I just bought a new laptop and tring to set up Lazarus. The problem is installing ZeosDBO into Lazarus.

This is on Linux Mint/Mate 20.2 on an i5-1135G7

fpc -v

I am getting two errors when trying to compile and this seems to be the line it is complaining about:

TZFirebirdBaseDriver = class (TZAbstractPlainDriver, IZPlainDriver, IZInterbasePlainDriver)

    FIREBIRD_API : TZFIREBIRD_API;

I ran startlazarus as root and then did a

Package->Open Package File(lpk)

I then pointed it to ZeosDBO/packages/lazarus/zcomponent.lpk and clicked compile button. The file it is failing on is ZPlainFirebirdDriver.

Thanks for your attention.

This is the version of zeosdbo I have installed, both under windows and linux (I don't know if I should use any later or previous version, this one seems to be working fine for my projects):

[...] I ran startlazarus as root

ouch

Not recommended.

Well, how do you install something like ZeosDBO then? If the compile is successful, it is going to want to rebuild Lazarus and Lazarus is in a protected directory.

Terry

I don't understand what you are doing here. All I want is access to MariaDB. I beleive it is using mysql80conn.

Lazarus checks if the output folder is writable. If not, it creates instead a folder in your config directory.

I was just telling you the version I'm using and that compiles fine with lazarus 2.0.12/fpc 3.2.0
