Build Gateway Msi

Build Devolutions Gateway MSI Locally

Required Tools

• MSBuild — VS 2022: C:\Program Files\Microsoft Visual Studio\18\Community\MSBuild\Current\Bin\MSBuild.exe
• Rust/cargo
• pnpm — for building the web app
• PowerShell 7+ (pwsh)
• dotnet — for the PowerShell module build

Important Notes

• Static CRT is required for CI-matching builds. Without +crt-static, the binary fails at runtime with exit code -1073741515 (0xC0000135, DLL not found) on machines without the MSVC redistributable. Always set $Env:RUSTFLAGS = "-C target-feature=+crt-static" before cargo build --release. For a local debug build this is optional, but release builds must use it.

• Version stripping. The MSI product version must have a major component < 256, so the century prefix 20 must be stripped: 2026.1.0 → 26.1.0. This matches what ci/Build/Build.psm1 does via $version.Substring(2).

• MSBuild output filename. MSBuild writes Release\DevolutionsGateway.msi. Rename it to the versioned form if needed for distribution.

• Web app build is slow (~5-10 min). Skip it on repeated builds by reusing the existing webapp\dist\ output; only rebuild if webapp source changed.

• download-cadeau.ps1 runs from ci/ and always writes to ../native-libs/, which resolves to the repo root's native-libs\ directory. The file you need is native-libs\xmf.dll.

Step 1 — Build Rust Binary

cd D:\devolutions-gateway
$Env:RUSTFLAGS = "-C target-feature=+crt-static"  # required for CI-matching release build
cargo build --release -p devolutions-gateway
# Output: target\release\devolutions-gateway.exe

For a quick local debug build (no static CRT required, faster):

cd D:\devolutions-gateway
cargo build -p devolutions-gateway
# Output: target\debug\devolutions-gateway.exe

Step 2 — Download Cadeau (xmf.dll)

cd D:\devolutions-gateway
pwsh ci/download-cadeau.ps1 -Platform win -Architecture x64
# Output: native-libs\xmf.dll

Step 3 — Build PowerShell Module

cd D:\devolutions-gateway
pwsh powershell/build.ps1
# Output: powershell\package\DevolutionsGateway\

Step 4 — Build Web App

@devolutions/* packages are hosted on a private JFrog Artifactory registry. Before running pnpm install for the first time, configure authentication:

1. Log in: npm login --registry=https://devolutions.jfrog.io/devolutions/api/npm/npm/
2. Add these lines to %USERPROFILE%\.npmrc (they won't be added by npm login automatically):

   @devolutions:registry=https://devolutions.jfrog.io/devolutions/api/npm/npm/
   registry=https://registry.npmjs.org
   //devolutions.jfrog.io/artifactory/api/npm/npm/:_authToken=<same token as above>
   

   The third line is needed because the lockfile contains some package tarballs at /artifactory/ paths (different from /devolutions/), so a second token entry is required.

Then build:

cd D:\devolutions-gateway\webapp
pnpm install

# Build in dependency order: shadow-player → multi-video-player → apps
pnpm --filter '@devolutions/shadow-player' build       # packages/shadow-player
pnpm --filter '@devolutions/multi-video-player' build  # packages/multi-video-player (depends on shadow-player)
pnpm --filter './apps/gateway-ui' build
pnpm --filter './apps/recording-player' build          # depends on multi-video-player and shadow-player
# Outputs:
#   webapp\dist\gateway-ui\
#   webapp\dist\recording-player\

Note: pnpm build:libs and pnpm build:apps may report "No projects matched" depending on pnpm version/workspace state. Use the explicit --filter commands above instead.

Step 5 — Build the MSI

cd D:\devolutions-gateway\package\WindowsManaged

$msbuild = "C:\Program Files\Microsoft Visual Studio\18\Community\MSBuild\Current\Bin\MSBuild.exe"
$base = "D:\devolutions-gateway"

# Point at release binary (or replace with target\debug\devolutions-gateway.exe for debug build)
$Env:DGATEWAY_EXECUTABLE     = "$base\target\release\devolutions-gateway.exe"
$Env:DGATEWAY_LIB_XMF_PATH   = "$base\native-libs\xmf.dll"
$Env:DGATEWAY_PSMODULE_PATH  = "$base\powershell\package\DevolutionsGateway"
$Env:DGATEWAY_WEBCLIENT_PATH = "$base\webapp\dist\gateway-ui"
$Env:DGATEWAY_WEBPLAYER_PATH = "$base\webapp\dist\recording-player"
$version = (Get-Content "$base\VERSION" -Raw).Trim()
if ($version.StartsWith("20")) { $version = $version.Substring(2) }  # strip century: 2026.1.0 → 26.1.0
$Env:DGATEWAY_VERSION = $version

