Hello,

i use Delphi7 Enterprise with UniDac 4.3.8.
When compiling I get errors of the Zlib when DBAccess is involved:
[Error] ZLib.pas(237): Unsatisfied forward or external declaration: '_tr_tally'
[Error] ZLib.pas(238): Unsatisfied forward or external declaration: '_tr_flush_block'
... and so one.

What can i do to fix the problem?

Thanks
Thoren

Hello,

Such error occurs when you have another (maybe third-party) ZLib units. UniDAC uses ZLib that is supplied with Delphi. Please check that Delphi Library path does not contain a path to another ZLib units.

Hello,

hmmm.. i use zipmaster.
Unidac and zipmaster can not use together?

UniDAC uses ZLib units supplied with Delphi, so UniDAC is compatible with any other components that use these units.
If zipmaster uses its own ZLIb units, it means that it is not compatible with any other components that use ZLib units supplied with Delphi.
