Building Espruino from very old release.

But the code is just taken from git release and does not have a single line change. I am assuming that it should compile straightforward.

from the compiler output it looks like some parts were compiled for different arm cpu, so maybe you tried to build it first without some options selecting nrf51 , 'make clean' will remove that

BTW, you said s110 is not harder to add in current Esprunio? What is the procedure?

The procedure is basically to become Espruino developer :-) Go over the github source and search (github search box in upper left corner) for S130 and S132 and possibly also NRF_SD_BLE_API_VERSION to get the picture of the complexity.
