macOS: Qt from Qt Online Installer causes fatal error: 'QAbstractAnimation' file not found

[bitflying]

I am new to try to use miqt.

After installing Qt6.10.0, I ran

$ go run github.com/mappu/miqt/examples/helloworld6 

and got error repeatly

# github.com/mappu/miqt/qt6
gen_qabstractanimation.cpp:1:10: fatal error: 'QAbstractAnimation' file not found

Can not fixed it.

I have set enviroment in my .bash_profile as follow:

################################################
# Qt6 from official installer (UPDATE VERSION AND PATH)
export QT_DIR="$HOME/Qt6/6.10.0/macos"
export Qt6_DIR="$QT_DIR"
export PATH="$QT_DIR/bin:$PATH"
export LDFLAGS="-L$QT_DIR/lib"
export CPPFLAGS="-I$QT_DIR/include"
export PKG_CONFIG_PATH="$QT_DIR/lib/pkgconfig"

# CGO flags for miqt
export CGO_CXXFLAGS="-std=c++17 -I$QT_DIR/include"
export CGO_LDFLAGS="-F$QT_DIR/lib -L$QT_DIR/lib"

And tried Qt6.9.3, got same error.

tried:

$ pkg-config --cflags Qt6Core

-DQT_CORE_LIB -I/Users/qt/work/install/lib/QtCore.framework/Headers -I/Users/qt/work/install/lib/QtCore.framework -I/Users/qt/work/install/mkspecs/macx-clang -I/Users/qt/work/install/include

may be prefix error: should be "$HOME/Qt6/6.10.0/macos" instead of "/Users/qt/work/install"

I do not know how to fix it, any one can help ?

Thanks in advance!

My Mac:

1. an old intel mac-pro
2. run macOS Sonoma 14
3. go version go1.24.6 darwin/amd64
4.  Qt6 verson 6.10.0 installed via qt-online-installer

I think this is the same problem as #231 .

• One workaround is to copy the *.pc files to a new directory, edit them to fix the install paths, and set the PKG_CONFIG_PATH environment variable so that CGO finds your fixed *.pc files.
• Another workaround is to switch to another Qt distribution (e.g. Homebrew).

But really, a proper fix would be to raise a QTBUG upstream with Qt.

I've raised https://bugreports.qt.io/browse/QTBUG-141240 upstream for clarification.

thanks @mappu,

After asking Claude.ai many times and doing a few tries. I got a workable solution with some warnings.

add the follows into ~/.bash_profile

# Qt6 from official installer (UPDATE VERSION AND PATH)
export QT_DIR="$HOME/Qt6/6.9.3/macos"
export PATH="$QT_DIR/bin:$PATH"
export LDFLAGS="-L$QT_DIR/lib"
export CPPFLAGS="-I$QT_DIR/include"
export PKG_CONFIG_PATH="$QT_DIR/lib/pkgconfig:$PKG_CONFIG_PATH"

# CGO flags for miqt
export CGO_CXXFLAGS="-std=c++17 -F$QT_DIR/lib -I$QT_DIR/lib/QtCore.framework/Headers -I$QT_DIR/lib/QtGui.framework/Headers -I$QT_DIR/lib/QtWidgets.framework/Headers -I$QT_DIR/lib/QtQml.framework/Headers -I$QT_DIR/lib/QtQuick.framework/Headers -I$QT_DIR/include"

# CRITICAL: Add -Wl,-rpath to tell the executable where to find Qt frameworks at runtime
export CGO_LDFLAGS="-F$QT_DIR/lib -L$QT_DIR/lib -Wl,-rpath,$QT_DIR/lib"

But, these configuration maybe do something wrong to the other go projects!
