we can not compile the CEF3 package in Windows 10 FPC version 3.3.1 (SVN 59585M) - FPC stack overflow

[Steve--W]

---

I reported this to FPC bug team and they said..............................

The compiler produces an error: cef3ref.pas(1577,1) Error: Local variables size exceeds supported limit."That is stack size.

It works ok reducing array size -2 in cef3types.pasTCefRectArray = array[0..(High(Integer) div SizeOf(TCefRect)) - 2] of TCefRect;

Somebody should add a PCefRectArray = ^TCefRectArray type definition and use that instead of abusing the stack.EDIT : So no FPC issue, fix it in the upstream.

---

The details to reproduce the problem are...........................................

Use fpcupdeluxe (i386-win32) to install Lazarus version 2.1.0, with FPC version 3.3.1 (SVN 59585M)

Download FPCEF3 (version 3.3029.1) and try to install in Lazarus by selecting cef3.lpk in the "Package/Open Package File" menu then select compile......

The compile fails with error: cef3ref.pas(1577,1) Error: Local variables size exceeds supported limit.

The code snippet this error points to is .......
procedure TCefBrowserHostRef.ImeSetComposition(const Atext:ustring; underlinesCount: TSize; underlines: TCefCompositionUnderlineArray; const
replacementRange, selectionRange: TCefRange);
Var
t: TCefString;
(line 1577:) begin
t := CefString(Atext);
PCefBrowserHost(fData)^.ime_set_composition(fData, @t,underlinesCount,@underlines,@replacementRange, @selectionRange);
end;

This is still an issue.

Following this guide: https://lazplanet.blogspot.com/2015/09/create-web-browser-in-3-minutes-using.html
used tortoisesvn to download.

tried reducing array size -2 in cef3types.pas
TCefRectArray = array[0..(High(Integer) div SizeOf(TCefRect)) - 2] of TCefRect;
Then tried compile again, didnt fix for me.

"Somebody should add a PCefRectArray = ^TCefRectArray type definition and use that instead of abusing the stack.
EDIT : So no FPC issue, fix it in the upstream." - I wish I understood this :(

Maybe I'll stick with gecko.

Any other workaround suggestions?

Hi I reported the problem originally and when it did not get fixed I moved to using salvadordf/CEF4Delphi | | | | | | | | | | | salvadordf/CEF4Delphi CEF4Delphi is an open source project to embed Chromium-based browsers in applications made with Delphi or Lazaru... | | | This has worked fine for me.

Gave up and had no issues installing CEF4Delphi. I'll get busy reading up how to implement, many thanks Steve.
