I have extensive optimizations, but for this failure, I changed my CFLAGS to the following and only the following to assure that it was -fPIC -fstack-protector and -pie doing this: CFLAGS="-march=athlon-xp -Os -pipe -fomit-frame-pointer -fPIC -fstack-protector" LDFLAGS="-pie" gpm dies with the following error: gcc -I/var/tmp/portage/gpm-1.20.1/work/gpm-1.20.1/src -DHAVE_CONFIG_H -include headers/config.h -Wall -DSYSCONFDIR="\"/etc/gpm\"" -DSBINDIR="\"/usr/sbin\"" -march=athlon-xp -Os -pipe -fomit-frame-pointer -fstack-protector -fPIC -march=athlon-xp -Os -pipe -fomit-frame-pointer -fstack-protector -fPIC -c -o prog/mev.o prog/mev.c gcc -L/var/tmp/portage/gpm-1.20.1/work/gpm-1.20.1/src -pie -o prog/mev prog/mev.o lib/libgpm.so prog/mev.o(.text+0x47): In function `user_handler': : undefined reference to `Gpm_FitValuesM' prog/mev.o(.text+0x173): In function `emacs_handler': : undefined reference to `Gpm_FitValuesM' prog/mev.o(.text+0x6c3): In function `do_snapshot': : undefined reference to `Gpm_GetSnapshot' prog/mev.o(.text+0x745): In function `do_snapshot': : undefined reference to `Gpm_GetLibVersion' prog/mev.o(.text+0x75e): In function `do_snapshot': : undefined reference to `Gpm_GetServerVersion' prog/mev.o(.text+0x87f): In function `interact': : undefined reference to `Gpm_Close' prog/mev.o(.text+0x994): In function `interact': : undefined reference to `Gpm_Open' prog/mev.o(.text+0xa89): In function `main': : undefined reference to `Gpm_Open' prog/mev.o(.text+0xaaa): In function `main': : undefined reference to `gpm_report' prog/mev.o(.text+0xad8): In function `main': : undefined reference to `gpm_report' prog/mev.o(.text+0xaf5): In function `main': : undefined reference to `gpm_report' prog/mev.o(.text+0xbf5): In function `main': : undefined reference to `Gpm_GetEvent' collect2: ld returned 1 exit status make[1]: *** [prog/mev] Error 1 rm prog/mev.o make[1]: Leaving directory `/data/sysdirs/var/tmp/portage/gpm-1.20.1/work/gpm-1.20.1/src' make: *** [do-all] Error 1 !!!

[ebuild R ] sys-libs/gpm-1.20.1 -(selinux) 0 kB Try relaxing off the CFLAGS some and/or try with USE=hardened gcc-3.3.3-r2 I used 3.3.3-r2 and my gpm works like a charm. /usr/sbin/gpm: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), stripped
solar: I have extensive optimizations, but for this failure, I changed my CFLAGS to the following and only the following to assure that it was -fPIC -fstack-protector and -pie doing this: CFLAGS="-march=athlon-xp -Os -pipe -fomit-frame-pointer -fPIC -fstack-protector" LDFLAGS="-pie" I did relax the cflags to test. I'll try the new gcc.
Can this bug be closed now?
Yes, he confirmed to me that the problem was no longer present.
Sounds like this is FIXED then
