Protobuf 版本与 Qt 冲突 [英] Protobuf version conflicts with Qt
问题描述
我正在尝试将 protobufs v 3.3.2 与 Qt 5.9.1 一起使用.这适用于某些 Qt 应用程序，但前提是它们是命令行程序.一旦我用 Qt 和 protobufs 创建了一个 GUI 应用程序，我就会收到这个错误:
I'm trying to use protobufs v 3.3.2 with Qt 5.9.1. This works with some Qt applications, but only if they are command line programs. Once I create a GUI application with Qt and protobufs, I get this error:
[libprotobuf 致命/home/mkraus/Documents/dev/star385/build/linux-desktop-debug-libs/protobuf/src/src/google/protobuf/stubs/common.cc:78]此程序是针对 Protocol Buffer 运行时库的 2.6.1 版本编译的，该版本与已安装的版本不兼容版本 (3.3.2). 联系程序作者以获取更新.如果你自己编译程序，确保你的头文件来自与您的链接时库相同版本的协议缓冲区.(版本验证失败/build/mir-ui6vjS/mir-0.26.3+16.04.20170605/obj-x86_64-linux-gnu/src/protobuf/mir_protobuf.pb.cc".)

Contact the program author for an update. If you compiled the program yourself, make sure that your headers are from the same version of Protocol Buffers as your link-time library. (Version verification failed in "/build/mir-ui6vjS/mir-0.26.3+16.04.20170605/obj-x86_64-linux-gnu/src/protobuf/mir_protobuf.pb.cc".)
我应该澄清一下，我的代码部分肯定使用了 3.3.2 版本(我正在从 git 源下载和编译 protobufs 并进行静态链接).查看下面的堆栈跟踪，了解 Qt 引用的某些内容导致 protobuf 版本不匹配.
I should clarify that my part of the code is certainly using version 3.3.2 (I'm downloading and compiling protobufs from the git sources and statically linking). Look at the stack trace below to see that something that Qt is referencing is causing a protobuf version mismatch.
我在 Ubuntu 16.04 上开发并使用默认桌面环境 (Unity).
I'm developing on Ubuntu 16.04 and using the default desktop environment (Unity).
我的故障排除揭示了这些症状和解决方法:
My troubleshooting has revealed these symptoms and work-arounds:
使用 KDE/KUbuntu.登录时更改桌面环境完全避免了版本不匹配问题.
使用 -platform eglfs 运行 Qt 应用程序.这将使用 OpenGL 以全屏模式运行应用程序.程序运行，但窗口大小不正确.当使用 -platform eglfs 选项时，它甚至在 Unity 中也能工作，但是如果没有这个选项，它会给我上面的错误.
Run the Qt application with -platform eglfs. This runs the application in full-screen mode using OpenGL. The program runs, but the window size is incorrect. When using the -platform eglfs option, it works even in Unity, but without this option, it gives me the above error.
任何仅限命令行的 Qt 应用程序(使用 QCoreApplication 而不是 QGuiApplication)都可以使用 protobufs 3.3.2.将同一应用更改为使用 GUI 会导致版本不匹配问题.
Any Qt application that is a command-line only application (using QCoreApplication instead of QGuiApplication) can use protobufs 3.3.2. Changing the same app to use a GUI causes the version mismatch issue.
如何将 protobufs 3.3.2 与 Qt GUI 应用程序一起使用，并且不依赖于正在使用的桌面环境?是Qt用的protobufs 2.6.1版本吗，如果是的话，编译Qt用protobufs 3.3.2是否可行?
How can I use protobufs 3.3.2 with Qt GUI applications, and also not be dependent on what desktop environment is in use? Is it Qt that is using the version 2.6.1 of protobufs, and if so, is it feasible to compile Qt to use protobufs 3.3.2?
这是一个堆栈跟踪(程序在启动时几乎立即崩溃):
Here is a stack trace (the program crashes almost immediately upon starting):

推荐答案
你可以找到 在这里讨论同一问题，他们讨论了一个有趣的解决方法.
You can find here a discussion about the same issue and they talk about an interesting workaround.
这个错误似乎是由位于/opt/Qt/5.9/gcc_64/plugins/platformthemes 的库libqgtk3.so 引起的.如果您的项目中不需要它，您可以重命名/删除它以使错误消失.
It seems that this error is caused by the library libqgtk3.so located in /opt/Qt/5.9/gcc_64/plugins/platformthemes. If you don't need it in your project you can rename/remove it to make the error go away.
如果您使用 CMake 作为构建系统，您还需要注释文件 /opt/Qt/5.9/gcc_64/lib/cmake/Qt5Gui/Qt5Gui_QGtk3ThemePlugin.cmake 中的所有行以避免配置问题.
If you are using CMake as a build system you also need to comment all the lines in the file /opt/Qt/5.9/gcc_64/lib/cmake/Qt5Gui/Qt5Gui_QGtk3ThemePlugin.cmake to avoid configure issues.
另外，真正的问题来自依赖于 libprotobuf 的库 libmir.每当您尝试将最新的 tensorflow 与 libgtk3.0 一起使用时，您都可能会遇到此问题，因为这种硬依赖性.由于 libmir 依赖于系统 libprotobuf，它通常落后于 tensorflow 使用的版本(从存储库下载自己的版本).
To add on, the real problem comes from the library libmir which depends on the the libprotobuf. You may run on this problem whenever you try to use recent tensorflow with libgtk3.0 because of this hard dependency. As libmir depends on the system libprotobuf which is normally behind the version in use by tensorflow (which downloads its own version from the repository).
好消息是，libgtk 上的这个 BUG 已被报告并修复，但是要使用修复版本，您必须移动到 libgtk3.0 3.22(参见 BUG 报告).
The good news, this BUG on libgtk was reported and fixed however, to use the fixed version you have to move to libgtk3.0 3.22 (see BUG report).
