问题
I've been fighting Xcode for two days now trying to get a dylib built and then loaded by an executable and am having persistent dyld: Library not loaded: errors.
I am now at the point where I have my executable in one directory (/Users/drew/Development/Tools/bin - my personal bin directory) and the dylib in another directory (/Users/drew/Development/lib - my personal lib directory).
The application is a command line app and the otool -L output for it is as below
otool -L configcompiler
configcompiler:
"/Users/drew/Development/lib/WSWebScraper dylib.dylib" (compatibility version 1.0.0, current version 1.0.0)
/usr/lib/libxml2.2.dylib (compatibility version 10.0.0, current version 10.8.0)
/System/Library/Frameworks/CoreData.framework/Versions/A/CoreData (compatibility version 1.0.0, current version 407.5.0)
/System/Library/Frameworks/Foundation.framework/Versions/C/Foundation (compatibility version 300.0.0, current version 945.0.0)
/usr/lib/libobjc.A.dylib (compatibility version 1.0.0, current version 228.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 169.3.0)
/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 744.0.0)
The dylib file definitely exists in the 'lib' location
ls -l "/Users/drew/Development/lib/WSWebScraper dylib.dylib"
-rwxr-xr-x 1 drew staff 246996 20 Aug 11:43 /Users/drew/Development/lib/WSWebScraper dylib.dylib
...but the application reports the error as below.
./configcompiler
dyld: Library not loaded: "/Users/drew/Development/lib/WSWebScraper dylib.dylib"
Referenced from: /Users/drew/Development/Tools/bin/./configcompiler
Reason: image not found
Trace/BPT trap: 5
I've been staring at this for too long now and probably can't spot the glaringly obvious - another pair of eyes may spot the error. Thanks for any assistance you can give.
