[gentoo-user] gcc but no cc

[gentoo-user] gcc but no cc

[-- Attachment #1: Type: text/plain, Size: 803 bytes --]

The install for gcc 4.8.2 flaked out a bit (libgcc_s.so.1 went missing,
during the file installation phase, and therefore bash invocations failed
with missing library errors and i later found that libstdc++.so.6 was also
missing). I have since extracted those files from gcc-4.8.2.tbz2 (because
FEATURES="buildsyspkg"), and gcc-config has run cleanly, but i now notice i
dont have cc. Is it a link/symlink? If so what's the details?

Also given this is the second time i've had a gcc installation killing
libraries, I quite like the idea of having a static bash. Since there's no
"static" use flag, i'm thinking package.env will have
app-shells/bash static.conf

and env/static.conf will be;
CFLAGS="${CFLAGS} -static"

Is there a significant downside to that approach for a machine with plenty
of RAM?

It's an identical file to gcc, but not a hard link:

alanm@khamul ~ $ ls -al /usr/bin/cc
-rwxr-xr-x 1 root root 10424 Nov 16 00:43 /usr/bin/cc

alanm@khamul ~ $ ls -al /usr/bin/gcc
-rwxr-xr-x 1 root root 10424 Nov 16 00:43 /usr/bin/gcc

alanm@khamul ~ $ diff /usr/bin/cc /usr/bin/gcc

alanm@khamul ~ $ ls -ali /usr/bin/cc
531047 -rwxr-xr-x 1 root root 10424 Nov 16 00:43 /usr/bin/cc

alanm@khamul ~ $ ls -ali /usr/bin/gcc
530815 -rwxr-xr-x 1 root root 10424 Nov 16 00:43 /usr/bin/gcc

Thanks Alan.

adam@proxy ~ $ which cc
which: no cc in
(/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/opt/bin:/usr/x86_64-pc-linux-gnu/gcc-bin/4.8.2:/usr/lib64/subversion/bin:/usr/games/bin:/opt/vmware/bin)
adam@proxy ~ $ ls -l /usr/bin/cc
-rw-r--r-- 1 root root 10352 Nov 14 18:41 /usr/bin/cc

So, chmod +x to fix.

gcc was getting found in /usr/x86_64-pc-linux-gnu/gcc-bin/4.8.2/gcc
adam@proxy ~ $ ls -l /usr/x86_64-pc-linux-gnu/gcc-bin/4.8.2/gcc
lrwxrwxrwx 1 root root 23 Nov 14 18:41
/usr/x86_64-pc-linux-gnu/gcc-bin/4.8.2/gcc -> x86_64-pc-linux-gnu-gcc*
adam@proxy ~ $ ls -l
/usr/x86_64-pc-linux-gnu/gcc-bin/4.8.2/x86_64-pc-linux-gnu-gcc
-rwxr-xr-x 1 root root 767584 Nov 14 18:41
/usr/x86_64-pc-linux-gnu/gcc-bin/4.8.2/x86_64-pc-linux-gnu-gcc*
adam@proxy ~ $ ls -l /usr/bin/gcc
-rwxr-xr-x 1 root root 10352 Nov 14 18:41 /usr/bin/gcc*

so i chmoded that too so the /usr/bin one is found.

FWIW bash wont build statically, but will build with -static-libgcc
-static-libstdc++

Sounds like the package built correctly but bailed out in the install
phase before the chmod and mv
