[blekenbleu]

## My first Qt experience..
## How to implement 64-bit Qt 4 Serial Port support?

## Following instructions at
https://github.com/mcallegari/qlcplus/w ... uild-HOWTO
qmake -spec macx-g++
make
##-> failed for
./qtserial-interface.h:23:10: fatal error: 'QtSerialPort/QSerialPort' file not found

## Based on https://wiki.qt.io/Qt_Serial_Port
git clone git://code.qt.io/qt/qtserialport.git
cd qtserialport/
git checkout qt4-dev
cd ..
mkdir qtserialport-build
cd qtserialport-build/
qmake -spec macx-g++ ../qtserialport/qtserialport.pro
make
sudo make install

## Now fails at plugin link step

cd ../qlcplus-4.10.2
git diff qlc.pro

What is this ??
And moreover, why would you want to use Qt 4 on a recent OSX version ? That's most likely not supported.

You need to follow the Qt 5 build howto: https://github.com/mcallegari/qlcplus/w ... -build-Qt5

Sorry, I mistakenly thought qlcplus 4.10.2b still used Qt 4.
