Hi there-
Do any of the ports currently work with CLANG 17 or higher?
After some work trying to get the AIX port working with IBM's new Open X=
L C 17.1, which is CLANG-based, I noticed that version 17.1.0 and 17.1.1 us=
e CLANG 13, while 17.1.2 jumps to 17, and 17.1.3 uses CLANG 19. CLANG 17 i=
s much more strict about the C standard it enforces. When the configure sc=
ript gets run, the lex test code fails to compile and while this doesn't te=
rminate the script, the LEX variable gets set incorrectly in src/config/Mak=
efile.config:
LEX =3D : -l
Obviously, that breaks the build later. I can get around it by setting =
CFLAGS=3D"-std=3Dgnu89" and then configure works successfully, but that's p=
robably not the right solution here.
Has anyone else seen anything like this? Do we need a new version of au=
totools or something?
Thanks!
-Ben
