libm.a, libc.a

libm.a, libc.a

[Sewell, Granville]

I'm trying to compile a program using GFortran (on SUSE Linux) so that it will run on systems that do not have GFortran installed, when I try
    gfortran -static program.f

I get that ld can't find -lm and -lc, apparently I need libc.a and libm.a (I have only the dynamic libraries libc.so and libm.so).   I was told that the usual distributions of GFortran do not includes these static libraries.   So
 1) where can I find them (I tried Googling several things, can't actually find downloadable libraries)
 2) is there another way to compile using gfortran to produce an execuable that will run anywhere?   Seems like this would be a common need, why would that not be possible using usual distributions of GFortran.  I had no trouble with the old g77 -static, apparently that did include libm.a and libc.a

Thanks,

Granville Sewell

You really should post questions like this to comp.lang.fortran since 
this is a list for developers of the compiler and is not a general user 
support list.  There may be SUSE users in the more general Google group, 
and this question isn't related to gfortran, but to the packaging system 
of a particular distribution of the operating system.  I personally do 
not know anything about SUSE but on Fedora the additional rpm required 
is glibc-static (the particular static libraries you need are C 
libraries, not Fortran libraries).

Static binaries are pretty common for Windows but in the Linux community 
it's more typical to share source than binaries, which is probably why 
glibc-static or equivalent isn't installed by default.  Ultimately it 
comes down to the choices made by the distributor of the OS.

FX already told you that this is not a gfortran issue.
You need to install libc.a and libm.a for your specific
operating system.  You need to contact someone involved
with SUSE linux.
