Could not compile the VirtualTrees components with RAD Studio 10.3 Rio and 10.4 Sydney

[Jeanmilost]

Hello,

Compiling the VirtualTrees components with RAD Studio 10.3 Rio and 10.4 Sydney, I faced the following issues:

In 10.3 Rio, I needed to add the following include in VirtualTrees.Header.pas:
{$IF CompilerVersion >= 33} System.Generics.Collections, {$IFEND}

In 10.4 Sydney, I needed to modify the VirtualTreesD.dpk in the following manner:
{$LIBSUFFIX AUTO} => {$LIBSUFFIX '270'}

and modify the VirtualTreesD.dproj in the following manner:
<DllSuffix>$(Auto)</DllSuffix> => <DllSuffix>270</DllSuffix>

Can you please fix that?

Regards

I added System.Generics.Collections to the uses of the unit VirtualTrees.Header.

10.4 Sydney officially supports {$LIBSUFFIX AUTO} and I cannot see a problem under 10.4.2. Please include the exact version number and more detailed repro steps.

My current version is: Embarcadero® RAD Studio 10.4 Version 27.0.37889.9797

I have also the following third-party installed products:

• GExperts (experimental)
• CnPack IDE Wizards 1.2.0.1035

My Windows version is: Windows 10 Professional (Version 10.0, Build 19043, 64-bit edition)

I not used any particular protocol, I just opened the VirtualTreeView.groupproj in my RAD Studio application, I changed the build configuration to Release and the target platforms to Windows 32-bit in the both projects, I built the VirtualTreesR270.bpl one, and I tried to install the VirtualTreesDS(Auto).bpl one. This gave me the following error:
[Fatal Error] Can't load package VirtualTreesD$(Auto).bpl. The system cannot find the file specified

And I applied the above described process to fix that issue.

About the 10.3 Rio issue, I failed to compile the project until I added the above mentioned include. I got several errors saying me that several objects were not declared. I added an ifdef because I had no issues with the previous versions I tested, which were: XE7, XE8, 10.0 Seattle, 10.1 Berlin and 10.2 Tokyo. I have all these compilers installed side by side on my working computer, plus 10.3 Rio and 10.4 Sydney, for your info.

Well, it doesn't make much sense that it compiles in 10.4 and 10.2 and before, but fails for 10.3. But since I have no 10.3 for testing at hand, I added this uses, which should be uncritical even if not used. I generally avoid $IFDEFs if possible.

My current version is: Embarcadero® RAD Studio 10.4 Version 27.0.37889.9797

In this version {$LIBSUFFIX AUTO} seems to be buggy, updating to 10.4.2 should solve the problem for you.

Ok, thank you very much
