I’m having problems trying to build an image with erlang 26 compiled from source, when I run docker build . I get

 => ERROR [ 7/14] RUN /home/erl/otp_src_26.0.2/make                                                                                                                       0.3s

ERROR: failed to solve: process "/bin/sh -c /home/erl/otp_src_${ERLANG_VERSION}/make" did not complete successfully: exit code: 126

I’ve tried setting root user with USER root, using make 4.2 and chmod 777 the entire folder but nothing changes. I can follow the same steps on my local machine and they work.

Before this i was using https://packages.erlang-solutions.com/erlang-solutions_2.0_all.deb but they doesn’t provide the last versions.

I know i can use the official image, but I like to do it this way first

Here is the Dockerfile

FROM ubuntu:22.04

RUN wget -P /home/erl https://github.com/erlang/otp/releases/download/OTP-${ERLANG_VERSION}/otp_src_${ERLANG_VERSION}.tar.gz && \
    tar -xf /home/erl/otp_src_${ERLANG_VERSION}.tar.gz -C /home/erl

RUN /home/erl/otp_src_${ERLANG_VERSION}/configure

RUN /home/erl/otp_src_${ERLANG_VERSION}/make install && \
    rm -r /home/erl

WORKDIR /app

>Solution :

/home/erl/otp_src_${ERLANG_VERSION}/make is a directory and so you get the cryptic message ‘Permission denied’ when you try to run it.

The make executable isn’t located in the Erlang directory. It’s installed in /usr/bin. Make assumes that you’re running it from the directory where your project is located.

Instead of

RUN /home/erl/otp_src_${ERLANG_VERSION}/configure

RUN /home/erl/otp_src_${ERLANG_VERSION}/make 

RUN /home/erl/otp_src_${ERLANG_VERSION}/make install && \
    rm -r /home/erl

you can cd into the directory and run the commands you need. Like this

RUN cd /home/erl/otp_src_${ERLANG_VERSION} && \ 
    ./configure && \
    make && \
    make install && \
    cd / && \
    rm -r /home/erl
