# Known issues
|
|
|
|
If you're trying the commands [on the homepage](https://hexops.com/mach/) and running into issues, it may be one of these known issues.
|
|
|
|
## Windows: File not found
|
|
|
|
If you encounter an error like this:
|
|
|
|
|
|
|
|
Windows does not have symlinks enabled, or Git is not configured to use them. This is very annoying and [has been reported to Microsoft](https://twitter.com/slimsag/status/1508114938933362688).
|
|
|
|
**Two solutions:**
|
|
|
|
1. (recommended) Build a native Windows binary by cross-compiling from WSL -> Windows:
|
|
* `cd mach/gpu`
|
|
* `zig build -Dtarget=x86_64-windows`
|
|
* Run the exe in `zig-out/bin/` outside of WSL.
|
|
2. Enable symlinks in Windows:
|
|
* [Turn on Development Mode](https://docs.microsoft.com/en-us/windows/apps/get-started/enable-your-device-for-development)
|
|
* [Ensure symlinks are installed in Git](https://stackoverflow.com/a/59761201) `git config --global core.symlinks true`
|
|
* Re-clone the repository and try again.
|
|
|
|
## Windows: "SSL certificate problem: unable to get local issuer certificate"
|
|
|
|
This is a curl SSL CA issue, you may want to Google for proper solutions on your system. That said, you can `set CURL_INSECURE=true` and retry to disable SSL verification if you want to workaround the issue.

## Linux: `Error: Couldn't load Vulkan. Searched /tmp/mach/gpu/zig-out/bin/libvulkan.so.1`
|
|
|
|
We're aware of a bug failing to find `libvulkan.so` on some Linux distros such as [Guix](https://guix.gnu.org/).
|
|
|
|
```
|
|
Error: Couldn't load Vulkan. Searched /tmp/mach/gpu/zig-out/bin/libvulkan.so.1, /tmp/mach/gpu/zig-out/bin/libvulkan.so.1, libvulkan.so.1.

|
|
```
|
|
|
|
This is [a bug in Dawn](https://github.com/NixOS/nixpkgs/issues/150398), you can workaround it for now by specifying the path to `libvulkan.so` on your system `LD_PRELOAD` like e.g.:
|
|
|
|
```
|
|
LD_PRELOAD=/run/current-system/profile/lib/libvulkan.so zig-out/bin/gpu-hello-triangle
|
|
```
