How do I install these libraries? Why are they being required? Do I really need them?
Install these packages:
For X86_64 (64 bit):
pacman -S mingw-w64-x86_64-openssl mingw-w64-x86_64-zlib mingw-w64-x86_64-zstd
For X86 (32 bit):
pacman -S mingw-w64-i686-openssl mingw-w64-i686-zlib mingw-w64-i686-zstd

I'm trying to cross compiling ROS Melodic for aarch64 on raspberry pi 3 with toolchain that created by buildroot.
I followed the document http://wiki.ros.org/ROS/CrossCompiling/RaspberryPi/Cross-Compile%20ROS%20for%20the%20RaspberryPi, the source of ROS I try to build comes from:
rosinstall_generator ros_comm --rosdistro melodic --deps --tar > melodic-ros_comm.rosinstall
wstool init -j8 src melodic-ros_comm.rosinstall
And I got the error messages like these:

I guess the problem comes from boost?
The version of boost which I used is 1.65.1
All the steps I tried is contained in Dockerfile as link as below:

Thank you for your patience

I got another problem after changing the cmakelists

You should pass boost libraries to the target_link_libraries command. The smallest change to your file will be as follows:
target_link_libraries(qttest ${QT_LIBRARIES} ${LIBS})
But since you are using find_package for Boost and you do not actually use your LIBS variable anywhere, you should stick with something like this:
find_package(Boost COMPONENTS system REQUIRED)
...
target_link_libraries(qttest ${QT_LIBRARIES} ${OpenCV_LIBS} ${Boost_LIBRARIES})
And remove LIBS altogether.
I'm building a shared library in C++ that depends on dlib using CMake.
While it has been possible for me to build and install a shared dlib using make and make install, so far I haven't figured out the way to link to this shared dlib library.
The examples of usage given in the DLib website always link to a static library.
This is what I have so far:
cmake_minimum_required(VERSION 2.8.12)
project(face_align)
set(CMAKE_CXX_STANDARD 11)
find_package(dlib)
add_library(face_align SHARED src/mylib.cpp)
target_link_libraries(face_align dlib::dlib)
The linker complains like so:
/usr/bin/ld: cannot find -ldlib::dlib
collect2: error: ld returned 1 exit status
CMakeFiles/face_align.dir/build.make:94: recipe for target 'libface_align.so' failed
make[2]: *** [libface_align.so] Error 1
CMakeFiles/Makefile2:67: recipe for target 'CMakeFiles/face_align.dir/all' failed
make[1]: *** [CMakeFiles/face_align.dir/all] Error 2
Makefile:83: recipe for target 'all' failed
make: *** [all] Error 2
If I remove the SHARED from
add_library(face_align SHARED src/mylib.cpp) the project builds successfully. This makes me think that dlib:dlib is pointing to the static library. I see that there is a dlib:dlib_shared but no success linking to this one either.
The answer seems to be (1) linking to dlib as a static library (2) making the code linking to dlib position independent:
cmake_minimum_required(VERSION 2.8.12)
project(face_align)
set(CMAKE_CXX_STANDARD 11)
# Unfortunately, this only links dlib as static library
add_subdirectory(libs/dlib dlib_build)
add_library(face_align SHARED src/mylib.cpp)
# This makes the target position independent, allowing to link an static library to a dynamic one.
set_target_properties(face_align PROPERTIES POSITION_INDEPENDENT_CODE ON) # This made it work
# Link Dlib
target_link_libraries(face_align dlib::dlib)
EDIT:
Also, in Linux (I haven't tested this in other S.O.s) CMake does some magic and, after installing dlib library in shared mode:
$ cd $DLIB
$ mkdir build && cd build
$ cmake ../dlib
$ make && make install
Is possible to simply add the library using target_link_libraries as follows:
cmake_minimum_required(VERSION 2.8.12)
project(face_align)
set(CMAKE_CXX_STANDARD 11)
add_library(face_align SHARED src/mylib.cpp)
# Link Dlib
target_link_libraries(face_align dlib)
