- What is the best cross-platform compiler to use for this purpose given the architecture processors? ([https://releases.linaro.org/components/toolchain/binaries/latest-7/](link url))
- In most of the guides,
rsyncis performed between a host on Ubuntu and a target on Raspbian. What directories need to be synchronized if both computers are on Ubuntu? For example, Ubuntu does not/opt/vc. - What parameters should be input to the ./config command before Qt5 compiling? Is the
-eglfsoption needed?
