From: Peter Eisentraut Date: Fri, 6 May 2011 19:14:53 +0000 (+0300) Subject: Improve compiler string shown in version() X-Git-Tag: REL9_1_BETA2~160 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=8dd2ede3f82505c3fd041c1953524305df0732d1;p=thirdparty%2Fpostgresql.git Improve compiler string shown in version() With some compilers such as Clang and ICC emulating GCC, using a version string of the form "GCC $version" can be quite misleading. Also, a great while ago, the version output from gcc --version started including the string "gcc", so it is redundant to repeat that. In order to support ancient GCC versions, we now prefix the result with "GCC " only if the version output does not start with a letter. --- diff --git a/configure b/configure index 3819732ca05..fc37715cd0e 100755 --- a/configure +++ b/configure @@ -29704,7 +29704,8 @@ $as_echo "$as_me: using LDFLAGS=$LDFLAGS" >&6;} # Create compiler version string if test x"$GCC" = x"yes" ; then - cc_string="GCC `${CC} --version | sed q`" + cc_string=`${CC} --version | sed q` + case $cc_string in [A-Za-z]*) ;; *) cc_string="GCC $cc_string";; esac elif test x"$SUN_STUDIO_CC" = x"yes" ; then cc_string=`${CC} -V 2>&1 | sed q` else diff --git a/configure.in b/configure.in index fa6d9e5d7c6..0a85a05641f 100644 --- a/configure.in +++ b/configure.in @@ -1849,7 +1849,8 @@ AC_MSG_NOTICE([using LDFLAGS=$LDFLAGS]) # Create compiler version string if test x"$GCC" = x"yes" ; then - cc_string="GCC `${CC} --version | sed q`" + cc_string=`${CC} --version | sed q` + case $cc_string in [[A-Za-z]]*) ;; *) cc_string="GCC $cc_string";; esac elif test x"$SUN_STUDIO_CC" = x"yes" ; then cc_string=`${CC} -V 2>&1 | sed q` else
