFLAGS="${CFLAGS}", then the texlive-core emerged successfully. Thank you very much!
