ld: library not found for -l:/usr/lib/libobjc.A.dylib
这只是最新版本的错误。我正在尝试链接到/usr/lib/libobjc.A.dylib
,并且我想硬编码路径;该库保证在我所在的平台上存在于此路径。而且它确实存在:
bhaller@lanois % ls -l /usr/lib/libobjc.A.dylib
-rwxr-xr-x 1 root wheel 859536 Jan 23 08:59 /usr/lib/libobjc.A.dylib
我已经尝试过:
-L/usr/lib/ -llibobjc.A.dylib
-L/usr/lib/ -llibobjc.A
-l/usr/lib/libobjc.A.dylib
-l:/usr/lib/libobjc.A.dylib
在每种情况下,我都会收到相同的错误,即ld找不到库。但它就在那里,而且我已经提供了完整的路径!我错过了什么吗??
以下是完整的调用(包含许多其他无关的信息):

我觉得我可能只是个白痴,但我看不懂。能帮忙吗?
ld
在不同平台上有如此大的差异,所以我搜索了“man ld”,因为某种原因我的 macOS 系统无法显示ld
的 man 页面。关于 libobjc.A 和 libobjc:是的,它们之间有一个符号链接,通常情况下我会使用它,因为我熟悉这种约定。但是 https://developer.apple.com/documentation/objectivec/objective-c_runtime?language=objc 上写着“Objective-C 运行时库... 在 /usr/lib/libobjc.A.dylib 找到的共享库。”这似乎暗示我应该直接链接到 libobjc.A.dylib,出于某种原因...? - bhaller
