Hi,
For development purposes, I recently turned my default compiler to be
clang on my computer since it is less permissive than gcc (CC =
/usr/bin/clang and CXX = /usr/bin/clang++),
and I forgot about it.
This is why the command :
./compile gnu
was taking clang and not gcc.
I removed my CC and CXX variables, and restart the configuration /
compilation from scratch.
I let you know if it works.
Thanks for the help.
Tom.
