问题
My application builds and runs fine on 10.6. I have Base SDK set to 10.6 and Mac OS X Deployment Target set to 10.5.
My application uses the system libcurl.dylib — instead of adding the dylib to the project, I just add -lcurl to the linker flags in build settings. (Though I have tried it both ways.)
When I launch the application on 10.5.8, I get the following error
Dyld Error Message: Library not loaded: /usr/lib/libcurl.4.dylib
Referenced from: /Applications/My Application.app/Contents/MacOS/MyApplication
Reason: Incompatible library version:
MyApplication requires version 6.0.0 or later, but libcurl.4.dylib provides version 5.0.0
Sure enough, if I otool -L the application's binary, I get the following for libcurl:
/usr/lib/libcurl.4.dylib (compatibility version 6.0.0, current version 6.1.0)
Is there any way around this, or should I just statically link my own libcurl build?
回答1:
Have you tried setting the Base SDK to 10.5 as well?
$ otool -L /Developer/SDKs/MacOSX10.6.sdk/usr/lib/libcurl.4.dylib
/Developer/SDKs/MacOSX10.6.sdk/usr/lib/libcurl.4.dylib:
/usr/lib/libcurl.4.dylib (compatibility version 6.0.0, current version 6.1.0)
...]
$ otool -L /Developer/SDKs/MacOSX10.5.sdk/usr/lib/libcurl.4.dylib
/Developer/SDKs/MacOSX10.5.sdk/usr/lib/libcurl.4.dylib:
/usr/lib/libcurl.4.dylib (compatibility version 5.0.0, current version 5.0.0)
