[Valgrind-users] Detect Valgrind version number

[Oliver S. <ol...@f-...>]

Hello,

maybe someone can tell me whether my little shell snippet is based on
the right assumptions in order to find the Valgrind version:

valgrind --version|sed 's/valgrind-//g;s/\([0-9]*\.[0-9]\)\..*/\1/'

Can one rely on the format of the string being
"valgrind-x.y.z[whatever]" (where x.y are the major and minor version
number)?

The default seems to be "valgrind-x.y.z" but on Ubuntu I've seen
"valgrind-3.6.0.SVN-Debian" and I'm only after major and minor version
number as I presume that similar incompatibilities would not get
introduced with patch releases (where z varies).


Thanks,

// Oliver

PS: The reason has to do with the incompatibility between 3.5 and 3.6,
so I can pick the proper header when building my binary.
