Package: gpsim-dev
Version: 0.20.14-7.3
Your package causes build failures in gpsim-lcd, gpsim-logic and
gpsim-led with recent versions of the gcc-snapshot package, i.e. a
pre-release of GCC 4.2. The problem is that external variables are
defined both in a C and C++ context, as you can see in this simple
example:
42059:[EMAIL PROTECTED]: ~] /usr/lib/gcc-snapshot/bin/g++ -c t.cc
t.cc:1: error: previous declaration of 'int i' with 'C++' linkage
t.cc:4: error: conflicts with new declaration with 'C' linkage
42060:[EMAIL PROTECTED]: ~] cat t.cc
extern int i;
extern "C" {
extern int i;
}
The specific example of gpsim-dev is:
1682:[EMAIL PROTECTED]: ~] /usr/lib/gcc-snapshot/bin/g++
-I/usr/include/glib-1.2 -I/usr/lib/glib/include -I/usr/include/gtk-1.2 -c
test.cc
/usr/include/gpsim/pic-processor.h:147: error: previous declaration of 'int
verbose' with 'C++' linkage
/usr/include/gpsim/interface.h:69: error: conflicts with new declaration with
'C' linkage
zsh: exit 1 /usr/lib/gcc-snapshot/bin/g++ -I/usr/include/glib-1.2
-I/usr/lib/glib/include
1683:[EMAIL PROTECTED]: ~] cat test.cc
#include <gpsim/pic-processor.h>
#include <gpsim/interface.h>
1684:[EMAIL PROTECTED]: ~]
According to http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27227#c8 this is
not valid, so please investigate.

Hi
I am unable to reproduce this bug either. I rebuild the gpsim-lcd package with
g++-4.2 without problems.
Therefore, I assume that this problem is gone as well.
Cheers
