I installed gcc version 3.4.4 yesterday as part of an emerge world. The emerge failed near the end and at that point gcc no longer worked. So I emerged the preious verions 3.4.3-r1 but it still is not working right. I can run emerges but I can not run make from the command line when compiling c code (it works for c++). I get the following error message when I try to make c source code: cc -g -O4 -fomit-frame-pointer -Wall -c cmshull.c make: execvp: cc: Permission denied make: *** [cmshull.o] Error 127 I shoud add that if I run gcc from the command line (gcc mysource.c) it works. When I emerge gcc or run gcc-config I get this error: Your gcc has a bug with GCC_SPECS. * Please re-emerge gcc. * http://bugs.gentoo.org/show_bug.cgi?id=68395 When I look at the above bug report is says it shold not happen with gcc versions later than 3.4.2-r3. This is aparently not correct. How to I fix this? Re-emerging gcc does not work. I am working on some software and this is really getting in my way.

it's a false positive which happens because your compiler is screwed up what are the permissions of your /usr/bin/cc /usr/bin/gcc /usr/bin/c++ files and such ?
office src # ls -l /usr/bin/gcc -rw-r--r-- 1 root root 0 Aug 19 17:53 /usr/bin/gcc office src # ls -l /usr/bin/cc -rw-r--r-- 1 root root 0 Aug 19 17:53 /usr/bin/cc office src # ls -l /usr/bin/c++ -rw-r--r-- 1 root root 0 Aug 19 17:53 /usr/bin/c++
what does `ls -l /usr/lib/misc/gcc-config` show
# ls -l /usr/lib/misc/gcc-config ls: /usr/lib/misc/gcc-config: No such file or directory
remove /usr/bin/gcc and /usr/bin/cc and then try to run `emerge gcc-config`
When I ran emerge gcc-config it complained about the GCC_SPECS bug. So I ran a gcc-config -f x86_64-pc-linux-gnu-3.4.3 and that appeared to work. I have tested it and it now is working. So it appears that removing /usr/bin/gcc and /usr/bin/cc, emerging gcc-config and then running gcc-config fixed the problem. Good job and thanks for your help.
