Hi,

What is a recommend setup so I can easily switch between the 2.0.2 and 2.0.x and 2.1.1 versions for testing fixes/changes and what impact they would have on my applications.

I just got a confirmation from Mantis that one of the bugs I reported has been fixed in 2.0.x and a fix and possible speed increase change have been made in 2.1.1 and if I could test 2.1.1. How do I go about such a setup. I don't want to remove 2.0.2 and I use it for our commercial development work.

I am currently running on GNU/Linux and have 2.0.2 installed in /opt/fpc

Regards,

Simply install them in different directories. I often just use -n and use -Fu on the command line to point the compiler to the right rtl. If this is to uncomfortable, you can make the configuration file conditional, it supports #ifdef constructions (check documentation).

If you upgrade from svn, just do 'make install', then 2.0.x will be placed in /usr/local/lib/fpc/2.0.x and 2.1.x in /usr/local/lib/fpc/2.1.1

Change your fpc.cfg to use $fpcversion instead of 2.x.x

And make two symlinks in /usr/bin, one which is called ppc386_2_1_x and one which is called ppc386_2_0_x.

This makes upgrading very easy for both (make install) and you can choose your compiler-version with choosing the right name. (I also have a 'default' ppc386 link, which in my case is 2.1.1

This sounds like a easy way or doing it, thanks!
Can one change the installation path with the "make install" command? I could never figure this out, so always did a "make zipinstall" and then unpack it to my desired location. I prefer the /opt path as that is where my Lazarus install lives.

If you name them ppc386-2.1.1 and ppc386-2.0.2, then iirc you can choose
which one you want per compile;

fpc -V2.1.1 compileme.pp

or

fpc -V2.0.2 compileme.pp

Thanks to everybody that helped. I managed to setup 3 versions of FPC in my home directory and changed the fpc.cfg file to use the $fpcversion instead of a hardcoded version. All works perfectly.

All these tips should be place in a FAQ or WIKI somewhere if it hasn't already!
