WRFV22 g95 on Mac supporting programs

Previously, I reported that I had to use tcsh to run WRFV22. Turns out I can run in bash if I specifically set the stacksize and datasize as follows

ulimit -s 65536
ulimit -d unlimited

To go along with the configure.defaults additions for g95 on Mac PPC, here are the flags I used for NetCDF and MPICH to get everything working. Specific versions of these programs I used were 3.6.0-p1 for NetCDF and 1.2.5 for MPICH.

netcdf-3.6.0-p1

* I used tcsh for the compilation

setenv CC /usr/bin/gcc
setenv CPPFLAGS "-O -DNDEBUG -DpgiFortran"
setenv CFLAGS "-O"
setenv CXX /usr/bin/c++
setenv CXXFLAGS "-O"

setenv FC g95
setenv F77 g95
setenv F90 g95
setenv FFLAGS "-O3 -fno-second-underscore"
setenv FCFLAGS "-O3 -fno-second-underscore"
setenv F90FLAGS "-O3 -fno-second-underscore"

./configure
* I then edited "macros.make", adding:
FLIBS = -lSystemStubs
F90LIBS = -lSystemStubs

./make
./make test
[all tests were found to work]
make install


mpich-1.2.5

* I used tcsh for the compilation

setenv FC g95
setenv F90 g95
setenv RSHCOMMAND "/usr/bin/ssh"
setenv CC gcc
setenv CXX gcc
setenv LIBS "-lSystemStubs"
setenv FFLAGS "-fno-second-underscore"
setenv F90FLAGS "-fno-second-underscore"
setenv CFLAGS "-fno-common -DFORTRANUNDERSCORE"

./configure --with-device=ch_p4 --without-romio
./make

* On one Mac PPC machine, I had to add -lstdc++ to LIBS, but another failed to work if that was done

* Although mpich compiles fine, the example programs would not compile without manually adding the "-fno-second-underscore" flag. Example:


mpif77 -fno-second-underscore -c fpi.f
mpif77 -o fpi fpi.o
