TAChart error compiling old project

(1/2) > >>

Hello to all,
today I updated the sources from Gitlab, I recompiled Lazarus without errors.

I then recompiled a project that I had last compiled in June, without errors, but this time it reports these errors which I do not understand.

I am also attaching an image where you can see where the error is reported.

TAChartAxisUtils *IS* distributed along with the GitLab sources. Did you do a CLEAN rebuild of the IDE?

Moreover, the many "Duplicate file" warnings may indicate that you use path settings in your application which point into Lazarus units.

The IDEIntf package should not be required by your application because it depends on many parts of the IDE which are not available to your project. If you want to reuse some component editors in your application copy these sources into your project rather than adding IDEIntf to the required packages, or extending the search path by the path to components/ideintf. Then you are also free to make the required adjustments to remove IDE-dependent parts.

You can view from attached image, that when show the error, "TAChartAxisUtils" is opened in editor.

Hi, Mario

Please show the requirements of your project (the packages listed in the tree of the project inspector), and the paths that you set in the project options.

I've uploaded a screenshot of both.

I've added "$(LazarusDir)/components/ideintf" this morning in project options, because of another problem.

I've tried now on Windows, but i have same problem there.

Hi, Mario
