So yeah, I just finished upgrading to gcc3.2.2 (from 2.95.3) and things seem to be going ok so far, but I'm having some flag problems. I'm trying to do an emerge --deep -e world, but it always stops when trying to compile bash-2.05b-r3 with the complaint that | Code: | | checking for C compiler default output... configure: error: C compiler cannot create executables |
My CFLAGS are : | Code: | | CFLAGS="-march=athlon-xp -O2 -pipe -fomit-frame-pointer -fexpensive-optimizations -frerun-cse-after-loop -frerun-loop-opt -falign-functions=4" |
which I've been using for quite some time now on several systems with no problems. However, the config.log file at /var/tmp/portage/bash-2.05b-r3/work/bash-2.05b/ claims
| Code: | cc1: Invalid option `-falign-functions=4'
cc1: bad value (athlon-xp) for -march= switch |
If I remove both of those it works, so I change my cflags to this:
| Code: | | CFLAGS="-mcpu=k6 -O2 -pipe -fomit-frame-pointer -fexpensive-optimizations -frerun-cse-after-loop -frerun-loop-opt" |
and everything is fine. To save the obvious questions, my cpuinfo output is:
| Code: |
processor : 0
vendor_id : AuthenticAMD
cpu family : 6
model : 6
model name : AMD Athlon(tm) XP 1800+
stepping : 2
cpu MHz : 1533.719
cache size : 256 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 1
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse3
6 mmx fxsr sse syscall mmxext 3dnowext 3dnow
bogomips : 3014.65

so I'm not crazy here, I do have an Athlon XP, it just isn't clear to me why those two flags (march=athlon-xp and falign-functions) don't work. Help?

| Did you unmerge gcc-2.95.3 after upgrading? Check which version of gcc is 'active' by 'gcc --version' Also see gcc-config. |

I did not unmerge gcc-2.95.3 after upgrading (wasn't sure if that was a good idea or not). I did make sure that gcc 3.2.2 was in my path but I'm not sure if this qualifies as 'active'. I don't know much about gcc-config yet, but from what I gather I should have a profile indicating certain information about the version of gcc I want to use. I don't have any profiles, which I think could be the source of the problem but I'm not sure what to do about it.
