Bug 85410 – madwifi-driver build fails on using KBUILD_OUTPUT

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description White 2005-03-15 13:24:51 UTC]

Build fails on Using external build dir KBUILD_OUTPUT



Reproducible: Always
Steps to Reproduce:
1. Build Kernel with make O=external dir
2. export KBUILD_OUTPUT
3. emerge madwifi-driver

Actual Results:

johnm: Is this possible to implement with linux-mod?

White: Any idea how to fix it?

[Comment 2 John Mylchreest (RETIRED) 2005-04-14 03:47:52 UTC]

gthe problem with this one is here:

BUILD_PARAMS="KERNELPATH=${ROOT}${KV_DIR} KERNELRELEASE=${KV_FULL}
                TARGET=${TARGET} TOOLPREFIX=/usr/bin/"

KV_DIR = the srcdir, which is readlink -f /lib/modules/`uname -r`/source

for example. 
this isnt where the Makefile is kept, as the makefile is kept in KV_OUT_DIR

KV_OUT_DIR = the objdir, which is readlink -f /lib/modules/`uname -r`/build

can you please try changing that to ${KV_OUT_DIR} and testing.
if it works, please comment on this bug.
I will make the ebuild change now anyways, since it wont hurt for anyone not using KBUILD_OUTPUT
