Bug 3308

Summary: Library's data of dependent shared library is incorrect.
Product: SDL_image Reporter: s172262
Component: miscAssignee: Sam Lantinga <slouken>
Status: NEW --- QA Contact: Sam Lantinga <slouken>
Severity: normal    
Priority: P2    
Version: 1.2.12   
Hardware: x86_64   
OS: Mac OS X (All)   

Description s172262 2016-04-13 13:13:53 UTC 
The libSDL_image.dylib building with --enable-feature-shared (e.g. --enable-png-shared) has no data of dependent shared library for specify librarys.
It may be correct because there is no shared symbol in libSDL_image.dylib against options.

But the library with --enable-feature-shared=no has data against it has no shared symbol.
The following library was built with --enable-jpg-shared=no, --enable-png-shared=no, --enable-tif-shared=no and --enable-webp-shared=no.

It is inverse. And There is other strange point about libz.
