Bug 476540 – sys-kernel/genkernel - kernel_outputdir ignored when copying kernel image to tmp dir with --no-install is set

• Product: Gentoo Hosted Projects
• Status: RESOLVED OBSOLETE

[Description Florian Eitel 2013-07-11 13:30:32 UTC]

Error Message:

cp: cannot stat ‘arch/x86_64/boot/bzImage’: No such file or directory
* ERROR: Could not copy the kernel binary to /data/datenhaufen/libvirt/genkerneltmp!

tried versions: 3.4.45.1 and 3.4.47 -- both fail

config:
TMPDIR="/data/datenhaufen/libvirt/genkerneltmp" # has write permissions!
INSTALL="no"

called with: --kernel-outputdir=/data/datenhaufen/libvirt/genkerneltest

Reproducible: Always

Steps to Reproduce:
1. use --no-install and custom --kernel-outputdir
2. call genkernel
3. error
Actual Results:  
cp: cannot stat ‘arch/x86_64/boot/bzImage’: No such file or directory
* ERROR: Could not copy the kernel binary to /data/datenhaufen/libvirt/genkerneltmp!

Expected Results:  
copy should work -> copy should search for binary in KERNEL_OUTPUTDIR not in /usr/src/linux/

In the file gen_compile.sh the function find_kernel_binary from gen_funcs.sh is called. This function cd into KERNEL_OUTPUTDIR and searches the binary. Then it cd's back to the old curdir (/usr/src/linux). Then if not isTrue CMD_INSTALL the function compile_kernel tries to copy the tmp_kernel_binary to the TMPDIR. But this is not working because the tmp_kernel_binary is "arch/x86_64/boot/bzImage" but the pwd is not the KERNEL_OUTPUTDIR. Instead it searches the binary at /usr/src/linux. But there it doesn't exists.

What can I do to fix this? Any authority I can sent a patch to? It is only a small change of probably one or two lines.

[Comment 3 Thomas Deutschmann (RETIRED) 2019-03-22 18:38:53 UTC]

From reading the source, the affected code wasn't changed within last 10 years. So I am not sure about

> TMPDIR="/data/datenhaufen/libvirt/genkerneltmp" # has write permissions!

Anyway, I cannot reproduce with latest genkernel git version. Please re-open if you are still able to reproduce.
