Thanks for the reply.
There are several things I did:
- upgraded to a newer OpenBSD snapshot
- after encountering a similar error with that file
I found another version in
/usr/local/lib/gcc/x86_64-unknown-openbsd6.0/4.9.4/include/
(from eg++)
By hacking the Makefiles where a mmintrin.h related error happens
the compilation succeeds:
GI=/usr/local/lib/gcc/x86_64-unknown-openbsd6.0/4.9.4/include
INCPATH = -I. -I../../../include -I../../../include/QtFontDatabaseSupport
-I../../../include/QtFontDatabaseSupport/5.8.0
-I../../../include/QtFontDatabaseSupport/5.8.0/QtFontDatabaseSupport
-I../../../include/QtGui/5.8.0 -I../../../include/QtGui/5.8.0/QtGui
-I../../../include/QtCore/5.8.0 -I../../../include/QtCore/5.8.0/QtCore
-I../../../include/QtGui -I../../../include/QtCore -I.moc -I/usr/X11R6/include
-I/usr/X11R6/include/libdrm -I/usr/X11R6/include/freetype2 -I/usr/X11R6/include
-I/usr/X11R6/include/freetype2 -isystem $(GI) -isystem /usr/include -isystem
/usr/local/include -I../../../mkspecs/openbsd-g++
That is, add GI=... and change INCPATH to include the eg++ location:
:.s;-isystem /;-isystem $(GI) &;
I don't know if this a problem with
- qmake generating a wrong INCPATH (-isystem /usr/include etc)
- eg++ not using its own include directory first
- or something else
?
Later on I ran into this error:
../../../3rdparty/assimp/code/BlenderTessellator.cpp: In member function
'Assimp::Blender::PointP2T&
Assimp::BlenderTessellatorP2T::GetActualPointStructure(p2t::Point&) const':
../../../3rdparty/assimp/code/BlenderTessellator.cpp:378:65: error: invalid
cast from type 'std::nullptr_t' to type 'Assimp::Blender::PointP2T*'
reinterpret_cast<uint8_t*>(&( reinterpret_cast< Class* >( NULL )->*(
&Class::Member ) )) - \
^
../../../3rdparty/assimp/code/BlenderTessellator.cpp:383:29: note: in expansion
of macro 'OffsetOf'
unsigned int pointOffset = OffsetOf( PointP2T, point2D );
and the comment in the file says:
// Yes this is filthy... but we have no choice
I redefined OffsetOf() to offsetof() which fixed that compilation
error (and hopefully generates the intended code).
And after the build finally ended, I noticed that the webengine
module was missing... "not supported" -- it would have been nice
if that info would be in the configure output (well, maybe it is,
but not in an obvious way).
