Question

I’m having a problem with CMake finding Boost headers (specifically thread).

In my CMakeLists.txt file… (non-Boost related script omitted for brevity)

… 
find_package(Boost COMPONENTS thread REQUIRED)

…

#this prints /Users/thomas/boost_1_47_0/boost
MESSAGE(${Boost_INCLUDE_DIR}) 

include_directories(${Boost_INCLUDE_DIR})

…

target_link_libraries(MY_PROG ${Boost_THREAD_LIBRARY})

CMake configures and generates makefiles fine, but I get this compile error:

error: boost/thread.hpp: No such file or directory

Thanks,
Dragonwrenn

P.S: Here’s the generated Makefile in case its useful

Answer 1

Since the error states error: boost/thread.hpp: No such file or directory, your Boost_INCLUDE_DIR should be changed from /Users/thomas/boost_1_47_0/boost to /Users/thomas/boost_1_47_0

That should solve the problem.
