wxwidgets/build/tools/autoconf

Docker container for running autoconf

Rationale

We store generated configure in Git to make it simpler for people to build wxWidgets without having to run autoconf themselves first, but this means that generating it on another system often results in insignificant changes just due to a different version of autoconf being used. By using this container, we can use the same version everywhere.

To use it, first build the container, then run it, see below.

Build

Just run

$ docker build -t autoconf-for-wx build/tools/autoconf

This should (quickly) finish with

Successfully tagged autoconf-for-wx:latest

Run

Use the following command to update configure from configure.ac:

$ docker run -v `pwd`:/wx --rm autoconf-for-wx

It should be run from the top-level wx directory.

Updating autoconf version

When we decide to switch to a newer autoconf version, we should update the Dockerfile here to use a later version of Alpine Linux: the currently used version is specifically chosen because it has the package with the latest version of autoconf 2.69.
