Export to gcc doesn't save any file

Hello, I am trying to export the "microbit-hello-world" example to gcc (arm embedded), but after seeing in the state bar "downloading" nothing happens. I can actually export it as zip archive, but then I get a bunch of errors regarding from the assembler when trying to compile in Eclipse.

Am I missing something ?

Eventually, is there a way to convert the assembly file in a format that is understood by GNU GCC ?

Thank you very much ...

Hello, I succeeded in compiling the project making these three changes: 1) renamed BLE.h to BLEdevice.h and changed all the references 2) changed the stile of the .s file to the GNU one 3) Since i got this error: microbit/microbit-dal/source/drivers/MicroBitI2C.cpp: In member function 'int MicroBitI2C::write(int, const char*, int, bool)': microbit/microbit-dal/source/drivers/MicroBitI2C.cpp:124:35: error: too few arguments to function 'bool twi_master_init_and_clear(NRF_TWI_Type*)' twi_master_init_and_clear(); ^

I modified the call in "twi_master_init_and_clear(_i2c.i2c);"

There is a problem, though: the display doesn't seem to work properly. In particular 3 pins are always on ((1,4),(2,2) and (4,4), using 1 as a base) and some others are always off. The one working could be slightly off-place, but the "hello world" message can be recognized.

Have you any idea from where the problem could be generated ? I tried to change the display type, but it got even worse (the three pin on where the same , though ...).

Thank you for your help JP
