PolkaVM/CoreVM SDK

This repository contains the source code for musl library patched for PolkaVM/CoreVM. It is built for RISCV, uses picoalloc as memory allocator, and forwards all system calls via pvm_syscall host-call.

Besides that we provide polkavm-cc and polkavm-c++ wrappers to build applications that use the musl port.

How to build the SDK

# Build the toolchain for `polkavm` or `corevm`.
# Tested with `clang-19` and `clang-20`.
env CC=clang CXX=clang++ LLD=lld ./setup.sh corevm

# Activate (setup environment variables) for the toolchain.
# Either `polkavm` or `corevm`.
. ./activate.sh corevm
