Description Jan Vansteenkiste 2019-03-14 08:05:29 UTC 
Looks like there are some issues with the build environment while trying to compile the virtualbox-modules with a newer kernel (5.x) although upstream should support it since this release.

Manually going into the work folder and running the same make command, the compile goes through without issues.

Please attach the build.log file to this bug.
Comment 2 Jan Vansteenkiste 2019-03-14 09:14:16 UTC 
I tried uploading the build.log but I'm getting 

Software error:

Malformed multipart POST: data truncated

For help, please send mail to the webmaster (webmaster@gentoo.org), giving this error message and the time and date of the error. 

The build.log is actually pretty small so I can copy paste it here:

Small update: When I go to the work folder and run

make -j9 HOSTCC=x86_64-pc-linux-gnu-gcc CROSS_COMPILE=x86_64-pc-linux-gnu- 'LDFLAGS=-m elf_x86_64' CC=x86_64-pc-linux-gnu-gcc KERN_DIR=/usr/src/linux KERN_VER=5.0.3-gentoo O=/usr/src/linux V=1 KBUILD_VERBOSE=1 all

by hand, the compile goes through fine.

Related Problem on my System, but with other output.
Manually executing

works fine, $? is 0.


but compiling fails:

app-emulation/virtualbox-modules-6.0.6::gentoo was built with the following:
USE="-pax_kernel" ABI_X86="(64)"
Comment 11 Jan Vansteenkiste 2019-04-30 06:54:23 UTC 
For reference: I downgraded the linux-headers to the latest stable (4.14-r1) and it gives the same error.
Comment 12 Jan Vansteenkiste 2019-05-21 05:34:02 UTC 
This is still the case for virtualbox-modules-6.0.8
Comment 13 Jesús Guerrero 2019-08-10 07:18:00 UTC 
This happens for me as well, with latest vanilla kernel and app-emulation/virtualbox-modules-6.0.10
Comment 14 Xavier Fernández i Marín 2019-09-28 13:23:32 UTC 
Same with 6.0.12 here.
Comment 15 Xavier Fernández i Marín 2019-09-30 08:13:58 UTC 
I correct myself: trying it now with the new portage-2.3.76 solves the issue for me. So I would suggest to update portage to the new version.

I've been suffering this same issue for months now. That didn't help either. I agree this is something to do with the build environment. At some point I was able to build the thing against kernel 5.0.0, which now I can't. So I am stuck with kernel 5.0.0 and virtualbox 6.0.8.130520 which is no longer in the portage tree. 

Haven't had the time to check into the issue, but it's probably fixable in the ebuild without even patching the sources.

Just for the record, a user in #gentoo-de on freenode IRC had the same issue and it turned out to be /usr/src directory not having the correct permissions so user portage could read the content of /usr/src

Please make sure that the portage user can access all files below /usr/src/*

This was exactly my problem. /usr/src was set to 700. Not sure when/how that happened for me.
Comment 19 Viorel Munteanu gentoo-dev 2022-11-11 10:09:39 UTC 
I can reproduce this issue in v7.0.2 if I do not install the current kernel modules.  Please check the directories exist, are valid and have proper permissions:

ls -l /lib/modules/`uname -r`/build
ls -l /usr/src/linux

ls -l /lib/modules/`uname -r`/build/
ls -l /usr/src/linux/
