正在生成 scip.jar 文件（mac）

Question

所以我从这里得到了 scip 套装并 make 编辑了它。然后我去了 scipoptsuite-3.1.1/scip-3.1.1/interfaces/jni 并按照自述文件中的说明进行操作：

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

一切正常，直到 make soplex，我看到以下错误。任何的想法？

问题是您的系统缺少 "gmp"。您有两个选择：

安装 gmp 库
不使用 gmp 编译 SoPlex。做这个电话： make soplex GMP=false

zlib 可能会出现类似的问题。如果您的系统上未安装此库。如果是这种情况，您可以使用 make soplex GMP=false ZLIB=false

下一步会要求你编译SCIP。如果没有安装gmp，需要使用如下命令：make scip GMP=false ZIMPL=false
