Set python dist-packages path for autotools in Yocto bitbake

Question

I am trying to write a bitbake file for a project with uses autotools to configure the Makefiles.

### tizonia.bb
SUMMARY = "Tizonia Library"
DESCRIPTION = "Tizonia"
LICENSE = "LGPL-3.0"
LIC_FILES_CHKSUM = "file://COPYING.LESSER;md5=e6a600fd5e1d9cbde2d983680233ad02"

SRC_URI = "git://github.com/tizonia/tizonia-openmax-il.git;protocol=https"
SRCREV = "9004bc40b89eeafb04b28fbb2b772e47dd62fdc9"

S = "${WORKDIR}/git"

DEPENDS = "python-dev python-setuptools mediainfo log4c python-pip python-soundcloud"

inherit autotools ccache pkgconfig python-dir pythonnative

RDEPENDS_${PN} = "libstdc++ dbus boost libgcc mediainfo log4c libspotify python-pip python-soundcloud"

### python-soundcloud.bb
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://LICENSE;md5=31fa3a9dc818e0087893d63583d2d21a"

SRC_URI[md5sum] = "40c1d32afd019ed11ec1fbee3e84e31f"
SRC_URI[sha256sum] = "aad2003592cec945f835f158f7b41ba8bf805c5738a2fcc5629668ea1df653d5"

DEPENDS = "${PYTHON_PN}-modules"

PYPI_PACKAGE = "soundcloud"

inherit pypi setuptools

RDEPENDS_${PN} = "${PYTHON_PN}-modules"

In the do_configure step where the configure script is called, I get this error message:

| checking for python2.7... (cached) /home/developer/build-webos-ose/BUILD/sysroots/x86_64-linux/usr/bin/python-native/python

| configure: error: failed to find required module soundcloud

As you can see, configure is using sysroots/x86_64-linux/usr/lib/python2.7/site-packages for finding modules, but the modules are installed in sysroots/raspberrypi3/usr/lib/python2.7/site-packages.

How can I set the site-packages path in autoconf/configure call so it points to the correct path?

Can you provide your recipe? do you have inherit distutils inside? – Dubbin

@Dubbin Added the recipes – Samuel

did you try to remove pythonnative from inherit list? – Dubbin

@Dubbin Yes, but then I am getting another error. Gonna post it in a bit – Samuel

@Dubbin | checking consistency of all components of python development environment... no | | Could not link test program to Python. Maybe the main Python library has been | installed in some non-standard library path. If so, pass it to configure, | via the LDFLAGS environment variable. | Example: ./configure LDFLAGS="-L/usr/non-standard-path/python/lib" | | ERROR! | You probably have to install the development version of the Python package | for your distribution. The exact name of this package varies among them. – Samuel

@Dubbin I think I have to configure an autoconf variable called AC_CHECK_TOOL. See this patch for an example. – Samuel

Answer 1

Keep in mind that the configure script is executed on the HOST and it looks for tools that are needed for compilation on the HOST as well, hence what you need is to DEPEND on the python-soundcloud-NATIVE package (you might need to use BBCLASSEXTEND for this package to exist), meaning that what that package installs, will be populated automatically on recipe-sysroot-native/x86_64-linux/usr/lib/python2.7/site-packages (since it DEPENDs on it) which is what the configure script will read automatically as well.

Are you sure that configure script should be executed natively and not in cross-compile target environment? – Dubbin

The cross compilers are also executed on the host, thats why they are cross compiling from host to target, plus you literally checked the path from which its trying to pull python libraries and the x86_64-linux part gives it away. – Parotic

@aehs29 Adding python-soundcloud-native to DEPENDS instead of python-soundcloud resulted in the same error. – Samuel
