Hi All,
 I had a version of lazarus 0.9.24 where my code was working on Redhat
4. We updated lazarus then began having issues. Now we have a clean
install of RedHat 5 with lazarus 0.9.26 and fpc version 2.2.2. I keep
getting these error messages attached and do not know how to resolve.
Your help is much appreciated.

Thanks,

Lefti

Lazarus 0.9.26 is not really a "New Version".
I joined the development ~ 3 years ago and then 0.9.28 was already
published.
You should try a more recent version. The development happens with
good speed although there are releases only seldom.
You would be positively surprised...

Hi,
 Yes I understand. The sysadmin mentioned that was the latest release
he could install without forcing an install and it was the cleanest.
Anyways I was able to get around the errors by removing the SQLQuery
from the .lfm file and putting it back in. Now I get an error
/usr/lib64/lazarus/components/sqldb/sqldblaz.pas(1,1) Fatal:Can't find
unit system used by SQLDBLaz

Any ideas?

Thanks

Lefti

One suggestion would be to get a virtual machine with a recent version
of RHEL/CentOS/whatever, and install a recent Lazarus version in it
(e.g. the just released 0.9.30.4 IIRC).

You can write your application in this and test it on the old Red Hat
machine.

This way, you get access to newer components, bug fixes, performance
improvements etc...

There have been quite a few, so a bit of pain in the development
process might save you a lot of pain in dealing with possible bugs in
your compiled executables...

You always could install Lazarus (and fpc) in your user directory.
Then you can upgrade to the latest release without help from an
administrator.
