--- Begin Message ---Package: lesstif2-dev Version: 0.94.4-2 About 7 packages [1] in the archive fail to build with recent versions of the gcc-snapshot package, i.e. a pre-release of GCC 4.2 because of a conflict between lesstif2-dev and libxt-dev. The problem is that external variables/functions 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; } According to http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27227#c8 this is not valid, so please investigate. The problem is that the lesstif header explicitly uses 'extern "C"' when it is in C++ mode, but this seems bogus. Can you talk to upstream to see why this was added? Here's a trivial example of the problem: 1707:[EMAIL PROTECTED]: ~] cat test.cc #include <Xm/VendorSP.h> 1708:[EMAIL PROTECTED]: ~] /usr/lib/gcc-snapshot/bin/g++ -c test.cc /usr/include/X11/VendorP.h:87: error: previous declaration of 'VendorShellClassRec vendorShellClassRec' with 'C++' linkage /usr/include/Xm/VendorSP.h:58: error: conflicts with new declaration with 'C' linkage zsh: exit 1 /usr/lib/gcc-snapshot/bin/g++ -c test.cc 1709:[EMAIL PROTECTED]: ~] The following patch makes the build failure go away: --- /usr/include/Xm/VendorSP.h 2006-07-07 15:58:04.000000000 +0200 +++ VendorSP.h 2006-07-07 15:58:19.000000000 +0200 @@ -30,10 +30,6 @@ #include <Xm/VendorS.h> #include <X11/ShellP.h> -#ifdef __cplusplus -extern "C" { -#endif - XMLIBEXPORT extern Cardinal _XmFilterResources(XtResource *resources, Cardinal numResources, WidgetClass filterClass, @@ -57,9 +53,4 @@ XMLIBEXPORT extern VendorShellClassRec vendorShellClassRec; - -#ifdef __cplusplus -} -#endif - #endif /* _XM_VENDORSP_H */ > Automatic build of xmpi_2.2.3b8-10 on test.track.rz.uni-augsburg.de by > sbuild/powerpc 0.47 ... > if mpic++.lam -DHAVE_CONFIG_H -I. -I. -I. -I../../src -g -O2 -MT > xmpi_misc.o -MD -MP -MF ".deps/xmpi_misc.Tpo" \ > -c -o xmpi_misc.o `test -f 'xmpi_misc.cc' || echo './'`xmpi_misc.cc; \ > then mv -f ".deps/xmpi_misc.Tpo" ".deps/xmpi_misc.Po"; \ > else rm -f ".deps/xmpi_misc.Tpo"; exit 1; \ > fi > /usr/include/X11/VendorP.h:87: error: previous declaration of > 'VendorShellClassRec vendorShellClassRec' with 'C++' linkage > /usr/include/Xm/VendorSP.h:58: error: conflicts with new declaration with 'C' > linkage > make[3]: *** [xmpi_misc.o] Error 1 > make[3]: Leaving directory `/build/tbm/xmpi-2.2.3b8/src/xmpi' [1] At the moment, the following packages fail to build with GCC 4.2: ddd_1:3.3.11-1 dx_1:4.4.0-2 inventor_2.1.5-10-9 tcm_2.20+TSQD-3 twpsk_2.1+2.2beta1-7 xmpi_2.2.3b8-10 xpdf_3.01-8 -- Martin Michlmayr http://www.cyrius.com/
