Note that this macro was only put in just before petsc-3.3, so if you want to support versions older than 3.3, you'll need something like #if !defined(PETSC_VERSION_LT) # define PETSC_VERSION_LT(major,minor,subminor) ... #endif > call MatCreateMPIAIJ( comm, PETSC_DECIDE, PETSC_DECIDE, nnodes, > nnodes, & > maxn1, PETSC_NULL_INTEGER, maxn1/2, PETSC_NULL_INTEGER, & > AA, ierr ) > #else > call MatCreateAIJ( comm, PETSC_DECIDE, PETSC_DECIDE, nnodes, nnodes, & > maxn1, PETSC_NULL_INTEGER, maxn1/2, PETSC_NULL_INTEGER, & > AA, ierr ) > #endif > > > and I get errors like: > > /autofs/na1_home/adams/XGC1/XGC1_3/./module.F95:1189: undefined reference > to `matcreatempiaij_' > /autofs/na1_home/adams/XGC1/XGC1_3/./module.F95:1215: undefined reference > to `matcreatempiaij_' > /autofs/na1_home/adams/XGC1/XGC1_3/./module.F95:1235: undefined reference > to `matcreatempiaij_' > > > Am I not using this correctly? -------------- next part -------------- An HTML attachment was scrubbed...
