Cannot find library header files when cross compiling

william · June 24, 2022, 3:03pm

I’m cross compiling for arm on Arch Linux host, but the cross compiler cannot find any library headers.
CMakeLists.txt

cmake_minimum_required(VERSION 3.13)
project(cross-compile-demo C)

find_package(LibArchive REQUIRED)

add_executable(demo main.c)
target_link_libraries(demo ${LibArchive_LIBRARIES})

main.c

#include <stdio.h>
#include <archive.h>

int main(int argc, char const *argv[])
{
	return 0;
}

rpi4-toolchain.cmake

set(CMAKE_SYSTEM_NAME Linux)

set(CMAKE_C_COMPILER aarch64-linux-gnu-gcc)

set(CMAKE_CXX_COMPILER aarch64-linux-gnu-g++)
set(CMAKE_FIND_ROOT_PATH /usr/aarch64-linux-gnu /tmp/rpi-root)

set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)

What might be the issue?

TL;DR; use target_link_libraries(demo PRIVATE LibArchive::LibArchive)

Currently you’re linking using pure file paths, which do not carry any information about the include directories. While you could add target_link_libraries(demo PRIVATE ${LibArchive_INCLUDE_DIRS}) in modern CMake you should use imported targets that carry all the needed properties with them.

Thanks, the header files can be found now, however, it seems the ld program cannot find symbols now

Your toolchain file may need to add -rpath-link flags to help the linker find the libraries it needs.
