Portland Group Fortran (pgf77) Compiler

Portland Group Fortran Compiler compiles the XBC option tree and other X-Midas host primitives written in Fortran (see X-Midas Backwards Compatibility (XBC) for details on X-Midas host primitives in NeXtMidas).

Some PGI Fortran Compiler installations are not setup properly causing errors when building XBC. For example:

       nM> make all xbc
       ...
       INFO: Compiling /opt/midas/nxm282/nxm/host/newrate.for [BUILDOPT]
       /usr/bin/ld: /crtbeginS.o: No such file: No such file or directory
       ...
The issue here is that the PGI compiler setup file at <PGI_INSTALL_DIR>/bin/localrc (e.g. /usr/pgi/linux86/5.2/bin/localrc) does not point at the gcc installation. The key info here is that the linker was not finding one of the "C" run-time object file (as it was trying to look for it in the root directory)

There are several ways to solve this problem:
  1. Try to run the <PGI_INSTALL_DIR>/bin/makelocalrc utility. e.g. /usr/pgi/linux86/5.2/bin/makelocalrc -x `pwd`
  2. Hand modify the <PGI_INSTALL_DIR>/bin/localrc setup file as follows (e.g. on a RHEL4 system):
    set LFC=-lg2c;
    set LDSO=/lib/ld-linux.so.2;
    set GCCDIR=/usr/lib/gcc/i386-redhat-linux/3.4.6/;
    set GCCINC=/usr/lib/gcc/i386-redhat-linux/3.4.6/include;
    set G77DIR=/usr/lib/gcc/i386-redhat-linux/3.4.6/;
    set LOCALRC=YES;
    set THROW=__THROW=;
  3. Add /usr/lib/gcc/i386-redhat-linux/3.4.6/ into /etc/ld.so.conf -or- to a new gcc3.4.6.conf file under /etc/ld.so.conf.d
