BUG: tsocks-1.8beta5_1 can't resolve libSystem symbols

[darren.bane@…]

the error log can be found here: INLINE

Description: When preloaded using DYLD_INSERT_LIBRARIES, libtsocks.dylib can't resolve symbols from libSystem.dylib like close and connect.

Comments: I used a sh-compatible shell. I also tried setting DYLD_INSERT_LIBRARIES to "/opt/local/ lib/libtsocks.dylib:/usr/lib/libSystem.dylib", to no avail.

I fixed this. The problem is that the symbol _init isn't special to dyld, like it would be in an ELF system. The solution from ​http://developer.apple.com/documentation/DeveloperTools/Conceptual/DynamicLibraries/Articles/DynamicLibraryDesignGuidelines.html#//apple_ref/doc/uid/TP40002013-SW17 is in the attached patch.

Declares _init as having attribute((constructor))

Ah, I'm no good at driving Bugzilla. What I meant to do in the previous post was make the definition of _init static.
