Hi ,

I have already configured the Linux environment (Ubuntu 20.04 server) as explained in the documentation:

http://docwiki.embarcadero.com/RADStudio/Sydney/en/Linux_Application_Development#Installing_Development_Packages

If I try to compile standard console app or webbrocker Apache module compile fine.

Any help?

Thank you very much

Hi,

according to https://quality.embarcadero.com/browse/RSP-17811 , you should install zlib1g-dev package as
sudo apt-get install zlib1g-dev

Hi EvgenyK

If I compile a standard Apache module, I can compile fine. Same if I try to compile a simple console app.

When I try to compile a RO app Delphi raise the above exception

Thank you very much and best regards

Hi,

try to compile a simple console app that uses System.Zlib unit like

program aaa;
{$APPTYPE CONSOLE}
uses System.Zlib;
var
  k: z_stream;
begin
  deflate(k,0);
end.

will it be compiled correctly?

have you updated Linux SDK at Delphi IDE->Tools->Options->Deployment->SDK Manager after calling sudo apt-get install zlib1g-dev ?

Hi EvgenyK

no, not compile!

But I have installed the package and update linux SDK.

I have to investigate. Thanks for the support

Hi EvgenyK

After I dropped, reinstalled PAServer and reimported SDK all work fine!

sorry if I wasted your time!

Thank you very much for your support!
