使用WebAssembly配置QT问题：在Qt6ProtobufTools上失败，找不到WrapProtoc

Question

这就是我所做和尝试的， 我安装了QT 6.5.2，我还下载了emsdk 我通过

安装并激活emsdk

./emsdk install 3.1.25
./emsdk activate 3.1.25

然后我进入了位于 C:\Qt .5.2\Src 的 QT 源文件夹 并运行配置

./configure.bat -qt-host-path C:\Qt\6.5.2\mingw_64 -no-warnings-are-errors -feature-opengles3  -device-option QT_EMSCRIPTEN_ASYNCIFY=1 -platform wasm-emscripten -prefix $PWD/qtbase

我收到以下错误

-- Configuring submodule 'qtwebengine'
[QtWebEngine] -- Support check for QtWebEngine failed: Build can be done only on Linux, Windows or macOS.

我已经检查了我的 QT 安装并确认 QT 所需的一切都已安装

谷歌搜索错误没有产生好的结果。 我在这里缺少什么并且需要做什么？

Answer 1

apt install protobuf-compiler

为我解决了类似的问题。

Answer 2

作为解决方法，请尝试将“-skip qtgrpc”添加到 ./configure.bat 或使用 Qt 维护工具删除 Qt Protobuf 库。
