Trying to rebuild Ekiga in current Rawhide is failing, even after letting most of the rest of the mass-rebuild process shake out. There's a gigantic pile of errors, but they're all something to do with a clash in function definition between boost and the GCC 4.8 headers, I think. There's lots of "error: template with C linkage" in files in /usr/include/c++/4.8.0 . See http://kojipkgs.fedoraproject.org//work/tasks/6639/5026639/build.log , my scratch build attempt. Sample errors: In file included from /usr/include/c++/4.8.0/utility:69:0, from /usr/include/boost/config/no_tr1/utility.hpp:21, from /usr/include/boost/config/select_stdlib_config.hpp:37, from /usr/include/boost/config.hpp:40, from /usr/include/boost/smart_ptr.hpp:17, from ../../lib/engine/framework/services.h:43, from ../../lib/engine/addressbook/contact-core.h:39, from ../../plugins/evolution/evolution-contact.h:49, from ../../plugins/evolution/evolution-contact.cpp:40: /usr/include/c++/4.8.0/bits/stl_relops.h:85:5: error: template with C linkage template <class _Tp> ^ /usr/include/c++/4.8.0/bits/stl_relops.h:98:5: error: template with C linkage template <class _Tp> ^ /usr/include/c++/4.8.0/bits/stl_relops.h:111:5: error: template with C linkage template <class _Tp> ^ /usr/include/c++/4.8.0/bits/stl_relops.h:124:5: error: template with C linkage template <class _Tp> ^ In file included from /usr/include/boost/config/platform/linux.hpp:15:0, from /usr/include/boost/config.hpp:53, from /usr/include/boost/smart_ptr.hpp:17, from ../../lib/engine/framework/services.h:43, from ../../lib/engine/addressbook/contact-core.h:39, from ../../plugins/evolution/evolution-contact.h:49, from ../../plugins/evolution/evolution-contact.cpp:40: /usr/include/c++/4.8.0/cstdlib: In function 'long long int std::abs(long long int)': /usr/include/c++/4.8.0/cstdlib:174:20: error: declaration of C function 'long long int std::abs(long long int)' conflicts with abs(long long __x) { return __builtin_llabs (__x); } ^ /usr/include/c++/4.8.0/cstdlib:166:3: error: previous declaration 'long int std::abs(long int)' here abs(long __i) { return __builtin_labs(__i); } ^ etc etc etc.
Does this appear with other programs using boost? The error appears in boost...
Nothing else I have installed, all my other packages passed the boost bump rebuild okay. But there may be others that I don't have installed, possibly. We could CC boost maintainers.
Please CC boost maintainers, because I do not know what to do with this bug.
OK! Petr, can you shed any light on this? Thanks!
This doesn't seem to be boost-related. The following is a minimal reproducer: #include <libebook/libebook.h> template <class C> class X {}; }} With this, I get: ../../plugins/evolution/evolution-contact.cpp:2:1: error: template with C linkage template <class C> class X {}; Note the two dangling braces. It seems as if something either in libebook, or transitively included by it, forgets a closing brace in their extern "C".
Yet more minimal test case (but we lost one dangling brace, so chances are there are more instances): #include <camel/camel.h> template <class C> class X {}; }
Created attachment 700137 [details] Fix for this issue This appears to fix the problem. There were indeed two instances of the same issue.
FWIW, the following only returns the two cases that the patch addresses, so this type of issue should really be taken care of now. I checked that there are no instances of the inverse issue (END without BEGIN). $ find /usr/include/evolution-data-server/ -type f -exec grep -q G_BEGIN_DECLS {} \; \( -exec grep -q G_END_DECLS {} \; -o -print \)
Thanks for a bug report. Part of this had been fixed two days ago within: http://git.gnome.org/browse/evolution-data-server/commit/?id=02acf9dc708c3bb2d96db78dae56272ab65ef13c http://git.gnome.org/browse/evolution-data-server/commit/?id=08ddf26463b24bd6da5561256762440502e50af1 and the other part is also dealt upstream, within https://bugzilla.gnome.org/show_bug.cgi?id=694152 I'll backport the upstream changes and build eds with it shortly.
I'm currently building evolution-data-server-3.7.90-3: http://koji.fedoraproject.org/koji/taskinfo?taskID=5039181 I also added patch for IMAPx summary vanish there: https://bugzilla.gnome.org/show_bug.cgi?id=693101 Please reopen in case the build will not work for you. Thanks.
ekiga 4.0.1 now built in rawhide, adam would love feedback on the release
peter: I don't really use it, I only have it installed as part of the GNOME group I think. No-one I know uses anything Ekiga supports any more :/ all video chat seems to be Google Hangouts these days, and the future is WebRTC...
