Subject: Fix: force the use of our _FORTIFY_SOURCE definition
X-Git-Tag: v2.11.2~6
X-Git-Url: https://git.lttng.org/?a=commitdiff_plain;h=6aec8e11daa4ddac37fa4faca2cea88ce500089e;hp=6aec8e11daa4ddac37fa4faca2cea88ce500089e;p=lttng-tools.git

Fix: force the use of our _FORTIFY_SOURCE definition

Some toolset (ubuntu) already defined the _FORTIFY_SOURCE.

This removes the warning we see if this is the case. Unset the variable and
reset it.

The warning:

make[3]: Entering directory '/home/joraj/lttng/master/lttng-tools/tests/regression/kernel'
  CC       select_poll_epoll-select_poll_epoll.o
<command-line>: warning: "_FORTIFY_SOURCE" redefined
<built-in>: note: this is the location of the previous definition
  CCLD     select_poll_epoll
