The idea behind Lazarus is write once, compile anywhere. So I've been working on a few projects that unfortunately make that philosophy a bit of a stretch (polite term). Programs written and compiled under windows didn't even compile properly on a Pi or Beagle. The thing about fpcupdeluxe is that it's an interface that lets you choose a specific version of both FPC and Lazarus. For example, "sudo apt install lazarus" gets version 1.6.7 I believe. But when you install it for a windows PC you get 2.0.10. With the fpcupdeluxe I was able to get and build that specific version for both the Beagle and the Pi. After that, since the libraries now matched, the applications compiled and ran. Although still not exactly the same. Graphical components appear to have an issue. What works on Windows doesn't work correctly on the Beagle or Pi. So I tried it on the LinuxCNC pc with rev 1.6.7. Same problem there so it's an issue with an object descended from TGraphicControl. TjdSevenSegDisplay = class(TGraphicControl)... Note in the photo when the component rectangle on which the segments are placed is dragged away from the 0,0 corner the segments don't come with nor do they resize correctly when the rectangle is expanded. On windows it works perfectly. On Linux it doesn't. The 6 digit display doesn’t have the problem so I'm on track for trying to figure out what's different at the base level of the component design. cid:image001.png@01D73BB9.185437C0 Anyway, that's why I want to be able to install the same version on full sized Linux system since I can't break the component on the WIN-7 or WIN-10 PCs and it takes way to long using a Pi or Beagle as the working desktop PC to do anything. And in the long run one of my goals is to develop some graphical based tools that run on Windows and LinuxCNC for machine control with CAN bus. That the sockets.pp interface for Lazarus is behind the sockets.c is another issue with socketCAN not yet supported by Lazarus.
