sudo in front worked!
Got further but now got an error when performing this command
sudo mkdir ~/Gridcoin-Research/src/obj && cd ~/Gridcoin-Research/src && chmod 755 leveldb/build_detect_platform && make -f makefile.unix
This is what it gave me
alert.cpp:273:1: fatal error: opening dependency file obj/alert.d: Permission denied
}
^
compilation terminated.
makefile.unix:173: recipe for target 'obj/alert.o' failed
make: *** [obj/alert.o] Error 1
I've looked into the launchpad method too but I'm unable to run the
sudo add-apt-repository ppa:gridcoin/gridcoin-stable
I get this error
sudo: add-apt-repository: command not found
This is on a Raspberry Pi 3 running Raspbian.
You will need to flash your SD card with Ubuntu for the launchpad to work I think, I never used it myself.
Re the error, Im not sure whats causing you to get a permission denied, all I can think of is trying:
'sudo mkdir ~/Gridcoin-Research/src/obj && cd ~/Gridcoin-Research/src && chmod 755 leveldb/build_detect_platform && sudo make -f makefile.unix' but if that doesnt work Im not sure how to resolve, sorry
