(solved) Error flagged on this line of code:

[mzimmers]

Code: Select all

#include <stddef.h>
#define hexstrtobyte(a) strtol(a, NULL, 16)

expected declaration specifiers or '...' before '(' token

Can someone tell me what I'm doing wrong here? I tried this code in a different IDE, and it seemed to work.

Thanks...

What IDE is this? Does the IDE flag the code, or does the compiler?

[mzimmers]

Hi Sprite - sorry; I should have mentioned this is VS Code.

I get the error when I build, so I guess it's the compiler.

That actually brings up another question I had, though: currently, errors are found/cleared on build. How do I get the errors to update without building?

1. Check for earlier errors in the output. The quoted error may be misleading consequence of some earlier error (eg. strtol not defined).
2. #include <stdlib.h>
3. Double check every usage of the macro, the error is likely going to be there rather than within its definition.

Hi boarchuz - you were right; the problem wasn't with the macro itself. It was with a header file earlier in the file, which itself included another header that couldn't be found.

I'm sure I can configure VS Code to make these kinds of problems more obvious; I just haven't found out how yet.

Thanks for the help.
