What gcc options shall I use to enforce ANSI C (C99) warnings/errors?
gcc (GCC) 3.4.2 (mingw-special)
I’m using:
gcc -pedantic -ansi -std=c99
is this correct?
The
-ansiflag is synonymous with the-std=c89flag.Just using
-std=c99with-pedanticshould be sufficient.When in doubt, you can always refer to the GCC documentation. As of GCC 3.4.2, the chapter to read is 2 – Language Standards Supported by GCC.
