Installed gprolog.h cannot be used in C++ programs

[Roberto Bagnara]

Binary package hint: gprolog

Package: gprolog
Version: 1.3.0-3
Severity: important

The file /usr/lib/gprolog-iso/include/gprolog.h of gprolog is supposed to be includable by C++ programs (and in fact, I am doing that routinely with the official distribution of GNU Prolog). However, this cannot be done with the Ubuntu package.

$ fgrep -n -C 3 cplus /usr/lib/gprolog-iso/include/gprolog.h

Is this symptom still reproducible in 8.10?

[Roberto Bagnara (bagnara)]

I don't have access to an 8.10 system right now. But you can check by yourself very easily.
Just try to compile the one-liner

#include </usr/lib/gprolog-iso/include/gprolog.h>

with g++.

You mean you cannot compile the one-liner

#include </usr/lib/gprolog-iso/include/gprolog.h>

with g++ in an 8.10 system and see whether there are compilation errors?
If you can provide me with access to such a system I can do it.
All the best,
