Linux cmake安裝,配置以及測試
阿新 • • 發佈:2019-02-20
安裝
cmake-3.2.2.tar.gz
解壓:tar zxvf cmake-3.2.2.tar.gz 得到 cmake-3.2.2
進入cmake-3.2.2:cd cmake-3.2.2
./bootstrap --prefix=/home/zj/cmake_install
#prefix後跟安裝目錄
make
make install
配置
vi /etc/profile
在檔案的最後一行加入
export PATH=目錄/cmake-build-3.2.2/bin:$PATH
#目錄意思是cmake-build-3.2.2的絕對地址
儲存退出後
source /etc/profile
驗證
cmake --version
出現版本號則為成功

解壓cmake.tar.gz後,在其中找到README.rst,裡面有安裝的過程:
UNIX/Mac OSX/MinGW/MSYS/Cygwin ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ You need to have a compiler and a make installed. Run the ``bootstrap`` script you find the in the source directory of CMake. You can use the ``--help`` option to see the supported options. You may use the ``--prefix=<install_prefix>`` option to specify a custom installation directory for CMake. You can run the ``bootstrap`` script from within the CMake source directory or any other build directory of your choice. Once this has finished successfully, run ``make`` and ``make install``. In summary:: $ ./bootstrap && make && make install
但是我安裝上面安裝完成後,如果不加環境變數到PATH,則沒有安裝成功。
我在下面的網頁上找到除上面外第二種方法:
新增環境變數CMAKE_ROOT,格式如下:
export CMAKE_ROOT=/home/zj/cmake_install/share/cmake3.2
其中share目錄和bin目錄屬於同一等級(個人理解,是在同一目錄下)

cmake測試
測試一:
新建資料夾cmake_demo1
進入cmake_demo1,新建檔案main.cpp:
#include <iostream> int main() { std::cout<<"Hello World!!!"<<std::endl; return 0; }
新建檔案CMakeLists.txt:
PROJECT(main)
CMAKE_MINIMUM_REQUIRED(VERSION 3.2.2)
AUX_SOURCE_DIRECTORY(. DIR_SRCS)
ADD_EXECUTABLE(main ${DIR_SRCS})
執行命令:
cmake .
make
完成後,即出現main可執行檔案,執行
測試二:
要求已安裝opencv
新建檔案加cmake_demo2
進入cmake_demo2,新建檔案test.cpp:
#include <cv.h>
#include <highgui.h>
using namespace cv;
int main(int argc, char* argv[])
{
Mat image;
image = imread(argv[1], 1);
if (argc != 2 || !image.data)
{
printf("No image data\n");
scanf("%d", &argc);
return -1;
}
namedWindow("Display Image", CV_WINDOW_AUTOSIZE);
imshow("Display Image", image);
waitKey(0);
return 0;
}
新建檔案CMakeLists.txt:
project(test)
find_package(OpenCV REQUIRED)
add_executable(test test)
target_link_libraries(test ${OpenCV_LIBS})
cmake_minimum_required(VERSION 3.2.2)
執行命令:
cmake .
make
完成後,出現test可執行檔案:
