### 3. Try to build
Building rarely works first time due to dependencies currently not being installed by Yotta, so the next step is to **try** to build.

yt build
```
For GCC, you will have to swap the CortexContextSwitch.s file with the file CortexContextSwitch.s.gcc which will be located in `/yotta_modules/microbit-dal/source`. For an example of how to do this, look below:
```
#first rename the existing one
mv yotta_modules/microbit-dal/source/CortexContextSwitch.s yotta_modules/microbit-dal/source/CortexContextSwitch.s.armcc
#then rename gcc version so that it is included by cmake
mv yotta_modules/microbit-dal/source/CortexContextSwitch.s.gcc yotta_modules/microbit-dal/source/CortexContextSwitch.s
```
This is a temporary measure until Yotta supports assembly preprocessing for armcc.
**NOTE:
To build the final hex files for the micro:bit, you will need to install the srec which can be installed via brew (`brew install srecord`), or you can install it manually from [here](http://srecord.sourceforge.net/).**
