Lazarus cannot find IdMessageBuilder unit

[Wai-kit]

I have found this excellent article https://www.indyproject.org/2008/01/16/new-html-message-builder-class/ on how to send an email in HTML.

I have added IdMessageBuilder unit to my uses clause.
Although I have indylaz.lpk package (v 10.6.2) installed, I get this error: 'Cannot find IdMessageBuilder used by...' when I try to compile.
Does somebody know what the problem is and how do I fix this?

Cheers,
Wai

Are you installing Indy manually by compiling indylaz directly? Or are you installing Indy by using Lazarus' OPM?  If you are not installing by OPM, I suggest you try that instead.  Otherwise, you probably just don't have your search paths configured properly so the compiler can find Indy's source files.

I have installed these 3 ways:
1. fpcupdeluxe
2. manual
3. OPM

None of them fixed the problem.

Since indylaz.lpk installed without errors, I think that my search paths are configured correctly. All the design-time components
are available in the component palette.

I believe this is a bug in the lazarus package system. It happened before, unfortunately nobody knows why.
As a quick fix, just add IdMessageBuilder to indylaz.lpk, rebuild the package, then your project.

Did you add the IndyLaz package as a dependency to your project?

That solved the issue. Thanks.
