Compiling mir-glas and gsl together as a dependency results in error. #22

Closed prasunanand closed 7 years ago

prasunanand commented 7 years ago

I am working on a software for mixed-modelling. Currently, I have been using BLAS' gemm routine and would like to switch to mir-glas. However, gsl library doesn't go well with mir-glas.

Here is a sample program that can be used to reproduce the errors. gemm_example.

dub.json => link

If I remove, gsl from dependencies and libs in dub.json, the program compiles without any errors.

dub build --compiler=ldmd2 --parallel --force -v results in

The order of parameters is important to build the final executable. Changed

and it works.

-L-lmir-glas should be followed by -L-lmir-cpuid
