C89 Does Not Appear To Be The Default Language

Kier

Hello,

I'm using CCS12.4.

The compiler manual says: • ANSI/ISO C89 (--c89, default for C files)

When I compile with the language (-std) set to empty (and therefore the default) in CCS GUI...

,...my program builds just fine.

But when I select 'c89' I get all sorts of errors.

The implication is that c89 is not the default language despite what the manual claims.

Please confirm what the default language is.

What does __STDC__ or __STDC_VERSION__ say?

I think C99 is the default.

Good idea. When I hover over this it says: 201710

Does that mean c17?

Looks like 201710 is gnu17. That's a long way from c89!

Similar to this other forum thread, you are using the wrong compiler manual.

Ah, I see. Thank you.

In my defence, there is only one ARM compiler manual listed under CCSTUDIO IDE, configuration, compiler or debugger | TI.com. To someone who's new to ARM that is the obvious (and only) choice.

Please add the HTML link for the tiarmlang manual.
