<p class="MsoNormal"><span lang="EN-US">I am using a code that utilizes some of the PETSC capabilities. After configuring and installing PETSC on a cluster, I have set my environment variables $PETSC_DIR and $PETSC_ARCH. The code using PETSC compiles using
GNUMakefile and so using instructions on the website and in Makefile.user I added the following lines to the make file:<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">This seems like a trivial problem, however I cannot seem to figure out what exactly went wrong. I’d expect this cannot be installation problem, and most likely the linking? I would really appreciate some direction on
this problem.<o:p></o:p></span></p>
