Zeoslib Portal

Hello, I'm new to the forum. In the Lazarus forum I was given the tip to try it here.
I have the problem that zeos 8 cannot be installed with fpcupdeluxe in the current Lazarus Trunk.
I get the error message: Identifier idents no member VUInt32. See attached screenshot.

Many thanks for help

Hello zeosbow,

welcome to the forums

You seem to use FPC trunk for compilation. We don't support FPC trunk because it is a moving target. The problem in this case is that they added a variant type (varUInt32) but didn't extend the TVarData record accordingly. I created a ticket to see if they will add TVarData.VUInt32:
https://gitlab.com/freepascal.org/fpc/s ... sues/40729

Zeos is only supported on FPC 3.0 and 3.2. The Lazarus version should not matter too much. It should be possible to use trunk there.

Best regards,

Jan

It seem sthe problem was fixed upstream (Commit 886f91de). Unfortunately I cannot get Lazarus and FPC to build in their trunk versions so I cannot test easily.

Many thanks for your efforts,

I have downloaded the modified file "varianth.inc" and copied it into the folder fpcsrc\rtl\inc. Previously renamed the old file to varianth_alt.inc.
Then tried to compile zeos. Unfortunately without success. VUInt32 is still not recognised. Tomorrow I will rebuild Lazarus Trunk and try again.

I thought that zeos only supports the stable freepascal compilers.

I have a trunk with zeos 8 running on one computer. I wanted to move my project to another computer and thought: Install a new trunk with new zeos.

I wish I had kept my hands off it...

Hello,
after I rebuilt Lazarus Trunk with fpcupdeluxe I was able to install zeos 8 with fpcupdeluxe, hooray!!!
Thanks again for your efforts!
