Solved: Error when compiling Zeos on Delphi 12

[Prometeus]

Hello,

According to the attached picture, I am getting an error when compiling the 'Delphi 12' package from subversion '8051'. I think it's related to some compiling version issue, but I could not find the 'inc' file that probably needs fixing. Any tip on this?

Thanks!

Hello aehimself,

Thanks for the info!

For some reason I received this message when I tried to read your link: "You are not authorised to read this forum."

Long story short, the issue is caused by the weak NativeInt alias introduced in Delphi 12 and the proposed solution is available as a pull request on GitHub :)

With the current fixes the first errors were gone but it failed with this error:

[dcc32 Error] ZDbcODBCStatement.pas(1961): E2251 Ambiguous overloaded call to 'Max'
ZCompatibility.pas(841): Related method: function Max(const NativeUInt; const NativeUInt): NativeUInt;
System.Math.pas(5172): Related method: function Max(const Cardinal; const Cardinal): Cardinal;

When I changed the call on line '1961' from 'Max' to 'System.Math.Max' or 'ZCompatibility.Max' it compiled without errors and installed correctly.

That modification is in the pull request as well. The "ZCompatibility." prefix mefore Max is included if NATIVEINT_WEAK_REFERENCE is defined.
Same had to be done in ZDbcOracleUtils : 1433, ZDbcInterbaseFirebirdMetaData : 2000 and ZAbstractRODataSet : 9417 as well.
