麻烦构建firebreath xcode

Question

不好意思

我为浏览器做了一个插件构建一个库，它将包含firebreath上的插件并得到一个错误

链接有问题吗?或另一个吗?怎么解呢?

Answer 1

您似乎没有链接所需的库。快速的谷歌搜索表明，你需要链接到IOKit框架，至少其中一些符号。

我建议你看看Firebreath.org上的Using Libraries页面，了解如何链接到Mac框架。它看起来像这样:

find_library(FRAMEWORK_IOKIT IOKit)
target_link_libraries(${PROJECT_NAME} ${FRAMEWORK_IOKIT})

这个需要放到Mac/projectDef中。
