Question

抱歉我的英文

我为浏览器制作插件以进行firebreath 构建ois库，它将包含firebreath上的插件并获得错误

链接问题？或其他？我该如何解决？

Answer 1

您似乎没有链接所需的库。 quick google search表示您需要链接到IOKit框架以获取至少其中一些符号。

我建议您查看Firebreath.org上的Using Libraries页面，了解有关如何链接到Mac框架的信息。它看起来像这样：

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

这需要在你的add_mac_plugin调用之后的某个地方进入Mac / projectDef.cmake。

麻烦建立firebreath xcode
