I created a bb file and tried to create an image. But it shows error

following is the bitbake file that I created

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

SRC_URI[md5sum] = "5fb5fb7ccb113ab3a039702b6c2f3327"
SRC_URI[sha256sum] = "8ab6e9c808bf2fb3e8576cd8cf07226d9cdc18b012c06d9708429a821ac6634e"

LICENSE = "BSD"
LIC_FILES_CHKSUM = "file://PKG-INFO;beginline=8;endline=8;md5=e910b35b0ef4e1f665b9a75d6afb7709"

PYPI_PACKAGE = "scipy"

S = "${WORKDIR}/scipy-${PV}"

RDEPENDS_${PN} += "python-numpy"

Hi mathew,

in your Yocto build directory you can launch command 'bitbake -s' and it will show all the available packages. You may 'grep' the output and look for python-scipy, if no output is found then it means the package is not available, but if you find it then you can add the package with that specific name.

You may add the module to your image by adding the following line to your local.conf file:

IMAGE_INSTALL_append += "package_name"

Regards,
Carlos

Hi Carlos,

Thanks you for your comments.

I tried as you mentioned in the above reply and I'm able to find python-scipy in the added packages. But on the target when I'm importing scipy it shows error(like python-scipy not found). Then I check for scipy package in the python2.7 directory it doesn't list anything. Hope you can help me.

Regards,

Mathew

Hi Mathew,

I was mistaken in the Syntax please try

IMAGE_INSTALL_append = " package_name"

Please note the leading space in the value to be appended.

If the problem persists please let e know.
