Subject: [oe] Understanding recipes vs packages
Hello
Something very weird is going on with some changes I have made recently to a
custom image I am building.
For some reason I was getting libpng12 built and now that no longer happens.
In debugging this I've been doing things that now stump me.
From my understanding, a recipe can build multiple different packages.
For example libpng.inc has the following in it:
Yes, it is correct.
PACKAGES =+ ${PN}12-dbg ${PN}12 ${PN}12-dev
FILES_${PN}12-dbg += ${libdir}/libpng12*.dbg
FILES_${PN}12 = ${libdir}/libpng12.so.*
FILES_${PN}12-dev = ${libdir}/libpng12.* ${includedir}/libpng12
${libdir}/pkgconfig/libpng12.pc
FILES_${PN} = ${libdir}/lib*.so.*
FILES_${PN}-dev = ${includedir} ${libdir}/lib*.so ${libdir}/*.la \
${libdir}/*.a ${libdir}/pkgconfig \
${datadir}/aclocal ${bindir} ${sbindir}
Does that mean I should be able to build libgpng12 as follows:
bitbake libpng12
No, package name could not be passed to bitbake as a parameter.
Bitbake can accept a recipe name as its parameter, and it will process tasks
like do_fetch, do_unpack, ..., do_package, etc. for that recipe. In the
above case, libpng12 will be generated in do_package task, and then it will
be archived into rpm/ipk/deb package formats.
Try to run bitbake libpng and see if libpng12 is generated.
Yes it is.
OK thanks for the clarification
So if I want to put the libpng12 in an image then do I need to do
something like:
# Add libpng to DEPENDS to get the recipe to build
# Add libpng12 to IMAGE_INSTALL because that's what I want in the package
DEPENDS += libpng
IMAGE_INSTALL += libpng12

Re: [oe] Kernel boot problems
Hi Gary, Did as you suggested .. no printout from serial_imx_probe() is seen, so I guess it isn't been called, will have to trace it back to see why not. This is going to be tedious .. EDIT: However the function imx_serial_init() is being called and completes without errors, so I don't know why the probe is not being called .. Any ideas? The serial initialisation probably happens twice: Once for the early console stuff to give to the tracing before the uncompressing. Then again for setting up the real device tree when the decompressed kernel is being booted. I think the probing is only during the second.

What toolchain are you building?
If you build meta-toolchain that should build all the stuff you can put into
/usr/local/angstrom/arm/... which includes gdb.
That should then work with a JTAG debugger etc.

Hi Charles,

You can run but you can't hide.
I have built for the angstom distro (arm-angstrom-linux-gnueabi-*), but the
tools got put in my project path I described in my earlier email, but
There was no GDB included for some reason ..
The regular toolchian than oe builds for its own purposes does not use
gdb because gdb is not needed for building. That toolchain is intended
for use within OE bitbakery only.
A meta-toolchain is built as a standalone toolchain intended for use
outside of OE (eg. if you pull u-boot to a standalone directory for
development purposes or want to do your own app development outside of
OE.)
How do you build the meta-toolchain, and how will that help.
bitbake meta-toolchain.
This makes a toolchain which you can unpack thus:
$ cd /
$ sudo tar xvjf
${OETOP}/tmp/deploy/glibc/sdk/angstrom-2009.X-test-20110301-armv7a-linux-gnueabi-toolchain.tar.bz2
[NB your toolchain name will be something different]
To set up all the paths etc use
. /usr/local/angstrom/arm/environment-setup
Google openembedded metatoolchain will also give some interesting info.
NB If you're building apps and need extra libraries you will need to
make your own SDK. That's a bit more effort and you don't need all
that just for gdbing u-boot

[oe] How do I install python modules for use within recipes?
Hi
I have a project which uses python as part of the building process to
generate some C code from some XML which is then later compiled.
The python script uses the python lxml module.
My recipe has a do_compile as follows:
do_compile() {
cd ${S}/
make -f Gencode.mk
make
}
During the make -f Gencode.mk, the python script which imports lxml
fails to do so and fails.

available here?

I don't see a recipe for python-lxml-native, so you'll likely have to make
one (and then make your recipe depend on it to ensure it's built and
available).
There are several other python-*-native modules in OE, take a look at what
they're doing.

No, that's for the internal Python modules.

Sorry I don't usually use gmail web interface...
So by Internal Python modules what do you mean? If that's just the
stuff used in cranking bitbake and OE then why does it need to
generate the manifest in the recipes?
Building some python modules from scratch looks ugly. Is there
anything stopping me from just using easy-install? ... Or would that
be even harder? Seems odd that native recipes don't use easy-install
unless there is a good reason not to.

${WORKDIR}/foo/Common
