C++ 使用soplex的makefile示例

我试图在我的C/C++代码中链接soplex（SCIP的无限精度LP解算器）。我设法在我的linux机器上安装了soplex，并从命令行开始工作

我的问题是我无法在代码中链接它：

我目前使用的是一个普通的makefile，其中我放了：

#sopleX HERE
SOPLEX_DIR =  /home/fabio/Dropbox/WORKING/SETUP_BPP_CODE/soplex-5.0.1/buid/lib
SOPLEX_INCLUDE= /home/fabio/Dropbox/WORKING/SETUP_BPP_CODE/soplex-5.0.1/src

LP_LIBS = -L/usr/lib/x86_64-linux-gnu/ -lgmp  -L$(CPLEXLIBDIR) -lilocplex -lcplex  -lm -lpthread -ldl  -frounding-math -L$(GRBLIBDIR) -lgurobi90 -L$(SOPLEX_DIR)  -lsoplex 

DBG= -O3 -DIL_STD

INCDIR = -I. -I$(LP_INCLUDE) -I/usr/local/include -I$(GRB_LP_INCLUDE) -I$(SOPLEX_INCLUDE)

CXXFLAGS =  $(DBG) $(INCDIR) 

.c.o:
    gcc -c $(CXXFLAGS) $< -o $@

#LDLIBS = $(CONCORDE_LIBS) $(MY_LIBS) $(LP_LIBS) 
#LDLIBS = $(CONCORDE_LIBS) $(LP_LIBS) 
LDLIBS = $(LP_LIBS)

all:BPPS

BPPS: $(OBJS)
        $(CXX) $(CXXFLAGS) -o $@ $(OBJS) $(LDLIBS)

$(OBJS): Makefile

clean:
    rm -f $(OBJS) rm BPPS

我从源代码构建了soplex，从scip网页下载

您是否有一个链接soplex的makefile示例

---

非常感谢

检查

libgmp

的位置。可能链接器没有找到它，或者找到了错误的版本。你是如何安装soplex的？源代码构建？请回答您的问题或添加信息或澄清。非常感谢，我已更新了我的问题，我已使用apt get install函数安装了gmp，并从源代码构建了soplex。在

接口链接库中指定具有绝对路径的库看起来很奇怪，但这可能与您的问题无关。我认为图书馆的顺序是错误的。尝试在
-lsoplex
之后更改
LP_LIBS
中的顺序：
-lgmp
同样使用建议的顺序，我也有相同的错误：LP_LIBS=-L$（CPLEXLIBDIR）-lilocplex-lcplex-lm-lpthread-ldl-L$（GRBLIBDIR）-lgurobi90-L$（SOPLEX_DIR）-lsoplex-lgmp请将所有信息添加到问题中。显示您在Makefile中尝试的内容以及生成的命令和错误消息。我刚刚注意到您在
soplex targets.cmake
中指定了
libgmp.so
和
libgmpxx.so
。试试
-lgmp-lgmpxx
。
