what version of the sun FORTRAN compiler does the

   "config_fc --fcompiler=sun"

switch expect. We have 

f90 -V
f90: Sun WorkShop 6 update 2 Fortran 95 6.2 Patch 111690-07 2002/06/26
Usage: f90 [ options ] files.  Use 'f90 -flags' for details

installed. It does not know the "-f77" switch.

It turns out, my problem is the "/bin/bash" wrapper around the f90
call. Why is exec_command.py running

   spawnvpe(0,'/bin/sh',['/bin/sh', '-c', 'f90', '-f77', '-ftrap=%none', '-xcode=pic32', '-c', 'lib/numfort/NB.F', '-o', 'build.Engmodel/temp.solaris-2.8-sun4u-2.2/lib/numfort/NB.o'],os.environ)

instead of 

   spawnvpe(0,'f90',['f90', '-f77', '-ftrap=%none', '-xcode=pic32', '-c', 'lib/numfort/NB.F', '-o', 'build.Engmodel/temp.solaris-2.8-sun4u-2.2/lib/numfort/NB.o'],os.environ)

? My problem can be shown with

hoel at donau:test /bin/sh -c "f90 -f77 -ftrap=%none -xcode=pic32 -c lib/engforcegen/cylforces.f -o build.Engmodel/temp.solaris-2.8-sun4u-2.2/lib/engforcegen/cylforces.o"
f90: Warning: Option -f77 passed to ld, if ld is invoked, ignored otherwise
ERROR: Cannot open source file "lib/engforcegen/cylforces.f".
hoel at donau:test /bin/sh -c f90 -f77 -ftrap=%none -xcode=pic32 -c lib/engforcegen/cylforces.f -o build.Engmodel/temp.solaris-2.8-sun4u-2.2/lib/engforcegen/cylforces.o
Usage: f90 [ options ] files.  Use 'f90 -flags' for details
hoel at donau:test echo $?
0

"-c" requires the command to be called as string intead of a
tuple/list of arguments.

I changed lines 348-351 to:

        if type(command) is type([]):
            argv = [sh,'-c', " ".join(command)]
        else:
            argv = [sh,'-c',command]

and it now seems to work for me.

Kind regards
