Hi, I recently noticed that portage executes the file bashrc located in /etc/portage before every ebuild. This way it can be used to set the -mcpu and -mtune flags correctly. If you add the following to this file everything goes automatically:
<--- SNIP ---> # Automatically replace -mtune= with -mcpu if not supported by gcc # and vice versa. echo "" | gcc -mtune=i386 -E - > /dev/null 2> /dev/null if [ $? == 0 ]; then export CFLAGS=`echo $CFLAGS | /bin/sed 's/-mcpu=/-mtune=/'` export CXXFLAGS=`echo $CXXFLAGS | /bin/sed 's/-mcpu=/-mtune=/'` else export CFLAGS=`echo $CFLAGS | /bin/sed 's/-mtune=/-mcpu=/'` export CXXFLAGS=`echo $CXXFLAGS | /bin/sed 's/-mtune=/-mcpu=/'` fi <--- SNIP ---> Maybe someone can give me a feedback if this is good idea or if I missed something for some exotic situation this will fail. Why doesn't portage do this automatically by itself? If it encounters an -mtuneÂ= option in make.conf and gcc doesn't support it it replaces it with -mcpu=?!
