Unable to install with scip

[myisis]

I followed the instructions from the readme and when I run make (step 5), this error message occurs:

ffind: illegal option -- n
usage: find [-H | -L | -P] [-EXdsx] [-f path] path ... [expression]
       find [-H | -L | -P] [-EXdsx] -f path [path ...] [expression]
Makefile:47: /make/make.project: No such file or directory
find: illegal option -- n

       find [-H | -L | -P] [-EXdsx] -f path [path ...] [expression]

       find [-H | -L | -P] [-EXdsx] -f path [path ...] [expression]
make[1]: *** No rule to make target `/make/make.project'.  Stop.

I then remove line 47 include $(SCIPDIR)/make/make.project and get this error message.

make[1]: *** No rule to make target `python/SCIP.i', needed by `wrapper'.  Stop.
make: *** [scip_lib] Error 2

Is there anything else I need to do? I used the current master of NumberJack.

Hi, You need to set ZIBPATH to point to the folder containing the scipoptsuite source code.

We're currently working on the new build system, under the distutils branch (https://github.com/eomahony/Numberjack/tree/distutils). If you download this branch, you can simply place the scipoptsuite-3.1.0.tgz in the same folder as the extracted Numberjack code and run python setup.py build, followed by python setup.py install. Let us know if this resolves your issue.

I can't find the link to this branch any more, but if this is now Numberjack-1.1.0 the installation through pip runs fine without any errors. Is there anything else besides pip install numberjack to get it running with scip? I tried the warehouse example from your website and get this error message (ZIBPATH was set to /usr/local/scip-3.1.0):

Traceback (most recent call last):
  File "warehouse.py", line 62, in <module>
    solve_warehouse_planning(WareHouseData(), input({'solver':'SCIP'}))
  File "warehouse.py", line 35, in solve_warehouse_planning
    solver = model.load(param['solver'])
  File "/usr/local/lib/python2.7/site-packages/Numberjack/__init__.py", line 849, in load
    raise ImportError("ERROR: Failed during import, wrong module name? (%s)" % library)
ImportError: ERROR: Failed during import, wrong module name? (SCIP)

Hi @myisis, To help debug, can you send the complete output log of pip install numberjack and a directory listing of /usr/local/scip-3.1.0 to numberjack.support@gmail.com

Regards, Barry

$ ls /usr/local/scip-3.1.0

It looks like you are pointing ZIBPATH to the installed location of SCIP, it should point to the directory where you have extracted scipoptsuite-3.1.0.tgz The folder should contain scip-3.1.0.tgz, soplex-2.0.0.tgz, zimpl-3.3.2.tgz etc.

I've used brew to install SCIP. Does this not work?

No, you need to download the scipoptsuite tgz from http://scip.zib.de/#download
