I don't want to get into the middle of this. But the real issue here is that
there are problems with a commonly used library, libusb, that need to be
fixed. This is something that none of us has much control or influence over.
Graeme is doing what he believes is the right thing to do to insure that
ArgyllCMS works and I have followed the same path in some of my own work so I
can understand his point of view (I use a modified version of lcms that has a
mod that will not end up being available in the stock version). Frederic is
doing what he can to get the problem with the library fixed at least in the
context of the distro(s) he supports and many of his points are valid. In
some respects both are correct although I think we can get more done if we
work together rather than snipping at each other. After all we want ArgyllCMS
and the meter libraries to work correctly with the stock library and anything
we do that does not move things in that direction is counter productive.
Instead perhaps we can come up with a plan to get things fixed. One approach
would be to create a diffinitive patch or patch set for libusb and make this
available in a very visible place. Perhaps the patch Frederic created is that
patch? Once this is available all of us can open bug reports with our various
distro's asking them to apply that patch to libusb. If even one major distro
is using that patch (or patch set) then most other distros should start
picking up the patch without too much effort on our part. Since this has
already happened with fredora and Mandriva then it is mostly a matter of
getting other distros to start using this patch. When most of the major
distros are using this patch perhaps at that point the libusb folks will see
the light and create a version that has been fixed. In the mean time most of
us running Linux platforms will be using distros that have a version of libusb
that has been fixed. Once that starts happening the Argyll build could
prehaps check to see if a patched version is installed and use the shared (but
patched) version rather than building with the built in version of libusb.
Frederic can you provide a link to the libusb patch(es)? Has anyone verified
that this patch does indeed fix the i1 pro issues in particular? Graeme are
there any other devices that will have problems if runing agaist an unpatched
libusb? I have tested the i1 display 2/Lt, Huey and Spyder 2 with stock
libusb and these are OK but I would be mroe than ahppy to test these using
this new set of patches. Frederic if you can provide a link to the patch(es)
I will open a bug report with my distro (gentoo) and perhaps others here can
do the same thing. This is the correct approach to this issue. Users put
pressure on the distros to get it fixed and the distros put pressure on the
library maintainers.
I should also point out that although ArgyllCMS has not been packaged on many
distros LProf has been a standard package on many distros for a long time and
the next release of LProf will be using the ArgyllCMS meter libraries. So
even if your distro does not have an ArgyllCMS package you can point to LProf
as something that will need this in the near future. That is this in not just
about ArgyllCMS.
