sudo apt install git
install git, if it complains on ubuntu run before:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install build-essential automake checkinstall liblapack3 libblas3
(some change from http://tstur.com/2011/10/installing-rtklib.html namely liblapack3gf vs. liblapack3, libblas3gf vs. libblas3)
git clone https://github.com/tomojitakasu/RTKLIB.git
cd RTKLIB/app
sudo bash makeall.sh
edit makefile with prper bin directory, e.g. /opt/rtklib/bin and make + make install (if /opt/rtklib is user-owned, no sudo needed)
After I do "sudo bash makeall.sh", what should I do next
