Hi

Does the "Project Options | Version Information" have any affect under Linux? I noticed it created a <projectname>.rc file, but does it actually include something in the Elf executable or anywhere else for that matter? Can the desktop environment check it, or the application itself at runtime etc..?

The reason I ask, is because the wiki conveniently ignored that tabs help in the IDE help page.

Did anyone find an answer for this? I'm interested because I would like to extract the version information at runtime in both linux and in windows?

So would I, but nobody responded yet.

Also, if the ELF format doesn't support version information, then shouldn't the Version Info tab in Lazarus IDE be disabled for Linux, BSD platforms. There is no point in giving the developer false hope by filling in that information, but nothing is inserted in the executable.

As for extracting the version information from the executable under Windows and Linux.
I thought of writing some wrapper function for this. Under Windows that function will use the Windows API, and under Linux it will use '<executable> --version' and read back the result. Even though you create a Linux GUI application, under linux the stdout is always available, so it should work (I think).

The other question I have, is the application icon. Does the ELF format support a built-in application icon? Can Gnome or KDE see that icon inside the executable (like Windows does) when you create a desktop shortcut, or must you always use and external icon image file.

Version 2.3.1 of the compiler supports all this on linux.

Michael.

It should not be disabled. Project options don't depend on the current target OS, so if you current target OS doesn't mean you are not allowed to set the version number, because later you (or somebody else) may decide to compile the application for windows. The manifest option and the application bundle option are not disabled either on linux.

If the compiler supports it, how can the information be extracted at runtime?

There are calls in the system unit to get the resource data; I have not yet documented them.

Look for FindResource, FIndResourceEx etc. in rtl/inc/sysres.inc

Excellent news. Thanks Michael.

Point taken. I can see how this could be useful for multi-platform projects.

Is it correct that these are not implemented yet (along with no documentation)?

All functions in the resourcemanager seems to return 0 (nul). I'm using revision 13233 from the fpc trunk repository.

uses FileInfo;
var info:TFileVersionInfo;
begin
  info := TFileVersionInfo.Create(nil);
  info.fileName:=Application.Params[0];
  showmessage(info.VersionStrings.Text);
end;

Works for me under Windows.

Note that the Lazarus IDE does not pass this information to the compiler, if the target is not win32 (or win64?). You would have to do that yourself.
