./sage -i pyopenssl fails to compile

I've tried multiple times to get this to work. I've tried with a clean install of the latest version of sage and the latest version of ubuntu. I've run make install build essentials, make install m4. I've spent hours on google with no answers. This is the result ./sage -i pyopenssl (relevant output)

Using cached cffi-1.6.0.tar.gz Complete output from command python egg_info: /usr/SageMath/local/bin/pkg-config: line 16: /home/buildbot/slave/binary_pkg/build/tools/binary-pkg/bin/pkg-config: No such file or directory /usr/SageMath/local/bin/pkg-config: line 16: /home/buildbot/slave/binary_pkg/build/tools/binary-pkg/bin/pkg-config: No such file or directory /usr/SageMath/local/bin/pkg-config: line 16: /home/buildbot/slave/binary_pkg/build/tools/binary-pkg/bin/pkg-config: No such file or directory /usr/SageMath/local/bin/pkg-config: line 16: /home/buildbot/slave/binary_pkg/build/tools/binary-pkg/bin/pkg-config: No such file or directory /usr/SageMath/local/bin/pkg-config: line 16: /home/buildbot/slave/binary_pkg/build/tools/binary-pkg/bin/pkg-config: No such file or directory gcc: error: /usr/SageMath/local/lib/gcc/: Is a directory gcc: error: /usr/SageMath/local/lib/gcc/: Is a directory

Error building Sage.

The following package(s) may have failed to build (not necessarily during this run of 'make pyopenssl'):

  • package: openssl-1.0.2g log file: /usr/SageMath/logs/pkgs/openssl-1.0.2g.log build directory: /usr/SageMath/local/var/tmp/sage/build/openssl-1.0.2g

The build directory may contain configuration files and other potentially helpful information. WARNING: if you now run 'make' again, the build directory will, by default, be deleted. Set the environment variable SAGE_KEEP_BUILT_SPKGS to 'yes' to prevent this.

Makefile:16: recipe for target 'pyopenssl' failed make: * [pyopenssl] Error 1

Does anyone have a clue how to fix this? I've run out of ideas, and have basically given up on making a secure sage server.

I think you may want to build Sage from scratch in this instance: note


suggests you are using a binary, which may not be able to deal with all compiling issues.

I tried to build from source, now I get a new error: line 14, in <module> from . import multiarray ImportError: cannot open shared object file: No such file or directory

Please email sage-devel ( ( explaining the problem and including the relevant part of the log file /usr/SageMath/logs/pkgs/sage-7.1.log Describe your computer, operating system, etc.

Huh, maybe you don't even have ATLAS on your computer, though it should compile then... I think this is not a discussion that will work well on this medium (it's a Q&A forum), can you try

I have the solution.

wget ""

tar zxvf cryptography-1.4.tar.gz cd cryptography-1.4/ ../local/bin/python install cd .. ./sage -i pyopenssl
