Building vmware Linux modules rebuilds the complete kernel tree - what is wrong?


while trying to build the vmmon and vmnet modules, the build system rebuilds the complete kernel source tree instead of building just vmmon etc:

dell:/usr/lib/vmware/modules/source/vmmon-only # make

Using kernel build system.

make -C /lib/modules/5.4.13/build/include/.. SUBDIRS=$PWD SRCROOT=$PWD/. \


make[1]: Entering directory '/home/root/src/linux-5.4.13'

why is this happening? Same happens if you just run vmware or vmware-modconfig (and there is no module yet), it still rebuilds the complete kernel.

it actually never finish building it, terminates with error:

seems to me vmware Makefile is messing with the .config in the original Linux build directory and triggers a complete rebuild of the kernel?

Hello, is there a solution?

Thank you

Somewhere around kernel 5.0, Masahiro Yamada announced that support for long deprecated SUBDIRS variable would be removed "after 5.3". This happened in commit 7e35b42591c0 ("kbuild: remove SUBDIRS support") in 5.4-rc2 but VMware developers apparently didn't fix it before it actually broke.

However, this is not the only problem with 5.4 and newer kernel; you can use patched version of the modules from GitHub - mkubecek/vmware-host-modules: Patches needed to build VMware (Player and Workstation) host ...
