Changeset: ed8eb74df78a for MonetDB
URL: https://dev.monetdb.org/hg/MonetDB?cmd=changeset;node=ed8eb74df78a
Modified Files:
configure.ag
Branch: Jul2017
Log Message:
Check for different function for lz4 library; use header and library checks.
Check for function LZ4_compress_fast instead of LZ4_compressBound
since the former is newer.
Don't use AC_LINK_IFELSE if there is no real need.
