sudo apt install git libqt5gui5 bison flex qt5-default libboost-random-dev
or if you are not on a LTS version of Ubuntu:
sudo apt install git libqt5gui5 bison flex qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools libboost-random-dev
git clone https://github.com/cs233/qtspimbot.git
Make the program with qmake && make -j<number of threads on your machine> while in /QtSpim
You can debug the program with qmake DEBUG=1 && make -j<number of threads on your machine> which will add debug symmbols that can be read by gdb.
sudo apt install git bison flex # linux
brew install bison flex # mac
brew unlink bison
echo 'export PATH="/usr/local/opt/bison/bin:$PATH"' >> ~/.zshrc
export LDFLAGS="-L/usr/local/opt/bison/lib"
source ~/.zshrc # mac on zsh shell (default)
brew unlink bison
echo 'export PATH="/usr/local/opt/bison/bin:$PATH"' >> ~/.bash_profile
export LDFLAGS="-L/usr/local/opt/bison/lib"
source ~/.bash_profile # mac on bash shell
git clone https://github.com/cs233/qtspimbot.git
git clone https://github.com/emscripten-core/emsdk.git
# mac-only
./emsdk install binaryen-main-64bit
./emsdk activate binaryen-main-64bit
# mac+linux
./emsdk install 1.39.8
./emsdk activate 1.39.8
source ./emsdk_env.sh
You will need to run source ./emsdk_env.sh everytime you load a new terminal, so it's good to add it to your .bashrc or .bash_profile.
Boost normally installs within the g++ libraries. However, since we are using em++, it uses its own libraries.
So, we need to paste in the boost headers into emscripten.
wget https://github.com/emscripten-ports/boost/releases/download/boost-1.75.0/boost-headers-1.75.0.zip
unzip boost-headers-1.75.0.zip -d <path to emsdk>/upstream/emscripten/system/include
We are going to be using Qt 5.15.2 since its corresponding known-good version of Enscripten is 1.39.8
wget https://download.qt.io/archive/qt/5.15/5.15.2/single/qt-everywhere-src-5.15.2.tar.xz
tar -xf qt-everywhere-src-5.15.2.tar.xz
mv qt-everywhere-src-5.15.2 qt-5.15.2
cd qt-5.15.2
mkdir build && cd $_
../configure -static -release -no-pch -xplatform wasm-emscripten -skip qtwebengine -nomake tools -nomake tests -nomake examples
If you are having trouble, try adding -no-feature-thread to the last command to enable single threaded configuration wasm.
On linux, the last thing that is output suggests you to install libclang-dev which can be done with:
sudo apt install libclang-dev
Now, Build Qt5:
time make -j6
the following should work as well
time make -j<as many threads as possible bc this will take a LONG time> install
For my i5-8500 (6 threads), it took a whopping 44 mins 39.9 secs!
qmake will then be installed in build/qtbase/bin
sudo ln -s $PWD/qtbase/bin/qmake /usr/bin/qmake-wasm <--- causing errs bruhhhhh
# try this one
(printf 'alias qmake-wasm=\"%s/qtbase/bin/qmake\"\n' $PWD) >> ~/.bash_profile; source ~/.bash_profile
Now, when you do qmake-wasm --version, the output should be:
QMake version 3.1
