There are currently only two sources of warnings left: Wcast-align and Wgnu. I am not convinced that fixing up those up is feasible so I run with them disabled to spot regressions. E.g. clang is a bit more strict wrt to unused variables with the cleanup attribute and I have fixed a number of those since. Like the other options in autogen.sh I have a shortcut for clang as well. I use 'l' for llvm. --- diff --git a/autogen.sh b/autogen.sh index e6289b3bc..91df10a26 100755 --- a/autogen.sh +++ b/autogen.sh @@ -62,6 +62,9 @@ elif [ "x$1" = "xg" ]; then elif [ "x$1" = "xa" ]; then ./configure CFLAGS='-g -O0 -Wsuggest-attribute=pure -Wsuggest-attribute=const -ftrapv' --enable-kdbus $args make clean +elif [ "x$1" = "xl" ]; then + ./configure CC=clang CFLAGS='-g -O0 -ftrapv -Wno-cast-align -Wno-gnu' --enable-kdbus $args + make clean else echo echo "----------------------------------------------------------------"
