cmake 사용법 예제

cmake는 이미 설치되어 있다고 가정한다.

디렉토리는 다음과 같은 상태 입니다. 

test     

- Demo

- Hello

test, test/Demo, test/Hello 폴더에 각각 CMakeLists.txt파일을 아래 내용대로 생성한다.

총 3개의 CMakeLists.txt파일을 생성한다.

test/CMakeLists.txt

# The name of our project is "HELLO". CMakeLists files in this project can # refer to the root source directory of the project as ${HELLO_SOURCE_DIR} and # to the root binary directory of the project as ${HELLO_BINARY_DIR}. cmake_minimum_required (VERSION 2.6) project (HELLO)   # Recurse into the "Hello" and "Demo" subdirectories. This does not actually # cause another cmake executable to run. The same process will walk through # the project's entire directory structure. add_subdirectory (Hello) add_subdirectory (Demo)

 

test/Hello/CMakeLists.txt

# Create a library called "Hello" which includes the source file "hello.cxx". # The extension is already found. Any number of sources could be listed here. add_library (Hello hello.c)

 

test/Demo/CMakeLists.txt

# Make sure the compiler can find include files from our Hello library. include_directories (${HELLO_SOURCE_DIR}/Hello)   # Make sure the linker can find the Hello library once it is built. link_directories (${HELLO_BINARY_DIR}/Hello)   # Add executable called "helloDemo" that is built from the source files # "demo.cxx" and "demo_b.cxx". The extensions are automatically found. add_executable (helloDemo demo.c)   # Link the executable to the Hello library. target_link_libraries (helloDemo Hello)

 

test/Demo, test/Hello폴더에 아래와 같은 소스코드를 작성한다.

test/Demo/demo.c

#include<stdio.h> #include"hello.h"   int main() {       hello();       return 0; }

 

test/Hello/hello.h

#include<stdio.h>   #ifndef __HELLO_H__ #define __HELLO_H__   void hello();   #endif

 

test/Hello/hello.c

#include"hello.h"   void hello() {       printf("안녕하세요?\n"); }

 

위와 같이 작성한 후 아래와 같이 cmake를 실행하여 Makefile을 만들고, 만들어진 Makefile을 사용하여 실행파일을 생성한다.

 

[myid@localhost test]$ cmake CMakeLists.txt

-- Configuring done

-- Build files have been written to: /home/myid /test

[myid@localhost test]$ make

[100%] Built target helloDemo

[myid@localhost test]$ cd Demo/

[myid@localhost Demo]$ ./helloDemo

안녕하세요?
