이 글은 conan new cmake_lib 을 사용하여 C++ 라이브러리 프로젝트를 만드는 방법을 소개합니다.

c++ 빌드 (feat. conan, cmake)

executable project - hello

먼저 conan new cmake_exe 를 사용하여 라이브러리를 사용할 hello 프로젝트를 만듭니다.

$ mkdir conan_cmake_lib
$ cd conan_cmake_lib
$ conan new cmake_exe -d name=hello -d version=1.0
File saved: CMakeLists.txt
File saved: conanfile.py 
File saved: src/hello.cpp
File saved: src/hello.h  
File saved: src/main.cpp 
File saved: test_package/conanfile.py

conan install 을 실행하여 의존성을 설치합니다. 사실 의존성이 없어서 설치되는 패키지는 없습니다.

$ conan install .

만약 cmake 로 빌드를 원한다면 configure 를 진행해야 합니다.

cmake --preset conan-default
cmake build .

build 디렉토리에 빌드된 실행파일을 실행해봅니다.

$ ./build/Debug/hello.exe 
hello/1.0: Hello World Debug!
  hello/1.0: _M_X64 defined

library project - format

이제 conan new cmake_lib 을 사용하여 format 라이브러리를 생성합니다.

$ mkdir -p libs/format
$ cd libs/format
$ conan new cmake_lib -d name=format -d version=1.0
File saved: CMakeLists.txt

File saved: include/format.h
File saved: src/format.cpp
File saved: test_package/CMakeLists.txt
File saved: test_package/conanfile.py
File saved: test_package/src/example.cpp

format 라이브러리는 fmt 라이브러리를 의존성으로 사용합니다. conanfile.py 파일에 requirements 를 추가하여 fmt 라이브러리를 의존성으로 추가합니다.

from conan import ConanFile
from conan.tools.cmake import CMakeToolchain, CMake, cmake_layout, CMakeDeps


class formatRecipe(ConanFile):

    default_options = {"shared": False, "fPIC": True}

    # Sources are located in the same place as this recipe, copy them to the recipe
    exports_sources = "CMakeLists.txt", "src/*", "include/*"

    def config_options(self):

    def layout(self):
        cmake_layout(self)

    def generate(self):
        deps = CMakeDeps(self)
        deps.generate()
        tc = CMakeToolchain(self)
        tc.generate()

    def build(self):
        cmake = CMake(self)
        cmake.configure()
        cmake.build()

    def package(self):
        cmake = CMake(self)
        cmake.install()

    def package_info(self):
        self.cpp_info.libs = ["format"]

    def requirements(self):
        self.requires("fmt/10.2.1")

conan install 을 실행하여 추가한 의존성을 설치합니다.

의존성을 설치한 후에는 CMakeLists.txt 에 find_package() 와 target_link_libraries() 로 의존성을 추가해야 합니다.

cmake_minimum_required(VERSION 3.15)
project(format CXX)

add_library(format src/format.cpp)
target_include_directories(format PUBLIC include)

find_package(fmt)
target_link_libraries(format fmt::fmt)

set_target_properties(format PROPERTIES PUBLIC_HEADER "include/format.h")
install(TARGETS format)

conan build 를 사용하여 빌드를 합니다.

와 같은 에러가 발생합니다.

마지막 단계는 패키지를 사용하여 테스트하는 단계입니다.

에러가 발생한 이유는 라이브러리 헤더는 잘 설치되었지만 의존성 헤더는 설치가 되지 않았기 때문입니다.

의존성의 헤더까지 설치되게하려면 transitive_headers=True 를 추가해줍니다.

의존성을 추가했으니 라이브러리와 마찬가지로 CMakeLists.txt 에 find_package() 와 target_link_libraries() 를 사용하여 의존성을 추가합니다.

cmake_minimum_required(VERSION 3.15)
project(hello CXX)

add_executable(hello src/hello.cpp src/main.cpp)

find_package(format)
target_link_libraries(hello format::format)

install(TARGETS hello DESTINATION "."
        RUNTIME DESTINATION bin
        ARCHIVE DESTINATION lib
        LIBRARY DESTINATION lib
        )

main.cpp 에서 라이브러리 함수인 format() 을 사용해봅니다.

#include "hello.h"
#include <vector>
#include <string>

#include <format.h>

int main() {
    hello();

    format();

    std::vector<std::string> vec;
    vec.push_back("test_package");

    hello_print_vector(vec);
}

conan build 를 사용하여 빌드합니다.

$ conan build .

transitive_headers

transitive_headers 는 라이브러리의 의존성 헤더를 같이 포함하는 기능입니다. 라이브러리의 헤더에서 의존성 헤더를 include 할 때 유용합니다.

감사합니다.
