Hi
I'm trying to add a check to my configure.ac to determine if clang is
being used, I have the following:
CLANG_CC=
if test "$GCC" = yes; then
if test "`$CC -v 2>&1 | grep -c 'clang version'`" != "0"; then
CLANG_CC=1
fi
fi
And I'm trying to use AS_IF instead, I've been reading to
documentation[1], and have come up with the following:
AS_IF([test "$GCC" = yes],[
[AS_IF([test "`$CC -v 2>&1 | grep -c 'clang_version'`" != "0"],[CLANG_CC=1])],
[CLANG_CC=])
but it doesn't seem to be working, whereas the version using if does.
Therefore I must be incorrectly constructing the nested use of AS_IF.
Can anyone spot what I'm doing wrong? Or know of a better way to check
if clang is being used?
Cheers
Adam
