| # Building guacamole-server for Windows | ||
| The `guacamole-server` Windows build relies on compatibility features provided by Cygwin (most notably, a `fork()` implmentation), and therefore _must_ be built using Cygwin tools. Since no Cygwin cross-compilation environment exists, this means that `guacamole-server` can only be built for Windows using the Windows OS. This document describes a build that produces a working `guacd.exe`, as well as shared libraries for every supported protocol. | ||
| Certain portions of `guacamole-server` can be built using MinGW on Windows, specifically the libguac libraries. `guacd` itself relies on `fork()` and other functionality that has no equivalent in Windows. Theoretically, Cygwin could provide a compatibility layer for these missing functions, but so far attempts to implement such a build have not resulted in a functional `guacd`. | ||
|
|
||
| ## Build Specifics | ||
| In this example, `guacamole-server` was built under Cygwin, on a Windows Server 2022 x86_64 build node. Dependencies were installed using packages from Cygwin and MSYS2 (and built from source where no suitable package is available, in the case of `libtelnet` and `libfreerdp2`). | ||
| This document will walk you through a known-working set of steps for building the libguac libraries for a Windows target. The following build steps were tested on a Windows Server 2022 x86_64 build node. | ||

|
||
| ## Closing Notes | ||
| The generated `guacd.exe` will run as expected when invoked from the Cygwin bash shell, but when run outside of a Cygwin environment (e.g. using powershell), connections using text-based protocols (ssh, telnet, kubernetes) will fail with `Fontconfig error: Cannot load default config file`. | ||
|
|
||
| FIXME: Update this document to explain how to configure fonts under Windows once I figure it out. | ||
|
|
||
| In addition, to enable running `guacd.exe` outside of a Cygwin environment, all (non-system) DLLs that it depends on should be copied into the same directory as the executable. These can be found by running `ldd` in the Cygwin bash shell - e.g. | ||
| ``` | ||
| ldd /usr/local/sbin/guacd.exe | ||
| find /usr -name '*guac*.dll' | xargs ldd | ||
| ``` |
