Help wanted to generate mex-files for Linux and Mac. #1

Open andreasvarga opened 3 years ago

andreasvarga commented 3 years ago

The mex-files for Windows have been generated by Vasile Sima, based on the latest developments of the SLICOT library. However, versions of mex-files for Linux and Mac are presently missing. I would highly appreciate any help in generating versions of mex-files for Linux and Mac. This is now possible, since the last version of SLICOT is available on GitHub under a BSD license. To allow the generation of mex-file, the source codes are also freely available (see the mexfiles directory.)

Hey Andreas,

I'm trying to generate the mex files on Ubuntu right now, but I'm having trouble compiling the Fortran files. I built all of the required libraries already, and I believe I've made proper makefiles to build the Fortran source for DSTools. When I run make, the following appears in the terminal while it's attempting to compile sl_glme.F:

( cd src; make -f makefile )
make[1]: Entering directory '[libs]/DescriptorSystemTools-main/mexfiles/src'
gfortran -O2 -fPIC -fdefault-integer-8 -I[matlabroot]/extern/include/ -c CHCKID.F
gfortran -O2 -fPIC -fdefault-integer-8 -I[matlabroot]/extern/include/ -c sl_glme.F
sl_glme.F:183:70:

  183 |       IF ( mxGetM( PRHS(1) ).NE.1 .OR. mxGetN( PRHS(1) ).NE.1 ) THEN
      |                                                                      1
Error: Cannot assign to a named constant at (1)

Unfortunately, I don't know Fortran, so I can't really understand why this error is occurring. Am I not linking the MATLAB header files correctly? Any help would be appreciated. I'd be happy to submit a PR containing the mex files for Linux and Mac if I can get this working.

EDIT 1: I just saw the .m included to generate the mex calls. Running those commands gives the same error unfortunately.

EDIT 2: Alright, nevermind. After some playing around, I got everything to compile properly, and everything seems to work. I had to use the -ffixed-line-length-none option to get it to compile. I'll submit a PR with the Linux and Mac mex files in the coming few weeks!

Thanks for your efforts. I look forward for completion of your work.
