Latest mbed-dev doesn't link

I'm getting a ton of linker errors when I try to use the latest version of mbed-dev on the online compiler. Anyone have any ideas?

NOTE: The site isn't letting me add the error log to this post because it "doesn't look like useful content"???

Hi Neil,

Sorry for the issues you're having.

What target are you using?

The problem is not bound to a specific target. The linking errors occur with all targets, when compiling with mbed-dev. The problem is that in mbed-dev in folder "common" there are several double definitions. A lot of newer files with mbed_ suffix were added but the corresponding older files (without mbed_ suffix) were not removed accordingly, so the same definitions are in both files. The files in question are:

gpio.c and mbed_gpio.c
assert.c and mbed_assert.c
semihost_api.c and mbed_semihost_api.c
wait_api.c and mbed_wait_api.c
error.c and mbed_error.c
ticker_api.c and mbed_ticker_api.c
us_ticker_api.c and mbed_us_ticker_api.c
board.c and mbed_board.c
pinmap_common.c and mbed_pinmap_common.c
rtc_time.c and mbed_rtc_time.c

Confirmed, removing the older files fixes the problem.

Thanks for confirmation Neil.

@mbed-Team: Can someone from the mbed-Team please apply the fix to the current release of mbed-dev, so that others don't stumble over the same problem?

Thanks and best regards
Nenad
