Dynamic linking of QT in WSL not working but working in docker container

Question

I want to build a c++ program that dynamically links the QT-Core library.

For this I am using the WSL as my build environment and CLion as my IDE. When I compile this programm in the WSL (ubuntu_18.04) the linker does not find the QtLibrary but when I compile it in a docker container (ubuntu_18.04) the linker finds the library.

I am quite confused by this since it seems to me I have set the library search path correctly. Anyone got any idea what might be causing this ?

My project structure is the following:

apps
- CMakeLists.txt
- main.cpp
extern
- qt-linux
src
- CMakeLists.txt
- functions.cpp
- functions.hpp
toolschains
- linux-toolchain.cmake
CMakeLists.txt
build.sh

The CMakeLists.txt files look like this:

CMakeLists.txt: cmake_minimum_required(VERSION 3.10) project(cpp_hello_world)

set(CMAKE_CXX_STANDARD 14)
set(CMAKE_INSTALL_PREFIX ${CMAKE_CURRENT_SOURCE_DIR}/Install)
set(CMAKE_SKIP_BUILD_RPATH  FALSE)
set(CMAKE_BUILD_WITH_INSTALL_RPATH FALSE)
set(CMAKE_INSTALL_RPATH "$ORIGIN/../lib")


# QT SETUP
if(UNIX)
    set(Qt5Core_DIR "extern/qt-linux/lib/cmake/Qt5Core")
    install(DIRECTORY ${PROJECT_SOURCE_DIR}/extern/qt-linux/lib/ DESTINATION 
    lib)
endif()
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTOUIC ON)
find_package(Qt5Core)

add_subdirectory(src)
add_subdirectory(apps)

src/CMakeLists.txt:

set(CMAKE_INCLUDE_CURRENT_DIR ON)

add_library(HelloLibrary SHARED functions.hpp functions.cpp)
target_link_libraries(HelloLibrary Qt5::Core)
target_include_directories(HelloLibrary PUBLIC ${CMAKE_CURRENT_SOURCE_DIR})


install(TARGETS HelloLibrary DESTINATION lib)
install(FILES functions.hpp DESTINATION include)

apps/CMakeLists.txt:

add_executable(hello-world main.cpp)

target_link_libraries(hello-world HelloLibrary)
target_link_libraries(hello-world -static-libgcc -static-libstdc++)
install(TARGETS hello-world DESTINATION bin)

and I build using the following build.sh script:

#!/bin/bash

export SOURCE_DIR=$(pwd)
rm -R build
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=../toolchains/linux- 
    toolchain.cmake -G "CodeBlocks - Unix Makefiles" ${SOURCE_DIR}

make
make install

Answer 1

I figured this one out now The problem was the libQt5Core.so.5 was build with .note.ABI-tag set to a version incompatible with what the WSL identifies as(4.4) but the docker container was compatible(4.9).

Similar to what happens here: https://github.com/Microsoft/WSL/issues/3023
