My Problem is that CMake is refusing to compile giving the following error:
[orpheus@Poseidon build]$ make sources : /home/orpheus/Projects/Personal/C++/test/testProj/src/helloworld/MyClass.cpp/home/orpheus/Projects/Personal/C++/test/testProj/src/helloworld.cpp headers : /home/orpheus/Projects/Personal/C++/test/testProj/include/helloworld/MyClass.hpp -- Configuring done -- Generating done -- Build files have been written to: /home/orpheus/Projects/Personal/C++/test/build [ 33%] Building CXX object CMakeFiles/TEST.dir/testProj/src/helloworld/MyClass.cpp.o /home/orpheus/Projects/Personal/C++/test/testProj/src/helloworld/MyClass.cpp:1:51: fatal error: testProj/include/helloworld/MyClass.hpp: No such file or directory #include "testProj/include/helloworld/MyClass.hpp" ^ compilation terminated. make[2]: *** [CMakeFiles/TEST.dir/build.make:63: CMakeFiles/TEST.dir/testProj/src/helloworld/MyClass.cpp.o] Error 1 make[1]: *** [CMakeFiles/Makefile2:68: CMakeFiles/TEST.dir/all] Error 2 make: *** [Makefile:84: all] Error 2 I am relatively new to CMake and have gone through most of the tutorials I can find as well as all the relevant stack overflow questions I could find, however nothing quite seems to cover my particular needs, I did (in my tweaking) stumble across a way where this didnt happen(unfortunately I cant replicate this now), however that gave me a linking error claiming:
c++; fatal error: no input files should I use the include_directory() command rather than set() to add the header files?
I decided on not using the glob() method of adding sources as per the CMake documentation and have based my solution off of this thread and a variety of tutorials.
I have the following project structure:
test/ | +--CMakeLists.txt +--build/ | |----CMakeFiles/ | |----etc | +--testProj/ | +----CMakeLists.txt | +----include | | +----CMakeLists.txt | | +----helloworld/ | | | +----CMakeLists.txt | | | +----MyClass.hpp | | | |----src | | +----helloworld.cpp | | +----CMakeLists.txt | | +----helloworld/ | | | +----CMakeLists.txt | | | +----MyClass.cpp files are as follows:
test/CMakeFiles.txt
cmake_minimum_required(VERSION 3.6.1) project(TEST) add_subdirectory(testProj) add_executable(${CMAKE_PROJECT_NAME} ${sources} ${headers}) set_target_properties(${CMAKE_PROJECT_NAME} PROPERTIES LINKER_LANGUAGE CXX) set(extraFlags "-Wall -Wextra -Weffc++ -pedantic -pedantic-errors -std=c++14") set(CMAKE_CXX_FLAGS ${CMAKE_CXX_FLAGS} ${extraFlags}) test/testProj/CMakeLists.txt

add_subdirectory(helloworld) set( sources ${sources} ${CMAKE_CURRENT_SOURCE_DIR}/helloworld.cpp PARENT_SCOPE ) test/testProj/src/helloworld/CMakeLists.txt
set( sources ${sources} ${CMAKE_CURRENT_SOURCE_DIR}/MyClass.cpp PARENT_SCOPE ) please can someone point me in the right direction as i'm about to put my head through the monitor.
