libpaper fails to build on OS X Tiger

[djlambe11@…]

When compiling libpaper (version 1.1.24) on OS X 10.4 the following error appears in the log:

...
ld: unknown flag: -compatibility-version
...

This is due to the fact that earlier versions of OS X used -dylib_compatibility_version, and -dylib_current_version, which shows up later. The fix, then, is to patch ltmain.sh to use the -dylib* options where necessary. The problem with this is that the latest version of OS X I can currently run is Tiger, and I don't know when the switch was made.

On the other hand, even the newest versions of OS X support the -dylib* options as a compatibility feature, so it doesn't harm anything to use them there.

Therefore, I present a patch that enables a successful build.

Could you attach the main.log file from the failed build?

This ticket is the only hit on Google for the search string "unknown flag: -compatibility-version" which makes me question the commonness of the problem or the correctness of the solution.

Sorry, that was me missing the shift key. It was -compatibility_version (noting the underscore this time). I'm uploading my main.log now.

Notes, which led me to my original conclusion: From man ld on Tiger:

-dylib_compatibility_version number
              ...
              the  library  is  used.   This  option is used as the libtool(1)
              -compatibility_version number option when its -dynamic option is
              set.

From the man page found on the hard drive of my (broken) Mavericks machine:

 -compatibility_version number
                 ...
                 is used.  This option is also called -dylib_compatibil-
                 ity_version for compatibility.

with irrelevant parts shrouded behind ellipses. If you would like the full versions, I can attach them as well. It should be noted that these are taken directly from my xterm window, and the awkward hyphenation is a by-product of man.

The 10.4 version does not have the -compatibility_version flag, nor the -current_version one. However, since my two data points are so far separated, I have no clear line to draw as to which release removed the dylib_. Being that the older option is still accepted should allow the patch to proceed without issue, but it would probably be better to use a conditional to only use the dylib_ when it is strictly necessary.
