I'm building my c++ program with cmake on a Mac. The compiler gives me following Error:
error: boost/filesystem.hpp: No such file or directory
The line that triggers the error is the following:
#include "boost/filesystem.hpp"
or
#include <boost/filesystem.hpp>
Which of the above I use doesn't changed the Error
But in my CMakeLists.txt I include the boost headers in the following way:
FIND_PACKAGE(Boost)
MESSAGE("Boost information:")
MESSAGE(" Boost_INCLUDE_DIRS: ${Boost_INCLUDE_DIRS}")
MESSAGE(" Boost_LIBRARIES: ${Boost_LIBRARIES}")
MESSAGE(" Boost_LIBRARY_DIRS: ${Boost_LIBRARY_DIRS}")
INCLUDE_DIRECTORIES(${Boost_INCLUDE_DIRS})
LINK_DIRECTORIES(${Boost_LIBRARY_DIRS})
Boost include dirs is filled with "/opt/local/include/" during the cmake process and this folder contains a folder boost which contains the filesystem.hpp
Boost gives the following messages while generating the Makefile, I only copied the boost part:
-- Boost version: 1.38.0
-- Found the following Boost libraries:
Boost information:
Boost_INCLUDE_DIRS: /opt/local/include
Boost_LIBRARIES:
Boost_LIBRARY_DIRS: /opt/local/lib
-- Configuring done
While running make VERBOSE=1 This line contains the error:
cd /Users/janusz/Documents/workspace/ImageMarker/Debug/src && /usr/bin/c++ -O3 -Wall -Wno-deprecated -g -verbose -I/Users/janusz/Documents/workspace/ImageMarker/src/. -o CMakeFiles/ImageMarker.dir/FaceRecognizer.cpp.o -c /Users/janusz/Documents/workspace/ImageMarker/src/FaceRecognizer.cpp /Users/janusz/Documents/workspace/ImageMarker/src/FaceRecognizer.cpp:8:32: error: boost/filesystem.hpp: No such file or directory make[2]: *** [src/CMakeFiles/ImageMarker.dir/FaceRecognizer.cpp.o] Error 1
Do you understand why the compiler isn't picking the /opt/local/include directory?
If you need more information I'm happy to provide it
