Building scipy with yocto 2.2

Hi,


Has anyone tried building python-scipy with yocto 2.2. Our bitbake file looks like this:

SUMMARY = "Scientific Library for Python"
SECTION = "devel/python"
HOMEPAGE = "https://pypi.python.org/pypi/scipy"

LICENSE = "BSD-3-Clause"
LIC_FILES_CHKSUM = "file://LICENSE.txt;md5=d0db8f4148a3d5534cfb93be78f9287c"

PYPI_PACKAGE="scipy"

SRC_URI[md5sum] = "53fa34bd3733a9a4216842b6000f7316"
SRC_URI[sha256sum] = "87ea1f11a0e9ec08c264dc64551d501fa307289460705f6fccd84cbfc7926d10"

inherit pypi setuptools distutils

RDEPENDS_${PN} += "python-core python-numpy-native python-distutils"
DEPENDS += "python-numpy-native"

RDEPENDS_${PN}_class-native += ""
BBCLASSEXTEND = "native nativesdk"

do_compile_prepend_class-target() {
    ${STAGING_BINDIR_NATIVE}/python-native/python setup.py build
}

Bitbake compiles the python-scipy half way and then it is not able locate lapack/blas resources.
My build machine is x86_64 and I am building it for arm architecture 64 bit.

Let me know if anyone has come across such situation.

Thanks and regards,
Harini

Hey Harini,

This email should be sent to the meta-openembedded or the oe-core list.

Also, scipy needs a math library (BLAS,LAPACK,ATLAS), and that needs to be cross compiled, you have to find  (it didn't exist back when I tried this) or create a recipe for it.
