yes. You would run 'make check' after the build - to verify if PETSc examples are able to compile, link correctly [to this libpetsc.so] - and run And then - you should be able to use it similarly with your application code. If there are issues with building your application code - compare the compile command used for the petsc examples with the compile command used for your application code Note: configure option --with-shared-libraries=1 [default] builds petsc shared library - i.e libpetsc.so. And if you use --with-shared-libraries=0 - it will build petsc as static library - i.e libpetsc.a A compiler (linker) will look for shared library and use it if found. If not found - it will look for a static version of the library - and use it if found.
