I try to build my project with cmake. Evrything but boost work. For boost i get this message.
Boost version: 1.56.0
Boost include path: C:/Boost/include/boost-1_56
Could not find the following Boost libraries:
boost_program_options
No Boost libraries were found. You may need to set BOOST_LIBRARYDIR to the directory containing Boost libraries or BOOST_ROOT to the location of Boost.

Can someone tell me what I did wrong? I fixed the environment variable for boost as follows : C:\Boost.

I have installed the libboost-all-dev packaged on Ubuntu.
Cmake 3.10.2 can find boost but not "boost_core".
When I change the find package line to:
find_package(Boost REQUIRED COMPONENTS core)
Then it complains that it can't find "boost_core".
I actually just need boost/iterator...
How to make cmake find that?
Thanks.
CMakeLists.txt:
cmake_minimum_required(VERSION 3.10)
project(test_boost_iterator)
set(CMAKE_CXX_STANDARD 11)
find_package(Boost REQUIRED)

add_executable(test_boost_iterator main.cpp)

As I know there is no such a boost library core. You can check if a library should be linked here.
And Boost.Iterator is a header-only library, so you don't need to link anything. Just include <boost/iterator/...>. If you can't include, check whether these includes actually exist in your local boost distro.
I checked it for boost::counting_iterator<int> and all works well for me.
To reproduce my issue... I download Boost, then I run booststrap and b2 --build-dir=C:\Users\xxx\Downloads\my_boost_build_dir --prefix=C:\Users\xxx\Downloads\my_boost_install_dir --layout=system variant=release link=static install. Everything seems so far so good. The provided prefix (install) dir is populated with headers and libs.
But here's where things start going wrong. If I write the following cmake file...
find_package(Boost REQUIRED)
message("Boost_FOUND" ${Boost_FOUND})
message("Boost_INCLUDE_DIRS" ${Boost_INCLUDE_DIRS})
message("Boost_LIBRARY_DIRS" ${Boost_LIBRARY_DIRS})
message("Boost_LIBRARIES" ${Boost_LIBRARIES})
message("Boost_CHRONO_FOUND" ${Boost_CHRONO_FOUND})
message("Boost_CHRONO_LIBRARY" ${Boost_CHRONO_LIBRARY})
add_executable(main main.cpp)
target_link_libraries(main PRIVATE Boost::boost Boost::chrono)
...and I configure it with the path to the boost install dir cmake .. -DCMAKE_PREFIX_PATH=C:\Users\xxx\Downloads\my_boost_install_dir, then I get the following output and error...
Boost_FOUND1
Boost_INCLUDE_DIRSC:/Users/xxx/Downloads/my_boost_install_dir/include

-- Configuring done
CMake Error at CMakeLists.txt:14 (add_executable):
Target "main" links to target "Boost::chrono" but the target was not found.
Perhaps a find_package() call is missing for an IMPORTED target, or an
ALIAS target is missing?
Boost is found, the include and lib dirs are found, but the chrono library (and all other libraries) are not. Maybe I need to explicitly name my components? So I tried this cmake instead...
find_package(Boost REQUIRED COMPONENTS chrono)
message("Boost_FOUND" ${Boost_FOUND})
message("Boost_INCLUDE_DIRS" ${Boost_INCLUDE_DIRS})
message("Boost_LIBRARY_DIRS" ${Boost_LIBRARY_DIRS})

message("Boost_CHRONO_LIBRARY" ${Boost_CHRONO_LIBRARY})
add_executable(main main.cpp)
target_link_libraries(main PRIVATE Boost::boost Boost::chrono)
But this produces the following output and error.

Like before, it found boost and the headers, but for some reason it can't find the libraries.
If you want to use specific (non-header-only) Boost components, you have to specify them in find_package. In your case:
find_package(Boost COMPONENTS chrono REQUIRED)
According to https://cmake.org/cmake/help/v3.0/module/FindBoost.html
find_package(Boost) follow the hints below to find boost directories:
BOOST_ROOT - Preferred installation prefix (or BOOSTROOT)
BOOST_INCLUDEDIR - Preferred include directory e.g.
/include
BOOST_LIBRARYDIR - Preferred library directory e.g. /lib
Boost_NO_SYSTEM_PATHS - Set to ON to disable searching in locations
not
specified by these hint variables. Default is OFF.
Boost_ADDITIONAL_VERSIONS
- List of Boost versions not known to this module
(Boost install locations may contain the version)
If you don't know where is the default location to put your boost libraries and include files, you should set these variables before find_package.
The root directory of boost ($ENV{BOOST_ROOT}) is
C:\Boost\boost_1_64_0
All compiled libraries (.dll, .lib) are in
C:\Boost\boost_1_64_0\lib64-msvc-14.1
They have both boost_xxx and libboost_xxx.
My cmake file is
set(BOOST_ROOT "$ENV{BOOST_ROOT}")
set(BOOST_LIBRARYDIR "$ENV{BOOST_ROOT}/lib64-msvc-14.1")
message("${BOOST_ROOT}")
message("${BOOST_LIBRARYDIR}")
message("${Boost_INCLUDE_DIR}")
if(MSVC)
add_definitions(-DBOOST_ALL_NO_LIB)
add_definitions(-DBOOST_ALL_DYN_LINK)
endif()
find_package(Boost 1.64.0 COMPONENTS system filesystem program_options REQUIRED)
And the output is
C:\Boost\boost_1_64_0
C:\Boost\boost_1_64_0/lib64-msvc-14.1
C:/Boost/boost_1_64_0

