Raspbian Buster (based on Debian 10 Buster) has FPC and Lazarus available in the repositories, but they suffer from the same "design decisions" that don't allow for a nice experience, namely the smooth IDE rebuilding capability based on source packages that is possible with FPC/Lazarus official .deb packages vs the crippled experience with the official Debian/Raspbian packages. One wishes there were official FPC/Lazarus packages for Raspbian as there are for Intel Debian/Ubuntu, which are also frequently updated; not being that the case (at least for now), this page shows the steps for building your own FPC, FPC-source and Lazarus packages for Raspbian. Example shows steps for Lazarus 2.0.4 which includes FPC 3.0.4, most recent at the time of writing. Adjust accordingly.
Requirements:
- Raspberry Pi 4 Model B, 4 GB (less memory models would require swap)
- Latest Raspbian Buster fully updated
Steps:
- Install subversion:
sudo apt install subversion - Get bootstrap FPC compiler. The latest compiler is compiled with the previous version of itself.
- Extract compiler. This will create a
fpc-3.0.2.arm-linuxdirectory. - In this directory, as pi user, run
./install.sh - At the four prompts, answer
Enter, n, n, n: this is, accept suggested directory/home/pi/fpc-3.0.2, no Textmode IDE, no documentation, no demos. Ignoretarwarnings. Note the additional files written to/home/pi:.fpc.cfg,.config/fppkg.cfg,.fppkg/config/default. When the build is done, to delete this temporary bootstrap compiler these files and the/home/pi/fpc-3.0.2install directory need to be deleted. - Temporarily add FPC install directory to PATH:
export PATH=$PATH:$HOME/fpc-3.0.2/bin. If you have to reboot for any reason before completing the FPC build, you have to do this step again. - Test if all ok:
fpc abcd. This invokes the just installed compiler trying to compile a non-existent file (abcd). A multiline message will be shown including the compiler version. - Non-step note: the following steps are mostly based on this
- Install development libraries:
sudo apt install libgtk2.0-dev libgpm-dev libncurses-dev mkdir ~/pascalcd ~/pascalsvn co https://svn.freepascal.org/svn/fpc/tags/release_3_0_4 fpc, you have to be online for this and the next step to work.svn co https://svn.freepascal.org/svn/lazarus/tags/lazarus_2_0_4 lazaruscd lazarus/tools/install- Edit
create_fpc_deb.sh, look for line with the following content:arm) ppcbin=arm; FPCArch=arm;;, (currently line 109). Copy and paste this line below itself, so it will appear twice. Edit this copy to read like this:armhf) ppcbin=arm; FPCArch=arm;; ./create_fpc_deb.sh fpc ~/pascal/fpc/. This will compile the latest compiler with the bootstrap compiler. It takes about 13 minutes; after the first 10 minutes the CPU starts throttling. A.debfile will be created, in this example it ended up beingfpc-laz_3.0.4-190826_armhf.deb; the exact name will be show at the end of the compilation.- You have completed the FPC build. Reboot the Pi to get rid of the temporary PATH.
- Uninstall the bootstrap FPC:
rm -rf ~/.fpc.cfg ~/.config/fppkg.cfg ~/.fppkg ~/fpc-3.0.2 - Install the just created FPC Debian package:
sudo dpkg -i ~/pascal/lazarus/tools/install/fpc-laz_3.0.4-190826_armhf.deb
