# VMware Tools for Synology DSM
This is a port of the [open-vm-tools](https://github.com/vmware/open-vm-tools) implementation of VMware Tools to the [Synology DSM](https://www.synology.com/en-global/dsm) platform.
Here you will find ready-built binary installable `.spk`-packages for `Synology DSM`, together with the necessary sources, should you choose to build it yourself.
**Read this in other languages: | [English](README.md) |**
## open-vm-tools
`open-vm-tools` is a set of services and modules that enable several features in `VMware` products for better management of, and seamless user interactions with, guest operating systems.
Specifically, this port enables interaction with a virtualised `Synology DSM` running as a `VMware` guest VM. A typical host runs the `VMware ESXi` hypervisor.
`open-vm-tools` is open source software released under `GPL v2` and `GPL v2` compatible licenses.
More information can be found at the official [open-vm-tools source repository](https://github.com/vmware/open-vm-tools).
## Synology DSM Package (.spk) Files
`.spk`-packages are found under the Release section. SPK releases track `open-vm-tools` versions from the upstream project.
Filenames are in the form
```
open-vm-tools_[Arch]-[DSM ver]_[open-vm-tools ver]-[build].spk
```
`[Arch]` is the CPU architecture supported by the package. Use the correct one that matches the intended `Synology` hardware model. This can be found in the official [Synology knowledge base](https://www.synology.com/en-global/knowledgebase/DSM/tutorial/Compatibility_Peripherals/What_kind_of_CPU_does_my_NAS_have).
`[DSM ver]` is the minimum `Synology DSM` version supported by the package.
`[open-vm-tools ver]` is the `open-vm-tools` version matching the upstream releases.
`[build]` is the incremental build number. Get the latest available to benefit from more recent patches built from upstream hotfixes.
For example, to install `open-vm-tools 11.2.5` on a `Synology NAS` model `DS3615xs` (Package Arch: `Bromolow`) running `DSM 6.2`, download a package file named `open-vm-tools_bromolow-6.2_11.2.5-xx.spk` which supports `DSM` versions `6.2` and above.
## Build Tooling
Builds are created using the cross-compilation framework provided by the [spksrc project](https://github.com/SynoCommunity/spksrc) from SynoCommunity.
`spksrc` is open source software released under the `BSD` license.
More information, including instructions to build this and many other projects relying on `spksrc`, can be found at the official [SynoCommunity/spksrc source repository](https://github.com/SynoCommunity/spksrc).
## Compiling
Note: The `open-vm-tools` source data is not contained in this repository and you will not to have to download it manually as the required data will be downloaded on-the-fly while compiling.
The release builds provided here were compiled by using an `Ubuntu Desktop 20.04 LTS` VM on a `VMware Workstation Player 16` type 2 hypervisor.
If you want to compile `open-vm-tools` for `Synology DSM` by yourself, do the following on a `Ubuntu/Debian` (or similiar) system, according to the following example (`open-vm-tools 11.5.2` and `apollolake/DSM 6.2` architecture):
~~**1.** Download the desired official [open-vm-tools release](https://github.com/vmware/open-vm-tools/releases/):~~
~~`cd ~/Downloads`~~
~~`wget https://github.com/vmware/open-vm-tools/releases/download/stable-12.0.5/open-vm-tools-12.0.5-19716617.tar.gz`~~
**2.** Create a temporary working directory...
`mkdir -p ~/tmp/`
~~...and push the following three checksums of the downloaded package into a `.txt` file (which we will use later) by executing:~~
~~`shasum -a 1 ~/Downloads/open-vm-tools-12.0.5-19716617.tar.gz >> ~/tmp/checksums.txt`~~
~~`shasum -a 256 ~/Downloads/open-vm-tools-12.0.5-19716617.tar.gz >> ~/tmp/checksums.txt`~~
~~`md5sum ~/Downloads/open-vm-tools-12.0.5-19716617.tar.gz >> ~/tmp/checksums.txt`~~
~~Delete the `.tar.gz`-file:~~
~~`rm -rf ~/Downloads/open-vm-tools-12.0.5-19716617.tar.gz`~~
**3.** Install the following packages:
`sudo apt-get install docker.io moreutils`
**4.** Clone the official "SynoCommunity" `spksrc` Github repository:
`git clone https://github.com/SynoCommunity/spksrc ~/tmp/spksrc`
**5.** Download the official "SynoCommunity" `spksrc` docker image:
`sudo docker pull ghcr.io/synocommunity/spksrc`
(Note: do not pull `synocommunity/spksrc` as it is missing packages)
**6.** Clone the `open-vm-tools` build files:
`git clone https://github.com/AuxXxilium/synology-dsm-open-vm-tools.git ~/tmp/open-vm-tools`
~~**7.** Edit the following file which holds the according checksum files and replace all values with the previously generated checksums from `~/tmp/checksums.txt`:~~
~~`nano ~/tmp/open-vm-tools/cross/open-vm-tools/digests`~~
~~Save the file and quit the editor.~~
~~**8.** Edit the following file and customize the values for the variables `PKG_VERS` and `PKG_BUILD` according to the `open-vm-tools` version you want to compile:~~
~~`nano ~/tmp/open-vm-tools/cross/open-vm-tools/Makefile`~~
~~Save the file and quit the editor.~~
~~**9.** Edit the following file and customize the value for the variable `SPK_VERS` according to the `.spk`-package version you want to generate and, if you want (optional), also for the variables `MAINTAINER` and `CHANGELOG`:~~
~~`nano ~/tmp/open-vm-tools/spk/open-vm-tools/Makefile`~~
~~Save the file and quit the editor.~~
**10.** Copy the `open-vm-tools` build files into the original "SynoCommunity" `spksrc` repository:
`sudo cp -r ~/tmp/open-vm-tools/* ~/tmp/spksrc/`
add sponge
`sudo cp -r /usr/bin/sponge ~/tmp/spksrc/`
**11.** Run and prepare the `spksrc`docker image:
`sudo docker run -it -v ~/tmp/spksrc:/spksrc ghcr.io/synocommunity/spksrc /bin/bash`
`make setup`
**12.** Install missing package `sponge`
~~The official synocommunity/spksrc docker container is missing the binary sponge. You need to install that for the build to finish:
`apt update`
`apt install moreutils`
(there might be better ways to accomplish that, but this one works for me)~~
add sponge
`cp -r /spksrc/sponge /usr/bin/`
**13.** Compile:
`cd /spksrc/spk/open-vm-tools-12/ && make arch-apollolake-7.0`
Sidenote: Other common architectures could be:
`arch-bromolow-7.0`
or
`arch-broadwell-7.0`
or
`arch-x64-7.0`
Now quit the docker building environment:
`exit`
You can now find the compiled `.spk`-package here:
`~/tmp/spksrc/packages`
**14.** Install the compiled `.spk`-package on your `Synology DSM` system.
Done.
