CMake多体系结构编译 [英] CMake Multiarchitecture Compilation

问题描述

我想知道如何编写一个CMake安装程序，允许使用任何编译器和操作系统对x86和x64架构进行编译。

解决方案

这将是巨大的，如果CMake有一个32 / 64bit的选项开箱。它不会，所以你将需要应用不同的编译器或生成器依赖方法之一。例如：

• GCC（在Linux上）和其他一些编译器，例如太阳工作室。设置 CFLAGS 和 CXXFLAGS 以包括 -m32 位构建）或 -m64 （64位构建）。




• 使用64位发生器，例如。

  
  
  

  cmake -GVisual Studio 10 Win64path\to\source\dir

  
  
  

  编译64位（x64）。使用 CMAKE_OSX_ARCHITECTURES 在生成器名称中省略Win64以构建32位



• CMake变量。
  
  
  

  cmake -DCMAKE_OSX_ARCHITECTURES = i386 / path / to / source / dir
  将编译32位版本

  
  
  

  cmake -DCMAKE_OSX_ARCHITECTURES = x86_64 / path / to / source / dir
  将编译64位。

  
  
  

  cmake-DCMAKE_OSX_ARCHITECTURES = x86_64; i386/ path / to / source / dir 将创建96位通用二进制文件：）

上述内容稍作修改。

I want to know how I could write a CMake setup which allows compilation for both x86 and x64 architectures using any compiler and OS.

解决方案

It would be great if CMake had an 32/64bit option out of the box. It does not, so you will need to apply one of different compiler or generator dependend methods. E.g.:

• GCC (on Linux) and some other compilers, e.g. Sun Studio. Set CFLAGS and CXXFLAGS to include -m32 (32-bit build) or -m64 (64-bit build).

• Windows, Visual Studio generator. Use 64 bit generator, e.g.

  cmake -G "Visual Studio 10 Win64" path\to\source\dir

  to compile 64-bit (x64). Omit "Win64" in generator name, to build for 32 bit

• Mac OS X. Use CMAKE_OSX_ARCHITECTURES CMake variable.

  cmake -DCMAKE_OSX_ARCHITECTURES=i386 /path/to/source/dir will compile 32 bit build

  cmake -DCMAKE_OSX_ARCHITECTURES=x86_64 /path/to/source/dir will compile 64 bit.

  cmake "-DCMAKE_OSX_ARCHITECTURES=x86_64;i386" /path/to/source/dir will create 96-bit universal binaries :)

The above is slightly reworded.
