"\\1\\2"
_boost_COMPILER_VERSION ${_boost_COMPILER_VERSION})
SET (_boost_COMPILER "-gcc${_boost_COMPILER_VERSION}")
Don't use this regular expression to find out the GCC version!
I filed a bug report for FindBoost.cmake
(http://public.kitware.com/Bug/view.php?id=7097) some weeks ago, that
this doesn't work reliably.
I built GCC myself with a suffix of -32, which confuses the regular
expression above. As a workaround I modified my local FindBoost.cmake to
use
STRING(REGEX REPLACE ".* ([0-9])\\.([0-9])\\.[0-9].*" "\\1\\2"
_boost_COMPILER_VERSION ${_boost_COMPILER_VERSION})
Note the blank after the initial ".*"!
