Description of problem: Compiling the apache mod_file failed by error in source code of mapnik-devel file /usr/include/mapnik/mapbox/variant.hpp Version-Release number of selected component (if applicable): - mapnik-devel 3.0.12-1.fc25 - mod_tile from github How reproducible: Download and compile the apache mod_tile from github. Steps to Reproduce: 1. Basics: f25 installation and all dependencies are installed 2. wget https://github.com/openstreetmap/mod_tile 3. cd mod_tile 4. ./autogen.sh 5. ./configure 6. make Actual results: Output: ... /usr/include/mapnik/mapbox/variant.hpp:570:15: Fehler: kein Typ namens »type« in »struct std::enable_if<false, void>« typename Enable = typename std::enable_if<Traits::is_valid>::type> ... Makefile:1135: die Regel für Ziel „src/renderd-gen_tile.o“ scheiterte make[1]: *** [src/renderd-gen_tile.o] Fehler 1 make[1]: Verzeichnis „/home/gisuser/src/mod_tile“ wird verlassen Makefile:1299: die Regel für Ziel „all-recursive“ scheiterte make: *** [all-recursive] Fehler 1 Expected results: compiling without error Additional info: the same procedure works without error with a f24 installation
Well first of I don't speak German so you'll need to tell me what that error is before I can help... Secondly, why do you think this is an issue with mapnik rather than with mod_tile? Fedora 25 has mapnik 3.0.12 while 24 only has 3.0.10 so maybe mod_tile needs fixing for the newer mapnik?

It was a bug in mod_tile. I've merged https://github.com/openstreetmap/mod_tile/pull/144 to fix it.
OK, I think the error is shown in the output. But here is the english version: ... /usr/local/include/mapnik/mapbox/variant.hpp:570:15: error: no type named ‘type’ in ‘struct std::enable_if<false, void>’ typename Enable = typename std::enable_ifTraits::is_valid::type> ^ ... This is the error message during compiling the mod_tile. You are right: f24 uses mapnik 3.0.10 and f25 3.0.12. I change the files in /usr/local/include/mapnik/mapbox/variant/ from f24 with the files in /usr/local/include/mapnik/mapbox/ from f25. That means that I compile with older files. Now, It works without error. That means: - the error is in the file from /usr/local/include/mapnik/mapbox/* in mapnik-devel 3.0.12 - I will close this bug.
