Updating gcc for Azure function in R with Docker

Question

Hello,

I am trying to deploy an Azure function in R with Docker. Certain packages require gcc >= 9 (C++17) but
I am unable to update it.

Dockerfile:

FROM mcr.microsoft.com/azure-functions/dotnet:3.0-appservice   
ENV AzureWebJobsScriptRoot=/home/site/wwwroot \  
    AzureFunctionsJobHost__Logging__Console__IsEnabled=true  
  
RUN apt-get install -y r-base r-base-dev  
RUN apt-get update -qq && apt-get install -y \   
   libssl-dev \   
   libcurl4-gnutls-dev \  
   libsodium-dev \  
   libxml2-dev  
  
RUN apt-get install -y gcc  
RUN gcc --version   
  
COPY  install_packages.R install_packages.R  
RUN Rscript /install_packages.R  
COPY . /home/site/wwwroot  

Do you have any suggestions on how to update gcc or install R with the correct version of gcc?

Hello @Mislav Sagovac

According to Microsoft Dockerhub repo you are using image mcr.microsoft.com/azure-functions/dotnet:3.0-appservice based on Debian 10 (Buster)
Unfortunately there is no gcc-9 or higher version of this package for Debian 10 (Buster)
https://packages.debian.org/search?keywords=gcc-9

I could suggest you to use newer Microsoft Dockerhub image mcr.microsoft.com/azure-functions/dotnet:4.0-appservice
or try to build it from sources https://gist.github.com/s3rvac/76ac07f21d5635209accc11fa56bd3fb
You will need to add few commands into your Dockerfile

ADD "https://gist.githubusercontent.com/s3rvac/76ac07f21d5635209accc11fa56bd3fb/raw/70c33cf0121348aa33a2159449ac64afcfac01b0/gcc-10-debian-buster.sh" /script/gcc-10-debian-buster.sh  
RUN chmod +x /script/gcc-10-debian-buster.sh  
RUN /script/gcc-10-debian-buster.sh
