Docker container does not compile

[timronan]

docker build . does not generate a docker image. The DockerFile Command RUN cd /build && CFLAGS="-O2" make fails with the error output below:

It seems like the makefile is failing during the cleanup process because the relative ../pcre/.libs/libpcre.a cannot be found within the partially compiled docker image (https://github.com/EarthScope/ringserver/blob/main/src/Makefile#L16). Potentially, the pcre dependency is not being made.

The makefile works when compiling a Ringserver within a virtual machine, and this issue is specific to compiling Docker Images using the DockerFile included in this repository.

I took the approach of switching the base to debian:bookworm-slim and starting debugging from there since centos:7 is EOL.

The line

8.828 cc: error: ../pcre/.libs/libpcre.a: No such file or directory

is a bit of a red herring as this project includes its own copy of the pcre library, so installing the Debian libpcre3-dev doesn't help. The issue seems to be higher up in the output with not being able to compile the local pcre library:

4.390 Running make all in pcre

Installing the automake package in addition to build-essential resolves this. MR coming including change to Debian as the base.

This branch works as expected:

docker build .
docker run -dit -p 18000 IMAGE_ID
docker ps
slinktool -Q -v IP:Port (Found using docker ps in PORTS column)

Returns:

Even this shouldn't be needed. The fundamental problem is one of time stamps of files getting modified and triggering autoconf to think it needs to be re-run, which it does not. It doesn't hurt to run automake again, but it could be avoided entirely. I'll see if I can something to #47 to address this.
