第六章:使用 CMake 进行链接 你可能会认为,在我们成功将源代码编译成二进制文件之后,作为构建工程师我们的工作就完成了。事实几乎如此——二进制文件包含了 CPU 执行的所有代码,但代码分散在多个文件中,方式非常复杂。链接是一个简化事物并使机器代码整洁、易于消费的过程。 快速查看命令列表会让你知道 CMake 并没...
Vcruntime 库包含与编译器相关的功能,例如异常处理和内部函数。 如果你使用的是默认项目设置,则此更改不会对你产生影响,因为链接器将自动使用新的默认库。 如果将项目的“链接器”属性“忽略所有默认库”设置为“是”,或使用的是命令行上的 /NODEFAULTLIB 链接器选项,则必须更新库的列表(位于“附加依赖项”属性...

以我自身经历为例,本人最开始是通过ROS wiki上的CMakeList.txt示例学习的,甚至我都没有理解“CMake是什么东西、CMake背后的设计理念是什么”就直接使用了,一个“catkin_make”命令解决所有的问题。然后就是遇到具体CMake问题后在网络上零零散散地临时学习一下怎么具体的使用,但是随着接触的代码工程越来越大、代码...
对于clangd 等静态检查或代码提示工具,需要 CMake 提供compile_commands.json,这通常放置在 build/内,内容大致为如下形式 [ { "directory": "D:/codeRoot/Demo2/build/src", "command": "G:\\mingw64\\bin\\c++.exe @CMakeFiles/Main1.dir/includes_CXX.rsp -O3 -DNDEBUG -std=c++17 -o CMakeFiles...
This is because we don't know how many vertices the graph will have and so we cannot create an array of Linked Lists at compile time. Adjacency List C++ It is the same structure but by using the in-built list STL data structures of C++, we make the structure a bit cleaner. We are...
