[The original thread was in fpc-devel, but this is a lazarus issue I think]

I'm having difficulties compiling lazarus with this branch. First I tried with lazarus 1.8.4, now I'm trying with lazarus 2.0.

I compiled that branch, installed (make install), created a fpc.cfg with fpmkcfg, put the new compiler directory (d:\pp\bin\i386-win32) as the first one in PATH, cleaned everything in the lazarus directory (make clean and deleting all lib directories).

This is the result of make bigide

(3104) Compiling tadiagram.pas
D:\laz_test\components\tachart\tadiagram.pas(347,38) Error: (3349) Only static methods and static variables can be referenced through an object type tadiagram.pas(989) Fatal: (10026) There were 1 errors compiling module, stopping

make ide generates a lazarus binary, but then I cannot install my components:

VirtualTreeView (checked out from git)

VirtualTrees.pas(772,19) Error: No matching implementation for interface
method "SetData(const tagFORMATETC;var TagSTGMEDIUM;LongBool):LongInt;
StdCall;" found

OK, remove virtualtreeview (I don't need it in this project, after all this is just a test).

Next TAChart fails (wait, this is included with lazarus)

tadiagram.pas(347,38) Error: Only static methods and static variables
can be referenced through an object type

OK, remove it too and jcfidelazarus,turbopoweripro and laz_fpspreadsheet which require it.

Now I have a working ide (without those packages) and I can do some tests, but it worries me that there's no virtualtreeview and the tachart included with lazarus doesn't compile.

Sounds like this bug:

Please update your Laz-fixes installation: The patch for the issue with VirtualTreeView has been merged to fixes in r60091, that for the issue with TAChart in r60392.

I checked out r60392 but I still cannot compile VirtualTreeView (checked out from github
https://github.com/blikblum/VirtualTreeView-Lazarus.git, branch lazarus-master)

No, you must use the VirtualTreeViews which comes with Lazarus (folder components/virtualtreeview). If you absolutely want to stay with this github version you should replace "var" in the offending methods by a "const". I do not know, however, whether this version will cooperate with the Online-Package-Manager (you absolutely must uninstall the VTV of the Lazarus version!).  If that would not work you'd be forced to use the VTV of the Lazarus installation, or you switch to Lazarus trunk in which this version conflict is resolved.

Sorry to barge in here, but is this version actively maintained again? I distinctly remember from 2016 that it was extremely outdated and did not incorporate upstream many forks...

Actually, I don't care: if the version that comes with lazarus works that's fine for me. In fact I didn't even know that it was included, http://wiki.freepascal.org/VirtualTreeview seems to imply you have to get it from github.

Oh, I see now that it was *not* included in lazarus 1.8.4, that's why I originally used the version from lazarus-ccr and seeing that it wasn't compiling I tried the one from github.

I added a note to the wiki that both lclextensions and virtualtreeview are now included with lazarus.

Which article? I want to have a look and check whether it is correct. Because the situation is more complicated: In Laz trunk (or v2.2 in the future) all VTV files were renamed to have a "laz." prefix, and the registered components were renamed as TLaz* (e.g. TLazVirtualStringTree instead of TVirtualStringTree). This was made to avoid a naming conflict if a user wants to install older oder newer versions of VTV from git or somewhere else.
