Installation error,

[meatball]

Hi All, 

Error encountered when I was trying to install Salvus in my Mac Pro. I follow the steps in https://salvus.io/installation/#installation-on-osx, everything was just fine until the last step, when I used make -j.  seems like it has a difficult time of locating petsc.h. Can anyone help me with this, or should I just copy the file to every directory the error appears? Thank you so  much.

Hello,

It just looks like the PETSc library was not properly installed to the PETSC_DIR passed to Salvus. This sometimes is because the PETSc install process did not complete correctly. In the installation instructions you linked to, there is a comment prior to PETSc installation which says:

# Production/performance installation. Follow the on-screen instructions # after the configure step until the installation completes.

Basically, after the configure stage of PETSc, some instructions will pop up on the command line which direct you to complete the installation and quickly test whether it works. Can you re-run the PETSc installation and ensure that all these steps complete correctly? If they did, and if you used the recommend /opt/petsc as the prefix, in your /opt/petsc directory you should see a directory include/ with those missing header files inside.

Let us know if this helps!

Mike.
