zlib version check
by Ulrich Mueller 02 Aug '12

02 Aug '12

Forwarding downstream bug report <https://bugs.gentoo.org/310487>. LuaTeX does a check if the version of the zlib shared library when executing agrees with the zlib version used at build time. IMHO, this check does more harm than good: - LuaTeX will refuse to run after every minor upgrade of zlib (e.g. if upgrading from zlib-1.2.6 to zlib-1.2.7) and needs to be rebuild. - There's no good way for automatic tools to detect this. See the downstream bug for details. - The full zlib version is the wrong thing to check. Changes in zlib's ABI are tracked by its soname (i.e. libz.so.1); the dynamic linker already takes care that the right version will be used. - In addition to this, zlib's deflateInit* and inflateInit* functions contain another version check, which looks at the initial version component only. So in total, the zlib version is checked at three different places (each time differently!). So, would it be possible to remove the check for the zlib version? See patch included below.
