[hawkeye]

When tried to installing Zeos 7.0.3 stable on lazarus 0.9.30.4 it show warning :

hawkeye,

have a look to http://zeos.firmos.at/viewtopic.php?t=3662

[hawkeye]

I had tried to compile the first (zcore) from five lpk that must compile manually
- http://zeos.firmos.at/viewtopic.php?t=3662
- http://zeos.firmos.at/viewtopic.php?p=16767#16767
but its not working

/usr/lib/lazarus/0.9.30.4/components/ZEOSDBO-7.0.3-stable/src/core/ZEncoding.pas(604,37) Error: Identifier not found "CP852ToUTF8"

And beside that it marks on

852: //CP852
begin
DbcConvert := @CP852ToUTF8;
PlainConvert := @UTF8ToCP852;
end;

on ZEncoding.pas
Its on ubuntu 12.04

hawkeye,

hmpf now i know what's wrong ))): It seems the unit LConvEncoding of LCL misses these two functions in your current LCL version.

Three suggestions:
- Update you Lazarus
- Comment the whole case for Codepage 852
- comment the WITH_LCONVENCODING define in ZeosLazarus.inc

I hope it helps..

Edit: Is theire a way to check the LCL version? So we can handle this case...

[hawkeye]

Frankly i don't know how to check LCL version but after i tried to comment Codepage 852 i didn't find some error anymore but even after restarting lazarus i still can't find Zeos component in the pallete

Edit :
I saw on the package graph under Loaded Packages-->ZComponent 7.0.3 it used LCL 1.0.

hawkeye,

Open all Z* packages and compile them again. Then recompile Lazarus. That should solve the remaining issue.

Concerning the issue, i'll add a define around. It might be better to have a LCL version check to prevent a looping thread.

[SOLVED]
Finally after upgrade to Lazarus 1.0.4 manually (because ubuntu software centre provide only 0.9.30.2) and comment on Codepage 852, it solved

Thanks Egon

hawkeye,

Thanks for confirmation. But this issue can become a never ending story, i think. So i'll add a define around to avoid such threats in future..
