C99 support

[mru22]

Some of the code I am writing is throwing errors indicating that it requires C99. Is there a way I change the Visual GDB Build settings to use C99 ?

thanks,

Hi,

Please add to CFLAGS on the Makefile settings page of VisualGDB Project Properties the following flag:

-std=c99

If you are using your own makefile, then add it to the makefile in an equivalent location so that the flag is passed to gcc.

Hello,

I’m porting Z80 code made in C99 to ARM platform, I changed my compiler directive according you suggested, but unfortunately I’m still facing compiler problems like below:

I do appreciate if some bright soul could help me in this issue.

Hi,

It’s hard to say why these errors are happening if you are using C99. Could you please share the full build log from the Output window? Perhaps you have enabled strict type checking via CFLAGS?
