Public bug reported: I am trying to compile on my Ubuntu Trusty 14.04 the latest source cffi-1.3.1 in order to build the python-cffi package.
The source and debian folder are available at: https://launchpad.net/ubuntu/+source/python-cffi Here are the steps I took: $ wget -P ~/Downloads/cffi https://launchpad.net/ubuntu/+archive/primary/+files/python-cffi_1.3.1.orig.tar.gz $ wget -P ~/Downloads/cffi https://launchpad.net/ubuntu/+archive/primary/+files/python-cffi_1.3.1-1ubuntu1.debian.tar.xz $ cd cffi $ tar zxf python-cffi_1.3.1.orig.tar.gz $ XZ_OPT=-9 tar Jcf python-cffi_1.3.1.orig.tar.xz cffi-1.3.1/ $ rm python-cffi_1.3.1.orig.tar.gz $ tar xf python-cffi_1.3.1-1ubuntu1.debian.tar.xz -C cffi-1.3.1/ $ cd cffi-1.3.1/ $ dpkg-checkbuilddeps $ dpkg-buildpackage -rfakeroot -us -uc -Zxz -z9 Then I stumble on this error: running build_ext failed to import Cython: /usr/lib/python2.7/dist-packages/Cython/Compiler/Scanning.so: undefined symbol: Py_InitModule4_64 error: Cython does not appear to be installed [81526 refs] E: pybuild pybuild:256: build: plugin distutils failed with: exit code=1: /usr/bin/python-dbg setup.py build dh_auto_build: pybuild --build -i python{version}-dbg -p 2.7 --dir . returned exit code 13 make: *** [build] Error 13 dpkg-buildpackage: error: debian/rules build gave error exit status 2 The symbol Py_InitModule4_64 is not defined in the shared library Scanning.so, as the following cmd. confirms: $ nm -gl /usr/lib/python2.7/dist-packages/Cython/Compiler/Scanning.so | grep Py_InitModule4_64 nm: /usr/lib/python2.7/dist-packages/Cython/Compiler/Scanning.so: no symbols $ However from the Python environment the import seems to succeed: $ python Python 2.7.6 (default, Jun 22 2015, 17:58:13) [GCC 4.8.2] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> from Cython.Compiler import Scanning >>> As I was unable to recompile the latest source, I tried to recompile the "official" Trusty 14.04 source python-cffi_0.8.2.orig.tar.gz And I stumbled on the very same error ... What is wrong here ? Why can't we recompile the package from source ?
