steno

Steno GUI app

uses the golang Qt bindings at https://github.com/therecipe/qt.

Building

Rather than plain go build, use qtdeploy to make sure all the Qt moc generation magic happens. qtdeploy can build natively or in a docker container. Very handy for cross-compiling.

To do a native build:

$ qtdeploy build desktop

To cross compile a windows static build (after following the therecipe/qt instructions for installing an appropriate docker image):

$ qtdeploy -docker build windows_64_shared

(could also do windows_64_static, but had some stability issues...)

Troubleshooting

modules vs GOPATH

Bleve has now moved entirely to use golang modules. I don't think you can mix GOPATH and modules, so the Qt bindings need to be installed as a module too.

The Qt bindings wiki covers using them as modules (and vendoring the into the project). See the platform-specific directions at: https://github.com/therecipe/qt/wiki/Installation

Link errors after cross-platform builds

There is a Qt issue when doing cross-platform builds. For me, a windows docker build caused a subsequent native linux build to fail with link errors like this:

/usr/bin/ld: $WORK/b210/_x005.o: in function `StaticQWindowsVistaStylePluginPluginInstance::StaticQWindowsVistaStylePluginPluginInstance()':
../../vendor/github.com/therecipe/qt/core/core_plugin_import.cpp:5: undefined reference to `qt_static_plugin_QWindowsVistaStylePlugin()'
...

It appears to be https://github.com/therecipe/qt/issues/429

Removing the *_plugin_import* files seemed to do the trick:

$ find ../../vendor/github.com/therecipe/qt -type f -iname "*_plugin_import*" | xargs rm
