[Bonmin] Setting up Bonmin 1.8.7 with CPLEX 12.9

Wed Jun 5 12:25:32 EDT 2019

Thanks for helping me out here! The reason for building in CYGWIN was that the process is layed out specifically for Bonmin here <https://projects.coin-or.org/Bonmin/wiki/CygwinInstall>  and that my expertise of compilation processes is very limited.

So I switched to Msys2 but got stuck a bit earlier in the process with the error message

checking build system type... Invalid configuration `x86_64-pc-msys': system `msys' not recognized

configure: error: /bin/sh ../config.sub x86_64-pc-msys failed

I found a similar error in this github issue <https://github.com/coin-or/COIN-OR-OptimizationSuite/issues/6>  but `pacman -Syuu` returns that everything is already up to date. I set the path variables "C:\msys64\usr\bin" and "C:\msys64\usr\local\bin" and ran through things described here <https://www.devdungeon.com/content/install-gcc-compiler-windows-msys2-cc> . 

Again, any help is greatly appreciated!

Cheers,

Christoph

Pierre, thanks for replying to this e-mail and reminding me about it. Christoph, I can certainly also help with getting you building. Is there a reason you really want to build in CYGWIN? These days, Msys2 and/or Windows Subsystem for Linux are much better options. We have not really kept up the CYGWIN support, since these better options exist and since it has some "eccentricities." 

If you really want to build with CYGWIN, then sending your config.log is a good first step. Are you building with the Microsoft compilers or with gcc? I suspect it may have something to do with specifying Windows paths rather than POSIX paths.

Cheers,

Ted

Dera Christoph, 

I don’t have a windows machine so I am really unsure how to do it.

Can you please send your config.log and the output of make so that I can see what is the error.

I have not done it in a long time but compiling from windows was always painful and very long. You might consider using a virtual machine in linux.

Best regards,

Pierre

Dear experts,

I am trying to set up Bonmin 1.8.7 with CPLEX as MILP-Solver under Windows 10 using Cygwin and could really use some help. The configure script runs through successfully but I get an error message when executing the build command:

make[1]:Leaving directory „/cygdrive/c/Programme/Bonmin-1.8.7/build/Cbc“

make: *** [Makefile:312: all-recursive] Error 1

I had previously installed Bonmin (1.8.6) without CPLEX and it worked fine so I assume that the problem has to do with CPLEX even though the error occurs after leaving the Cbc folder.

Below, I provide some details that seem relevant:

I installed an academic version of CPLEX 12.9, obtained the required third party code for Bonmin as described in the instructions and used the command

./configure --with-cplex-lib="C:\Programme\IBM\ILOG\CPLEX_Studio129\cplex\lib\x64_windows_vs2017\stat_mdd\cplex1290.

lib" \

--with-cplex-incdir="C:\Programme\IBM\ILOG\CPLEX_Studio129\cplex\include\ilcplex"

for the configuration. It exits with the message `Main configuration of Bonmin successful`, so at least it seems that this part worked. I was a bit confused when specifying the path to the CPLEX library, as I did not find a libcplex.a file. Instead, the CPLEX-documentation  states:

  lib\<compiler>\<libformat>:

                Library files that contain CPLEX (cplex1290.lib) and

                CPLEX extensions to the C++ version of Concert Technology (ilocplex.lib).

so I assumed that cplex1290.lib is the required file(?).

For <compiler> I had the options: <x64_windows_vs2015, x64_windows_vs2017> and for <libformat>: <stat_mda, stat_mdd> and I tried out all four variations.

Any help is greatly appreciated!

Kind regards

Christoph
