Dear all I am trying to pass -Wall option to AM_AUTOMAKE : AM_INIT_AUTOMAKE([-Wall foreign]) The configure.ac also have LT_INIT Unfortunately, after launching autoreconf -i, I don' t see my Wall option, neither in the generated Makefile, not configure script.. And, in the end, it's not visible in the libtool command launched... What do I miss ? Thank you for your help.
