Suggestion for the DarwinPorts version of SWI-Prolog
Hi there,
I may well be missing something, but it seems the life of people interfacing C/C++ and Prolog programs on MacOS would be simplified if SWI-Prolog.h and the other interface header file could be installed in some fixed place, such as /opt/local/include, as well as in /opt/local/lib/swipl-x.y.zz/include. This would match what happens on, e.g., the Linux version where these header files are installed in, say, /usr/local/include as well as in /usr/local/lib/swipl-x.y.zz/include.
Please note that I know _nothing_ about MacOS: I am only trying to support users of the Parma Polyhedra Library, yet minimizing the number of special cases I have to take into account. All the best,
Roberto
P.S. BTW, why /opt/local instead of /usr/local?
Hi Roberto,

On MacOS X, when installing SWI-Prolog using DarwinPorts (including the installers available from the SWI-Prolog web site), the above header files are installed on /opt/local/lib/swipl-x.y.zz/include/. A possible solution would be to create links to the header files on / opt/local/include/.
P.S. BTW, why /opt/local instead of /usr/local?
To ensure that DarwinPorts installed software does not depend or interfere with MacOS X provided software and libraries, creating a nightmare of dependencies (not to mention that upgrading MacOS X can wipe out /usr).
Cheers,

Yes, this is what I meant. What I wanted to say is whether you plan to modify your install procedure so that this link is performed automatically (to match what happens on the Unix/GNU world) or if you think this is the job of third-party software providers, like ourselves.

Thanks for the explanation. Cheers,

I will try to do that for the next SWI-Prolog stable release.

There seams to be some confusion here between the official SWI-Prolog distribution (i.e. the source code tarball) and the DarwinPorts-based installers for MacOS X, which are a user contribution to the SWI- Prolog project. I expect that the above proposed changes will only be applied to the DarwinPorts portfile (which describes a particular way of compiling and installing SWI-Prolog that, btw, tries to follow the DarwinPorts project policy regarding install locations). I do not expect the currently available MacOS X installers to be suitable to everyone. For one thing, they require an administration account, which not all people have, as Richard pointed out.
Cheers,
Paulo
