• Same error with cffi, another python package.
• Both cffi and numpy are written in C.

See #85. Also this regarding building projects with lots of extensions:

https://github.com/1and1/debianized-sentry/blob/master/debian/rules

(take note of the overrides)

I still can't compile numpy.

Here are my debian rules.

\#!/usr/bin/make -f 

CFLAGS += -shared

export DH_VIRTUALENV_INSTALL_ROOT=/opt/venvs
SNAKE=/usr/bin/python2
EXTRA_REQUIREMENTS=--upgrade-pip --preinstall "setuptools>=17.1" --preinstall "wheel" --preinstall "numpy"


PACKAGE=$(shell dh_listpackages)
VERSION=$(shell parsechangelog | grep ^Version: | sed -re 's/[^0-9]+([^-]+).*/\1/')
DH_VENV_ARGS=  --with python-virtualenv --setuptools --python $(SNAKE) $(EXTRA_REQUIREMENTS)  --extra-pip-arg='--no-binary' --extra-pip-arg=':all:' -v 


%:
	dh $@ $(DH_VENV_ARGS) 

override_dh_strip:
	dh_strip  --exclude=cffi --exclude=symsynd --exclude=selenium

override_dh_shlibdeps:
	dh_shlibdeps -X/x86/ 

The error I get is:

    collect2: error: ld returned 1 exit status
    error: Command "/usr/bin/gfortran -Wall -g -Wl,-Bsymbolic-functions -Wl,-z,relro build/temp.linux-x86_64-2.7/numpy/linalg/lapack_litemodule.o build/temp.linux-x86_64-2.7/numpy/linalg/lapack_lite/python_xerbla.o -L/usr/lib/atlas-base/atlas -L/usr/lib/atlas-base -Lbuild/temp.linux-x86_64-2.7 -llapack -lf77blas -lcblas -latlas -lf77blas -lcblas -lgfortran -o build/lib.linux-x86_64-2.7/numpy/linalg/lapack_lite.so" failed with exit status 1

Can you help me?

[jhermann]

The relevant file is control, and your build-deps are wrong. Well, most likely.

This issue may have been fixed in patchelf by NixOS/patchelf#117, but wheels will need to be re-built

[jhermann]

Take out the --nobinary option, then it builds at least on amd64 platforms.
See https://github.com/1and1/debianized-jupyterhub which packages all of the data science stack using binary wheels.

Also https://dh-virtualenv.readthedocs.io/en/latest/howtos.html#handling-binary-wheels

Can be closed.

[jhermann]

Bump. Can still be closed. I have projects that build OK with the scipy stack.

@nailor Close it already? ;)

[nailor]

Whops, missed it. Feel free to close yourself btw too, I don't think we disagree that often if ever 😊
