Now you can start 2 instances of lazarus, with a different setting for the
compiler version.

I have 4 or 5 such versions.

Thanks, that seems simple enough. :)

It is.


Just a follow-up:
After downloading the 3.2.0 sources via svn I went into the new 3.2.0
dir and did (I am using an RPi4 computer with 4GB RAM):

$ time make all FPC=/home/pi/bin/ppcarm OPT=-dFPC_ARMHF

So I did not do a "make install"...

I also did:
$ cp .lazarus_2.0.8 ./.lazarus_2.0.8_3.2

Is the above OK for using the compiler as outlined above pointing the
shortcut to to the new dir as you outlined?

You need to do the "make install". How else will the compiler find the units when compiling ?


Beware though!!!!
-----------------
I have fallen into the trap of copying the pcp dir when installing a
new version of Lazarus before. Then unbeknown to me Lazarua used
installed components where the paths pointed to the *previous*
version.
That resulted in both Lazarus versions sharing the exact same files
including generated binaries....

This is so, but it does not have to be a problem: you must not recompile
lazarus itself using such a secondary copy.

I only recompile lazarus using the configuration with the official released FPC.
