Cplex Configuration with Eclipse CDT

I am trying to configure the Eclipse CDT with Cplex. I have followed the following steps:

  • Defined the IL_STD preprocessor macro
  • Givent the path of include directories in cplex, opl and concert

  • Given the path of "lib" folder in "concert" "cplex" and "opl" folder

  • I have also given the path of .a and .so files in these directories But now when I try to compile my code, it is not able to find the library and give errors like this:

    g++ -L/home/randomuser/IBMCplex/cplex/lib/x86-64_linux/static_pic -L/home/randomuser/IBMCplex/concert/lib/x86-64_linux/static_pic -o "CplexTest" ./src/CplexTest.o -l/home/randomuser/IBMCplex/concert/lib/x86-64_linux/static_pic/libconcert.a /usr/bin/ld: cannot find -l/home/randomuser/IBMCplex/concert/lib/x86-64_linux/static_pic/libconcert.a collect2: error: ld returned 1 exit status makefile:45: recipe for target 'CplexTest' failed make: *** [CplexTest] Error 1

Can anyone guide me what am I missing here or doing wrong?

Solution

  • The -l option to g++ does not expect a path as argument. It expects a library name, from which it will form a filename by prepending lib, appending .a (or .so for a dynamic library), and then look for that filename in the paths specified with -L.

    So, when entering your library name, instead of using the full path /home/randomuser/IBMCplex/concert/lib/x86-64_linux/static_pic/libconcert.a, you should just enter concert (on the command line it should be -lconcert).
