problem when trying to install

[posseidon23]

at the "make" step, I get the error message : "./../../FlopCpp/src/MP_set.hpp:220:22: error: no matching constructor for initialization of 'flopc::MP_domain' return MP_domain(s);}"

does anybody know how to fix?

From the error, I'm guessing you're building on OS X. FlopCpp doesn't build on OS X with clang and I haven't been able to figure out a fix. Unless you are specifically interested in using FlopCpp, the fix is just to skip building it by configuring with the argument COIN_SKIP_PROJECTS=FlopCpp. Let me know if this fixes the problem.

In the next couple of days, I'll try to update the README with better instructions on building. The most detailed and up-to-date instructions are in the slides for a course I recently gave on Computational MILP, starting around slide 16 here:

http://coral.ie.lehigh.edu/~ted/files/computational-mip/lectures/Lecture3.pdf

The instructions for SYMPHONY here can also be modified for the Optimization Suite.

Thank you professor, yes I am building from OS X.
I tried your suggestion, but had this at the end of 'make test' : "....... 128 warnings generated. make[4]: * No rule to make target /Coin-Or/build/Couenne/src/main/libBonCouenne.la', needed byOSSolverService'. Stop. make[3]: * [all-recursive] Error 1 make[2]: * [all] Error 2 make[1]: * [all-recursive] Error 1 make: *\ [all-recursive] Error 1 "

Hmm, this error looks familiar, but it seems to me that I fixed this problem. What version of the Optimization Suite are you building? And how did you get the source? Also, what is the compiler and compiler version and what OS X version? Actually, if you could just give the full configure command that you used, that would be helpful to replicate. I'm also going to set up a Travis build, which I should have done already.

Hi professor Ralph, thanks for answering. ok, the version I am trying to install is coin Optimization suite 1.7. I downloaded it with subversion. Actually, when I try to install the components individually, it works, at least cbc, clp, symphony(the one I need most), but I wanted something that links them, that is why I am trying to install the optimization suite. For the configure command is : (I created the directory build, enter build and run the following command): _../configure COIN_SKIP_PROJECTS=FlopCpp._ the compiler is : clang 7.3.0 Well I am not proficient in shell command, so whenever I find instruction, I try to run it as is described . Maybe the version matters, as I started to build the 1.7 version I realized there was a more recent one (1.8), I downloaded this latter, but did it not work, the message I have is : error: source directory already configured; run "make distclean" there first (which I did), but maybe I have to remove it.

I would just delete the entire source directory and download version 1.8 into a clean directory, then build everything there and it should work.

Thanks professor, yes it works.
