[petsc-users] Build error with slepc: Unable to locate PETSc BAMG dynamic library

[Satish Balay]

Ah - so --have-petsc4py=1 disables this check in slepc? Ok - tried that - and it works for me.

[balay at pj01 petsc]$ ./configure --download-bamg --download-slepc --download-petsc4py --download-slepc-configure-arguments="--with-slepc4py=1 --have-petsc4py=1"
