Problem installing PULP-SDK

[cello]

Hi, I followed the same steps with jmmarostegui but I got following error when executing make all after
source configs/pulpissimo.sh. At some point I got this error.

sdk:pulp-rt:prepare (pulpissimo@config_file=chips/pulpissimo/pulpissimo.json): make header
make[1]: Entering directory '/opt/riscv/pulp-sdk/runtime/pulp-rt'
make[1]: Nothing to be done for 'header'.
make[1]: Leaving directory '/opt/riscv/pulp-sdk/runtime/pulp-rt'
Reached EOF with exit status 0
