-9999 version gives same compilation error :(

I managed to use Genius G-Pen tablet with distro-provided aiptek driver in Natty, so there is an alternate driver at least for the G-Pens.

I have zero previous experience related to Xorg programming and I'm not really sure what I'm doing but I think I'm on the right track. The attached patch compiles fine, but segfaults :p It's published here so someone else can take it over and finish the job if I don't do it first.

now it works ;-)

@mnemoc , This patch works!
I've tried it in version 0.7.4 driver
Thanks!

@mnemoc - That patch doesn't apply to the latest wizardpen driver code, all hunks fail to apply. Can you check what's gone wrong with this code branch:

https://code.launchpad.net/~wizardpen-devs/wizardpen/trunk

As soon as I have a working branch, I'll update the ppa with the working natty driver.

$ rm -rf wizardpen
$ bzr branch lp:wizardpen
Branched 45 revision(s).
$ cd wizardpen
$ patch -p0 < ../wizardpen-abi12.patch.txt
patching file src/wizardpen.c
patching file src/wizardpen.h
$

applies just fine here :-/ I actually wrote it against bzr's trunk

I just did `bzr push lp:wizardpen` and "oops"... passed ;-)

Thanks Martin. I hope to not have damaged anything

Ah I must have applied the patch backwards, sorry about that!

Thanks for the push, I'm trying to make a dist now but it's got failures. Are you any good with auto tools? It could do with some attention to figure out why it won't build a dist any more.

OK no panic, got it sorted out and the fix is released as tarball and deb in the ppa. version 0.8.1

About autotools, I've used it but I'm not a fan... but ordered a book about it last week hoping to understand it one day ;-)

looking forward for a binary 0.8.1 in natty's ppa :-)
