There are a few changes in glibc-2.10 that might make your software fail to build with it, please refer to my blog post [1] if you're not sure what the problem is. Also make sure to fix it rather than sidestepping the issue [2]. And no I don't usually provide emerge --info with these bugs because they are caused by glibc-2.10! Thanks, Diego [1] http://blog.flameeyes.eu/2009/05/24/c-libraries-galore [2] http://blog.flameeyes.eu/2009/07/02/how-_not_-to-fix-gcc-4-4-bugs
Created attachment 197083 [details] Build log
Can't reproduce with GCC 4.4.1 and GLIBC 2.10.1.
Samuli, do I remember you using amd64? I think this package have very different behaviour between the two arches.

*** Bug 280297 has been marked as a duplicate of this bug. ***
Please, keep it in portage. That is the only way to get "supported" many scanners under sane. Sane devs do not maintain all kind of drivers, and this package provides supports for many devices. Please commit the patches in bug #248898 (more recent versions of the package) to the tree and you can immediately close my bug #280297 (reporting that the in-tree, outdated version cannot be compiled). In my case, Epson PerfectionV10 scaner is supported by the iscan package (epkowa driver). See http://www.sane-project.org/lists/sane-mfgs-cvs.html .

I'll see if I can fix this before going on vacation, I'd also like for this _not_ to go (although I would split it up in iscan and iscan-firmware, then iscan I wouldn't care ;P)… one of my scanners use this.
Created attachment 201185 [details, diff] Patch to fix glibc-2.10 compilation failure Only compilation on x86 was tested.
Created attachment 201186 [details, diff] Fix pointer arithmetic of previous patch Sorry, the wrong pointer arithmetic was a consequence of non-testing; and it means I am just too tired now - I hope that I made no further mistake.
Thanks for the patch! I tested and worked fine here btw the next step should be bumping version, bug 248898
