[Bug fortran/34957] New: duplicate libgcc_s.1.dylib warning on Mac OS X Leopard

[dojo at masterleep dot com]

Under Mac OS X Leopard using the prepackaged gfortran binaries from 12/31/2007,
any fortran program emits a duplicate dylib warning when linked.  This is with
the Leopard version of XCode (3.0).

$ cat test2.f
        program test2
        write (*,*) 'hello'
        end
$ gfortran test2.f 
ld: warning, duplicate dylib /usr/local/gfortran/lib/libgcc_s.1.dylib
$ a.out
 hello
$ gfortran --version

Where did you get "the prepackaged gfortran binaries"?

What architecture are you using? and what gives

ls -l /usr/local/gfortran/lib/libgcc_s*
ls -l /libgcc_s*

The group on the symbolic links seems odd - that's a different user account
that doesn't do coding.  I didn't make any manual changes to
/usr/local/gfortran.

on the gcc build on my macBook under Leopard and I don't see any ld warning
(probably harmless, the linker from Apple seems quite overzealous in some
cases).

If the warning really annoy you you may try the latest version from

This should have been fixed by 30572.

I don't use Leopard yet.

I was thinking to this one. This is why I asked to check there was some files
/libgcc_s*, just in case the package installed it.

I don't understand the problem: I am using Leopard and gcc works rather well
with it: probably less bugs than with 10.4 (cannot remember the cat!-).

I'm also seeing this on a fresh bootstrap of 4.4.0.

I also have gfortran 4.2 installed, and seem to recall the problem surfacing
here, so perhaps it is not related to 4.3 or 4.4, but something left over from
4.2:

gfortran-4.2 -v
Using built-in specs.
Target: i686-apple-darwin8
Configured with: /Builds/unix/gcc/gcc-4.2/configure --prefix=/usr/local
--mandir=/share/man --program-transform-name=/^[cg][^.-]*$/s/$/-4.2/
--build=i686-apple-darwin8 --host=i686-apple-darwin8
--target=i686-apple-darwin8 --enable-languages=fortran
Thread model: posix
gcc version 4.2.3

gfortran-4.4 -v
Using built-in specs.
Target: i386-apple-darwin9.6.0
Configured with: ../gcc-4.4.0/configure --program-suffix=-4.4
--enable-languages=c,c++,fortran
Thread model: posix
gcc version 4.4.0 (GCC) 


ls -l /usr/local/lib/libgcc_s* gives:

--- Comment #9 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> ---
This is an old bug, which I have never really understood but hasn't been
reported to me (I package and distribution Mac gfortran installers) in many
years. So I'm closing it, please reopen if you see it in a recent version of
GCC / OS X.
