I did... or so I thought.. will try tomorrow and give you feedback!

@funkmuscle The output shows that you didn't remove src directory from previous build as I indicated previously. Please add -C argument to makepkg (capital C) so it doesn't try to apply patch to source files that were already patched.

@funkmuscle I didn't make any changes to arch/parisc/lib/fixup.S at all for r3. Can you provide the full PKGBUILD and output?

funkmuscle commented on 2018-08-14 02:49

yep.. built the first time after your help.. now trying to get r3 and that where I'm getting the error

net147 commented on 2018-08-14 02:31

@funkmuscle Works for me. Did you remove the pkg and src directories before building?

funkmuscle commented on 2018-08-14 00:56

getting this now: can't find file to patch at input line 217560 Perhaps you used the wrong -p or --strip option? The text leading up to this was:

|diff --git a/arch/parisc/lib/fixup.S b/arch/parisc/lib/fixup.S |index 1052b747e011..a5b72f22c7a6 100644 |--- a/arch/parisc/lib/fixup.S |+++ b/arch/parisc/lib/fixup.S

File to patch:

net147 commented on 2018-08-13 22:06

@funkmuscle It should still compile properly for patch releases (third number in the Linux version). So if there are no interesting changes in sound/usb then it isn't necessary to adjust for every patch release. I have updated the package to r3 to improve stability at the cost of around 8 additional samples of round trip latency at 48 KHz 24-bit.

funkmuscle commented on 2018-08-13 17:55

@net147 thanx bud, it worked. will this need to be adjusted as the kernel up grades?

net147 commented on 2018-08-13 12:10

@funkmuscle The PKGBUILD needs to be modified to match your kernel version:

  1. Replace 4.17.14 with 4.9.84

  2. Replace 4.17 with 4.9

  3. Run "updpkgsums"

  4. Run "makepkg -Cis"
