"cannot find stddef.h" error when compiling Ipopt example in ubuntu 16.04

I installed Ipopt debian package in ubuntu 16.04. When I tried to do an example problem given in the Ipopt documentation, I'm getting the following error

/usr/include/coin/IpSmartPtr.hpp:18: error: #error "don't have header file for stddef"

I hope some it is some dependency issue. How do I solve this?

Solution

  • I can work around this by either doing

    #define HAVE_CSTDDEF
#include <IpTNLP.hpp>
#undef HAVE_CSTDDEF

    or

    #define HAVE_STDDEF_H
#include <IpTNLP.hpp>
#undef HAVE_STDDEF_H
