Recompile binaries with the new support of GLPK 4.60

[blegat]

@tholden has added support for GLPK 4.60, Windows binaries have been updated but this still needs to be done for Mac and Linux.

• Recompile for Linux 64 bits : glpkcc.mexa64
• Recompile for Linux 32 bits : glpkcc.mexglx
• Recompile for Mac OS 64 bits : glpkcc.mexmaci64

The binary for linux 64 bits has been updated here: https://github.com/VinTz1/glpkmex.git

Maybe now the Readme should be updated

I would like to use glpkcc.mexw64 on matlab. But I need to use the optimization option of the glpk code. For example, when you change the right side equations with the function: glp_set_row_bnds(GLP, lin, GLP_FX, vl, 1.0e20). In this case, I will need to interface for glpk subfunctions. Can anybody help me, please?!

[blegat]

glpkmex only support one shot optimization so you cannot modify the constraints.
If you want to modify the constraint, I advise you to use the Julia wrapper.
For a simple to use interface, you can use GLPK through JuMP which supports constraint modification.

[silvanflavio]

ok! Thanks. I'll check these.

I was wondering about your answer. Is possible to program a function such the glpkcc.cpp, but with reoptimization option? And so create the mex file. Or, is the Matlab not support ? Whether not, why? Is it about the pointers?!

[blegat]

I am not an expert in mex file but I don't see any reason why this wouldn't be possible

I have a Windows MEX with the latest version - 4.65.
I compiled it against the static library so it is a stand alone MEX with no need for the DLL.

Anyone interested in it in this package?

[tholden]

Yes! Please share. Thanks!

[RoyiAvital]

How do you want me to share it?
Can I add a ZIP file here?

OK, it seems I can :-):
See https://github.com/RoyiAvital/GLPKMEX.

[tholden]

Thanks! Could you possibly share your build script too?

[RoyiAvital]

Hi,
I actually did it manually.

But you know what, I will create a MakeMex as a MATLAB Script and put it here.

[RoyiAvital]

In order to be agile and independent I created https://github.com/RoyiAvital/GLPKMEX.
The package doesn't require doing anything manually, it will download GLPK automatically, compile it and generate the independent MEX.

Currently works on Windows and Linux against GLPK 4.65.
I intend to add macOS support as well.

I hope it will be useful to others.
