Installing JSCIPOpt referencing debian package SCIPOptSuite-5.0.1-Linux.deb

[bphanguyen]

Dear developers,

I'd like to install JSCIPOpt referencing debian package SCIPOptSuite-5.0.1-Linux.deb on a Linux Debian machine, installing SCIPOptSuite-5.0.1-Linux.deb with dpkg is ok,
but I can’t figure out how to refer to installed files (listed by command : dpkg -c SCIPOptSuite-5.0.1-Linux.deb) when compiling JSCIPOpt with Cmake.

I don’t know what path to refer in the option -DSCIP_DIR in the command
$ cmake .. -DSCIP_DIR=/build
(following tutorial https://github.com/SCIP-Interfaces/JSCIPOpt/blob/master/INSTALL.md)

Maybe I’m missing or not understand something.

After compiling with :
$ cmake .. -DSCIP_DIR=/usr/include (for example, the repository where the .h SCIP files are placed)

I tried :
$ make

And that failed at first step :

Logs in English:

Scanning dependencies of target jscip
[10%] Building C object CMakeFiles / jscip.dir / src / scipjni_wrap.c.o
make [2]: *** No rules for making the "libscip-NOTFOUND" target, needed for "Release / libjscip.so". Stop.

make [1]: *** [CMakeFiles / jscip.dir / all] Error 2
Makefile: 83: the recipe for the "all" target has failed
make: *** [all] Error 2

Please kindly let me know if there is a Debian package for JSCIPOpt and how to refer to installed files of SCIPOptSuite-5.0.1-Linux.deb

Please let me know if you need further information.

Thank you very much beforehand,

Best regards,

Hi

Can you try any of the following three options for compiling JSCIPOpt please

1. cmake ..
2. cmake .. -DSCIP_DIR=/usr/
3. cmake .. -DSCIP_DIR=/usr/lib/

[bphanguyen]

Hi,

Thanks for your reply.

I tried the 3 of them, resulting in the same error after with command make :

1. First with 'cmake' :

   -- The CXX compiler identification is GNU 6.3.0

   -- Configuring done
   -- Generating done

With the logs =

message("${JNI_INCLUDE_DIRS}") = /usr/lib/jvm/java-8-openjdk-amd64/include;/usr/lib/jvm/java-8-openjdk-amd64/include/linux;/usr/lib/jvm/java-8-openjdk-amd64/include
message("${SCIP_INCLUDE_DIRS}") = /usr/lib/cmake/scip/../../../include
==> /usr/include
message("${PROJECT_SOURCE_DIR}") = /myrepo/JSCIPOpt

2. Then with 'make' :
   Scanning dependencies of target jscip
   [10%] Building C object CMakeFiles / jscip.dir / src / scipjni_wrap.c.o
   make [2]: *** No rules for making the "libscip-NOTFOUND" target, needed for "Release / libjscip.so". Stop.
   CMakeFiles / Makefile2: 67: the recipe for the target "CMakeFiles / jscip.dir / all" failed
   make [1]: *** [CMakeFiles / jscip.dir / all] Error 2
   Makefile: 83: the recipe for the "all" target has failed
   make: *** [all] Error 2

As you can see, the included directories for SCIP library ${SCIP_DIR} and ${SCIP_INCLUDE_DIRS} always point to the same directories : /usr/lib/cmake/scip and /usr/lib/cmake/scip/../../../include
(==> /usr/include).
I suspect the option ${SCIP_DIR} (-DSCIP_DIR) are not taken into account when pointing to another folder than the standard process :
$ cmake .. -DSCIP_DIR=/build

[fserra]

mmm so apparently libscip is not being found, which is weird. I don't really know. I am guessing you did mkdir build; cd build; cmake .. -D..... I would try again, removing build and trying cmake ...

Otherwise, I would download the SCIPOptSuite-5.0.1-Linux.sh: Linux self-extracting archive; including SoPlex, ZIMPL, Ipopt, CppAD, zlib, GMP, bliss and put the scipoptsuite in a local directory and use that one for -DSCIP_DIR=

[bphanguyen]

Thanks for your reply.
Yes I followed the steps in the INSTALL.md : 2a) Building JSCIPOpt on Linux.

I'm trying the mentionned ways and inform you about the result.

[bphanguyen]

Well, I tried the Linux self-extracting archive and refer to the local repo for
-DSCIP_DIR=/path_to/SCIPOptSuite-5.0.1-Linux

Then I tried : $ make -d (for debug level all) which display :

So, in file /path_to/JSCIPOpt/build_sh/CMakeFiles/jscip.dir/build.make at line L143, there's a checkpoint :
Release/libjscip.so: libscip-NOTFOUND

I then replace the line 143 with :
Release/libjscip.so: /path_to/SCIPOptSuite-5.0.1-Linux/lib/libscip.so.5.0.1.0

Then $make -d displays :

make: *** [all] Error 2

Then I come accros the file : /path_to/JSCIPOpt/build_sh/CMakeFiles/jscip.dir/link.txt
And change in this link.txt file the keyword libscip-NOTFOUND by the absolute path to libscip.so :
/path_to/SCIPOptSuite-5.0.1-Linux/lib/libscip.so.5.0.1.0

Then everything works fine! All the steps programmed for the $ make operation go successful.
And I'm even able to run the Java jars examples :
$ cd /path_to/JSCIPOpt/build_sh/Releases
$ java -Djava.library.path=. -cp scip.jar:examples.jar Linear ==> OK!

I then guess that the problem is from the CMake step (of JSCIPOpt).
The dependency Release/libjscip.so couldn't be resolve at some point and replace the full path to libjscip.so (SCIPOptSuite-5.0.1-Linux/lib/libscip.so.5.0.1.0) by the keyword libscip-NOTFOUND, in the above mentionned files build.make and link.txt

Could you please check that issue, why the dependency Release/libjscip.so couldn't be resolve when refering to SCIPOptSuite installed files, installed either through Debian package or Linux self-extract archive?

Thank you very much!

Ok I tried to install it myself and also had problems. So apparently you must compile SCIP (I am talking linux here) with cmake, because you have to point to the build directory like specified in the instructions

[bphanguyen]

Hi!
In my dev env, I can compile SCIP with cmake like the suggested instructions. But not in the real work env because of limitations policies.
I'm still able to use SCIP+JSCIPOpt with the above described steps by pointing specifically to the missing files.

Does the solving of this issue in your roadmap?

Thank you very much in advance for your reply.

[fserra]

I guess @mueldgog would have to have a look at the issue. He is currently unavailable but I think he would be interested to fix this. After all is very strange that it only works from a compiled SCIP and not an installed one.

[bphanguyen]

Yes, that would be nice.
Please kindly let me know about future development.
Have a nice day!
