I was trying to compile PHP 3 with Informix support on Digital Unix (a.k.a. Compaq Tru64, a.k.a. OSF1) with the DEC C compiler when I got a complaint about an undefined identifier: dec_t in the file functions/ifx.ec. <br> It took me a long time to figure out that the "cure" for this ill is to make sure that the compiler defines the C preprocessor identifier __STDC__. This indicates that the compiler's language is ANSI standard compliant C. <br> The definition for dec_t lives in the file /usr/informix/incl/esql/sqlhdr.h and conditional compilation macros ("#ifdef") invoke it only if __STDC__ is defined. To do this with the DEC C compiler, you must be sure to invoke it with the flag "-std". If you use GCC instead, you won't have to worry about this, since it always claims to be "standard C." <p> In case you're wondering, I was using DEC C because in my opinion it runs faster and is a bit more stable than GCC in my particular environment.
