Description: I'm using a MySQL-recommended set of gcc compiler flags for Solaris: -O3 -fno-omit-frame-pointer -mcpu=v8 -Wa,-xarch=v8plusa MySQL compiles and runs fine but mysql_config --cflags outputs something different than the options specified in the configure: -O3 -fno-omit-frame-pointer -mcpu=v8 ,-xarch=v8plusa mysql_config has the cflags stored correctly in a variable $cflags. However, before printing the cflag string is passed through a regex which removes some options. The regex removes the "-Wa" but leaves the ",-xarch=v8plusa": cflags=`echo "$cflags " | sed -e 's;\(-DDBUG_OFF\|-DSAFEMALLOC\|-USAFEMALLOC\|-DSAFE_MUTEX\|-DPEDANT IC_SAFEMALLOC\|-DUNIV_MUST_NOT_INLINE\|-DFORCE_INIT_OF_VARS\|-DEXTRA_DEBUG\|-DHAVE_purify\|-O[0-9]\| -W[-A-Za-z]*\) *;;g' | sed -e 's; *\$;;'` The "-W[-A-Za-z]*" is the specific section causing the problem. How to repeat: Compile MySQL using gcc with "-Wa,-xarch=" cflags and then use mysql_config to get cflags. Suggested fix: Tweak the regex that cflags is passed through to match more than A-Za-z so it will either remove the entire option or not match it at all. Not sure the ramifications of changing the cleanup regex.
