Can't install CEF3.3

[chiong]

I have the following error when compiling the code :

"cef3ref.pas(1578,1) Error: Local variables size exceeds supported limit"

Older release also generate the same error.  I am using lazarus 3.2.

Any help is much appreciated. TQ.

fpCEF3 - has been unsupported for years. Install CEF4Delphi, which works very well with Lazrus: https://github.com/salvadordf/CEF4Delphi/releases/tag/131.0.6778.265

Thks
can you give us some clues how to install it pls ?
Online Package Manager returns an error :
'One or more packages can't be found. See the package graph for details'

Then I followed your instructions :
https://github.com/salvadordf/CEF4Delphi/wiki/Installation-in-Lazarus-FPC

but still same error msg

Lazarus 3.8
FPC 3.2.2

1. install DCPcrypt if you don't already have it installed - in Lazarus IDE:
    a. Package > Online Package Manager
    b. select the DCPcrypt package.
    c. click Install.
    d. rebuild the IDE
2. download the CEF4Delphi package from: https://github.com/salvadordf/CEF4Delphi/archive/refs/tags/131.0.6778.265.zip
3. unzip the file
4. rename the unzipped folder to: CEF4Delphi
5. create a new folder _components in the Lazarus installation folder, e.g. C:\Lazarus
6. move the CEF4Delphi folder to C:\Lazarus\_components
7. launch the Lazarus IDE
8. package > Open package file
9. select: C:\Lazarus\_components\CEF4Delphi\packages\cef4delphi_lazarus.lpk
10. click Compile.
11 Click Use > Install.
12. rebuild the IDE

1. install DCPcrypt

Huh? I am not sure current DCPcrypt supports tls 1.3 and since when?
If it does I am amazed, if it does not it makes the whole thing useless.


can you plz shed some light Pawel?

[bbd666]

Then I tried to run the demos in the folder Lazarus_windows.
But they don't work :

CEF binaries missing !
the missing files are :
libcef.dll
chrome_elf.dll
d3dcompiler_47.dll

etc... around 60 files more

@Thaddy : what do you mean "whole thing" ? Impossible to use it with Laz 3.8 ?

[Thaddy]

No I mean that the proper encryption protocols are not present in dcpcrypt, which means any software that relies on it is useless: I am not aware that dcpcrypt supports tls 1.3. If it does, that is a pleasant surprise. I thought it was abandon ware.

Note that if something compiles, it does not mean it is usable, especially not where security is concerned. And with CEF that is most certainly the case. Btw you don't need to install cef unless you are a screen drawer. You just need the package.

I dont' think dcpcrypt is used to do any connection with internet... maybe is used to do something else.

Chromium must be the one that access internet with their libs internally.

Silly you: https

Encryption is core for internet and dcpcrypt used to provide that, similar to openssl.
I merely think that dcpcrypt is unloved and not maintained, which makes it useless as an openssl substitude.

For such a good fpc programmer as you are, that remark comes to me as a shck because it is soooooo wrong.

Hence I wrote :"pleasantly surprised"... If the current bottom line is supported, which is tls 1.2.

[bbd666]

ok . what about the demos of the package ?

Again. I said that dcpcrypt maybe is used for something else.

Why chromium will need dcpcrypt? It has no sense.

If course https will be accessible with chromium and his own libraries. No need for third-party.

@Thaddy - If you read the package's documentation, you'd see that it requires DCPcrypt to work:

CEF4Delphi is available in Online Package Manager but you will need to install the DCPCrypt package first.

@bbd666: Here you have links to download the necessary files: https://github.com/salvadordf/CEF4Delphi/blob/master/README.md
and here instructions on how to properly place them in the program directory: https://www.briskbard.com/index.php?lang=en&pageid=cef

I think that was clear. But we don't know why is that required. For what is used.

It seems that DCPcrypt is only used to determine the SHA256 hash:
https://github.com/salvadordf/CEF4Delphi/blob/f0f4de8b3b5e69d0b9353a374093959712c56bb2/source/uCEFOAuth2Helper.pas#L121
So it can be replaced by analogous functions from FCL.
