Compiling Magma on Windows

Post by pinnacleman98 » Wed Jul 01, 2020 2:37 pm

Hi, all:

I'm porting a large fortran code with many blas and lapack calls to GPU with OpenAcc and PGI compilers. I want to use magma to maximize the portability of the GPU code. I downloaded Magma 2.5.3. I'm using CMake to configure and generate a solution file for VS 2013. After some struggle, I managed to genereate the solution file. But when I tried to build, VS gives me lots of error of
Error 112 error MSB6006: "cmd.exe" exited with code 1. C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V120\Microsoft.CppCommon.targets 170 5 magma

I tried to compile the source file one by one in magma project manually and found the problem is happened when compiling all .cu files (all cuda kernel files). I don't know how to fix this error. Here is my system information

Configure output from CMake configure:

I'm using windows 10.

Any help and advice will be deeply appreciated.


BTW, It seems that the developer of the Magma didn't build the windows version before release as there is apparent error in CMakeLists.txt which causes cmake fail to configure.

We have had difficulty with CMake compiling MAGMA on Windows. This appears to be a bug or deficiency in CMake. It is unclear when this occurred -- whether some new version of CUDA, CMake, or MAGMA broke it -- as we have previously compiled MAGMA with CMake on Windows. See this thread:

It seems there are some incompatibilites from C++ of VS and Linux. I am reading some threads talking about similar issue, just googled this:

Code: Select all

cl.exe doesn't support the -std
But it seems more like a change on the codebase of the project than from your side.
