config.h.in 中引用了CMakeLists.txt中定义的两个版本号,如下所示: #defineTutorial_VERSION_MAJOR @Tutorial_VERSION_MAJOR@#defineTutorial_VERSION_MINOR @Tutorial_VERSION_MINOR@ main.cpp文件直接引用config.h头文件中定义的版本号,如下所示: #include"config.h"#include<iostream>usingnamespacestd;intmain()...
When CMake configures this header file the values for @Tutorial_VERSION_MAJOR@ and @Tutorial_VERSION_MINOR@ will be replaced by the values from the CMakeLists.txt file. Next we modify tutorial.cxx to include the configured header file and to make use of the version numbers. The resulting s...

在CMakeLists.txt中添加设置option,这个设置会在CMake-Gui中显示。 option(USE_MYMATH"Use tutorial provided math implementation"ON)# configure a header file to pass some of the CMake settings to the source code.configure_file(TutorialConfig.h.inTutorialConfig.h)if(USE_MYMATH)add_subdirectory(MathF...
文件中的命令支持大写、小写或者混合使用,这个例子中的命令使用小写。tutorial.cxx 用于计算一个数的平方根,源码的第一版非常简单: // 计算一个数的平方根 #include <stdio.h> #include <stdlib.h> #include <math.h> int main (int argc, char *argv[]) ...

The source code is located under the src directory, with each project having its own sub-directory. There is also an include directory, on the same level with src. CMakeLists.txt scripts need to be created in each of the src subfolders, as well as in the root. cmakedemo/ ├── inc...
CMake 检查目标的POSITION_INDEPENDENT_CODE属性,并适当地添加编译器特定的编译标志,如gcc或clang的-fPIC。 PIC 这个词有点让人困惑。现在,程序已经在某种意义上位置无关,因为它们使用虚拟内存来抽象实际的物理地址。在调用函数时,CPU 使用对每个进程来说都是0的物理地址,该物理地址在分配时可用。这些映射不必指向...
# 设置编译的参数-fPICset(CMAKE_POSITION_INDEPENDENT_CODEON) -fPIC作用于编译阶段,告诉编译器产生与位置无关代码(Position-Independent Code),则产生的代码中,没有绝对地址,全部使用相对地址,故而代码可以被加载器加载到内存的任意位置,都可以正确的执行。这正是共享库所要求的,共享库被加载时,在内存的位置不是...
