developing and validating measures of temperament in livestock - Boost failed updating 56 targets

One of these bugfixes protects you and the network from a cache invalidation issue that could allow an adversary with sufficient resources to cause a denial of service attack or chain fork.

Setting ZLIB_BINARY, ZLIB_INCLUDE and ZLIB_LIBPATH previously allowed to specify an externally compiled version of zlib with custom binary name.

Using that same logic on the older releases page, 4.1.2 is only listed as a minimum in Boost 1.53, meaning you need to upgrade GCC to at least 4.4.7, attempting to use your repositories then upgrade boost.

Please be aware that you must not upgrade GLIBC, or you may break your system.

In any case the documentation doesn't seem to properly reflect the current library behavior.

Or maybe I'm just completely misunderstanding it which is always possible.

For my use-case the whole application and dependencies (including boost) are statically linked so I have to prevent trying to link multiple versions of it when zlib is used elsewhere.

Also this external zlib has a non-standard name (libzlib.a under linux instead of libz.a).

Even though you might have followed the instruction from How to install Hedge from Git and installed (Debian/Ubuntu package g -4.3), you might have forgotten to check if you installed the basic g package.
