生成scip.jar（linux）

所以我從這裏得到了scip套裝，make編輯它。然後我去scipoptsuite-3.1.1/scip-3.1.1/interfaces/jni和遵循的自述文件的說明：生成scip.jar（linux）

1) doxygen jniinterface.dxy 
    - generates xml documentation 
2) ./createJniInterface.py xml/* 
    - uses the xml documentation and creates JNI interface 
3) create softlinks to soplex and scip in "lib" folder: 
    mkdir ./lib 
    cd lib 
    ln -s ../../../../soplex-2.0.0 soplex 
    ln -s ../../.. scip 
    cd .. 
4) make soplex 
    - creates shared library of Soplex 
    - use options (e.g., ZLIB=false GMP=false) as required 
5) make scip 
    - creates shared library of SCIP 
    - use options (e.g., ZIMPL=false READLINE=false ZLIB=false GMP=false) 
    as required 
6) make 
7) test your installation: 
    cd examples/JniKnapsack 
    make 
    make run

在結束的時候我做make run，我得到的是以下錯誤：

ub[email protected]:~/solvers/scipoptsuite-3.1.1/scip-3.1.1/interfaces/jni/examples/JniKnapsack$ make run 
./run.sh 
java: symbol lookup error: /home/ubuntu/solvers/scipoptsuite-3.1.1/scip-3.1.1/interfaces/jni/lib/libjscip-0.1.linux.x86_64.gnu.opt.spx.so: undefined symbol: SCIPcreate 
make: *** [run] Error 127

不知道如何解決這個問題？

在某些時候，我遇到了make的一些問題。我必須將包含jni.h的文件夾作爲「-I」選項添加到Makefile中的gcc。

這裏是GCC版本號：

請嘗試更改接口/ JNI/Makefile中的規則$（JNILIBFILE）爲

$(JNILIBFILE): $(OBJDIR) $(JNILIBHEADERS) $(JNILIBDEP) $(JNILIBOBJFILES) 
      @echo "-> generating library [email protected]" 
      -rm -f [email protected] 
      $(LIBBUILD) $(LIBBUILDFLAGS) $(LIBBUILD_o)[email protected] \ 
      $(JNILIBOBJFILES) \ 
      $(LINKCC_L)$(LIBDIR)/ $(LINKCC_l)$(SCIPLIB)$(LINKLIBSUFFIX) \ 
      $(LINKCC_l)$(LPILIB)$(LINKLIBSUFFIX) \ 
      $(LINKCC_l)$(NLPILIB)$(LINKLIBSUFFIX) \ 
      $(LPSLDFLAGS) $(LDFLAGS) 
ifneq ($(RANLIB),) 
      $(RANLIB) [email protected] 
endif
