Question

我正在尝试构建一个使用PETSc的项目。为此，我从https://github.com/jedbrown/cmake-modules下载了cmake模块。当我尝试构建项目时，收到以下错误消息：

(...)

-- petsc_lib_dir /cygdrive/d/Git-Projects/build_libs/INSTALL/petsc-3.7.5/lib
-- Recognized PETSc install with single library for all packages
-- Performing Test MULTIPASS_TEST_1_petsc_works_minimal

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
PETSC_LIBRARY_SINGLE (ADVANCED)

我已经下载了openMPI（cygwin软件包）并使用以下方法构建了Petsc：

＆＃34; - 前缀=＆＃34; where_petsc_will_be_installed＆＃34; --with-clanguage = C --with-mpi --with-cc = mpicc --with-cxx = 0 --with-fc = 0 --download-f2cblaslapack --with-debugging = yes＆＃34;

并使用以下方式导出路径：

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

为什么我会收到这些错误以及如何解决这些错误？

Answer 1

为了在cygwin中使用带cmake的petsc，它必须使用“--with-shared-libraries = 0”构建，你必须使用静态库。

不能与cmake一起使用petsc
