I had no issues following my instructions, Compiling the Latest Lazarus/Free Pascal for Raspberry Pi. This was, as usual, not a short process. It takes an hour, easy, assuming no mistakes are made.
I also noticed that the compiler hits the CPU so hard that I still lost a CPU core to overheating. That’s a little disappointing.
Unless you really need the most recent version of Lazarus, just use
apt-get install lazarus
The compiler was installed and a simple program tested.
In doing this, I was reminded why I don’t run Pascal on normal RPIs. It is too slow – there is too much IO on the SD card. I have a special RPI with a USB based hard drive for that very purpose.
I have moved Lazarus programs compiled on the RPI to the OPI and they work fine.
I expect that will conclude my testing with the Orange Pi One. I have now ordered an Orange Pi PC which has a faster CPU and more IO options to experiment with.
