Summary0012635: Building CMake with clang produces warnings in libarchive
DescriptionWhen building current git master CMake with clang (with no warning flags specified) there are several warnings nonetheless generated, see below. These are the only warnings. Perhaps they are already fixed upstream?

 You can try the upstream from here:

  http://code.google.com/p/libarchive/source/checkout [^]

It's been a long time since we first imported a snapshot of libarchive and we haven't updated it except for porting a few fixes. We've been hesitant to update because we made several portability fixes and only some went upstream, but that was back in CVS days so we don't know what they were.

This is at least the second recent issue, after 0012629, that justifies an update from upstream libarchive.

 Brad, I'm afraid I won't have time to try in the foreseeable future...

 Re 0012635:0028020: Sorry, I didn't mean to imply that I expected you to do the update. The first "you can try" suggestion was just to see if upstream builds with Clang cleanly. The rest was a general note about the approach I'd like to take for this.

It looks like upstream is pretty close to their milestone 3.0 release. That will be a good starting point for the next update.

 Seems to be fixed upstream, though there are other clang warnings, I filed a bug with them:

http://code.google.com/p/libarchive/issues/detail?id=219 [^]

That's all the time I can spend on this I'm afraid...

 I've merged to 'next' a topic that updates libarchive to a more recent upstream snapshot:

  http://cmake.org/gitweb?p=cmake.git;a=shortlog;h=f15d7576 [^]

In order to avoid diverging too much from upstream I blocked all warnings with "-w" in our build, at least until things settle.

 We've merged the libarchive update to master:

  http://cmake.org/gitweb?p=cmake.git;a=commit;h=5a5c32e1 [^]

The new build rules add "-w" for Clang so there should be no warnings.
