VMware GCC 9.2.1

"It still gives the error"

Which error? Please provide the full text.

"Before you can run VMware, several modules must be compiled and loaded into the running kernel.
GCC
GNU C Compiler (gcc) version 9.2.1 was not found. If you installed it in a non-default path you can specify the path below. Otherwise refer to your distribution's documentation for installation instructors and click Refresh to search again in default locations."
There is a box marked 'Location:' it appears to take text, and some buttons "Install", "Cancel", "Refresh", and "Brose"

"Brose"

"Brose" should be "Browse"

I have already installed gcc and build-essential

For diagnostic purposes, what is the output of the commands

uname -a
lsb_release -crid
apt-cache policy gcc-9
gcc --version

Maybe you have to use a different PPA for a sufficiently high version of the compiler, eventually ppa:jonathonf/gcc-9.2

I reduced the kernel version from 5.3.4 to 5.0.0-32 and it all went well. Maybe the kernel versions are dodgy, and they refer to an unreleased version of gcc.

FWIW here are the answers to your questions:

thanks, I found this bug when I needed gcc9.2.1 for vmware 15.1 on kernel 5.3.12 so it helped me compile the vmmon module from https://github.com/mkubecek/vmware-host-modules (thanks for the gcc ppa repo name!)

all worked fine on this config:
