2016-10-20 11:11:10 -0500	commented question	avcodec.h -- no such file (Fedora 24) I think if you had both QT4 and QT5 installed, one would expect `/usr/bin/qmake` to correspond to version 4.

2016-06-30 14:28:48 -0500	answered a question	kinetic source install on Fedora23 As a partial answer, you need to get PySide through the package manager: `sudo dnf install pyside-tools python-pyside python-pyside-devel python2-pyudev-pyside` See the full list of what I had to install here: http://answers.ros.org/question/23800...

2016-06-30 11:37:30 -0500	answered a question	geometric_shapes package error, assimp/aiScene.h not found geometric_shapes detects ASSIMP incorrectly, but several other projects do it correctly. You can force the detection to work right by doing by including this on the catkin_make command: `-DASSIMP_UNIFIED_HEADER_NAMES=ON` . Mine looked like this: `./src/catkin/bin/catkin_make_isolated --install -DCMAKE_BUILD_TYPE=Release -DASSIMP_UNIFIED_HEADER_NAMES=ON`
2016-06-30 11:33:31 -0500	answered a question	Source compile of Kinetic on Fedora24 When I set up Fedora 24 recently, I had the same problem. See the notes here: http://answers.ros.org/question/23800... I did openCV 3.1 straight from Github because the catkin auto-dep wouldn't compile. Install Eigen/dev and TBB/dev first. Use the git clone and then go to that folder and run this: cmake -D WITH_TBB=ON -D WITH_EIGEN=ON -D CMAKE_BUILD_TYPE=RELEASE -D BUILD_TESTS=OFF -D BUILD_PERF_TESTS=OFF BUILD_EXAMPLES=OFF .. make && make install That bit me later when I had to do this for RViz and gazebo: sudo ldconfig /usr/local/lib64 /usr/local/lib and excluded it from Catkin's pull like this: rosinstall_generator desktop --rosdistro kinetic --deps --wet-only --tar --exclude opencv3 > kinetic-desktop-wet.rosinstall
2016-06-30 11:29:12 -0500	commented answer	source install + opencv source install Yes, this is something to understand when compiling on Fedora. Unless you manually specify a lib prefix when calling `configure/cmake`, the result will go to `/usr/local/lib` or `/usr/local/lib64`. You need to add both of those the lib search path using `ldconfig`, i.e. `sudo ldconfig path1 path2`
2016-06-30 11:24:53 -0500	answered a question	avcodec.h -- no such file (Fedora 24) As suggested in the comment, I proceeded to modify all the `CMakeLists.txt` in the `gazebo_ros_pkgs`. The modification was to add `/usr/include/ffmpeg` to the `include_directories` list. After that `gazebo_ros_pkgs` compiled fine. Alas, they don't run right on Fedora 24 even after that. They continue to look for Gazebo in the wrong location.

2016-06-24 12:31:53 -0500	asked a question	avcodec.h -- no such file (Fedora 24) I've spent the last few days getting my ROS stack to compile on Fedora 24. It has been quite a process. I'm almost there; I have 196 out of 197 projects compiling. I have one project that won't compile: gazebo_ros. It gives this error: `fatal error: libavcodec/avcodec.h: No such file or directory` However, the file clearly exists as a locate call shows it here: `/usr/include/ffmpeg/libavcodec/avcodec.h` I'm building the package like this: `catkin_make_isolated --force-cmake --pkg gazebo_ros -DCMAKE_BUILD_TYPE=Release` I attempted to add --make-args -I /usr/include/ffmpeg but the error persists. What can I do to resolve this error? Thanks for your time. For those others attempting to run ROS on Fedora 24, here are my notes: I had to use Fedora 24 because Ubuntu 15.10, 16.04, and 16.10 beta all failed to handle the graphics driver properly on a new MacPro with Radeon HD 7870 cards. I tried fglrx (latest) in 15.10 with no success either. Fedora has basic catkin packages included: sudo dnf install rospack rospack-devel python3-rosdep python3-rosinstall python3-rospkg python3-rosdistro catkin catkin-devel I had to install these additional packages (using sudo dnf install) before the catkin_make_isolated would succeed: freetype-freeworld cabextract xorg-x11-font-utils fontconfig curl curl-devel unzip git cmake pkg-config opencl-headers opencl-utils opencl-utils-devel libusb libusb-devel libjpeg-turbo libjpeg-turbo-devel doxygen opencl-utils clinfo mesa-libOpenCL-devel eigen3-devel gdal-devel gtest gtest-devel protobuf protobuf-c-devel protobuf-devel libdc1394 libdc1394-devel tesseract tinyxml tinyxml-devel ffmpeg ffmpeg-devel libstdc++ libstdc++-devel libstdc++-static libpng-devel jasper-devel openexr-devel libtiff-devel libwebp-devel libv4l-devel tbb-devel python-sphinx lapack lapack-devel libgphoto2-devel python-nose python-devel libudev libudev-dev orocos-kdl orocos-kdl-devel python-rosdep python-rosinstall_generator python-wstool python-rosinstall python-empy console-bridge console-bridge-devel extra-cmake-modules cmake-gui poco poco-devel boost boost-random boost-static boost-system boost-thread boost-timer sip sip-devel python3-sip python3-sip-devel pyside-tools python-pyside python-pyside-devel python2-pyudev-pyside python-qt5 python-qt5-devel redhat-rpm-config lz4 lz4-devel lzma lzma-devel urdfdom urdfdom-devel urdfdom-headers-devel qhull qhull-devel assimp assimp-devel collada-dom collada-dom-devel python2-numpy python2-numpy-f2py python3-numpy python3-numpy-f2py ogre ogre-devel libyaml libyaml-devel yaml-cpp yaml-cpp-devel yaml-cpp03 yaml-cpp03-devel python-netifaces python3-netifaces python2-defusedxml python3-defusedxml I was also working on kinect2 at the same time so some of those projects may apply to that.
