Requirements and Dependencies​

WasmEdge requires LLVM 13 and you may need to install these following dependencies by yourself.

  • Chocolatey, we use it to install cmake, ninja, and vswhere.
  • Windows SDK 19041
  • LLVM 13.0.1, you can find the pre-built files here or you can just follow the instructions/commands to download automatically.
# Install the required tools
choco install cmake ninja vswhere

$vsPath = (vswhere -latest -property installationPath)
Import-Module (Join-Path $vsPath "Common7\Tools\Microsoft.VisualStudio.DevShell.dll")
Enter-VsDevShell -VsInstallPath $vsPath -SkipAutomaticLocation -DevCmdArguments "-arch=x64 -host_arch=x64 -winsdk=10.0.19041.0"

# Download our pre-built LLVM 13 binary
$llvm = "LLVM-13.0.1-win64.zip"
curl -sLO https://github.com/WasmEdge/llvm-windows/releases/download/llvmorg-13.0.1/LLVM-13.0.1-win64.zip -o $llvm

Run Tests​

The following tests are available only when the build option WASMEDGE_BUILD_TESTS was set to ON.

Users can use these tests to verify the correctness of WasmEdge binaries.

$vsPath = (vswhere -latest -property installationPath)
Import-Module (Join-Path $vsPath "Common7\Tools\Microsoft.VisualStudio.DevShell.dll")
Enter-VsDevShell -VsInstallPath $vsPath -SkipAutomaticLocation -DevCmdArguments "-arch=x64 -host_arch=x64 -winsdk=10.0.19041.0"

$Env:PATH += ";$pwd\\build\\lib\\api"
cd build
