Created attachment 459758 [details] fixed ebuild
Since many ROS packages are affected by this problem, I think it should actually be fixed in ros-catkin.eclass. So I did this: --- /usr/portage/eclass/ros-catkin.eclass 2016-05-11 10:45:28.000000000 +0200 +++ ros-catkin.eclass 2017-01-12 17:31:55.469531376 +0100 @@ -184,6 +184,7 @@ "$(cmake-utils_use test CATKIN_ENABLE_TESTING)" "-DCATKIN_BUILD_BINARY_PACKAGE=ON" "-DCATKIN_PREFIX_PATH=${SYSROOT:-${EROOT}}/usr" + "-DCMAKE_CXX_FLAGS_INIT=-std=c++11" "${mycatkincmakeargs[@]}" ) if [ -n "${CATKIN_DO_PYTHON_MULTIBUILD}" ] ; then
Turns out that dev-ros/collada_parser uses typeof() operator, so we might want to use -std=gnu++11 instead.
commit c0e7c659072809089e00cf1ce582cea58158dcb2 Author: Alexis Ballier <aballier@gentoo.org> Date: Sat Jan 28 16:26:36 2017 +0100 eclass/ros-catkin.eclass: Build all ROS packages in C++11 mode. Some of them require it, all dev-ros category should have been fixed to build in C++11 mode now. Suggested by Victor Mataré in bug #605466, fixing all its dupes too. Some packages failed to build in C++11 mode but should have been fixed. Those that require C++14/gnu++11 or whatever can still override the default in src_configure.
