[SCIP] Installing SCIP linking CPLEX 12.8 under Windows using MinGW

[Shin, Jungeun]

Hi,

I have been trying to install SCIP with Cplex 12.8 on Windows using MinGW and have some questions.



  1.  I don't quite understand the following part of the "Remarks on Installing under Windows using MinGW" from installation information of your website.


" Second you need to copy the file sh.exe to bash.exe otherwise various scripts (including makefiles) will not work. Normally unistd.h covers also the getopt-options, but for mingw you need to add the entry #include <getopt.h> into "/mingw/include/unistd.h" after the other include-entries (if not present). "

What does it mean by copying the file sh.exe to bash.exe? Does it mean to change the file name? Also, there is no unistd.h file in my ""/mingw/include/".

  1.  I proceeded to installation ignoring the part described in 1). Then, I encountered the following error, saying that my cplex directory is not a directory. Can this error related to bash.exe? or did I use wrong path?


C:\Program Files\scip-7.0.0>make ZLIB=false READLINE=false GMP=false LPS=cpx

* SCIP needs some softlinks to external programs, in particular, LP-solvers.
* Please insert the paths to the corresponding directories/libraries below.
* The links will be installed in the 'lib/include' and 'lib/static' directories.
* For more information and if you experience problems see the INSTALL file.

  -> "cpxinc" is the path to the CPLEX "include" directory, e.g., "<CPLEX-path>/include/ilcplex".
  -> "libcplex.*.a" is the path to the CPLEX library, e.g., "<CPLEX-path>/lib/x86-64_linux/static_pic/libcplex.a"
  -> "libcplex.*.so" is the path to the CPLEX library, e.g., "<CPLEX-path>/bin/x86-64_linux/libcplex1263.so"

  1.  From the mailing list archives, I found this.  http://listserv.zib.de/pipermail/scip/2017-February/002995.html
It says there was an interface change in Cplex 12.7 and recommend to use an older vertion of CPLEX.
Is this still an issue if I want to install Cplex 12.9 ?


Thank you all !
