Question

I have a header with the following style of declarations:

extern struct xvimage *allocimage(char * name, int32_t rs, int32_t cs, int32_t ds, int32_t t);
extern struct xvimage *allocmultimage(char * name, int32_t rs, int32_t cs, int32_t ds, int32_t ts, int32_t nb, int32_t t);
etc...

Trying to compile it yields error E1127 “Type required in parameter list”, immediately followed by E1022: Missing or misspelled data type near ‘int32_t’.

I have already enabled implemented C99 extensions using the switch -za99. I am using the latest version of OpenWatcom (v1.9). I believe this project compiled nicely with gcc on linux.

What is wrong with these declarations? I don’t even understand the error message. What should I do?

Answer 1

The int32_t type is defined in the <stdint.h> header, so make sure that one is included at the top of your header file.
