Hello,
I'm trying to run a node from rosrun (it works when I manually enter ./program inside build directory). Yet it doesn't work when called by rosrun - it finds the directory by tab completion, but not the executable. How can I help it? I need it to use it in launch files.
[rosrun] Found the following, but they're either not files,
[rosrun] or not executable:
[rosrun] /home/user/ros_ws/catkin_ws/src/ros_programme
EDIT
The final solution to this was to make sure to call catkin_package() in the CMakeLists.txt, and to make sure to call it before any add_executable() or add_library() calls.
Original answer
Looking at your CMakeLists.txt, you've named your executables ros_aruco and subpose. The correct way to run them is with:
rosrun ros_programme ros_aruco
Or
rosrun ros_programme subpose
The relevant lines in your CMakeLists.txt that set these names are:
add_executable(ros_aruco src/ros_aruco.cpp)
add_executable(subpose src/subpose.cpp)
I would also expect the final binaries to be generated into devel/lib/ros_aruco rather than build/ros_aruco; are you passing any extra flags to catkin_make that might be changing this behavior?
I ran across the same error when trying to rosrun after doing a catkin_make install, it turned out I had the install TARGETS set to CATKIN_GLOBAL_BIN_DESTINATION instead of CATKIN_PACKAGE_BIN_DESTINATION (because I had copied that from somewhere else?), and the executables were going into install/bin rather than install/lib/my_package.
The correct answer to this problem is to add
set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/bin)
at the beginning of CMakeLists.txt.

did you run the setup script for your catkin workspace?
Yes. The problem lies in the location of the executables. They're in catkin_ws/build/package_name and they should be somewhere in devel/lib I think. I guess it's something with the CMake file inside package source, but no idea what exactly.
What is the exact command line of your rosrun? What is that package setup and ROS_PACKAGE_PATH?
rosrun ros_programme ros_programme - doesn't work ./ros_programme (build/ros_programme directory) works I'm not sure what you mean by package setup, I'm a little bit green here. After sourcing many things, this is the ROS_PACKAGE_PATH. /home/user/ros_ws/catkin_ws/install/share:/home/omikron/ros_ws/catkin_ws/install/stacks:/home/user/ros_ws/catkin_ws/src:/opt/ros/hydro/share:/opt/ros/hydro/stacks
Where is your code and "sourcing many things" would be the package setup. Is the binary in any of the paths in your package path? e.g. .../install
Additionally, the packages I put inside catkin_ws (downloaded from miscellaneous locations) usually allow me to easily use rosrun. This is the CMakeLists.txt of my package (also downloaded, but clearly somehow incomplete) http://pastebin.com/XNkxU93i
The binary is only in build directory (catkin_ws/build/ros_programme).
did you type ($source devel/setup.bash) in your catkin_ws before typing rosrun ...
