installing the JSCIPopt

[soukaina18]

PLz I need help!

I have an issue at 3a) step of the Install.md file . To my mind the principals errors are:

1. CMake Error at CMakeLists.txt:18 (include): include could not find load file: UseJava

2. found SCIP library: SCIPOPT_LIBRARIES-NOTFOUND CMake Error at CMakeLists.txt:96 (add_jar): Unknown CMake command "add_jar".

here is the full output:

~$ cd JSCIPOpt-master ~/JSCIPOpt-master$ rm -rf build ~/JSCIPOpt-master$ mkdir build ~/JSCIPOpt-master$ cd build ~/JSCIPOpt-master/build$ cmake .. -- The C compiler identification is GNU -- The CXX compiler identification is GNU -- Check for working C compiler: /usr/bin/gcc -- Check for working C compiler: /usr/bin/gcc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Check for working CXX compiler: /usr/bin/c++ -- Check for working CXX compiler: /usr/bin/c++ -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Found JNI: /usr/lib/jvm/default-java/jre/lib/amd64/libjawt.so -- Java version 1.7.0.85 configured successfully! -- Found Java: /usr/bin/java (found version "1.7.0.85") CMake Error at CMakeLists.txt:18 (include): include could not find load file: UseJava

You need to execute the following commands:

cd TheDirectoryOfJSCIPOpt
mkdir lib; cd lib
ln -s /home/soukaina/scipoptsuite-4.0.0/scip-4.0.0/src scipinc
ln -s /home/soukaina/scipoptsuite-4.0.0/lib/libscipopt.so libscipopt.so
cd ..
mkdir build; cd build
cmake ..
make

Thank you sooo much!

I executed the commands and I got the message bellow... I think( Just thinking) that now it's a Java JDK problem, I tried to install it as you mentioned before following this Tutoriel https://stackoverflow.com/questions/14788345/how-to-install-jdk-on-ubuntu-linux

but the 8 version refused to be installed I managed to install the 7 version, a lot of packages have been installed but I think since a old version is already there something went wrong nothing really happened, I was afraid to uninstall the old one and not be able to install the new version since I not a developer and so new to Linux environment.

Could you call locate jni.h and see whether the output looks like

/usr/lib/jvm/java-7-openjdk-amd64/include/jni.h

? If this is not the case, please check (manually) whether the file exists in the directory or not.

[soukaina18]

First of all, sorry for repeating this issue. I don't have too much experience with compilers, so sorry again.

Manuall,y I found the jni.h here: /usr/lib/jvm/java-8-openjdk-amd64/include

I just installed the Java-8-openjdk and got :

And then , I tried the cmake .. augain in the JSCIPOpt file and this time I got this:

$ rm -rf build soukaina@soukaina-Aspire-5250:~/JSCIPOpt-master$ mkdir build soukaina@soukaina-Aspire-5250:~/JSCIPOpt-master$ cd build soukaina@soukaina-Aspire-5250:~/JSCIPOpt-master/build$ cmake .. -- The C compiler identification is GNU -- The CXX compiler identification is GNU -- Check for working C compiler: /usr/bin/gcc -- Check for working C compiler: /usr/bin/gcc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Check for working CXX compiler: /usr/bin/c++ -- Check for working CXX compiler: /usr/bin/c++ -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Found JNI: /usr/lib/jvm/default-java/jre/lib/amd64/libjawt.so CMake Warning at /usr/local/share/cmake-2.8/Modules/FindJava.cmake:118 (message): regex not supported: openjdk version "1.8.0_131"

I may be mistaken, but I think that the cmake installation is missing the UseJava module for some reason, manually, I found the UseJava installed in: /usr/share/cmake-2.8/Modules/UseJava.cmake. But why the path is not recognized .....what I need to do PL ?

I found in internet that a need to set the JAVA_HOme =/usr/lib/jvm/jdk1.8 or to do this command :

export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64 cmake -DBUILD_SHARED_LIBS=OFF ..

but I'm not sure

CMake 2.8 is quite old and probably this issue has been fixed with a newer version. Could you upgrade your CMake and test this again?

[soukaina18]

Thank you so much Benjamin, words can not describe how thankful I'am right now!!!! Thanks

I upgrade the Cmake version to the lastest one cmake-3.9.0 and everything went fine as follow:

[soukaina18]

One more thing plz, how can I use this ....

Execute the examples via

• export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:./ # ****do I copy this to terminal or Ido I need to add a specific path

• java -cp scip.jar:examples.jar <"Linear" or "Quadratic" or "Read">

Last question plz (really the Last), now that the " sciplib.so" and "scip.jar" are genereated, Can I use them through Eclips or Netbeans in JavaApplication project as library,,Or I'm mistaken!

Best regards !

Yes, this should be possible. You need to include the jar to your project and add the path to the JSCIPOpt build to your LD_LIBRARY_PATH variable, e.g., into your ~/.bashrc. The libscipopt.so might be copied somewhere into your java project that contains the compiled java files (or the directory above?).

First, please try do it on your own and if you don't succeed then I will have a look, but right now I am too busy in order to dig into it. Of course, let me know if you accomplished something and I will update of JSCIPOpt accordingly.

Cheers, Benjamin

[soukaina18]

I will try my best and I will keep you posted!

Again Thank a billion for your precious help, time, and patience ! You are the best ^_^

Much respect!

Kind regards
