[ptxdist] Update libusb-1.0

[ptxdist] Update libusb-1.0

[Martin Lammers]

Hi there,

we are using ptxdist 2012.03.0 with the Phytec iMX board. I develop some 
USB applications with my Ubuntu machine using libusb-1.0.16.
In the ptxdist menuconfig i can select the libusb-1.0 to install it on 
my target system. When i look at the rules files i see this is version 
1.0.8.
Also in the newest version of ptxdist is the same version.
Now my question, what is the right way to update the libusb to version 
1.0.18 and it is possible to do that without changing the ptxdist version?

Best regards,

Martin

There exists two libusb variants, the original one "libusb" [0] and
"libusb-x" [1] a fork of libusb.

The current version of libusb is 1.0.9 and we have indeed 1.0.8. I can
write a patch to bump this version but we have also a crazy patch for
libusb 1.0.8:

`cat patches/libusb-1.0.8/libusb-1.0.1-pkg-config.diff`
Subject: libusb needs librt and libpthread

Add missing dependencies.

Maybe this already fixed in mainline... I will check this.

If you want to use libusb-x you need to generate a new port of this. I
checked it and they using autotools as buildsystem so a new port would
be (hopefully) easy.

But it depends which library you want... libusb or libusbx.

Hi Alex,

thanks for the fast response. We want to use libusbx version 1.0.18.

Thanks for your help,

Then you need to write a new port of it. Look for the documentation at
[0], "4.2.1 Rule File Creation". Send the new rules added to ptxdist
with git send-email as patches, then we can talk about the new port and
hopefully get the libusbx mainline to ptxdist so other can use it also.

I don't have time right now to do the port myself, sorry.

Hi Alex,
thanks for the information.  On the ptxdist the version of libusb.org 
have the name libusb-1.x. When it build the name of the library file 
like libusb-1.0.a .la.
Now i want to create a new rule file for the libusbx versions witch had 
the same library name like libusb-1.0.a .la.
It is necessary to block the two versions each other ?

Now we had to check, if we get any problems with the update, because the 
libusb is used by some phytec tools.
It is ok, then we want to add the new rule files to ptxdist. I hope it 
works without any proplems :-).

Best regards
Martin

name the library LIBUSBX_...

Yes. LIBUSB should have depends on !LIBUSBX and LIBUSBX should have
depends on !LIBUSB. Maybe there exists a better solution, I don't look
much more into that.

This would end in problems yea, but then you need to change the
dependency of these tools to "select LIBUSBX". You don't should do that,
because these tools was developed for LIBUSB and not LIBUSBX.

You can't have LIBUSB and LIBUSBX installed, but maybe it's easy to port
it look at [0] in About.

"As far as the library binary and header are concerned, since libusb and
libusbx use the same names and have the same API, you just need to
replace your deployed libusbx files with the libusb ones. That's all!"

This makes all things much difficult... maybe we make a config option to
LIBUSB to decide if you want to have libusb or libusbx and change the
actually libusb rules. But this sounds like an hack, which remember me
about the gnu- and bsd-netcat rules. Another option would be to drop
libusb support and add libusbx support. But this is a question which
should answer by the ptxdist maintainer Michael Olbrich.

My opinion is that when all others distribution uses libusbx and not
libusb then we should also drop the libusb support and add libusbx for
that instead.

But remember what I already said, the "phytec tools" was developed for your
libusb and to the libusb version which is shipped out with your BSP, you
can maybe run into trouble with that and I don't want to make the phytec
people angry.

Hi Martin,

I just sent a patch to ptxdist to replace libusb to libusbx. Please try
and let me know your results if this works for you.

Hi Alex,

thanks for the rapid work. I try to install the patch and test it with 
my current project.
This can take a while, because we are still working with git but we 
never work with mailing lists an git patches.
I hope it is not so difficult to apply a patch and i find some 
information in the git documentation ;-)

ahh you don't have this stupid signature anymore that don't allow to
copy mails. That's much better now, because we can't provide that at
this mailinglist. :-)

If you have problems with that just ask... I can tell you about my mail
environment which allow me to easily grab patches from my mbox or I just
upload it... or just wait if Michael applied this patches and then you
can get the raw files from cgit web interface.

Here are the files, I uploaded it to pastie.org:

rules/libusb.in:
http://pastie.org/8981719

rules/libusb.make:
http://pastie.org/8981722

put these files in your BSP rules.

Cheers
Alex

Hi Alex,

i tried this patch with ptxdist 2012.03.0. It still works on my phyflex 
iMX6 board.
No problems with my ftdi2232 chips. Also the phytec touch driver works.

Thanks for your support.
I still interesting in your mail configuration.

I have in my .mutt/muttrc:

This allows me to press Ctrl-o,l and the patch in the currently selected
