Debian Bullseye (testing) unable to compile kernel modules gcc version (null)

Jump to solution

I run Debian testing on most of my systems.  I recently upgraded my laptop to the latest patches including Linux Kernel 5.8.0.1.  This broke VMware player 15.5.6 (run workstation pro on my main machine).  I've been waiting for VMWare 16 since.  Now that it's out it won't compile the kernel modules citing it can't find a compatible gcc, but gives a null on which one it is looking for.  I know player/workstation is only designed to work with Debian 10, but I'm more than happy to find a workaround assuming I can figure out what it needs.

It seems to be more related to the kernel version rather than GCC and to the way vmware-modconfig (/usr/lib/vmware/bin/appLoader) retrieves information about Kernel GCC major version. I suspect the culprit is on extracting gcc version: note that from version gcc-10 we have 2 digit instead of 1 for the version number and in the logs we have  "GCC major version 10 does not match Kernel GCC major version 0." where 0 is the last digit of number 10.

Anyway, as user root you can manually compile the vmware host modules.

cd /usr/lib/vmware/modules/source

tar xvf vmnet.tar

cd vmnet-only

make

cd ..

tar xvf vmmon.tar

cd vmmon-only

make

cd ..

cp vmmon.o /lib/modules/`uname -r`/kernel/drivers/misc/vmmon.ko

cp vmnet.o /lib/modules/`uname -r`/kernel/drivers/misc/vmnet.ko

depmod -a

systemctl restart vmware.service

Thank you for posting your query in community. We are investigating it. And what is your gcc version by gcc --version ?

Also not working with gcc 10.

Any ideas? Is kernel under debian not compiled by gcc anymore?

gcc 10 is the main, but I've tried all 3 gcc versions installed.

$ gcc --version

gcc (Debian 10.2.0-7) 10.2.0

$ gcc-9 --version

gcc-9 (Debian 9.3.0-18) 9.3.0

$ gcc-8 --version

gcc-8 (Debian 8.4.0-4) 8.4.0

Probably add the kernel info

$ cat /proc/version

Thank you.  That did the trick and I suspect you may be right about the version number reaching double digits now.  Hopefully this will get patched soon, but the workaround is very easy to do.

Well now I don't seem to have any networking for my guest OS.  Attempted to update vmware-tools and it balked at that.  Problems downloading components.  Still checking the system though.

Turns out it's just the bridged networking that's broken, but I'm not sure how.  NAT networking works fine.

Finally figured it out.  In Bridged mode the settings seemed to have switched to auto-detect.  In this case I think it picks up the wired connection first which isn't currently in use.  If I switched the bridged to only use the wireless it works fine.  However bridged mode seems to cause my entire system to hang occasionally.  This has been happening during recent updates even in VMWare 15.x.  I can't replicate it reliably.  Sometimes opening a single webpage will hang it, other times downloading large files.  Interestingly enough, NAT mode never seems to hang.

At any rate your workaround works fine and there's still some quirks specific to my system that I need to work out.  Thanks again.

Any clues would be great.

This is not the solution. following these instructions you'll run into various compiler errors and warnings treatened as errors with Workstation 16.1.0 install.

  1. The compiler is found, but mentioned als version "0". Maybe VMware build in build searches the compiler, interpreting gcc-10 als compiler version 0?

Since there are no modules build, there is nothing to copy.

  • It is related to both: compiler (gcc-10) and kernel version.(uname -r: 5.10.0-4-amd64).

Meanwhile I've tried various solutions, but none gave me a working compile and a loadable module in tune.

 

BTW: VMware Workstation 16.1.0, Kernel: 5.10.0-4-amd64, gcc 10.2.1-6 on Debian Testing (Buster).
Same on Debian Stable, Ubuntu 20.10 (groovy), Ubuntu 21.04 (hirsuit), Fedora 33, 34, 35 (rawhide).

Looks like the old problem of redefining things already defined elsewhere ...

It seems to be an old thread, so the VMware shell script vmware-modconfig might have not existed at the time nor provided with the VMware installer. But now that it does, the vmmon and vmnet modules may be built from the same tarballs, with one command-line only, at least from Debian :

 

 

$ sudo /usr/bin/vmware-modconfig --console --install-all

 

 

As mentioned on https://kb.vmware.com/s/article/1002411  ; an additional step (module signing, using sign-file tool and your MOK key pair, as described on https://gist.github.com/gabrieljcs/68939c7eeadfabfdbc6b40100130270d ) might be required when using SecureBoot. I did not test it, though.