Could someone help please? I have spent hours on this but couldn't figure out why this doesn't work.
First of all, what CMake version do you use? Recently a regression fix was included into 3.8.1 release -- it was about backslashes in BOOST_ROOT.
Secondly, you don't need to specify anything else ('cept maybe the BOOST_ROOT) if you are using official prebuilt Windows binaries -- FindBoost.cmake would try to find them as well. (Unfortunately I can't recall since what version.)
Never do set(BOOST_ROOT...) in your CMakeLists.txt -- just pass this parameter to cmake run via -D option. A better way is the following:
if(NOT DEFINED BOOST_ROOT AND NOT "${ENV{BOOST_ROOT}" STREQUAL "")
set(BOOST_ROOT "$ENV{BOOST_ROOT}")
endif()
Use imported targets to link w/ needed Boost libraries and to modify compile/linker flags per taget. Please avoid to modify "global" compiler/linker options -- i.e. use corresponding target_xxx commands instead of add_definitions & etc.
I use the following script to load boost with CMake (working with Linux and Windows) :
set(BoostPath "${DefaultBoostPath}" CACHE PATH "Path to Boost")
message(STATUS "Path to Boost: ${BoostPath}")
set(BOOST_ROOT "${BoostPath}")
set(Boost_USE_MULTITHREAD ON)
set(Boost_USE_STATIC_LIBS ON)
set(Boost_NO_SYSTEM_PATHS ON)
set(Boost_ADDITIONAL_VERSIONS "1.57.0" "1.57" "1.58.0" "1.58" "1.59.0" "1.59" "1.60.0" "1.60" "1.61.0" "1.61" "1.62.0" "1.62" "1.63.0" "1.63" "1.64.0" "1.64")
find_package(Boost ${RequiredBoostVersion} REQUIRED COMPONENTS ${RequiredBoostComponents})
mark_as_advanced(FORCE Boost_DIR)
set(BoostVersion "${Boost_MAJOR_VERSION}.${Boost_MINOR_VERSION}.${Boost_SUBMINOR_VERSION}")
message(STATUS "Boost version: ${BoostVersion}")
if(CompilerName STREQUAL "gcc")
set(System_LIBRARIES ${System_LIBRARIES} pthread rt)
endif()
You can see I have to add some versions of Boost because my version of CMake doesn't know last versions.
What's your CMake version ? Maybe it's the same problem.
Where are your headers? I don't think it found the include directory (which is necessary for this to be successful).
Search for FindBoost.cmake in your cmake installation directory, there are lots of useful things in there for troubleshooting.
using set(Boost_DEBUG ON) can help you figure out which paths are searched and what the filenames of the libraries are searched. You can specify the include directory (directory where folder boost is stored) with set(Boost_INCLUDEDIRS ${BOOST_ROOT}/inc), though what I just showed is one of the places that FindBoost.cmake searches.
Also, you don't need set(BOOST_ROOT "$ENV{BOOST_ROOT}"). FindBoost.cmake does that for you if you don't set ${BOOST_ROOT}.
Note that if you just downloaded boost, extracted the archive to ${BOOST_ROOT} and compiled with b2, then all of your files are in ${BOOST_ROOT}/stage. This is also a good place for them to reside. If you manually copy files somewhere else, then FindBoost may have some troubles finding them.
I am not able to figure out why am I getting this error.

It says, Unable to find requested boost library. But I have installed boost 1.48.0 and build it using Visual studio console, and have passed BOOST_LIBRARYDIR=D:/Shark/boost_1_48_0/stage/lib and BOOST_ROOT=D:/Shark/boost_1_48_0.
CMake's FindBoost macros look for the libs in various spots based on the compiler your using. Even if you specify BOOST_LIBRARYDIR, you still have to conform to the standards the FindBoost macro expects for filenames ie:
${Boost_LIB_PREFIX}boost_${COMPONENT}${_boost_COMPILER}${_boost_MULTITHREADED}${_boost_RELEASE_ABI_TAG}-${Boost_LIB_VERSION}
${Boost_LIB_PREFIX}boost_${COMPONENT}${_boost_COMPILER}${_boost_MULTITHREADED}${_boost_RELEASE_ABI_TAG}
${Boost_LIB_PREFIX}boost_${COMPONENT}${_boost_MULTITHREADED}${_boost_RELEASE_ABI_TAG}-${Boost_LIB_VERSION}
${Boost_LIB_PREFIX}boost_${COMPONENT}${_boost_MULTITHREADED}${_boost_RELEASE_ABI_TAG}
${Boost_LIB_PREFIX}boost_${COMPONENT} )
Example filenames matching this template for visual studio 2013 (aka msvc 12)
$BOOST_LIBRARY_DIR/boost_atomic-vc120-mt-1_58.dll
$BOOST_LIBRARY_DIR/boost_atomic-vc120-mt-gd-1_58.dll
You'll note that the mt for multithreaded build and the gd to indicate it's a debug build. FindBoost is fussy and will look for the debug build if your CMake project has a CMAKE_BUILD_TYPE=Debug
Additionally if your building multithreaded you'll need to define:
Boost_USE_MULTITHREADED=ON
If your still having trouble you define: Boost_DEBUG=1 and you'll see a lot of additional output about how and where FindBoost is searching.
I was building the boost library by downloading source file. The problem was it was not creating .dll (only .lib).
I downloaded boost binary and installed it from installer to get those files, and set the path BOOL_LIBRARYDIR=C:/local/boost/lib64-msvc-14.0 and BOOL_ROOT=C:/local/boost to make it done.
I'm trying compile tibia server with CMake 3.1.3 but I'm getting the following error:
