build fails on Debian 10 (buster / stable)

[dpocock]

gcc 8.3.0 in Debian 10 seems to have some issues with noexcept, can you provide a workaround for building in this environment?

Hi!

I can't reproduce this problem. There is my Dockerfile used for checking:

FROM debian:10

# Prepare build environment
RUN apt-get update && \
    apt-get -qq -y install gcc g++ ruby \
    wget libpcre2-dev libpcre3-dev pkg-config \
     libboost-all-dev \
     libssl-dev \
     git \
    libtool
RUN gem install Mxx_ru

ARG hgrev=HEAD

RUN echo "*** Downloading RESTinio ***" \
    && cd /tmp \
    && git clone https://github.com/stiffstream/restinio \
    && cd restinio \
    && git checkout $hgrev

RUN echo "*** Extracting RESTinio's Dependencies ***" \
    && cd /tmp/restinio \
    && mxxruexternals

RUN echo "*** Getting CMake ***" \
    && apt-get update \
    && apt-get -y install cmake

RUN echo "*** Building RESTinio ***" \
    && cd /tmp/restinio/dev \
    && mkdir cmake_build \
    && cd cmake_build \
    && cmake -DCMAKE_INSTALL_PREFIX=target -DCMAKE_BUILD_TYPE=Release .. \
    && cmake --build . --config Release \
    && cmake --build . --target test \
    && cmake --build . --target install

Could you modify it to make the error reproducible?
