When configuring, the logs show the following in red, I've included version and OS if it helps.
Windows 10
CMake 3.25.1
Boost 1.81.0
Visual Studio 17 2022

Boost_DIR = Boost_DIR-NOTFOUND
Boost_FILESYSTEM_LIBRARY_DEBUG = Directory is correct
...
Boost_SYSTEM_LIBRARY_RELEASE = Directory is correct
Just to be on the safe side, I added "BOOST_ROOT" and the directory to both "User variables" and S"ystem variables".
Now, I've already used the bootstrap.bat, followed by the b2.exe. CMake shows the directory for everything else except the BOOST_DIR. When I click on configure, it still shows these errors.

If you get an error that CMake *Could NOT find Boost (missing: system filesystem program_options iostreams regex) (found suitable version "1.74.0", minimum required is "1.70")
Locate your Boost folder
Run the Bootstrap.bat file
Run the b2.exe file
You can try a diffrent version of boost like latest one 1.81
https://netix.dl.sourceforge.net/project/boost/boost-binaries/1.81.0/boost_1_81_0-msvc-14.3-64.exe
i'm useing this version
don't forget you must edit system variables for this version directory
and don't forget you must use slash / for directory not back slash \ like this:
orginal location: C:\local\boost_1_81_0
on system variables: C:/local/boost_1_81_0

I am trying to build some code using cmake. The code uses some Boost libraries. Because of that I try to find Boost in the cmakefile:
find_package(Boost 1.65.1 REQUIRED COMPONENTS unit_test_framework program_options )
I have installed boost version 1.58 via apt (I am using Linux Mint 18.3), so I obviously get the error message when trying to cmake the code:
CMake Error at /usr/share/cmake-3.5/Modules/FindBoost.cmake:1677 (message):
Unable to find the requested Boost libraries.
Boost version: 1.58.0
Boost include path: /usr/include
Detected version of Boost is too old. Requested version was 1.65.1 (or newer).
Call Stack (most recent call first):
CMakeLists.txt:14 (find_package)
-- Configuring incomplete, errors occurred!
So I went on and downloaded Boost 1.65.1 by source and built it the intended way and installed it with the prefix
sudo ./b2 install --prefix=/usr/include
When I try to build the code again, it still gives the exact same error message as before, stating that it didn't find the newer version. I have tried to uninstall version 1.58 and build, but then cmake doesn't find Boost at all.
How can I install Boost in a way, that cmake is able to find it?
Thanks in advance,
cheers!
When changing the version information of Boost in a find_package(Boost) call you need to clear the CMakeCache.txt file. Otherwise the cached information from the previous run is used.
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)
include_directories(${Boost_INCLUDE_DIR})
add_definitions( "-DHAS_BOOST" )
add_executable(test_boost_iterator main.cpp)
Success message (before replacing the find_package line):
-- Boost version: 1.65.1
-- Configuring done
-- Generating done
Error message (after replacing the find_package line)
Unable to find the requested Boost libraries.
Boost version: 1.65.1

