Docker build: /make: Permission denied

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

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
