<br>
I'm one of the SANE developers and am trying to get rid of all compiler<br>
warnings on a select subset of build environments. Alpine Linux is one<br>
of them and its parallel port IO support is giving me a bit of trouble.<br>
Hope you can help me out a bit.<br>
<br>
I don't see any libieee1284 packages for 3.6. Is there any activity to<br>
add libieee1284? It would enable support for a few more backends.<br>
<br>
A few backends also provide parallel port IO support if certain Linux<br>
kernel headers are present. Looking at the `makedepends` list in the<br>
sane package's APKBUILD file, I don't see kernel-headers listed. Can<br>
I assume that the Alpine package build environment makes sure that is<br>
present? If not, you may want to add it. It would make at least the<br>
umax_pp backend do something more useful. Without that package, it<br>
compiles but essentially just no-ops just about all the I/O after<br>
spitting out a warning, IIUC.<br>
<br>
My builds have so far not included the kernel-headers package in the<br>
list of packages to be installed but I'm leaning towards adding it. It<br>
would solve a major compiler warning headache for me ;-)<br>
<br>
If Alpine Linux' default build environment always includes it, I feel<br>
more justified to "take the easy way out".<br>
<br>
You can find my build environment setup[1] as well as build logs[2] (the<br>
middle stage, first on the drop-down list) over at GitLab.com.<br>

<br>
Somewhat off-topic, but ...<br>
<br>
I also see that you list the license as GPL in the APKBUILD file. Is<br>
that for that file only or does that apply to the binary packages?<br>
If the latter, it's not correct and really should be fixed.<br>
<br>
BTW, love the fact that you provide a package per backend! Wishing<br>
other distributions would do the same.<br>
<br>
Thanks for any feedback in advance,<br>
