Is there any chance of also including a package for sIPOPT?

Best regards,

I don't know if this is the right place on which to report issue on the debian packages, but I am not very familiar with the process of reporting bug in debian. If you prefer that I report this issue in the debian bug tracker, just let me know.

HAVE_CSTDDEF issue

Debian-packaged IPOPT need the downstream users of IPOPT to manually define (or automatically if they are using pkg-config) the HAVE_CSTDDEF symbol.
This is creating issues in several downstream projects :

• casadi/casadi#1010
• robotology/robotology.github.io#3

The requirement of HAVE_CSTDDEF is inserted by the debian packaging in https://github.com/ghorn/debian-coinor-ipopt/blob/master/debian/patches/add_missing_cstddef.patch , but the preprocessor logic is totally unnecessary: that header is a C++ header, so to fix the issue (not defined NULL) it is sufficient to just add an #include <cstddef>, because the cstddef is a standard C++98 header that is present in all existing C++ standard libraries in the planet, as far as I know.

Missing dependencies

The pkg-config file is reporting the -lblas -llapack as flags to pass to the linker, but libblas-dev and liblapack-dev are not in the dependencies of the coinor-libipopt-dev package.
