In some other compilers, I can output a message, warning, or error from the preprocessor with one of the following directives (which vary from one compiler to another): #info "my message" #warn "my message" #error "my message" or #pragma info "my message" #pragma warn "my message" #pragma error "my message" ...or other similar syntax. I tried various combinations of these, and I looked in the online GNU manual under pragmas and preprocessor directives, but I found nothing like these. Is there a way to output messages, warnings, or force errors and print associated messages, from the GCC preprocessor?
