Hi,

i am getting the following name conflicts when building console.c on ubuntu LTS 32bit:

ChibiOS//os/hal/platforms/Posix/console.c: In function ‘putt’:
ChibiOS//os/hal/platforms/Posix/console.c:77:50: error: declaration of ‘time’ shadows a global declaration [-Werror=shadow]
ChibiOS//os/hal/platforms/Posix/console.c: In function ‘gett’:
ChibiOS//os/hal/platforms/Posix/console.c:86:39: error: declaration of ‘time’ shadows a global declaration [-Werror=shadow]
ChibiOS//os/hal/platforms/Posix/console.c: In function ‘writet’:
ChibiOS//os/hal/platforms/Posix/console.c:93:71: error: declaration of ‘time’ shadows a global declaration [-Werror=shadow]
ChibiOS//os/hal/platforms/Posix/console.c: In function ‘readt’:
ChibiOS//os/hal/platforms/Posix/console.c:103:64: error: declaration of ‘time’ shadows a global declaration [-Werror=shadow]
ChibiOS//os/kernel/src/chvt.c: In function ‘chVTSetI’:
ChibiOS//os/kernel/src/chvt.c:76:44: error: declaration of ‘time’ shadows a global declaration
ChibiOS//os/kernel/src/chschd.c: In function ‘chSchGoSleepTimeoutS’:
ChibiOS//os/kernel/src/chschd.c:189:57: error: declaration of ‘time’ shadows a global declaration
cc1: all warnings being treated as errors

Building on linux mint 15 amd64 doesn't produce this error.
It looks like libc is exporting "time" as a global symbol.

Cheers,

Vinz

Hi,

Forgot this thread... added it to the TODO list.

Please note that a lot more files are affected by this.
I added a patch which you may use as you see fit.

Hi,

Sorry, not fixing this, I would have to change 2.4.x, 2.6.x, 3.0.0 and the trunk for a warning affecting just the simulator.

You may suppress that specific warning in the makefile when building the simulator. I may perform the changes in 3.0.0 only at a later time.
