To automatically build a docker image:

1. create a folder named "harbour_docker"

2. inside that folder create a file named "Dockerfile"

Dockerfile

Code: Select all  Expand view

FROM debian
RUN apt-get update -y
RUN apt-get install mc -y
RUN apt-get install gcc -y
RUN apt-get install git -y
RUN git clone https://www.github.com/harbour/core harbour
RUN /bin/bash

3. docker build harbour_docker -t debian_harbour

4. docker run -it debian_harbour /bin/bash

X11: (Termux)

pkg install x11-repo
pkg install libx11-dev

libX11.a is missing and has to be built using this:
https://github.com/termux/x11-packages

to build it we use a docker linux with docker into it:
git clone https://github.com/termux/x11-packages
docker build x11-packages
cd ./x11-packages
./start-builder.sh
./build-package.sh -a ${arch} ${package name}