Then, in your code, include headers as follows:
#include <dlib/your_dlib_header_here.h>
I'm trying to link the jemalloc library into my application at build time using it as a generic implementation. According to https://github.com/jemalloc/jemalloc/wiki/Getting-Started the linking flags to use are:
-L`jemalloc-config --libdir` -Wl,-rpath,`jemalloc-config --libdir` -ljemalloc `jemalloc-config --libs`
So I did the following CMakeLists.txt:
cmake_minimum_required(VERSION 2.8.12.2)
project(widget)
include_directories(include)
file(GLOB SOURCES "src/*.cpp")
add_executable(widget ${SOURCES})
set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -L`jemalloc-config --libdir` -Wl,-rpath,`jemalloc-config --libdir` -ljemalloc `jemalloc-config --libs`")
But when I do make I get the following errors:
Linking CXX executable widget
c++: error: `jemalloc-config: No such file or directory
c++: error: unrecognized command line option ‘--libdir`’
c++: error: unrecognized command line option ‘--libdir`’
c++: error: unrecognized command line option ‘--libs`’
make[2]: *** [widget] Error 1
make[1]: *** [CMakeFiles/widget.dir/all] Error 2
For future generations, as this still comes up as one of the first links on Google.
Jemalloc comes with pkg-config setup, which can be used like this:
find_package(PkgConfig REQUIRED)
pkg_check_modules (JEMALLOC jemalloc)
pkg_search_module(JEMALLOC REQUIRED jemalloc)
include_directories(${JEMALLOC_INCLUDE_DIRS})
target_link_libraries(your_target_name ${JEMALLOC_LIBRARIES})
execute_process() command is your friend. Use it to run jemalloc-config executable and then put its output into CMake variables.
find you root_dir of jemalloc. Mine is /Users/lion/homebrew/Cellar/jemalloc/5.2.1_1/lib/
(I install jemalloc by brew on macOS)
link (soft link) all its lib to your local lib ln -s /Users/lion/homebrew/Cellar/jemalloc/5.2.1_1/lib/* /usr/local/lib
Then it works!
I see a lot of questions that are similar to this though not the same.
I'm having an issue getting boost recognized/working in Cmake using Clion I've tried a handful of ways including the incboost template included with Clion, moving on.
Cmake version 3.4
Boost version 1.60.0
find_package(Boost)
if (Boost_FOUND)
include_directories(${Boost_INCLUDE_DIR})
endif()
That's the auto generated incboost I mentioned above, This produces no results.
Second attempt is the following
set(Boost_Dir "C:\\Program Files (x86)\\boost_1_60_0\\")
find_package(Boost 1.60.0 COMPONENTS filesystem)
include_directories(${Boost_Dir})
CmakeFiles\Svp.dir/objects.a(main.cpp.obj):

And finally the solutions given here How do you add boost libraries in CMakeLists.txt have not changed my error output.
here's how I use it, in a portable way, in my projects:
if (WIN32)
set(BOOST_ROOT "C:/Program Files (x86)/boost_1_60_0/")
set(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_MULTITHREAD ON)
include_directories(${BOOST_ROOT})
link_directories(${BOOST_ROOT}/stage/lib) # add this before add_executable()
endif()
# Here call your add_executable method
# add_executable(TARGET_NAME ... )
if(NOT MSVC)
find_package(Boost REQUIRED COMPONENTS date_time filesystem wserialization system serialization thread regex)
if (Boost_FOUND)
include_directories(${Boost_INCLUDE_DIRS})
target_link_libraries(TARGET_NAME ${Boost_LIBRARIES})
endif()
endif()
You sometime need to specify the Boost_USE_STATIC_LIBS and Boost_USE_MULTITHREAD variables to help find_package find boost.
Also please specify the correct path to boost library with set(BOOST_ROOT, $path). Moreover, specify the boost packages you need in find_package. For instance
find_package(Boost REQUIRED COMPONENTS date_time filesystem thread regex)
if you only need the date_time filesystem thread regex packages
let me know if it works or not for you.
