[unbit]

you need uwsgi 2.1 to build it (vassal_attr_get is a 2.1 api function)

[anentropic]

I got uwsgi via:

RUN curl http://uwsgi.it/install | bash -s psgi /usr/bin/uwsgi

that's not 2.1? how do I get 2.1?

[unbit]

nope, that procedure always give the latest stable. Take the master from github, it is already used in production by lot of companies

[anentropic]

I don't even know where I found that install command now, I thought it was on the readme of this plugin :)

ok I have installed the master version in my docker image via:

RUN apt-get install -y libperl-dev
RUN curl -o /tmp/uwsgi_head.tar.gz -L https://github.com/unbit/uwsgi/tarball/master/
RUN mkdir uwsgi_head
RUN tar zvxC uwsgi_head --strip-components=1 -f /tmp/uwsgi_head.tar.gz
WORKDIR uwsgi_head
RUN UWSGI_PROFILE="default" UWSGI_BIN_NAME="/usr/bin/uwsgi" make

now I get this error:

[unbit]

a stupid typo :) if you rerun the procedure it should work

[anentropic]

it did! thanks for your help!
