At least all that I've used have it. Gcc, path64/open64/ekopath-bin,
solstudio use shared lib. Pgi by default links statically, but have
shared too. Ifort has only static, but has "ugliness" called Portability
Library, which can be linked dynamically:
xarth@aiur:~$ ifort -fpscomp nolibs unlink.F90 -lifport
xarth@aiur:~$ ldd a.out | grep ifport
libifport.so.5 =>
/opt/intel/Compiler/11.1/072/lib/intel64/libifport.so.5 (0x00007f0e05968000)
It *really* makes things easier if virtual/fortran is in RDEPEND. Is it
serious obstacle?
Cheers,
Kacper
