Bug description:Test for -fvisibility=hidden support fails with certain $CC
Description:
------------
There is a check in configure.in that looks for -fvisibility=hidden
support when the user is building with GCC:
dnl activate some gcc specific optimizations for gcc >= 4
if test "$GCC" = "yes"; then
case $host_alias in
*darwin*)
GCC_MAJOR_VERSION=`$CC -dumpversion | /usr/bin/sed -nE
'1s/([[0-9]]+)\.[[0-$
;;
*)
GCC_MAJOR_VERSION=`$CC --version | $SED -n
'1s/[[^0-9]]*//;1s/\..*//;1p'`
;;
esac
if test $GCC_MAJOR_VERSION -ge 4; then
CFLAGS="$CFLAGS -fvisibility=hidden"
fi
fi
The idea is to parse off the major version number from the end of the
"gcc --version" output, and see if it's 4 or more. However, the regular
expression in question doesn't work when $CC is a little weird. This is
the expected result, with a vanilla GCC:
$CC --version | sed -n '1s/[[^0-9]]*//;1s/\..*//;1p'
4
But this is what happens when my CC is set:
CC=x86_64-pc-linux-gnu-gcc
$ $CC --version | sed -n '1s/[[^0-9]]*//;1s/\..*//;1p'
x6_64-pc-linux-gnu-gcc (Gentoo Hardened 4
