[ghemical-devel] build error with gcc-3.2(?)

[Michael Banck]

Hi,

As mpqc is now rebuilt with gcc-3.2 in debian and the old libsc2-library
gone, I had to rebuild ghemical against the latest libsc4. Unfortunately,
I was not very successful...

The first problem was in /src/target3/t3views.h. It #includes gnome.h,
which by itsself seems to #include libintl.h since lately, so this
resulted in a sytax error:

 In file included from
 /usr/include/c++/3.2/i386-linux/bits/c++locale.h:39,
                  from /usr/include/c++/3.2/bits/localefwd.h:46,
                  from /usr/include/c++/3.2/ios:48,
                  from /usr/include/c++/3.2/ostream:45,
                  from /usr/include/c++/3.2/iostream:45,
                  from ../../src/common/typedef.h:20,
                  from ../../src/common/v3d.h:17,

                  from ../../src/graphics/camera.h:34,
                  from ../../src/graphics/mtools.h:42,
                  from ../../src/graphics/views.h:39,
                  from t3views.h:28,
                  from t3main.h:19,
                  from t3main.cpp:10:
 /usr/include/libintl.h:40: syntax error before `__const'
 /usr/include/libintl.h:44: syntax error before `__const'
 /usr/include/libintl.h:52: syntax error before `__const'
 /usr/include/libintl.h:81: syntax error before `__const'
 /usr/include/libintl.h:86: syntax error before `__const'

I got the suggestion to comment out the #include gnome.h in t3views.h,
wich helped to build ghemical (see http://bugs.debian.org/182251 for a
bit of further discussion about this) 

The second and more severe problem is that ghemical segfaults as soon as
I want to File->New anything. Here is the backtrace:

t3docv.cpp:91 says:

	gnome_docv * docv2 = dynamic_cast<gnome_docv *>(docv1);

and I get a segfault in gdb as soon as I step over that line.

I can post the versions of the packages I've installed in order to build
ghemical if somebody wants them, but the list is *big* :)

All those packages should be compiled with gcc-3.2 by now, so perhaps
the problem lies there, i.e. ghemical has issues with gcc-3.2? OTOH, the
list of packages is big, so the error could well be in one of them, or
even connected with the commenting out of #gnome.h above?

thanks for any hint,

Michael
