I say about general idea for compatibility. So people can use libmaple not only with GCC and may be expand libmaple as alternative for ST standard library. </p> http://forums.leaflabs.com/topic.php?id=1167#post-7147 Fri, 11 Nov 2011 20:32:13 +0000 gbulmer 7147@http://forums.leaflabs.com/ <p>x893 - Are you sure the two declarations are equivalent?

Problem in new features of GCC which not supported with RealView ARMCC. It's not a big changes to make code to comtible with other arm compilers.<br /> For example</p> <p>typedef struct timer_dev {<br /> timer_reg_map regs; /**&lt; Register map */<br /> rcc_clk_id clk_id; /**&lt; RCC clock information */<br /> timer_type type; /**&lt; Timer's type */<br /> voidFuncPtr handlers[]; /**&lt; User IRQ handlers */<br /> } timer_dev;</p> <p>initialization this structures not support by ARMCC but if you change</p> <p> voidFuncPtr handlers[]; /**&lt; User IRQ handlers */<br /> to<br /> voidFuncPtr *handlers; /**&lt; User IRQ handlers */</p> <p>all OK</p> <p>Changes in codes minimal but your code can be used this other system - Keil, IAR and may be other. I check only with Keil and IAR </p>
