CMake: Using Boost v1.69 with MSVC on Windows - c++

Question

I'm trying to use the Boost library in my C++ project on Windows using CLion and MinGWMSVC. I downloaded the precompiled binaries here and extracted everything to C:\local\boost_1_69_0_b1_rc3. I setup the following CMakeLists.txt:
cmake_minimum_required(VERSION 3.11.4)
project(BoostTesting)
set(CMAKE_CXX_STANDARD 17)
set(BOOST_ROOT "C:/local/boost_1_69_0_b1_rc3")
set(BOOST_LIBRARYDIR "C:/local/boost_1_69_0_b1_rc3/lib64-msvc-14.1")
set(BOOST_INCLUDEDIR "C:/local/boost_1_69_0_b1_rc3/boost")
set(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_MULTITHREADED ON)
set(Boost_USE_STATIC_RUNTIME OFF)
set(Boost_DEBUG ON)
set(Boost_DETAILED_FAILURE_MSG ON)
set(Boost_COMPILER "-vc141")
set(Boost_ARCHITECTURE "-x64")
find_package(Boost 1.69.0 COMPONENTS filesystem REQUIRED)
if (Boost_FOUND)
include_directories(${Boost_INCLUDE_DIRS})
add_executable(BoostTesting main.cpp)
target_link_libraries(BoostTesting ${Boost_LIBRARIES})
endif ()
Using CMake's FindBoost debug mode (Boost_DEBUG) I got the following output:

CMake is looking for those specific files but I noticed that the -x64 indication is not part of the searched file names. My directory only contains 64-bit libraries:
Why is the Boost_ARCHITECTURE environment variable ignored? I expect it to add the missing -x64 to the searched file names. If I manually rename the libboost_filesystem-vc141-mt*.lib files they can be found by CMake. However, if I compile and link my simple main.cpp I'm getting a linker error:

I'm pretty sure renaming the files is not the proper way of doing it. But even this way it doesn't work. What am I doing wrong and how do you properly use Boost in a simple C++ project like this one?

Answer 1

I believe find_package(Boost ...) has failed in your case as it won't be able to find the REQUIRED filesystem library for 64-bit GCC.
Make sure you have the GCC build of Boost available as well, because now you're only showing the V++ libraries.

Answer 2

You got CMake warning
New Boost version may have incorrect or missing dependencies and imported targets
because that CMake version does not prepared for boost 1.69 (Maybe latest CMake does...).
So CMake tries its best to recognize that version, so it still may work (see point 3 below).
#Felix Natter correctly pointed out above that Boost_ARCHITECTURE is handled only from CMake 3.13.
You can make it work without manual renaming, without GCC or MINGW, if you rebuild your boost with one of the file naming "layouts", your CMake recognizes.
(From your debug log these ones:
libboost_<module name>-<toolset>[-mt]-<ABI tag>-<boost version>
libboost_<module name>-<toolset>[-mt]-<ABI tag>
libboost_<module name>[-mt]-<ABI tag>-<boost version>
libboost_<module name>[-mt]
libboost_<module name>)
Unfortunately only the system layout matches, which means you need to separate Debug and Release builds in different "lib" folders. For explanation about the "layout" parameter see here.
So rebuild boost by specifying the --layout=system parameter, and also decide the variant by specifying variant=debug or variant=release.
As a starting point, on SF you can find the build log file:
https://sourceforge.net/projects/boost/files/boost-binaries/1.69.0/boost_1_69_0-64bitlog.txt/download
The last build "entry" in the file is for vc141, which is your version:
b2 -j%NUMBER_OF_PROCESSORS% --without-mpi --build-type=complete toolset=msvc-14.1 address-model=64 architecture=x86 --prefix=.\ --libdir=lib64-msvc-14.1 --includedir=garbage_headers install
Go to your boost source root and do > bootstrap first.
Make sure msvc-14.1 was detected.
Now build:
> b2 -a -j%NUMBER_OF_PROCESSORS% --without-mpi --with-filesystem toolset=msvc-14.1 address-model=64 architecture=x86 variant=debug --layout=system --prefix=C:\boost_build\debug
Do it for Release in a different target directory.
Change --prefix according to your needs. You may also specify --libdir and --includedir if the default is not good for you.
Of course, probably you need to modify your CMakeList file so that it can use both the Debug and Release variants...
So the best is to use a CMake version, which recognizes boost ver 1.69, and/or get a CMake-based version of boost, which includes 1.69.

Answer 3

set(Boost_ARCHITECTURE "-x64")
only works with cmake >= 3.13 [1] [2]. If you cannot upgrade to cmake 3.13+,
you can work around with:
set(CMAKE_CXX_COMPILER_ARCHITECTURE_ID, "x64")
(not sure under what conditions this is set automatically)

[2] https://cmake.org/cmake/help/v3.13/module/FindBoost.html

Answer 4

It turns out it works when using the MinGW distribution with built-in Boost.
CMakeLists.txt:
cmake_minimum_required(VERSION 3.11.4)
project(BoostTesting)
set(CMAKE_CXX_STANDARD 17)
if(WIN32)
set(BOOST_ROOT "C:/MinGW")
endif ()
find_package(Boost 1.67.0 COMPONENTS filesystem REQUIRED)
if (Boost_FOUND)
include_directories(${Boost_INCLUDE_DIRS})
add_executable(BoostTesting main.cpp)
target_link_libraries(BoostTesting ${Boost_LIBRARIES})
endif ()
main.cpp output:
D:\Cpp\BoostTesting\cmake-build-debug\BoostTesting.exe
Usage: tut1 path
Process finished with exit code 1
It compiled and linked successfully.
