unikraft/lib-wamr

Unikraft port of WAMR, Intel's WebAssembly Micro Runtime

wamr for Unikraft

This is the port of wamr for Unikraft as external library. If given the --repl parameter this port will run REPL mode. Alternatively you can run a program from a file if passed as a initrd parameter. For example, if using KVM/QEMU:

• REPL: add -append "--repl" to the command line
• initrd: add -initrd <filename.wasm> to the command line

If you don't want or need your application to provide a main, you can check the "Provide main function" option in the wamr menu and this library will provide one for you.

Please refer to the README.md as well as the documentation in the doc/ subdirectory of the main unikraft repository.

lib-wamr's Issues

Buiding Error in `wasm_interp.h`

While building this I got the following error.

In function ‘wasm_interp_interp_frame_size’:
/libwamr/origin/wasm-micro-runtime-bc762fe9e2cf2d26a0cde42931c4b6ed79860047/core/iwasm/runtime/vmcore-wasm/wasm_interp.h:68:30 error: expected expression before ‘WASMInterpFrame’
   68 |   return align_uint(offsetof(WASMInterpFrame, lp) + all_cell_num * 5, 4);
      |                              ^~~~~~~~~~~~~~~

Furthermore, this error occurs after applying the changes from #2.

magic header not detected

Default interpreter assignment not working. When i start QEMU with "-initrd" the failure "magic header not detected" appears.

Command line: qemu-system-x86_64 -kernel build/app-wamr_qemu-x86_64 -serial mon:stdio -append 'console=ttyS0' -initrd hello.wasm
Unikraft version: Atlas 0.13.0~de40bcc1

How to fix this? Many thanks in advance

Error on `PTHREAD_MUTEX_RECURSIVE_NP`, not defined

Building the library currently warrants an error about PTHREAD_MUTEX_RECURSIVE_NP, aside from the other errors mentioned in #4 and #3 .

Porting this library to use the unikraft musl library

Currently, this library uses the LIBNEWLIBC and LIBPTHREAD_EMBEDDED, but it could run using the new unikraft musl library
