build error on debian #40

go-python3works fine for me on Debian 10. In my setup the env varPKG_CONFIG_PATHpoints to a dir with a file exactly namedpython3.pc(I needed to create a symlink with that name).Here's a Debian 10 Dockerfile example that works for me (even if you don't use Docker you should find the relevant parts in there):
FROM docker.io/library/debian:10 RUN apt-get -y update RUN apt-get -y install golang python3.7 python3.7-dev pkg-config libpython3.7 libpython3.7-dev git RUN ln -s /usr/lib/x86_64-linux-gnu/pkgconfig/python-3.7.pc /usr/lib/x86_64-linux-gnu/pkgconfig/python3.pc ENV PKG_CONFIG_PATH=/usr/lib/x86_64-linux-gnu/pkgconfig COPY hello /hello RUN cd /hello && go get . && go build -o /usr/local/bin/hello . CMD hello(
hellois a go program that prints a python string, all files are here).quickstart:
$ git clone https://github.com/christian-korneck/Dockerfiles $ cd Dockerfiles/debian-go-python3-demo/ $ docker build -t hello-demo . $ docker run --rm hello-demo hello from python in goHope this helps.
Hi, @christian-korneck , thank you very much for your patient.
I use debian 9 dokcer base image, python3.4 already installed on it. I can not changed to debian 10 for some reasons. And I noticed thatapt-get install python3.7andpython3.7-devnot works（Couldn't find any package by regex 'python3.7-dev'）, I've tried some ways to make it works such as addppa, all failed.
finally, I installed python3.7 by wget python3.7 source code and compile it. butgo-python3compile still failed(have set the PKG_CONFIG_PATH env). I think it is because python3.7-dev is not installed in my docker image, but I can not figure out how to install it even after google it for several days.I am very appreciate for your help
hi @YangChuanMakeSense ,
for building python did you use
configure --enable-shared? (this gives a working<prefix>/lib/pkgconfig/python3.pc) I just tried on Debian 9 and thisDockerfileworks for me:I've split this into three build steps. The first one builds python from src, the second one builds the go program against our custom python and the third one is for running the compiled Go program (a more minimal container with no build tools installed and both our go program and our custom python in
/opt). You could of course also all do it in one container or machine.# temp container to build python from source FROM docker.io/library/debian:9 as builder-python RUN apt-get -y update && apt-get -y install curl build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev RUN curl https://www.python.org/ftp/python/3.7.10/Python-3.7.10.tgz -o python.tgz && tar xf python.tgz RUN cd Python-3.7.10 && ./configure --enable-shared --prefix=/opt/py RUN cd Python-3.7.10 && make -j `nproc` RUN cd Python-3.7.10 && make install # temp container to build the go program FROM docker.io/library/debian:9 as builder-golang COPY --from=builder-python /opt/py /opt/py RUN echo /opt/py/lib > /etc/ld.so.conf.d/py.conf && ldconfig RUN apt-get -y update && apt-get -y install git curl pkg-config gcc RUN curl -L https://golang.org/dl/go1.16.2.linux-amd64.tar.gz -o go.tar.gz && tar -C /usr/local -xzf go.tar.gz ENV PKG_CONFIG_PATH=/opt/py/lib/pkgconfig COPY hello /hello RUN cd /hello && /usr/local/go/bin/go get . && /usr/local/go/bin/go build -o /opt/hello/bin/hello . # container to distribute the go program FROM docker.io/library/debian:9-slim COPY --from=builder-golang /opt/py /opt/py COPY --from=builder-golang /opt/hello /opt/hello RUN echo /opt/py/lib > /etc/ld.so.conf.d/py.conf && ldconfig CMD /opt/hello/bin/helloTo try:

--enable-sharedhelps a lot.Reacted by Christian Korneckhi @christian-korneck ，i had the same problem ,and i used pyenv to install the python3.7 with options configure --enable-shared.but it still doesnt work. i can't use docker. thanks for your help~
os：ubuntu 20.04@floki2020 this works for me on Ubuntu 20.04:
apt-get -y update && apt-get -y install curl build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev git curl pkg-config gcc # build/install Python 3.7 to /opt/py (note: this needs to be exactly Py 3.7) curl https://www.python.org/ftp/python/3.7.10/Python-3.7.10.tgz -o python.tgz && tar xf python.tgz cd Python-3.7.10 ./configure --enable-shared --prefix=/opt/py make -j `nproc` make install echo /opt/py/lib > /etc/ld.so.conf.d/py.conf && ldconfig # build/install latest stable Go curl -L https://golang.org/dl/go1.16.6.linux-amd64.tar.gz -o go.tar.gz && tar -C /usr/local -xzf go.tar.gz export PKG_CONFIG_PATH=/opt/py/lib/pkgconfig # fetch demo project cd $HOME git clone https://github.com/christian-korneck/Dockerfiles.git cd Dockerfiles/debian-go-python3-demo/hello # build demo project /usr/local/go/bin/go get . && /usr/local/go/bin/go build -o /opt/hello/bin/hello . # run demo project /opt/hello/bin/helloand you should see output
hello from python in go(sorry if it's a bit clunky, copied from an ssh client on my phone. But hopefully it should get you an idea how to get it to work?)
Describe what happened:
I got the following error when I compile the code
I've installed python3.7.6 and
pkg-config --cflags -- python3works fineDescribe what you expected:
No error
