Link error with build 3770

[naoki5]

https://bitbucket.org/chromiumembedded/ ... ckStart.md
We have built CEF from source code referring to this page.
The branch is 3770.

My environment is
Windows 10 Pro 64bit (1809) Japanese
Visual Studio 2017 Version 15.9.13
Windows SDK Version 10.0.17763.0

The contents of the .bat file are as follows:

update.bat
set GN_DEFINES=proprietary_codecs=true ffmpeg_branding=Chrome is_official_build=true
set GN_ARGUMENTS=--ide=vs2017 --sln=cef --filters=//cef/*
python ..\automate\automate-git.py --download-dir=c:\code\chromium_git --depot-tools-dir=c:\code\depot_tools --no-distrib --no-build --branch=3770 --force-clean --force-update

create.bat
set GN_DEFINES=proprietary_codecs=true ffmpeg_branding=Chrome is_official_build=true
set GN_ARGUMENTS=--ide=vs2017 --sln=cef --filters=//cef/*
call cef_create_projects.bat

Finally, I built "Release_GN_x86" using Ninja.
The build was successful and .lib and .dll files are created.

However, linking this library with my application results in a link error.
The application is a 32-bit application using MFC.

The build of the "3626" branch created in the same procedure in January does not cause a link error, and the application works properly.

I think these two points.
New version of Visual Studio
New CEF branch

How do I create a library that can be linked successfully?

The libcef_dll_wrapper needs to be built with the same runtime settings as your application. Create a binary distribution from your build, and see https://bitbucket.org/chromiumembedded/ ... braries.md

I built my application using the /MT flag.
I built CEF with default settings, so the /MT flag should be used.
(I confirmed the contents of libcef_dll_wrapper.ninja.)
I think that both my application and my build CEF is same flag.
Are there any other possible causes?

Do cefclient and cefsimple applications build fine?

Yes, cefclient and cefsimple work fine.

Make sure you've copied correct .lib files including libcef.lib for the appropriate configuration (Release, Debug).

Also header files in the include/ directory.

Is libcef.lib about libcef.dll.lib?
I copied libcef.dll.lib and libcef_dll_wrapper.lib to the library directory.
For my application and the 3626 branch I could build with these two .lib files.
I don't use Sandbox.
Do I still need more?

I copied header files from \code\chromium_git\chromium\src\cef\include.

You can compare your compiler flags and linker flags with cefclient. Google the error message as well:

I compared with cefclient's compiler/linker flag (cefclient.ninja).
I changed the settings and tried to build, but the link error will not disappear.

I also compared it with the CEF binary distribution cefclient, but I did not get any useful information.

[naoki5]

I'm concerned about the error message "std::__1".
Is this related to libc++?
https://bitbucket.org/chromiumembedded/ ... ink-errors

I compared libcef_dll_wrapper.ninja with the 3626 branch.
I built successfully with the 3626 branch.
I built my application successfully with the 3626 branch.

The 3770 branch's .ninja had more configuration related to libc++, so I removed that configuration to make it the same as the 3626 branch.
When I build with this .ninja, I have libcef_dll_wrapper.lib which does not cause a link error.
However, when I build an application with this .lib file, it becomes an .exe file that can not be launched.
Of course, .lib files that I built without removing the configuration will cause link errors.
