Hi
If you download FPC and source, then I think it can be done.
I have tried to do this test program on my Pi.
Below is a description of the installation of Lazarus, you can skip the lazarus
part.

Program Test1;
{$RANGECHECKS ON}
{$OVERFLOWCHECKS ON}
{$S+ STACK CHECKING ON}
{$SMARTLINK ON}
{$TYPEINFO ON}
{$LONGSTRINGS ON}
{$VARSTRINGCHECKS Off}
Uses
cthreads,
classes,
sysutils,
PtcMouse,
PtcCrt,
PtcGraph;
Begin
Writeln('Test');
End.
Compiled with
/pp/Fpc/bin/fpc -gl -XX -FU"Ppu" -Fu"/pp/fpcsrc/packages/graph/src/ptcgraph"

This is done on a Pi

If you want the newest Lazarus IDE on a PI, do the following (I use Midnight
Commander on the Pi (sudo apt-get -y install mc) when unpacking tgz files etc).
1. Download FPC for Pi (Everything in 1 big package for eabihf ABI for
raspberry)<ftp://ftp.hu.freepascal.org/pub/fpc/dist/3.0.4/arm-linux/fpc-3.0.4.arm-linux-eabihf-raspberry.tar>
2. Download FPC source
(fpc-3.0.4.source.tar.gz)<ftp://ftp.hu.freepascal.org/pub/fpc/dist/3.0.4/source/fpc-3.0.4.source.tar.gz>
3. Download Lazarus source (lazarus-1.8.4.tar.gz) or
(lazarus-2.0.0.tar.gz)<https://sourceforge.net/projects/lazarus/files/Lazarus%20Zip%20_%20GZip/Lazarus%202.0.0/lazarus-2.0.0.tar.gz/download>
4. Create a folder /pp that belongs to the pi user and the pi group. (sudo
install -d -o pi -g pi -m 0770 /pp)
Install Fpc in /pp/fpc folder
Create a /pp/fpcsrc folder
Place the downloaded fpc source in /pp/fpcsrc
Create a /pp/lazarus
Place the downloaded lazarus source /pp/lazarus
5. Place the make-lazarus-first.sh script in /pp/lazarus
6. Run the make-lazarus-first.sh script
7. Place the make-lazarus.sh script in /pp/lazarus
8. Run the make-lazarus.sh script
9. Create link in /bin to fpcres (sudo ln -sf /pp/fpc/bin/fpcres
/bin/fpcres).
10. To create a Menu Programming short cut, go to
Menu -> Preferences-> Main Menu Editor
11. To create a Desktop short cut, place the text file "Lazarus" in the
folder "/home/pi/Desktop/"
