If you use lazarus trunk svn head,with fpc trunk, you must use fpc

So, if you update lazarus and compilation fails with fpc 2.5.1, you
must update fpc too.

Just as a note, sometimes there can be additional problems with
compiling FPC/Lazarus from SVN.
In both the case of FPC and Lazarus, sometimes a file or two gets moved
between directories in the SVN directory tree and when someone does a
"make clean..." after an "svn update..." the clean will not remove the
older one from the install "units" directory and that can cause problems
with future compiles, rebuilds.
Sometimes I got "checksum changed" error in a file at rebuild, sometimes
packages did not compile, sometimes the rebuild did not find things, etc.
I just had this problem a few days ago when after 2-3 months I updated
my FPC and Lazarus SVN from the trunk and tried to recompile both.
1. First of all I had to delete the target directories of the installed
versions of FPC and Lazarus ("make clean" should do this but since the
moved file is now in a new directory, it tries to delete it from the new
place instead of from the old place therefore leaving the old one there)
2. Then I deleted all SVN checkouts for both FPC and Lazarus and checked
them out again into a clean directory
3. I used the last stable FPC version to compile the new FPC trunk first
(sometimes you can not successfully compile the latest FPC 2.5.1 with a
one or two months old FPC 2.5.1)
4. Then I could compile the latest SVN FPC again with itself (compiled a
2.5.1 with a 2.5.1 made by a 2.4.x....confused enough yet?)
5. Checked out Lazarus from SVN into a clean dir and built it, installed it
6. Removed the Lazarus settings directory before 1st start and then
tested a rebuild from within Lazarus after setting the FPC dir in the
environment menu. If this works without a problem, you can start adding
the packages you use.
7. I had a problem with the latest stable Zeos 6.6.6 because it did not
compile. After looking it up on the net, I found the necessary changes
needed for Zeos to compile (changes were needed in one of the source
files, ZClasses.pas) under FPC 2.5.1.
After a few hours I had a newly working FPC/Lazarus installation.
This all is not for the faint heart... but can be done.
