[PATCH] Makefile: add NO_CLOCK_GETTIME check

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Some really old platforms, rhel3, which don't define CLOCK_MONOTONIC, still
need a way to build git.  Some high resolution timer code was added Jul 12,
2014 to aid debugging performance issues.  That code uses clock_gettime and
CLOCK_MONOTONIC.  That change breaks building git on ancient platforms which
don't support CLOCK_MONOTONIC, so a way to disable that code is needed.

To use this feature...

$ make NO_CLOCK_GETTIME=1

This change amends the commit...
