error: 'for' loop initial ....

doggiedoc

...declarations are only allowed in C99 mode.
Note: use option -std=c99 or -std=gnu99 to compile your code.

How do I select this option? I've tried adding -std=c99 to "Other Compile Options" but get waaaay more errors after that.

Thanks!

PS: obviously I could just declare the variable in a separate statement but the thing is I kinda like declaring it inline with the 'for' statement.

PPS: Using Mac OS 10.8 and SIDE version 0.7.2

So... most of the new errors are warnings about local variables but the inline declaration in the for loop mentioned about still doesn't seem to work. I realize I am doing something wrong. I just don't know what.

well, inline declaration works, but that variable is declared only if first loop and only for that loop!
you need to declare it again in second loop! line 93
and for warnings, without more code it's hard to tell...

my 1.2 cents...

Thank you! You just taught me how to read the error line output! Now I understand!!
