Cannot use petsc with cmake


I was trying to build a project that uses PETSc. To do so, I downloaded the cmake modules from https://github.com/jedbrown/cmake-modules . When I tried to build the project, I got the following error messages:

(...)

-- petsc_lib_dir /cygdrive/d/Git-Projects/build_libs/INSTALL/petsc-3.7.5/lib
-- Recognized PETSc install with single library for all packages

I've downloaded openMPI (cygwin packages) and built Petsc using:

"--prefix="where_petsc_will_be_installed" --with-clanguage=C --with-mpi --with-cc=mpicc --with-cxx=0 --with-fc=0 --download-f2cblaslapack --with-debugging=yes"

and the paths were exported using:

export PETSC_DIR="where_petsc_is_installed"
export PETSC_ARCH=""
export PATH=${PATH}:${PETSC_DIR}/lib:${PETSC_DIR}/bin

Why did I get these errors and how to solve them?


Solution

  • In order to use petsc with cmake in cygwin, it must be built using "--with-shared-libraries=0", you must use static libs.
