It is:
$ md5 /sw/var/lib/fink/path-prefix-clang/compiler_wrapper
MD5 (/sw/var/lib/fink/path-prefix-clang/compiler_wrapper) =
b7a7e0ca2661e46a0b66a4b2cb01a078
But it contains a bogus check:
-- 8< --
# To avoid extra warning spew, don't add
# -Wno-error=unused-command-line-argument-hard-error-in-future
# when clang doesn't support it .
if [ "x`clang -Wno-error=unused-command-line-argument-hard-error-in-future 2>&1
| grep unknown`" = "x" ]; then
suppress_hard_error="-Wno-error=unused-command-line-argument-hard-error-in-future"
else
suppress_hard_error=""
fi
-- 8< --
This check does not work and can not work. Indeed, behold:
$ [ "x`clang -Wfoobar`" = "x" ] && echo yesclang: error: no input files
yes
The test really needs to pass a file to clang to verify it works. Something
like this works better:
-- 8< --
opt="-Wno-error=unused-command-line-argument-hard-error-in-future"
#opt="-Wall"
if [ "x`echo | clang -E $opt - 2>&1 | grep unknown`" = "x" ]; then
suppress_hard_error="$opt"
else
suppress_hard_error=""
fi
-- 8< --
