Hi,
I got this error when I compiled the program in Linux platform:
'error: conflicting types for 'sbp_pos_lookup_1'
'error: previous declaration of 'sbp_pos_lookup_1' was here
but it works fine and has been successfully compiled in AIX.
This is the part of the code:
#ifdef __STDC__
struct sbp_pos_msg *sbp_pos_lookup_1(struct sbp_pos_msg *);
.
.
#else
struct sbp_pos_msg *sbp_pos_lookup_1();
.
.
#endif
Any input? Thanks.
'error: conflicting types for 'sbp_pos_lookup_1'
'error: previous declaration of 'sbp_pos_lookup_1' was here
So does your implementation of sbp_pos_lookup_1 actually match the declaration when STDC is defined (which it is under GCC/Linux)
#ifdef __STDC__
struct sbp_pos_msg *sbp_pos_lookup_1(struct sbp_pos_msg *);
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
Thanks, Salem for your response.
Yes, it matches the declaration. I'm actually getting the error in this line
struct sbp_pos_msg *sbp_pos_lookup_1();
It was actually successfully compiled and it works fine in AIX, but when I tried to compile in Linux, I'm getting this error.
error: conflicting types for 'sbp_pos_lookup_1'
Any input? Thanks.
So what does it look like at the "previously declared as line"?

That is the first statement after the 'else' statement. That's where I'm getting the compile error.
This is the part of the code:
#ifdef __STDC__
struct sbp_pos_msg *sbp_pos_lookup_1(struct sbp_pos_msg *);
.
.
#else
struct sbp_pos_msg *sbp_pos_lookup_1();
.
.
#endif
Any idea? Thanks.
Yes, but itīs the one "previously declared as" which is important.
Mostly, such error messages print a filename and a line number. Maybe you should post those as well.

Here are the files indicated in the error:
sbp_pos.c:21: error: conflicting types for 'sbp_pos_lookup_1'
sbp_svr.h:80: error: previous declaration of 'sbp_pos_lookup_1' was here
Line 21 points to this part of the code which is after the #else statement
#else
struct sbp_pos_msg *sbp_pos_lookup_1(); <---Line 21
Why is your .c file also prototyping the function already prototyped by the .h file?
> #else
And does the .c / .h have the same pre-processor logic?
10 lines either side of the actual error line would be useful.
As would knowing where struct sbp_pos_msg is actually declared.
