Re: [PPL-devel] Problems with ppl-0.10.2 and g++ 4.4.0 on Open Solaris (x86_64)
(sorry for the broken thread, I haven't subscribed to the list)
apparently, some of the header files in your system are broken. For example, here is line 69 in src/Pointset_Powerset.defs.hh:
typedef Powerset<CS> Base;
I bet that you have an header file containing something like
#define CS 15
Can you please check that?
He does, in sys/regset.h. And so does linux (actually glibc) on x86(_64) in sys/reg.h (but CS is either 13 or 17 there). The only difference is that the libstdc++ headers end up accidentally including it on solaris and not on linux. It sucks, but I guess it would be nice to occasionally build PPL and run the testsuite on linux on a PC with CPPFLAGS='-include sys/reg.h'. -- Marc Glisse

Hi Marc, we will certainly follow your suggestion. Unfortunately, this seems very "ad hoc". In other words, I wonder if there are other header files that may give rise to similar problems, and which macros are they defining.

I completely agree, hence my "it sucks". Note that this kind of extreme pollution is considered a bug, see: http://bugs.opensolaris.org/view_bug.do?bug_id=6400595 I know it affected at some point at least PPL, CGAL and freetype. Maybe it will eventually be fixed... (it does not look like a lot of work) But indeed, conflicting C headers, especially when it comes to macros, are a never ending problem. -- Marc Glisse
