我有 Windows 7、MSYS2、Mingw-w64-x86_64 gcc 工具链、CMake的设置，并且我正在尝试构建nanomsg 库。

这是我得到的：

$ cmake --debug-trycompile -DCMAKE_TOOLCHAIN_FILE=../toolchain_i686-pc-mingw32.cmake -DCMAKE_INSTALL_PREFIX=/usr/x86_64-w64-mingw32 -G "MinGW Makefiles" ../nanomsg

debug trycompile on

它失败并显示以下输出：

CMake 将无法正确生成此项目。调用堆栈（最近调用优先）：CMakeLists.txt:29（项目）

这是我的工具链文件：

看起来它无法建立在自动测试上，因为工具链缺少插件支持。

  1. 它与“--enable-plugin”选项（我的 gcc 中缺少）有关吗？
  2. 此选项集是否有可用的工具链构建？我在 MSYS2、Mingw-w64、rubenvb 存储库中寻找它，但它不存在。还是我自己建造？
  3. 可能 nanomsg 不需要它？自动测试是否需要它，因为 nanomsg 需要它？或者我可以阻止这个自动测试运行吗？或者我可以设置一些东西来避免“--enable-plugins”选项的需要吗？

我认为您在这里使用的是 MSYS2 shell，而不是 MSYS2 本身。如果您使用的是最新的 MSYS2，那么您将使用以下 mingw-w64 x86_64 GCC：

$ pacman -Ss mingw-w64-x86_64-gcc
mingw64/mingw-w64-x86_64-gcc 4.9.1-6

$ PATH=/mingw64/bin:$PATH gcc -v
Configured with: ... --enable-lto ...

--enable-lto 意味着 --enable-plugins 现在是默认设置，因此不会出现在列表中。

要使用 MSYS2 构建 nanomsg，请安装https://master-dl.sourceforge.net/project/msys2/Base/x86_64/msys2-x86_64-20141003.exe，取消选中“立即运行 MSYS2 shell”（你想要一个 mingw-w64 shell反而）。运行 mingw-w64 shell（开始->MSYS2 64Bit->MinGW-w64 Win64 Shell）。从该外壳中：

$ pacman -S git make mingw-w64-x86_64-cmake mingw-w64-x86_64-gcc
$ git clone https://github.com/nanomsg/nanomsg.git
$ mkdir nanomsg-build
$ cd nanomsg-build
$ cmake --debug-trycompile -DCMAKE_INSTALL_PREFIX=/usr/x86_64-w64-mingw32 -G "MSYS Makefiles" ../nanomsg
$ make install

但是，如果您是开发人员，我们将感谢PKGBUILD 对 nanomsg的贡献
