[Libmesh-users] PETSC_DIR problem

[Harry P. <har...@gm...>]

Libmesh Users,
I am having trouble with getting slepc to read my PETSC_DIR environment
variable.

I successfully installed PETSC and set the environment variable for
PETSC_DIR in my .bashrc file. When I try execute the following slepc
configure script this is what happens:

*hpearce@tcol:/islhome/hpearce/Libmesh_installation_starting_05_03_18/slepc-3.9.1$
sudo ./configureChecking environment... ERROR: PETSC_DIR enviroment
variable is not set*
I already double checked my .bashrc file, which is of relevance because I'm
using a bash shell. The configure code in SLEPC activates a configure.py
code. I used print commands to find the offending line of code in
configure.py, which read:
*petsc.InitDir(slepc.prefixdir)*

I know InitDir() is a property in python, but I couldn't find the
definition of slepc.prefixdir. I did notice a line of code related to
prefixdir which said:
* pkgconfig.write('prefix=%s\n' % prefixdir)*

I assume it means the directory just above the one with slepc. In that case
I don't see why it didn't work to set the environment variable in the slepc
directory or above it.

I looked through the previous libmesh-users emails for help but that did
not address the problem. I also looked at the stack exchange website, which
did not help:
https://stackoverflow.com/questions/42763517/configuring-the-software-slepc-issue-setting-environmental-variables
.

Any help would be appreciated (including telling me if it's inadvisable to
ask this question on libmesh-users, since it's technically a SLEPC
question).
