gyp - 如何指定链接库风格

【中文标题】gyp - 如何指定链接库风格

【英文标题】：gyp - how to specify link library flavor

【发布时间】：2012-12-08 10:14:54

【问题描述】：

我正在编写一个本地节点模块，我希望能够在发布和调试版本中构建它。

节点模块链接到另一个库，该库在两个不同的目录中具有调试和发布版本。

现在这就是我卡住的地方 - 我如何为正在构建的当前配置指定库目录？

我尝试在configuration.debug.link_settings 键中设置它，但我收到错误： '在调试配置中不允许链接设置，在目标 binding.gyp 中找到

【参考方案1】：

显然，这在跨平台方式中是不可能的。 因此，希望这可以节省您几个小时的实验时间。

这是一个为 Mac 和 Windows 构建插件的 gyp 文件。

//This example assumes you have an external library 'thelibrary', located in 
//./external/thelibrary
//With the two flavors, debug and release in lib/debug and lib/release

【讨论】：

附加找到正确的设置名称使用MSVSSettings.py

【参考方案2】：

我也遇到过这个问题，如果您在命令行上传递 --format=make-linux （例如），它将为“make”格式生成，但它会显式使用“linux”风格.
