Build fails on Ubuntu Noble

We are attempting to upgrade the base distribution of our containers to Ubuntu Noble. Using the latest g++ build tools exactextract has trouble using the cstdint typedefs. The first error is as below. I have attempted to import cstdint in a few headers and build can progress. Perhaps failing early using a CMake g++ max version constraint will help.

This error can be reproduced by changing the FROM line in the included Dockerfile to FROM ubuntu:noble and firing off a build using docker build.

Resolution

A workaround is to install and activate gcc/g++-12 toolchain as the default instead.

FROM ubuntu:noble

LABEL maintainer="dbaston@isciences.com"

RUN apt-get update && apt-get install -y \
  build-essential \
  gcc-12 \
  g++-12 \
  cmake \
  curl \
  doxygen \
  gdal-bin \
  git \
  graphviz \
  libgdal-dev \
  libgeos-dev \
  python3-dev \
  python3-pybind11 \
  python3-pytest \
  unzip \
  wget

RUN update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-12 10
RUN update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-12 10
