Re: GCC 4.8.1 unable to compile a .c File

[Vinaya Dandur <mail2vinaya at gmail dot com>]

Hi Jonathan,

Thank you. Yes it is not an issue with the GCC but the TRAP_BRKPT is
defined in signal.h which the GCC could include but can't find the constant
mentioned.
Is there any way this problem could be resolved ? any pointers I can get ?

Thanks and Regards,
Vinaya D R
