All,
<div><br>
</div>
<div>I think that there is a bug in your Makefile in the ./src/libf/</div>
<div>directory that manifests itself on the Cray X[T/E] series of </div>
<div>systems when you compile 'pnetcdf' with Cray compilers. I</div>
<div>see that this has come up several times, but is not fixed.</div>
<div><br>
</div>
<div>I proceeded through the configure and make stages of</div>
<div>the process on our Cray XE6 as follows with issue:</div>
<div><br>
</div>
<div>module load PrgEnv-cray</div>
<div><br>
</div>
<div>autoreconf</div>
<div><br>
</div>
<div>
<div>export CC=cc</div>
<div>export CXX=CC</div>
<div>export FC=ftn</div>
<div>export F90=ftn</div>
<div>export MPICC=cc</div>
<div>export MPICXX=CC</div>
<div>export MPIF77=ftn</div>
<div>export MPIF90=ftn</div>
</div>
<div><br>
</div>
<div>(remember on the Cray all compiler flavors (cray, pgi, pathscale, gnu)</div>
<div> use the above wrappers, for the cray compiler these automagically</div>
<div> load the MPI libraries)</div>
<div><br>
</div>
<div>nohup ./configure --prefix=/share/apps/pnetcdf/1.2.0 --enable-fortran CC=cc CXX=CC F77=ftn F90=ftn FC=ftn > CONFIG.out 2>&1 &</div>
<div><br>
</div>
<div>(this works fine)</div>
<div><br>
</div>
<div>nohup make > MAKE.out 2>&1 &</div>
<div><br>
</div>
<div>(as does this)</div>
<div><br>
</div>
<div>make install > INSTALL.out 2>&1 &</div>
<div><br>
</div>
<div>(this fails with ...)</div>
<div><br>
</div>
<div>/bin/rm -f pnetcdf.F90</div>
<div>echo "! This file is automatically generated at configure time. Do not edit." > pnetcdf.F90</div>
<div>echo "" >> pnetcdf.F90</div>
<div>echo "module pnetcdf" >> pnetcdf.F90</div>
<div>/bin/cat pnetcdf_inc ./pnetcdf_api.interface >> pnetcdf.F90</div>
<div>echo "end module pnetcdf" >> pnetcdf.F90</div>

<div><span class="Apple-style-span" style="font-size:small">Nothing I see in archives really addresses this problem. The trouble </span></div>
<div><span class="Apple-style-span" style="font-size:small">here is that the Cray compiler does not generate a 'pnetcdf.mod' file</span></div>
<div><span class="Apple-style-span" style="font-size:small">by default if only the '-c' option is used. To get a '.mod' file you must</span></div>
<div><span class="Apple-style-span" style="font-size:small">use 'ftn -c -em pnetcdf.F90'.</span></div>
<div><span class="Apple-style-span" style="font-size:small"><br>
</span></div>
<div><span class="Apple-style-span" style="font-size:small">I got around this problem my completing the compile manually and</span></div>
<div><span class="Apple-style-span" style="font-size:small">correctly with the ./src/libf/ directory and then rerunning the install</span></div>
<div><span class="Apple-style-span" style="font-size:small">which then finds the now generated 'pnetcdf.mod' file. </span></div>
<div><span class="Apple-style-span" style="font-size:small"><br>
</span></div>
<div><span class="Apple-style-span" style="font-size:small">If there is something that you can do to fix this in the download</span></div>
<div><span class="Apple-style-span" style="font-size:small">that would be nice. </span></div>
<div><span class="Apple-style-span" style="font-size:small"><br>
</span></div>
<div><span class="Apple-style-span" style="font-size:small">Excepting this minor glitch, the procedure above should work</span></div>
