Subject: Problem with libg2c
Dear Sir,
I have a problem with libg2c on a newly-installed Fedora Core 5 system.
When I compile programs that require libg2c, I have got this error.
/usr/bin/ld: cannot find -lg2c
collect2: ld returned 1 exit status
error: command 'c++' failed with exit status 1
However, when I check, I have found that it exists on the file system.
/usr/lib/gcc-lib/i386-redhat-linux/3.2.3/libg2c.so
/usr/lib/gcc-lib/i386-redhat-linux/3.2.3/libg2c.a
/usr/lib/libg2c.so.0.0.0
/usr/lib/libg2c.so.0
Does anyone know how to fix this problem? Thank you in advance for your
help.

You could try a symlink from those libraries into some place on the library search path of the compiler you are using
(for g++, try g++ -print-search-dirs), copy it to your current directory, or specify the full path of the library you want.

It's also possible you no longer need libg2c: it (IIRC) is for g77 the old
Fortran implementation that has been replaced by gfortran. (That said you
may need to link something else instead for gfortran but I don't know enough
about it.)
The one you found on disk:

is for the old compatibility compiler: Fedora Core 5's system compiler is
gcc 4.1 not 3.2.3. Or you could try building your program with that compiler
instead.
Rup.

I'm sure someone has attempted to post a reply, as I've done myself. I
guess you didn't try obvious possibilities, like replacing -lg2c with
the entire path of the library you desire, as you didn't say what errors
came about. If you cared, evidently g++ -print-search-dirs would show
you which directories are searched for libraries.
