Zcomponent missing (Lazarus 1.4)
« on: May 03, 2015, 12:13:12 pm »
After uninstalling Lazarus 1.2.6, and cleaning the Lazarus directory, I installed Lazarus 1.4.
When opening Lazarus after this installation, the message
Quote
"Unable to open the package "zcomponent",
This package was marked for installation."
What should I do to get zcomponent installed?

Should the zeos controls be in the install, or is it a separate download?
Zcomponent is needed for LazReport (lr_zeosdb.lpk), but not included.

As the name suggests it is a package that adds support for the zeos components in to lazreport. If you are not using zeos components there is no reason to install it and if you do use them then you already have them installed and no problem will arise from using it. So no lazreport should not share zeos components but they should stop sharing the zeos support for lazreport and donate it to zeos components instead.

Hello, pls can you help with a guide on how to install the zcomponent, see what i did below.

I downloaded the zcomponent zip from Sourceforge
2. extracted the Lazarus folder to Lazarus/components/zcomponent
3. i opened the lpk file in Lazarus to compile and got some errors, see attached picture

The ZEOS component consists of several packages, and when you install zcomponents.lpk first the IDE does not know where the others are.

In "Packages" > "Open Package file", open first zcore.lpk, then zplain.lpk, then zparsesql.lpk, then zdbc.lpk - just "open", no need to "compile" nor "install". Finally open zcomponent.lpk and select "use" > "install". Now it should work.

The easier way is to use the Online-Package-Manager (in menu "Package"): scroll down the list, check ZeosDBO, click Install and answer the few questions. Wait until the IDE is rebuilt.

You will get version 7.2.14 of ZEOS this way. If you need the latest development version (some v8.x) you must do the steps as described above.
Mainly Lazarus trunk / fpc 3.2.0 / all 32-bit on Win-10, but many more...

What is your Lazarus/FPC version? You seem to be on Windows, aren't you?

Recent versions of Lazarus has Online Package Manager, which will help you install packages easily:
Lazarus main menu > Package > Online Package Manager
