I'm trying to compile something from github: https://github.com/com2m/anki-overdrive-goes-iot/
When Running Qmake everthings seems fine, but whe in run make i get the follwoing error:
g++ -c -pipe -g -std=gnu++11 -Wall -W -D_REENTRANT -fPIC -DQT_BLUETOOTH_LIB -DQT_CORE_LIB -I. -isystem /usr/include -isystem /usr/include/x86_64-linux-gnu/qt5 -isystem /usr/include/x86_64-linux-gnu/qt5/QtBluetooth -isystem /usr/include/x86_64-linux-gnu/qt5/QtCore -I. -I/usr/lib/x86_64-linux-gnu/qt5/mkspecs/linux-g++ -o main.o src/main.cpp

My research showed that there must be something wrong with the inculude path, but the path i assigned is my c++ includepath.
The stdlib.h can be found under:
/usr/include/c++/7/stdlib.h
Im'm running Kubuntu 18.04 and the library build-essentials is already installed.
/usr/include/c++/7/cstdlib:75:15: fatal error: stdlib.h: No such file or directory
sudo apt install g++ g++-5 libmosquittopp-dev libbluetooth-dev qtconnectivity5-dev
git clone https://github.com/com2m/anki-overdrive-goes-iot.git
cd anki-overdrive-goes-iot/
export QT_SELECT=5
qmake // the Makefile is generated
// Edit Makefile line 13 to CC = gcc-5
// and line 14 to CXX = g++-5
make
No errors.
Your errors: I guess it's kind of a bug somewhere, since the g++-7 header /usr/include/c++/7/stdlib.h is not found ? (Same issue with g++-6.)
