Exported project from Mbed compiler to eclipse gcc arm has errors

[Tarik]

Hi, After following all instructions on: gnuarmeclipse.github.io/.../ And after installing all Nordic Semi dependencies on eclipse.

I import on eclipse the UART_Loopback project, but whenever I try to compile I get errors like:

1. "Symbol 'NULL' could not be resolved"

2. "Type 'uint16_t' could not be resolved" and many other errors which I think are produced by the previous errors. Example:

3. "Invalid arguments, Candidates are: enum ble_error_t accumulateAdvertisingPayloadTxPower(?)

I guess it's some configuration issue with eclipse and the GNU ARM toolchain but I can't find out how to solve it.

Thanks a lot for your help

Following this Tutorial solved the problem: devzone.nordicsemi.com/.../

Another thing is to not use Eclipse Neon and use Eclipse Mars instead.
