# Dependencies
## General dependencies
```shell script
sudo apt-get install -y texinfo bison flex libglib2.0-dev
apt-get install gtk-doc-tools # For libnice later
```

## Python 3.6
```shell script
wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tgz && \
tar -xvf Python-3.6.3.tgz && \
cd Python-3.6.3 && \
sudo ./configure --enable-optimizations && \
make -j`nproc --all` && \
sudo make install && \
sudo update-alternatives --install /usr/bin/python python /usr/local/bin/python3.6 60 && \
sudo update-alternatives --install /usr/bin/python python /usr/bin/python2.7 50

# You may need to set the default python to 2.7 for this step (if "lsb_release -a" fails):
# sudo update-alternatives --config python
pip3.6 install --upgrade pip
```

## Ninja (from source)
```shell script
apt-get purge ninja

git clone git://github.com/ninja-build/ninja.git && \
cd ninja && \
git checkout release && \
./configure.py --bootstrap && \
mv ninja /usr/local/bin/
```

## Meson
```shell script
pip3.6 install meson
```

## objcopy
`objcopy` must be build from source because the option "--add-symbol" is mouse likely not available...  
You might have to append `--target=i386-pc-linux-gnu` for 32 bit PCs  
```shell script
git clone git://sourceware.org/git/binutils-gdb.git && cd binutils-gdb && \
CXXFLAGS="-Wno-error=unused-function -O2" CFLAGS="-Wno-error=unused-function -O2" ./configure && \
make -j`nproc --all` && \
make install && \
cd ..
```

# Troubleshooting
## GLIB2.0 hangs on meson
Ninja may be too old. It should work with 1.9.0.
