Hello,

I am trying to set up a automated build for Spot in a docker like environment. The build errored during the `make` step. I have been able to run it fine on my machine, so I hope it is just a dependency/version issue. Do you have any idea what dependency I could be missing?  

I did not installed anything besides python3-dev and got provided with an alpine linux distribution with gcc 7 already installed, this is the configuration I have:

Configuration:

OS: Alpine Linux

Gcc --version: gcc (GCC) 7.1.0

G++ --version : g++ (GCC) 7.1.0

Clang --version:  clang version 6.0.1

Spot source:

https://gitlab.lrde.epita.fr/spot/spot/-/jobs/21303/artifacts/download

(spot 2.6.3 dev)

The build script :

apk add python3-dev

cd $WORKSPACE/srcdir

unzip download

tar -xzf spot-2.6.3.dev.tar.gz

cd spot-2.6.3.dev

./configure --prefix=$prefix --host=${target}

make -j${nproc}

make install

Extract of the log :
