A linear algebra library that provides a user-friendly interface to several BLAS and LAPACK routines.

linalg's Issues

Dependency Build Scripts

The dependency portion of the build scripts currently work, but are in need of being cleaned up and redundant actions removed.

QRUpdate

Investigate leveraging https://github.com/mpimd-csc/qrupdate-ng to keep instep with a maintained code body for QRUpdate.

linalg_test failing initially but passing with rerun; ferror.h is not placed correctly

Weird results with test: if ctest test is run, linalg_test fails. However when I rerun with ctest test --rerun-failed --output-on-failure, it passes. Tried twice, it is reproducible.

P. S. Also the build cannot find ferror.h in ferror-src/include, since relevant flag is not passed. I had to copy that header to ferror-build/include.

How to get gfortran or ifort to find the ferror.mod file?

I am using the CMake files to compile your repositories. I cloned ferror, created a folder called "build" in ferror, and ran Cmake inside the build folder successfully. I was then able to build ferror and install it.

Next, I attempted to do the same for linalg. Linalg, of course, depends on ferror. However, the compilation does not work for linalg. Cmake does find the ferror package, because I gave the path as a command line option to Cmake. But the gfortran and ifort compilers are unable to find the ferror.mod file or shared libraries. Could the Cmake file for linalg correctly provide the ferror include paths to the Fortran compiler, so that the compiler can link ferror into the linalg executables? How would this be implemented in Cmake?

Some of the debug output follows. When I run CMake, I do get the message:
-- FERROR library found.
When I enter
cmake --build .
with gfortran, I get the error:
/linalg/src/linalg_core.f90:17:8:

 use ferror, only : errors
    1

Fatal Error: Can't open module file ‘ferror.mod’ for reading at (1): No such file or directory
compilation terminated.

With ifort, I get the error:

Any idea what goes wrong here?

Has been building earlier. Maybe something changed with CMake update.

Flush out complex-valued C API routines

There are a series of complex-valued C API routines that need some work and testing.
