Lazarus cannot find IdMessageBuilder unit
lazarus / 38-Networking and Web Programming

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.
