Bug#992669: python3.9-dev: python3.9-config --cflags includes -specs=/usr/share/dpkg/no-pie-compile.specs
Matthias, I've added the --embed flag to the python3.9-config options in my Dockerfile example above, but have the same result. Apparently the specs file comes from libdpkg-perl. I don't understand what the specs file actually does, but I was able to build with or without it. If it *is* supposed to be in the flags for something, libdpkg-perl should at least be a "suggests" if not "recommends", right?

You have to call python3-config with the --embed options for the embedded case. That will get you the complete options needed for embedding an interpreter. I'm not sure I want to have these extra dependencies as part of the python3.9-dev package. You also don't write which options are missing from your build.

Package: python3.9-dev Version: 3.9.2-1 Severity: normal X-Debbugs-Cc: watts.mark2...@gmail.com Dear Maintainer, I'm using the python3.9-config --cflags to provide flags for building a program that embeds python. I'm doing this in a Docker container with the essential parts described by the Dockerfile excerpt below. I would expect that any files referenced in the CFLAGS would be installed along with python3.9-config. Instead, I have to install another package to get this file or do a sed on cflags to remove the -specs argument. Dockerfile: ``` FROM debian:11 ENV PYTHON_VERSION 3.9 # pkg-config is needed because, somehow, the CFLAGS in the python config script # adds a flag that depends on a file from a package pkg-config depends on...
