为什么Magma 2.5不能编译？

Question

我正在尝试用NVIDIA GTX 960M在我的笔记本电脑上编译Magma 2.5，它总是提示链接问题。

我已经将cmake版本升级到最新版本(3.14.3)。下面是错误输出的一部分。

lib/libmagma_sparse.a(magma_sparse_generated_magma_dsampleselect.cu.o): In function `magma_dsampleselect':

Answer 1

尝试将以下文件添加到CMake.src文件中的libsparse_all目标：

sparse/blas/magma_dsampleselect_core.cu
sparse/blas/magma_sampleselect.cu
sparse/blas/magma_ssampleselect_core.cu

由于重新编译速度慢，我还没有验证这个解决方案。
