Hello,

I need to use some C99 features but I have to add the -std=c99 option
for gcc. So how can I add this option in Eclipse?

Thanks!
(Sorry for my first mail got the wrong place, so I repost it.)

Regards
Warren Tang

For example, when I wrote this code:
for(int i = 0; i < 10; i++) {}

The gcc compiler complained that
‘for’ loop initial declaration used outside C99 mode

Hi Warren,

Simply open the project preferences and add -std=c99 to Settings/C
Compiler/Miscellaneous/Other Flags

Thanks you very much! I found it there finally.

Sorry to bring this back from the dead, but I was wondering if you knew how to do this with the current version of Eclipse and CDT.

SOLVED:
Project -> Properties
C/C++ Build -> Settings -> Tool Settings -> (Cygwin C Compiler) -> Miscellaneous
Other flags (a text field)

Note that I'm using Cygwin and you may have something different.

Is there any method of changing default flags of gcc compiler in Eclipse? I wish to apply the flag -std=c99 to all the c projects by default I create, instead of applying it project by project?

thanks in advance
