rpmbuild failed with syntax error

[gr790]

Hello,

I am trying to create an rpm from source code. I have pip 9.0.2 installed and Python version is 2.7.5.
I have written a .spec file for creating RPM out of this source code.
But it fails with syntax error.
``

• /usr/lib/rpm/redhat/brp-compress
• /usr/lib/rpm/redhat/brp-strip-static-archive /usr/bin/strip
• /usr/lib/rpm/brp-python-bytecompile /usr/bin/python 1

  yield from self.wsgi.close()
  ^
  SyntaxError: invalid syntax

``

Any Idea..?

I agree with the point that it is harmless, and pip install gunicorn=19.0 works fine, but why it failed to create package....

Thanks,
Rahul.

Because it tries to compile a Python 3-only file with Python 2. I don't know anything about rpmbuild, but I think there should be a way to extract some files from the build or a way to tell rpmbuild to build Gunicorn with /usr/bin/python3 or /usr/bin/python3.Y.

According to a gevent commentor you can put %define _python_bytecompile_errors_terminate_build 0 in your spec to stop this from being a problem.

Hello,

Thanks for your help, But I solved it by using 'exit 0' at the end of %install section in my rpm spec file, just to ignore any error during build..
Closing this issue.

Regards.

My solution

%global __python %{__python3}
