# Makefile for cvs-fast-export
#
# Build requirements: Read the "buildprep" script.
# You may be able to run that to install all dependencies.
#
# The C compiler must support anonymous unions (GNU, clang, C11).
#
# If you get a link error complaining that clock_gettime() can't be
# found, uncomment the line that includes -lrt in the link flags.
# You'll need this if your glibc version is < 2.17; that is for RHEL 6
# or older and Debian Wheezy or older. Alas, we can't unconditionally
# include -lrt because Darwin.
#
# You will see some meaningless failures with git 1.7.1 and older.
#
# Note: the reason for the .adoc extensions on README/NEWS/TODO is so they'll
# display nicely in GitLab's repository-browsing interface.
