apple-gcc42 @5666.3: "ld: unrecognized option -compatibility_version" when building jasper

[predoehl@…]

This affects my very old PowerPC system running Tiger, OS 10.4, and Xcode 2.5.

At first I could not build graphics/jasper because the linking step had two unrecognized options. Basically the build was trying to do the following:

gcc-apple-4.2 ...MANY-OPTIONS... -Wl,-compatibility_version -Wl,-current_version,2 ...

The above command failed because of the linker options, with the message,

  ld: unrecognized option -compatibility_version

After some research I managed to make a band-aid one-time fix by manually editing libtool in the build directory, like so:

OLD LIBTOOL OPTION     NEW LIBTOOL OPTION
-----------------------------------------
compatibility_version  dylib_compatibility_version
current_version        dylib_current_version

I am aware that libtool is ephemeral, created by configure, and that if I reconfigured the port, my fix would be lost. But I hope I don't need to rebuild the port often. I have no idea how to establish this fix permanently.

I do not know how to categorize the defect -- maybe it is a defect in configure, or maybe it is not a defect at all due to end-of-support for such old systems. But, I did want to report it in case it is not spurious. If I should report it elsewhere (like a GNU project mailing list), I'd be happy to, if you think it is appropriate.

Cc Me!

In the future, please fill in the Port field and Cc the port maintainers (port info --maintainers jasper), if any. As reporter, you do not need to Cc yourself.

I can’t reproduce the problem in a 10.4 VM, and I don’t understand how it could happen, as gcc-apple-4.2 should be using the linker from the ld64 port.

What do you have installed?
