See SL_LINKER_FUNCTION and SL_LINKER_SUFFIX, e.g., as used from gmakefile.

Isn't the Exodus build system capable of that?

That option goes into FC_FLAGS.

[petsc-dev] petsc makefiles

[Blaise A Bourdin]

Hi,

Is there a way in petsc makefiles to figure out how to link a shared / dynamic 
library
i.e. if I want to know how to do 
$CC -shared *.o lib.so
vs.
$CC -dynamiclib *.o lib.dylib
what variable gives me the extension .so vs .dylib and the linker option 
-shared vs -dynamiclib

How about doing the same thing in BuildSystem (I need to build a shared library 
for exodus)?

Also, is there a way to know the family of compiler I am using (gnu vs intel vs 
something else)?
The long line fortran compiler options for fortran and ifort are of course 
different, and the default behavior opposite…
