I need: > git clone https://github.com/JakobEngel/dso.git > sudo apt-get install libsuitesparse-dev libeigen3-dev libboost-all-dev > cd dso > mkdir build > cd build > cmake .. > make VERBOSE=1 Then add -v --save-temps to the gcc invocation that hits the internal compiler error. And then please paste the full output of that invocation here.
