wingo pushed a commit to branch master
in repository guile.
commit c50c3a47b328c10780f4453b925a3e36d182c2bd
Author: Andy Wingo <address@hidden>
Date: Tue Mar 14 09:43:50 2017 +0100
configure detects which set of prebuilt binaries to use
* configure.ac: Use detected endianness and word size to automatically
select which set of prebuilt binaries to use.
* meta/build-env.in (top_builddir):
* meta/uninstalled-env.in (top_builddir): Update to use
SCM_PREBUILT_BINARIES for prebuilt entry in GUILE_LOAD_COMPILED_PATH.
* prebuilt/32-bit-big-endian:
* prebuilt/32-bit-little-endian:
* prebuilt/64-bit-little-endian: New links.
* prebuilt/x86_64-pc-linux-gnu: Remove this link now that it's unneeded.
