Help with building app recipe

[Neuer User]

Hello

I am trying to build a simple recipe for a package called "pyotherside".
It currently looks like this:

------------------------------------------------------------------------
SUMMARY = "Python3 bindings for Qt5"
DESCRIPTION = "New framework for including pyhton interpreter into Qt5 apps"
HOMEPAGE = "http://thp.io/2011/pyotherside/"
LICENSE = "MIT"
LIC_FILES_CHKSUM =
"file://${COMMON_LICENSE_DIR\}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"

PV = "1.2+git${SRCPV}"

SRCREV = "87e5eaf4707261dfcb37d7daadef018266c83d5a"

SRC_URI = "git://github.com/thp/pyotherside.git;branch=master;protocol=git \
           "
S = "${WORKDIR}/git/"

DEPENDS = "qtdeclarative python3 python3-native"
RDEPENDS_${PN} = "qtdeclarative-qmlplugins"

require recipes-qt/qt5/qt5.inc
------------------------------------------------------------------------


It is WIP, so e.g. the license is stil wrong.

The package depends on Qt5 and Python3.

I am currently experiencing two (rather small) problems:

1.) the configure step does not find "python3-config". It is located in
tmp/sysroots/i686-linux/usr/bin/python3-native

If I do a devshell and edit run.do_configure, I can add this path to the
PATH env variable, and then everything works.

How can I modify my recipe, so that this path is automatically added?

2.) The "python3-config" script just uses "#!/usr/bin/env python" to
define its interpreter, so the system starts the script with python2. If
I change the script manually, it works.

What would be the correct way to change my receipt to make it work? Or
would I need to change the python3 recipe to patch this file?

Thanks for your help!

Michael

P.S.: Seems, pyotherside is working nicely...

In that case, I would have expected to see 

inherit python3native qmake5 

in your recipe.

I haven't used python3 in combination with OE yet. Though, this should
likely have been handled by
inherit python3native

Cheers,

Great, that helped with no 1.). Still a lot to learn for me.

No 2. is still open, though. Is that a problem of my recipe or rather a
generic problem of the python3 recipe? I could patch the python3 recipe,
so that it changes the interpreter line to "python3".

Hmm the python3-native recipe has this install function:

----------------------------------------------------------
do_install() {
        install -d ${D}${libdir}/pkgconfig
        oe_runmake 'DESTDIR=${D}' install
        if [ -e ${WORKDIR}/sitecustomize.py ]; then
                install -m 0644 ${WORKDIR}/sitecustomize.py
${D}/${libdir}/python${PYTHON_MAJMIN}
        fi
        install -d ${D}${bindir}/${PN}
        install -m 0755 Parser/pgen ${D}${bindir}/${PN}

        # Make sure we use /usr/bin/env python
        for PYTHSCRIPT in `grep -rIl ${bindir}/${PN}/python
${D}${bindir}/${PN}`; do
                sed -i -e '1s|^#!.*|#!/usr/bin/env python|' $PYTHSCRIPT
        done
}
----------------------------------------------------------


If I change the sed line to "#!/usr/bin/env python3", that would
probably work then. But would it break something else?

would be fine.

Folks,

I'm trying to accomplish this in a 64bits host machine. But I'm getting
errors the following error on compile task:

| In file included from
/<snip>/tmp/sysroots/x86_64-linux/usr/include/python3.3m/Python.h:50:0,
|                  from ../../git/src/qpython_priv.h:22,
|                  from moc_qpython_priv.cpp:9:
| /<snip>/sysroots/x86_64-linux/usr/include/python3.3m/pyport.h:820:2:
error: #error "LONG_BIT definition appears wrong for platform (bad
gcc/glibc config?)."
|  #error "LONG_BIT definition appears wrong for platform (bad gcc/glibc
config?)."
|   ^


Searching on Google it says that this is a known bug when trying to
cross-compile Python stuff for 32bits machines on 64bits hosts.

It seems that the guys from Buildroot could get this solved:
http://lists.busybox.net/pipermail/buildroot/2011-August/045257.html
I'm trying to find the "magical" patch to how to get this fixed.

Also found this link too:
http://blog.devork.be/2009/02/compiling-32-bit-python-on-amd64.html

But I'm not quite sure how to get this fixed on Yocto. Should it need to be
fixed on the pyotherside, or python3, or python3-native recipe?


Any directions are appreciated.
