[codeXiaoMing]

When running "gvsbuild build --enable-gi --py-wheel gobject-introspection gtk4 libadwaita gtksourceview5 pygobject pycairo adwaita-icon-theme hicolor-icon-theme" the following error occurs:

Hi @codeXiaoMing, this looks like the same issue as in #877. Is your language set to Chinese as well?

[codeXiaoMing]

Yes, my language is set to Chinese

[danyeaw]

Would it be possible to set your language to English to help isolate this to some type of unicode error?

[codeXiaoMing]

I have tried using VMware to create an English version of Windows and successfully configured the development environment. But I don't think this is a good choice, I will try this method https://www.cnblogs.com/Steven-HU/p/14547749.html

[danyeaw]

Was that method to change the system locale?

[codeXiaoMing]

yes, It also mentions that there are several other ways to solve this problem:

1. Modify the project file or source file, and disable the C4819 warning
2. Modify the file content to avoid using illegal characters
3. Save the file in Unicode format again

[danyeaw]

Hey @codeXiaoMing, I don't think this is specific to Gvsbuild, GLib (which was the code that PyGObject was building against when the error occurred) has some guidance which is to set the non-unicode language to English:
https://gitlab.gnome.org/GNOME/glib/-/blob/main/docs/win32-build.md#c4819-build-errors

It does give a 2nd option to use the /UTF-8 flag with MSVC, but it doesn't sound like that is always effective.

[codeXiaoMing]

@danyeaw you are right. The method you mentioned is what I mentioned earlier. I have successfully installed pygobject using this method

[codeXiaoMing]

I have already configured the environment according to the official installation process and successfully ran gaphors using “poetry run gaphor”, but an error occurred during the second run

It looks like it can't find PyGObject to import any longer. Do you still have your environmental variables set?

$env:Path = "C:\gtk-build\gtk\x64\release\bin;" + $env:Path
$env:LIB = "C:\gtk-build\gtk\x64\release\lib;" + $env:LIB
$env:INCLUDE = "C:\gtk-build\gtk\x64\release\include;C:\gtk-build\gtk\x64\release\include\cairo;C:\gtk-build\gtk\x64\release\include\glib-2.0;C:\gtk-build\gtk\x64\release\include\gobject-introspection-1.0;C:\gtk-build\gtk\x64\release\lib\glib-2.0\include;" + $env:INCLUDE

For the C4819 errors, do you think we should add that to the Gvsbuild README? Are you interested in making a pull request?

[codeXiaoMing]

After resetting these environment variables, there was no problem. thank you. I think it is necessary to add the C4819 errors to Gvsbuild README. My recent plan is to develop some customized content based on gaphor, and then I can organize the process for solving the C4819 error and make a pull request

I encountered an error while attempting to package when running this command：poetry run poe win-installer

@codeXiaoMing Ok, I'll leave this open until we update the docs.

Let's move Gaphor support to that project 👍
