I'm trying to install the most recent version of FPC/Lazarus readily
available for the Raspberry.  That seems to be 3.0.0 and 1.6.2 per

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
https://www.tweaking4all.com/hardware/raspberry-pi/install-lazarus-
pascal-on-raspberry-pi-2/
The install completes but on running Lazarus after the install the IDE
can't find the "FPC sources."  The attachment shows the window I get
at startup.  Any ideas on how to look for the sources?

thanks.

You can see from the comment that it needs the file
rtl/linux/system.pp that you need to provide the directory ABOVE the
rtl directory.

You provided /home/pi/dev/fpc/3.0.0/rtl
but you need to enter /home/pi/dev/fpc/3.0.0

You can try most recent version or trunk/trunk with fpcupdeluxe. I
don't increase swap file, but use zram. Compile time is  faster then
swap (sdcard speed is slower then ram/zip).
You can watch this video and speed increase when compiling qt5.

I use fpcupdeluxe, trunk/trink, mORMot trunk. Adding packages and
rebuld Lazarus without problem.

The most recent versions are laz and fpc trunk and will happily build
on a Raspberry Pi. (written from a Raspberry Pi) with  a bootstrap fpc
3 from stretch.

Brilliant!

rvk - That worked!  I have to say I don't get that info from the
graphic I posted but... I'm not being truculent here:  I don't see how
that follows from the graphic I posted.  It's probably really stupid
but could you point it out to me?  (for future reference)  Thanks.

Others - all good info I may try.  I'm trying to build a new app that
moves between Linux and Windows.  Compiler versioning isn't
necessarily crucial (depending on implementation) but it is definitely
preferred.

that dialog asks:
QuoteThe sources are required for browsing and code completion.
For example it has the file 'rtl/linux/system.pp'.You see that the
file system.pp includes the path rtl/linux.
So when you look at the perspective of /home/pi/dec/fpc/3.0.0/ you can
paste rtl/linux/system.pp after it and you come to a valid file.

If you however give /home/pi/dev/fpc/3.0.0/rtl/ as path you get
/home/pi/dec/fpc/3.0.0/rtl/rtl/linux/system.pp. Notice the double
rtl/rtl/. That doesn't point to a valid file.

So if the question is "give a directory/path which should have the
file dir1/dir2/file1.txt" you should point to the directory which
contains that dir1 (and after that dir1 contains dir2 and dir2
contains file1.txt).

Thanks for the explanation rvk.  That is completely counter intuitive
to me...which means I'll have to keep my eyes open for that sort of
explanation.  Thanks again.
