makefile example to use soplex

Question

I'm trying to link soplex (the infinite precision LP solver of SCIP) in my C/C++ code. I managed to install soplex in my linux machine and from the command line it works.

My problem is that I do not manage to link it in my code:

I'm currently using a normal makefile in which I've put:

#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

but when I try to compile it gives me a series of errors:

I think that there must be a problem linking the libraries of gmp, can anybody please help me?

The library gmp is here:

fabio@canarino3:~/Dropbox/WORKING/SETUP_BPP_CODE/soplex-5.0.1/buid$ grep gmp soplex-targets.cmake 
  INTERFACE_LINK_LIBRARIES "/usr/lib/x86_64-linux-gnu/libz.so;/usr/lib/x86_64-linux-gnu/libgmp.so;/usr/lib/x86_64-linux-gnu/libgmpxx.so;quadmath"
  INTERFACE_LINK_LIBRARIES "/usr/lib/x86_64-linux-gnu/libz.so;/usr/lib/x86_64-linux-gnu/libgmp.so;/usr/lib/x86_64-linux-gnu/libgmpxx.so;quadmath"

I've built soplex from source, dowloaded from the scip webpage

Do you have an example of makefile in which soplex is linked?

MANY THANKS!!!!

Check where `libgmp` is. Maybe the linker does not find it or finds a wrong version. How did you install soplex? Built from source? Please [edit] your question to answer or to add information or clarification. — Bodo, Sep 15 '20 at 18:22
many thanks, I've updated my question, I've installed gmp using the apt-get install functions and I've built soplex from source. — fabio, Sep 15 '20 at 18:34
Specifying libraries with absolute path in `INTERFACE_LINK_LIBRARIES` looks strange, but that's probably not related to your problem. I think the order of the libraries is wrong. Try changing the order in `LP_LIBS`: `-lgmp` after `-lsoplex` — Bodo, Sep 15 '20 at 19:21
also with the suggested order I have the same error:LP_LIBS = -L$(CPLEXLIBDIR) -lilocplex -lcplex -lm -lpthread -ldl -L$(GRBLIBDIR) -lgurobi90 -L$(SOPLEX_DIR) -lsoplex -lgmp — fabio, Sep 15 '20 at 19:34
Please add all information to the question. Show what you have tried in your Makefile and the resulting command and error message. I just noticed that you specified `libgmp.so` and `libgmpxx.so` in `soplex-targets.cmake`. Try `-lgmp -lgmpxx`. — Bodo, Sep 16 '20 at 07:19
