问题描述
我有一个正在应用中使用的第三方OS X dylib,无法轻松访问其创建者.我想确定它是否与-flat_namespace链接.那可能吗?如果可以,怎么办?
I have a third party OS X dylib that I'm using in my app and don't have easy access to its creator. I'd like to determine if it was linked with -flat_namespace. Is that possible? If so, how?
推荐答案
在库上运行otool -hV
.如果看不到TWOLEVEL
,则表明它已与-flat-namespace
链接.例如:
Run otool -hV
on the library. If you don't see TWOLEVEL
, then it was linked with -flat-namespace
. For example:
twolevel.dylib:
Mach header
magic cputype cpusubtype caps filetype ncmds sizeofcmds flags
MH_MAGIC_64 X86_64 ALL 0x00 DYLIB 8 672 NOUNDEFS DYLDLINK TWOLEVEL NO_REEXPORTED_DYLIBS
与
flat.dylib:
Mach header
magic cputype cpusubtype caps filetype ncmds sizeofcmds flags
MH_MAGIC_64 X86_64 ALL 0x00 DYLIB 8 672 DYLDLINK NO_REEXPORTED_DYLIBS
