Help required to create recipe for FANN library

Help required to create recipe for FANN library

[Elvis Dowson]

Hi,
	Would someone be able to help us create an oe bitbake recipe for the  
Fast Artificial Neural Network Library ?

We have created an initial recipe, but the problem is don't know how  
to get this recipe to configure and install the library for the  
gumstix overo board.

If I look at the logs, nothing got configure or compiled when I look  
at the logs in the overo-oe/tmp/work/armv7a-angstrom-linux-gnueabi/ 
libfann-2.0.0-r01/tmp folder.

I've looked at a couple of recipes and it all looks the same, so can't  
figure out why this particular library is unable to get configured or  
built.

Any help would be much appreciated!

Best regards,

Elvis

Why are you using autotools_stage if you're not going to use its staging 
method?

I don't know these command. Could you help me correct this recipe?

The "inherit autotools_stage" provides the do_stage method. Remove the 
do_stage method and see what happens.

Hi Philip,

Could you try the recipe at your end?

Try setting the S variable in the recipe.

I tried this, it didn't work, still gave the same error because the  
image folder is empty so there is nothing to install. When I look at  
the log files, nothing got configured and nothing got compiled. This  
is a strange one!! :-)

It worked. I set the S variable wrong. The correct one is

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

I'm attaching the working recipe below.

Hi,
	When building the FANN library, I get the following message:

NOTE: Multiple libraries (libfann.so.2, libdoublefann.so.2,  
libfixedfann.so.2, libfloatfann.so.2) found and LEAD_SONAME not defined

What is the use of the LEAD_SONAME?

What should I do to make this recipe better and fix the following  
messages:

NOTE: Not creating empty archive for libfann-doc-2.0.0-r01.2
NOTE: Not creating empty archive for libfann-locale-2.0.0-r01.2

You should probably ignore LEAD_SONAME; this mechanism seemed like a
good idea at the time but with hindsight it was not such a clever plan.
The right way to fix this warning is to put each of the libraries in its
own output package.

Do you have a hint on how to do that? I've had the same question.

Right now, I think the only way is to do it by steam, something like:

PACKAGES =+ "libfann libdoublefann libfixedfann libfloatfann"
FILES_libfann = "${libdir}/libfann${SOLIBS}"
FILES_libdoublefan = "${libdir}/libdoublefan${SOLIBS}"
...

You can leave the -dev bits alone, it doesn't really hurt for them to go
into one big package.

Obviously there's some scope for automating this a bit: it'd be nice to
be able to just say

PACKAGE_SHLIBS = "libfann libdoublefann libfixedfann libfloatfann"

and have the other stuff be generated automatically.  That'd probably be
a fairly straightforward patch to package.bbclass if someone wanted to
have a go.

In an OpenEmbedded world with new variables appearing at a weekly
rate, let's try to clean out those who were a bad idea in hindsight
:-)

If there is consensus on this (and this is reviewed by a few core
people) how about we do some refactoring to clean things up and have
LEAD_SONAME removed?

That would be nice: it'd be a bonus for the micro distribution in
particular.  Unfortunately, there are quite a few packages using it, and
it's moderately hard to eliminate without breaking backwards packaging
compatibility so this would be a fair amount of work.  Most notably,
both uclibc and glibc are currently blighted by its presence so almost
every distribution would be affected by that kind of change.

I did as you suggested but get the following errors:

Hi,
	How can I get all the headers for the fann library to appear in $ 
{STAGING_INCDIR}/libfann

right now all the headers are located in ${STAGING_INCDIR} which  
corresponds to overo-oe/tmp/staging/armv7a-angstrom-linux-gnueabi/usr/ 
include  on my machine.

If your recipe itself is named "libfann" then it will appear in PACKAGES
automatically (as ${PN}); you don't need to add it explicitly.
