I have created an Anaconda Pytyoh 2.7 environment on an SGI-ICE<br>
machine and included cython, numpy=1.12, scipy, and mpi4py (based<br>
SGI-MPT). While petsc installs fine with:<br>

<br>
I cannot get petsc4py to build/install. I am attempting with:<br>
<br>
% export<br>
PETSC_DIR=${PREFIX}/envs/myenv<wbr>/lib/python2.7/site-packages/<wbr>petsc<br>
% pip install --no-dependencies petsc4py<br>
<br>
Note, I am using "--no-dependencies" because I want to leave numpy<br>
at 1.12 and do not want it to be upgraded. Either way I get the<br>
output below. It appears that the link command has been corrupted<br>
with the addition of the "gcc" command in the middle of the link<br>
command.<br>
<br>
<br>
/vendor/sgi/mpt/2.14r19/bin/mp<wbr>icc is being called. Does this actually work? I would suspect it of calling 'gcc'<br>
<br>

<br>
Matt, Thanks for the response.<br>
<br>
Yes, `/vendor/sgi/mpt/2.14r19/bin/m<wbr>picc` is a compiler wrapper that ultimately calls gcc. The problem is that in the middle of the link line there is an extraneous "...-fstack-protector -g -O gcc -pthread -shared -B...". From the error message, it is this embedded "gcc" that is the problem.<br>
<br>
I cannot see where petsc4py gets its compiler and linker commands. It would appear that they come from petsc.</blockquote><div><br></div><div>I would not have that interpretation. This is because the build outputs the Petsc information underneath PETSC_ARCH</div><div>and it shows the compiler and linker given to it. Neither has 'gcc' in it. You could grep the files in</div><div><br></div><div> $PETSC_DIR/$PETSC_ARCH/lib/petsc/conf</div><div><br></div><div>for 'gcc', but i suspect it will not be there.</div><div><br></div><div> Thanks,</div><div><br></div><div> Matt</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Again, it appears that the link line is being constructed inappropriately.<br>