& $msbuild DevolutionsGateway.sln /t:clean,restore,build /p:Configuration=Release /verbosity:minimal

Output: package/WindowsManaged/Release/DevolutionsGateway.msi

Optionally rename to a versioned filename and compute the SHA-256:

$msi = "D:\devolutions-gateway\package\WindowsManaged\Release\DevolutionsGateway.msi"
$versioned = "D:\devolutions-gateway\package\WindowsManaged\Release\DevolutionsGateway-x86_64-20$($Env:DGATEWAY_VERSION).0.msi"
Copy-Item $msi $versioned -Force
$hash = (Get-FileHash $versioned -Algorithm SHA256).Hash
$hash | Set-Content "$([System.IO.Path]::ChangeExtension($versioned, 'sha'))"

Alternative — Use the Packaging Script

The ci/package-gateway-windows.ps1 script sets env vars and runs MSBuild for you:

$base = "D:\devolutions-gateway"
New-Item -ItemType Directory -Force -Path "$base\output\msi" | Out-Null

pwsh "$base\ci\package-gateway-windows.ps1" `
  -Exe        "$base\target\release\devolutions-gateway.exe" `
  -LibxmfFile "$base\native-libs\xmf.dll" `
  -PsModuleDir "$base\powershell\package\DevolutionsGateway" `
  -WebClientDir "$base\webapp\dist\gateway-ui" `
  -WebPlayerDir "$base\webapp\dist\recording-player" `
  -OutputDir  "$base\output\msi"
# Copies MSI to output\msi\DevolutionsGateway.msi

Note: the script requires MSBuild.exe to be on $Env:PATH. If it isn't, prepend it:

$Env:PATH = "C:\Program Files\Microsoft Visual Studio\18\Community\MSBuild\Current\Bin;$Env:PATH"

Installing the MSI

Always install with administrator rights. Double-clicking from Explorer runs the installer under an impersonated (non-elevated) token, which causes Error code 5 or silent failures in custom actions.

Install from an already-elevated PowerShell prompt:

# Option 1 — msiexec with log (recommended for debugging)
msiexec /i "C:\path\to\DevolutionsGateway.msi" /l*v "C:\path\to\log.log"

# Option 2 — silent install
msiexec /i "C:\path\to\DevolutionsGateway.msi" /quiet

Common Build Failures

Missing WixSharp.wix.bin NuGet Package

error MSB4018: The "MSBuild" task failed unexpectedly.

cd D:\devolutions-gateway\package\WindowsManaged
dotnet add package WixSharp.wix.bin --prerelease

0xC0000135 / Exit Code -1073741515 at Runtime

The binary was built without static CRT. Rebuild with $Env:RUSTFLAGS = "-C target-feature=+crt-static" (see Step 1). This matches CI and eliminates the dependency on the MSVC redistributable.

DGATEWAY_EXECUTABLE Not Found

Program.cs checks that the file exists at MSBuild time. Ensure cargo build completed successfully and the path in $Env:DGATEWAY_EXECUTABLE is correct (debug vs. release).

DGATEWAY_PSMODULE_PATH Not Found / Empty

Run pwsh powershell/build.ps1 first. The output directory is powershell\package\DevolutionsGateway. If the build fails due to a missing NuGet source, the script adds api.nuget.org automatically; ensure internet access or restore from cache.

DGATEWAY_WEBCLIENT_PATH / DGATEWAY_WEBPLAYER_PATH Not Found

Run pnpm install && pnpm build:libs && pnpm build:apps in webapp/. Both gateway-ui and recording-player must exist under webapp\dist\ before the MSI build starts.

pnpm install Fails with ERR_PNPM_FETCH_404 for @devolutions/icons

@devolutions/icons is a private package not available on the public npm registry. It requires access to a private npm registry (JFrog Artifactory). Fix:

1. Log in: npm login --registry=https://devolutions.jfrog.io/devolutions/api/npm/npm/
2. Append to %USERPROFILE%\.npmrc:

   @devolutions:registry=https://devolutions.jfrog.io/devolutions/api/npm/npm/
   registry=https://registry.npmjs.org
   //devolutions.jfrog.io/artifactory/api/npm/npm/:_authToken=<same token as the /devolutions/ line>
   

   The /artifactory/ token entry is needed because some packages in the lockfile resolve to that URL path rather than /devolutions/.

pnpm build:libs / pnpm build:apps — "No projects matched"

Use explicit --filter calls instead (see Step 4). The glob filters in package.json scripts may not resolve depending on pnpm version.

The workspace library packages (shadow-player, multi-video-player) are in packages/ and must be built before the apps that consume them. Build order: shadow-player → multi-video-player → gateway-ui and recording-player.
