[gentoo-user] Help, please! I've hosed my gcc.

[gentoo-user] Help, please! I've hosed my gcc.

[Alan Mackenzie]

Hi, Gentoo.

My gcc now fails to work.

I upgraded it earlier on (I think) after doing an emerge --sync.  I
can't remember the before/after versions, or even whether I've got both
of them.

lipgmp has a lot to do with my problem.  After my last emerge -uND
world, I think libgmp was upgraded.  At any rate the messages on the
screen directed me to

    revdep-rebuild --library /usr/libt64/libgmp.so.3

, which I did.  They then informed me I could safely delete libgmp.so.3,
which I also did.  :-(

Now, when I attempt gcc on the command line, I get the error:

    /usr/libexec/gcc/x86_64-pc-linux-gnu/4.4.5/cc1: error while loading
    shared libraries: libgmp.so.3: cannot open shared object file: No
    such file or directory

.  So, is there an easy way for me to recover a working gcc, or do I
have to do something desperate, like reinstalling Gentoo?  :-(

Help will be most appreciated.

Do you have a backup?

gcc-config -l

symlink it to the later version, or copy the lib over from another
system.

Then rebuild dev-libs/gmp and dont delete the lib!

I got bitten by this but only on one system - the file is supplied by
the later ebuild so I dont know why it asks to delete it.  Was in the
middle of a major snafu when it bit so didnt bug report it - should
have.

Check to make sure a gcc is selected:

gcc-config -l

Sometimes if a old version is removed the link is sort of left dangling 
in the wind.

Ah - gcc-config.  I did gcc-config -l, and it displayed 2 versions of
gcc.  Then I did gcc-config --help.  Then I did

    gcc-config x86_64-pc-linux-gnu-4.5.3

, and now gcc is working again, or more precisely the new one is working.
:-)  Thanks for the tip!
