[AMBER-Developers] Problems with PGF90

Hi All,

I decided to try compiling AMBER Tools and AMBER with PGF90. Granted my
pgf90 is very old v6.1.2 but this is all I have access to.

I get:

pgf90 -c -O1 -Mfree -o add_pdb.o _add_pdb.f90
PGF90-S-0038-Symbol, command_argument_count, has not been explicitly
declared (_add_pdb.f90: 1)
  0 inform, 0 warnings, 1 severes, 0 fatal for add_pdb

It looks like command_argument_count is a F2003 intrinsic. Are we allowing
F2003 specifics in the code now or should this code be rewritten to be
F90/95 compliant?

As for building amber, this stops at:

PGF90-S-0000-Internal compiler error. size_ast_of: unexpected ast type
4 (_xray_utils.f: 497)
  0 inform, 0 warnings, 1 severes, 0 fatal for write_header
make[1]: *** [xray_utils.o] Error 2

Looking at the code this refers to:

       h_map_arch_stamp = transfer( CHAR(native_FT*16+native_FT) &
               // CHAR(native_IT*16+1) &
               // CHAR(0) // CHAR(0), &

= yuck! No idea what is going on here.

Does anyone have a more up to date PGF90 to test with?

All the best