Could not find the following Boost libraries:
boost_core
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.
Call Stack (most recent call first):
CMakeLists.txt:6 (find_package)
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.
I have been facing some problems when trying to configure a project with CMake.
Even though CMake seems to find the needed libs:
Boost version: 1.49.0
Found the following Boost libraries:
system
thread
chrono
It still can't find its root directory:
Boost_DIR-NOTFOUND
I'm using Linux Mint 15 (Olivia). Thanks in advance.
If you want to check whether the search was successful, you need to check the variable Boost_FOUND instead.
find_package(Boost [...])
if(NOT Boost_FOUND)
message(FATAL_ERROR "Could not find boost!")
endif()
The Boost_DIR variable is only of significance when using Boost's package configuration file (which is currently no longer supported as of Boost 1.54). It is therefore perfectly fine if this value is left in the NOTFOUND state by the find call.
See the documentation for details.
I'm trying to configure a project using CMake, but it fails to find Boost libraries even though they are in the specified folder. I have specified Boost_INCLUDE_DIR, Boost_LIBRARYDIR and BOOST_ROOT , but I still get an error saying that CMake is not able to find Boost. What could be the reason of such error?
Are you sure you are doing it the correct way? The idea is that CMake sets BOOST_INCLUDE_DIR, BOOST_LIBRARYDIR and BOOST_ROOT automatically. Do something like this in CMakeLists.txt:
FIND_PACKAGE(Boost)
IF (Boost_FOUND)
INCLUDE_DIRECTORIES(${Boost_INCLUDE_DIR})
ADD_DEFINITIONS( "-DHAS_BOOST" )
ENDIF()
If boost is not installed in a default location and can, thus, not be found by CMake, you can tell CMake where to look for boost like this:
SET(CMAKE_INCLUDE_PATH ${CMAKE_INCLUDE_PATH} "C:/win32libs/boost")
SET(CMAKE_LIBRARY_PATH ${CMAKE_LIBRARY_PATH} "C:/win32libs/boost/lib")
Of course, those two lines have to be before the FIND_PACKAGE(Boost) in CMakeLists.txt.
There is more help available by reading the FindBoost.cmake file itself. It is located in your 'Modules' directory.
A good start is to set(Boost_DEBUG 1) - this will spit out a good deal of information about where boost is looking, what it's looking for, and may help explain why it can't find it.
It can also help you to figure out if it is picking up on your BOOST_ROOT properly.
FindBoost.cmake also sometimes has problems if the exact version of boost is not listed in the Available Versions variables. You can find more about this by reading FindBoost.cmake.
Lastly, FindBoost.cmake has had some bugs in the past. One thing you might try is to take a newer version of FindBoost.cmake out of the latest version of CMake, and stick it into your project folder alongside CMakeLists.txt - then even if you have an old version of boost, it will use the new version of FindBoost.cmake that is in your project's folder.
Good luck.
For me this error was simply because boost wasn't installed so on ubuntu:
sudo apt install build-essential libboost-system-dev libboost-thread-dev libboost-program-options-dev libboost-test-dev
I struggled with this problem for a while myself. It turned out that cmake was looking for Boost library files using Boost's naming convention, in which the library name is a function of the compiler version used to build it. Our Boost libraries were built using GCC 4.9.1, and that compiler version was in fact present on our system; however, GCC 4.4.7 also happened to be installed. As it happens, cmake's FindBoost.cmake script was auto-detecting the GCC 4.4.7 installation instead of the GCC 4.9.1 one, and thus was looking for Boost library files with "gcc44" in the file names, rather than "gcc49".
The simple fix was to force cmake to assume that GCC 4.9 was present, by setting Boost_COMPILER to "-gcc49" in CMakeLists.txt. With this change, FindBoost.cmake looked for, and found, my Boost library files.
You can also specify the version of Boost that you would like CMake to use by passing -DBOOST_INCLUDEDIR or -DBOOST_ROOT pointing to the location of correct version boost headers
Example:
cmake -DBOOST_ROOT=/opt/latestboost
This will also be useful when multiple boost versions are on the same system.
I also had a similar problem and discovered that the BOOST_INCLUDE_DIR, BOOST_LIBRARYDIR and BOOST_ROOT env variables must hold absolute paths.
HTH!
In my case Boost was not installed. I used below command on Mac and then cmake find_package(Boost) works like a charm
brew install Boost
Please note upper case 'B' in Boost!
If you are building your own boost do not forget to use the --layout=versioned otherwise the search for a particular version of library will fail
For cmake version 3.1.0-rc2 to pick up boost 1.57 specify -D_boost_TEST_VERSIONS=1.57
cmake version 3.1.0-rc2 defaults to boost<=1.56.0 as is seen using -DBoost_DEBUG=ON
cmake -D_boost_TEST_VERSIONS=1.57 -DBoost_DEBUG=ON -DCMAKE_BUILD_TYPE=Debug -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++
One more bit of advice for anyone trying to build CGAL in particular, with statically linked Boost. It is not enough to define Boost_USE_STATIC_LIBS; it gets overridden by the time Boost_DEBUG outputs its value. The thing to do here is to check the "Advanced" checkbox and to enable CGAL_Boost_USE_STATIC_LIBS.
I had the same problem while trying to run make for a project after installing Boost version 1.66.0 on Ubuntu Trusty64. The error message was similar to (not exactly like) this one:
CMake Error at
/usr/local/Cellar/cmake/3.3.2/share/cmake/Modules/FindBoost.cmake:1245 (message):

Boost was definitely installed, but CMake couldn't detect it. After spending plenty of time tinkering with paths and environmental variables, I eventually ended up checking cmake itself for options and found the following:
--check-system-vars = Find problems with variable usage in system files
So I ran the following in the directory at issue:
sudo cmake --check-system-vars
which returned:
Also check system files when warning about unused and uninitialized variables.
-- Boost version: 1.66.0
-- Found the following Boost libraries:

-- date_time
-- chrono

-- Configuring done

-- Build files have been written to: /home/user/myproject
and resolved the issue.
See FindBoost.cmake first. The variables you set are the correct ones but they should be all uppercase.
Make sure the library architecture matches with CMake configuration.
cmake -A x64 ..
I suggest creating a minimal executable which only includes a Boost library to see if it compiles.
#include <iostream>
#include <boost/date_time.hpp>
int main() {
using namespace std;
using namespace boost::gregorian;
date today = day_clock::local_day();
cout << today << endl;
}
find_package(Boost REQUIRED COMPONENTS
date_time
)
include_directories(${Boost_INCLUDE_DIR})
link_directories(${Boost_LIBRARY_DIRS})
add_executable(test_boost "test_boost.cpp")
target_link_libraries(test_boost Boost::date_time)
Start debugging by checking Boost_FOUND first.
message(STATUS "Boost_FOUND: ${Boost_FOUND}")
The version should be found even if no libraries are found. (Boost_VERSION)
If Boost_LIBRARY_DIRS becomes non-empty, it should compile.
I had the same problem, and none of the above solutions worked. Actually, the file include/boost/version.hpp could not be read (by the cmake script launched by jenkins).
I had to manually change the permission of the (boost) library (even though jenkins belongs to the group, but that is another problem linked to jenkins that I could not figure out):
chmod o+wx ${BOOST_ROOT} -R # allow reading/execution on the whole library
#chmod g+wx ${BOOST_ROOT} -R # this did not suffice, strangely, but it is another story I guess
This can also happen if CMAKE_FIND_ROOT_PATH is set as different from BOOST_ROOT.
I faced the same issue that in spite of setting BOOST_ROOT, I was getting the error.
But for cross compiling for ARM I was using Toolchain-android.cmake in which I had (for some reason):
set(BOOST_ROOT "/home/.../boost")
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} --sysroot=${SYSROOT}")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} --sysroot=${SYSROOT} -I${SYSROOT}/include/libcxx")
set(CMAKE_CXX_LINK_FLAGS "${CMAKE_CXX_LINK_FLAGS}")
set(CMAKE_FIND_ROOT_PATH "${SYSROOT}")
CMAKE_FIND_ROOT_PATH seems to be overriding BOOST_ROOT which was causing the issue.
For those using python3.7 docker image, this solved:
apt install libboost-system-dev libboost-thread-dev
Maybe
brew install boost
will help you.
