Hi, Stephen. You can add '-v' into your command line to see what predefinitions has been used when compling. Most of predefinitions has been added in the build time, but your can still enable yours by '-D' and disable by '-U', or just add them into your spec of cross complier. ---cut from gcc.info------- `-DMACRO' Define macro MACRO with the string `1' as its definition. `-DMACRO=DEFN' Define macro MACRO as DEFN. All instances of `-D' on the command line are processed before any `-U' options. `-UMACRO' Undefine macro MACRO. `-U' options are evaluated after all `-D' options, but before any `-include' and `-imacros' options. ----------------------------- There is a chapter mention some standard and nonstandard predefine macros in the cpp.info (/Macros/Predefined Macros) ----- Original Message ----- From: "Stephen Smith" <ischis2@home.com> To: "CrossGCC" <crossgcc@sourceware.cygnus.com> Sent: Thursday, February 22, 2001 6:53 AM Subject: GCC predefinitions > How can I get gcc to dump the predefinitions.
