I am having problem using zlib with 1.4u SDK. I read it up in the
list archive and find that I should use "-lz" linker flags. I did
that but I am getting this error:
/usr/bin/ld: Undefined symbols:
_compress
_uncompress
collect2: ld returned 1 exit status
This happens even after I change SDK back to Current Mac OS.
Are you importing/including the header file?
In your project, you may wish to add libz.dylib to the project along
with the header file instead of specifying "-lz" or you could also
add "-I/usr/lib/zlib.h"
All the source files compile fine, so the header must be included.
Adding libz.dylib to project causes link error since it resolves to
libz.1.2.3.dylib which is not in 1.4u SDK.
For the time being, you can work around this by adding "-lz" to your
Other Linker Flags and removing libz.dylib from your project. I
believe this is fixed in an upcoming Xcode release.
Hope this helps,
Eric
