Cannot build the makefile in Ubuntu (help wanted)

[EveCharbie]

I an trying to compile SLICOT on Ubuntu.
I deleted all the windows makefile and changed the name of all unix files from makefile_Unix to makefile.
When I hit make, I get:

( cd src; make )
make[1]: Entering directory '/home/charbie/Documents/Programmation/SLICOT-Reference-main/src'
ifort /O2 /fp:source /4I8 -c AB01MD.f
make[1]: ifort: No such file or directory
make[1]: *** [makefile:139: AB01MD.o] Error 127
make[1]: Leaving directory '/home/charbie/Documents/Programmation/SLICOT-Reference-main/src'
make: *** [makefile:46: lib] Error 2

Could you help me please?

Could you try to compile just one routine (e.g., AB01MD.f) to see if the path is correctly set and the object file can be generated?

Thank you for your answer.
I am sorry, I should have closed this issue. I found SLYCOT (https://anaconda.org/conda-forge/slycot) on conda-forge and it works as a charm for python.

Yes, this is probably the best choice. For Julia, there are also ready to use libraries on many platforms compiled with various free compilers (see https://github.com/JuliaBinaryWrappers/SLICOT_jll.jl).

ifort must be called from a Windows Makefile.

One problem is that the include statement of the .inc file in src/makefile_Unix is wrong:

• It is include ../make.inc but it should be include ../make_Unix.inc

If the command make -f makefile_Unix MAKE="make -f makefile_Unix" is used, it is not necessary to delete or rename the makefiles.

Unfortunately, the makefile_Unix files contain other errors. See PR
#14.

Here, the command make -f makefile_Unix is sufficient.
The flags for Blas and Lapack still have to be set.

The debian pkg (https://salsa.debian.org/science-team/slicot/-/blob/master/debian/rules?ref_type=heads) could be useful, created by @svillemot.

I still have problems understanding the flags of make. At least I was able to compile something on Ubuntu22.04.

I would also like to see detailed installation instructions for Ubuntu/Debian.
