static linking

[Milan Nikolic]

Hi,

I am trying to build statically linked binary for my app. I have a static build of Qt 5.5.1 and mesa 11.0.5 in my /opt and all needed static builds of libraries are in /usr. 

First I was getting warnings about missing plugins when I run the app, so now I have this in cpp/plugins.cpp which is included from all.cpp:

#include <QtCore/QtPlugin>

Q_IMPORT_PLUGIN(QXcbIntegrationPlugin)

Q_IMPORT_PLUGIN(QXcbGlxIntegrationPlugin)

Q_IMPORT_PLUGIN(QXcbEglIntegrationPlugin)

Q_IMPORT_PLUGIN(QtQuick2Plugin)

Q_IMPORT_PLUGIN(QtQuickControlsPlugin)

Q_IMPORT_PLUGIN(QtQuick2DialogsPlugin)

Q_IMPORT_PLUGIN(QtQuickLayoutsPlugin)

Q_IMPORT_PLUGIN(QtQuick2WindowPlugin)

Q_IMPORT_PLUGIN(QmlSettingsPlugin)

Q_IMPORT_PLUGIN(QtQuick2PrivateWidgetsPlugin)

Q_IMPORT_PLUGIN(QJp2Plugin)

Q_IMPORT_PLUGIN(QEvdevKeyboardPlugin)

Q_IMPORT_PLUGIN(QEvdevMousePlugin)

Final build is linked to these plugins but now it crashes:

Shared build works just fine.  Qt is built with both EGL and GLX, mesa is built with swrast drivers and xlib-glx. 

This is how I build app, I also changed some Qt pkgconfig files in order to link succesfully:

PKG_CONFIG_PATH=/opt/qt/lib/pkgconfig:/opt/mesa/lib/pkgconfig:/usr/lib/pkgconfig \

PKG_CONFIG_LIBDIR=/opt/qt/lib/pkgconfig:/opt/mesa/lib/pkgconfig:/usr/lib/pkgconfig \

CGO_LDFLAGS="-L/opt/qt/lib -L/opt/qt/plugins/generic -L/opt/qt/plugins/platforms -L/opt/qt/plugins/imageformats -L/opt/qt/qml/QtQuick.2 -L/opt/qt/qml/QtQuick/Controls -L/opt/qt/qml/QtQuick/Dialogs -L/opt/qt/qml/QtQuick/Layouts -L/opt/qt/qml/QtQuick/Window.2 -L/opt/qt/qml/Qt/labs/settings -L/opt/qt/qml/QtQuick/PrivateWidgets -L/opt/qt/plugins/xcbglintegrations" \

CGO_ENABLED=1 GOOS=linux GOARCH=amd64 go build -v -x -o build/cbconvert-static --ldflags '-extldflags "-static"'

Does anyone have idea why it crashes or has done similar with go-qml?

I managed to compile static binary for Windows, with qt compiled with -opengl desktop. For Linux I have binary that has most of the libs compiled statically but libGL and some X libraries are shared. 

Project is here https://github.com/gen2brain/cbconvert . 

I had to add this file in cpp/ and include it in all.cpp - https://gist.github.com/gen2brain/c0982e4533b6d9ee9358 . Also, I needed this patch so I can compile in all qml files in .exe  - https://github.com/go-qml/qml/pull/163 .
