Make error: install hqp (huge quadratic programming) on OS X

Question

I am trying to install hqp on OS X, but seems the gcc compiler is quite different. When running make, I first come to an error like malloc.h not found, I wrap the #include header like:

#if !defined(__APPLE__)
#include <malloc.h>
#endif

In this way, the first problem is solved. But when I continue to run make, I got things like:

g++ -shared -o libhqp.so Hqp_Init.o Hqp.o sprcm.o Meschach.o spBKP.o matBKP.o bdBKP.o Hqp_impl.o Hqp_Program.o Hqp_Solver.o Hqp_Client.o Hqp_IpsFranke.o Hqp_IpsMehrotra.o Hqp_IpMatrix.o Hqp_IpSpBKP.o Hqp_IpRedSpBKP.o Hqp_IpLQDOCP.o t_mesch.o Hqp_IpSpSC.o meschext_hl.o Hqp_SqpSolver.o Hqp_SqpPowell.o Hqp_SqpSchittkowski.o Hqp_HL.o Hqp_HL_Gerschgorin.o Hqp_HL_DScale.o Hqp_HL_BFGS.o Hqp_HL_SparseBFGS.o Hqp_SqpProgram.o Hqp_Docp.o hqp_solve.o \
          ../meschach/*.o ../iftcl/*.o -L"/sw/lib" -Wl,-rpath,"/sw/lib" -ltclstub8.5
i686-apple-darwin11-llvm-g++-4.2: ../meschach/*.o: No such file or directory
i686-apple-darwin11-llvm-g++-4.2: ../iftcl/*.o: No such file or directory

Does anyone know what component is different this time? I tried reinstall the latest version of tcl, but it seems not to be the problem. Find it really hard to google a solution...

Answer 1

Without actually testing the result, I got this to work using the following steps. I have to say that this set of makefiles does not work as it should, especially with regard to how the dependencies are set up.

First, edit meschach/machine.h and remove the #include <malloc.h>, or make it conditional like you did with the __APPLE__ ifdef. The only reason why malloc.h is included seems to be for malloc() and free() and those get included via stdlib.h anyway.

Then edit makedirs.in and append -I/usr/include/malloc to MES_INCDIR, leaving you with MES_INCDIR = -I.. -I/usr/include/malloc.

With these two steps in place, doing ./configure followed by make should already give you libhqp.so in the lib directory, which might be sufficient for you.

However, there is also an executable called docp in the directory hqp_docp which gets executed during the make process. It does not work because it can not find the shared libary libhqp.so. I resolved that by cd-ing into the lib directory and setting export DYLD_FALLBACK_LIBRARY_PATH=$PWD. I am not sure whether running docp is an essential part of the process though.

Finally, the building of a library called omu breaks because the linker is not passed any reference to the required library libhqp.so. I did not figure out why this would work on other systems, and I do not know whether you need that libomu at all. I just did a quick fix by adding -L../lib -lhqp to the end of the linker-command in omu/Makefile. That is the command starting with $(LD).

I hope I did not forget any of the steps I took, let me know if it still breaks for you somewhere.
