It isn't installed, as far as I can see. I expected it's in some optional package that is absent on that build platform. Although cfarm119 does have a file /opt/freeware/include/zlib.h, that corresponds to /opt/freeware/lib/libz.a, not to what -lz picks up which is /usr/lib/libz.a (a symlink to /usr/opt/rpm/lib/libz.a). I wouldn't recommend mixing up versions like that. > It's too late to make serious changes in the configury on the release > branch, but maybe we should simply disable HAVE_ZLIB_H on AIX? Then > we could find a proper solution on master. Not sure that would be a good idea as this isn't an AIX-specific problem. Anybody can mess up .h and -l in this way, on any OS. On the same platform I discovered a similar problem with -lsqlite3. I fixed both problems on master by installing the attached, and I'm marking the bug as done. For the release branch I suppose we can just say something like "just use --without-zlib if you have problems". As I'm sure you know, this library configury is waaay too complex and idiosyncratic. Why don't libz and libsqlite3 use pkg-config, for example? But I'm inclined to let the relevant library experts deal with that whenever they have time. --------------lRYw71vFF6jGCfVNaeUNhl0G Content-Type: text/x-patch; charset=UTF-8; name="0001-Port-better-to-AIX-7.3-with-lz-but-not-zlib.h.patch" Content-Disposition: attachment;
