VMWare Workstation vmmon broken on Ubuntu 18.04

I found a solution and create a script file based on mkucebek's github sources.

You must create a file with this content and run it each time it's needed :

#!/bin/bash
VMWARE_VERSION=workstation-12.5.9
TMP_FOLDER=/tmp/patch-vmware
rm -fdr $TMP_FOLDER
mkdir -p $TMP_FOLDER
cd $TMP_FOLDER
git clone https://github.com/mkubecek/vmware-host-modules.git
cd $TMP_FOLDER/vmware-host-modules
git checkout $VMWARE_VERSION
make
sudo make install
sudo rm /usr/lib/vmware/lib/libz.so.1/libz.so.1
sudo ln -sv /lib/x86_64-linux-gnu/libz.so.1 /usr/lib/vmware/lib/libz.so.1/libz.so.1
sudo /etc/init.d/vmware restart

Then, you just have to launch VMware Workstation without building modules.

Using Charly's suggested script, I was able to build the needed modules for kernel 4.15.0-29-generic on 16.04 LTS. There is a typo at the end of the script, there should not be a line return between sudo ln -s /lib/x86_64-linux-gnu/libz.so.1 and /usr/lib/vmware/lib/libz.so.1/libz.so.1

Another addition I would recommend is to add sudo /etc/init.d/vmware restart command to the end of the above script.

So the actual solution script with tweaks is:

#!/bin/bash
VMWARE_VERSION=workstation-12.5.9
TMP_FOLDER=/tmp/patch-vmware
rm -fdr $TMP_FOLDER
mkdir -p $TMP_FOLDER
cd $TMP_FOLDER
git clone https://github.com/mkubecek/vmware-host-modules.git
cd $TMP_FOLDER/vmware-host-modules
git checkout $VMWARE_VERSION
git fetch
make
sudo make install
sudo rm /usr/lib/vmware/lib/libz.so.1/libz.so.1
sudo ln -s /lib/x86_64-linux-gnu/libz.so.1 /usr/lib/vmware/lib/libz.so.1/libz.so.1
sudo /etc/init.d/vmware restart

```

Sorry this isn't a comment on Charly's answer, I don't have the reputation on this account.

Note that this will only work for Workstation 12.5.9, you can easily tell which version you have by running vmware --version
