Platforms, licence, and where everything lives.
Platform support
The compiler, the CLI, the language server and the runtime are pure Java 25. There is no native code, no JNI, no shell-out and nothing to port: anywhere a JDK 25 runs, V# runs, on any architecture that the JDK supports.
| Host | Compiler · CLI · LSP | Gradle plugin | Native image (GRAAL_HOME) |
Get a JDK 25 |
|---|---|---|---|---|
| Linux (glibc) | ✓ | ✓ | ✓ | apt install openjdk-25-jdk · dnf install java-25-openjdk |
| Linux (musl / Alpine) | ✓ | ✓ | ✓ linked --static --libc=musl |
apk add openjdk25 |
| Windows 11 | ✓ | ✓ | ✓ produces Program.exe |
winget install Microsoft.OpenJDK.25 |
| macOS | ✓ | ✓ | ✓ | brew install openjdk@25 |
| FreeBSD | ✓ | ✓ | ○ no GraalVM for the host — the stage is skipped, not failed | pkg install openjdk25 |
| OpenBSD | △ needs a JDK 25 build for the host | △ same | ○ no GraalVM for the host | pkg_add jdk — ports have shipped up to 21 |
Legend: ✓ supported · ○ not available on the host, and never an error · △ blocked only by JDK availability.
What actually differs per host
Every path- and process-shaped decision is read from the running JVM rather than assumed.
| Decision | Source | POSIX hosts | Windows |
|---|---|---|---|
| Classpath separator, path spelling | File.pathSeparator |
: and / |
; and \ |
| Installed launcher | installDist writes both |
bin/vsharp (#!/bin/sh) |
bin\vsharp.bat |
java binary |
os.name |
bin/java |
bin\java.exe |
| GraalVM launcher | file-name search | bin/native-image |
bin\native-image.cmd |
| Native image file name | observed after the build | Program |
Program.exe |
| Native image linking | musl loader search | --static --libc=musl on musl |
n/a |
| Executable bit | supportedFileAttributeViews |
POSIX permissions | n/a |
The POSIX launcher is Gradle's own #!/bin/sh start script; it needs no
bash, which is what makes FreeBSD and OpenBSD ordinary rather than special.
Honest status. The suite is executed end-to-end on Linux. The other hosts are
supported by construction rather than by assumption — each decision above is either
computed from the running JVM or observed from the filesystem, and each is covered by the test
suite, including the Windows-shaped native-image.cmd installation, the
.exe image name and the musl loader search. Four single-line os.name
branches and one %* in a batch file are the only code a first run on another host
would exercise for the first time.
