>  The INSTALL.md look like :....to use/extend the Java interface, you need:  
 - SCIP optimization suite
 - Java JDK
 - C compiler
 - CMake
 - SWIG (optional)

The following steps need to be done before compiling the Java interface.   
1) Create a shared library of the [SCIP optimization suite](http://scip.zib.de/#download) by executing     
    make SHARED=true scipoptlib     
in the SCIP optimization suite directory. Afterwards, you will find the library (*.so) in the ./lib directory of the
optimization suite.

2) Create a symbolic link in JSCIPOpt to the library compiled in 1) and to the source directory of SCIP (in the
optimization suite)

    mkdir -p lib;
    cd lib;
    ln -s <SCIP source directory> scipinc
    ln -s <SCIP opt suite directory>/lib/<scip opt library> libscipopt.so

**3a)** Building JSCIPOpt on Linux.

Compile the interface by executing the following commands:

 - mkdir build
 - cd build
 **- cmake .. [-DCMAKE_BUILD_TYPE=<"Debug" or "Release", default:** "Release">]
 - make

Execute the examples via

 - export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:./
 - java -cp scip.jar:examples.jar <"Linear" or "Quadratic" or "Read">

>INSTALL.md看起来像：……要使用/扩展Java接口，您需要：
-SCIP优化套件
-Java JDK
-C编译器
-克马克
-SWIG（可选）
在编译Java接口之前，需要执行以下步骤。
1） 创建[SCIP优化套件]的共享库(http://scip.zib.de/#download)通过执行
使共享=真正的scipoptlib
在SCIP优化套件目录中。之后，您将在的./lib目录中找到库（*.so）
优化套件。
2） 在JSCIOPT中创建一个符号链接，指向在1）中编译的库和SCIP的源目录（在
优化套件）
mkdir-p-lib；
光盘库；
ln-s scipinc
ln-s/lib/libscipopt.so
**3a）**在Linux上构建JSCIPOpt。
通过执行以下命令编译接口：
-mkdir构建
-光盘制作
**-克马克。。[-DCMAKE\u BUILD\u TYPE=]
-制造
通过以下方式执行示例：
-导出LD\u库路径=$LD\u库路径：/
-java-cp scip.jar:examples.jar

非常感谢您的帮助…请记住，在回答时，我不是一个成熟的开发人员。提前感谢

您的

jsciopt/lib

目录的内容是什么样子的？您是否有指向SCIP源目录的符号链接和指向

libscipot.so

的其他符号链接？您能下载并安装最新版本的Java JDK吗

我还认为你误解了

cmake .. [-DCMAKE_BUILD_TYPE=<"Debug" or "Release", default: "Release">]

您没有正确设置符号链接。基本上，您需要执行以下命令：

cd JSCIPOpt
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

好的，在格式化输出后，我看到cmake在

JSCIPOpt/lib

目录中找不到libscipopt.so。请确保您已遵循1。二,。JSCIPOpt中INSTALL.md文件的要点。首先，非常感谢您的回复。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。然后，当我放置“make SHARED=true scipptlib”时，我得到了两个文件：libscipot.so&libscipopt-4.0.0.linux.x86_64.gnu.opt.so…….PLZ，当你说指向源目录时，这是不是意味着路径“sciptsuite-4.0.0/scip-4.0.0/src”，，，，，，，，，，，，，，，，，，，，，，指向libscipopt的第二个符号链接。所以我这样键入：“ln-s/home/soukaina/scipoptsite-4.0.0/lib/libscippt libscippt.so”我在上面的回答中添加了您需要执行的命令。

cd JSCIPOpt
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
