Now I am having problems installing Lazarus 2.2.4 on Linux systems where older

use (3.0.4 vs 3.2.2).
You can install several fpc on Linux.
** But you need to remove the global /etc/fpc.cfg and have it local to
the install. **
You can look at the output of
fpc -va empty_project.pas | grep fpc.cfg
to find the locations were fpc looks for it.
There may also be a way (I don't know) to have the IDE pass a param to
fpc telling fpc which fpc.cfg to use....
And you either need to start the IDE via a script, setting a suitable
%PATH env, so the correct fpc can be found. And fpc can find the correct
ppc.
Or if you don't cross compile, you can invoke ppc directly .
I use the below. It allows several builds, even of the same version
(debug / opt)
#!/bin/sh
mkdir -p /home/m/fpc/$INSTSRC
mkdir -p /home/m/fpc/$INSTSRC/source
cd /home/m/fpc/$INSTSRC/source
git -C /home/m/fpc/svn/source --work-tree=/home/m/fpc/$INSTSRC/source
restore .
### have a full working fpc in path to start the build
mkdir -p /home/m/fpc/$INSTPATH/
mkdir -p /home/m/fpc/$INSTPATH/def
cd /home/m/fpc/$INSTSRC/source
make clean
make all OPT="-g- -gl -O-2 "
make install INSTALL_PREFIX=/home/m/fpc/$INSTPATH/def
mkdir -p /home/m/fpc/$INSTPATH/def/lib/fpc/etc
mkdir -p /home/m/fpc/$INSTPATH/def/etc
cd /home/m/fpc/$INSTPATH
def/bin/fpcmkcfg -d basepath=/home/m/fpc/$INSTPATH/def/lib/fpc/$INSTVERS
> def/lib/fpc/etc/fpc.cfg
def/bin/fpcmkcfg -d basepath=/home/m/fpc/$INSTPATH/def/lib/fpc/$INSTVERS
> def/etc/fpc.cfg
ln -s /home/m/fpc/$INSTPATH/def/lib/fpc/$INSTVERS/ppcx64
/home/m/fpc/$INSTPATH/def/bin/ppcx64
## use in the IDE /home/m/fpc/$INSTPATH/def/lib/fpc/$INSTVERS/ppcx64
And another question:
How can I force Lazarus to show the initial configuration page, which is shown
on the very first start after installing Lazarus and later is skipped?
lazarus --setup
In the git main version of lazarus you can also force certain checks to
be skipped (including fppkg)
lazarus --help
--skip-checks=LazarusDir,FpcExe,FpcSrc,Make,Debbugger,Fppkg,Setup,MissingPackageFile,InstallDir,SingleInstance,All
Skip selected checks at startup.
You can put those into the
lazarus.cfg
file (in the same directory as your lazarus exe // or your startlazarus
exe, in case you use that and your lazarus is it the primary conf path)
