Installation

On local env's terminal(e.g. windows):

$ git clone https://github.com/Cartman0/vsc-c-em-wabt-meson.git
$ cd vsc-c-em-wabt-meson
$ code .

1. Click "Remote Container" on LeftBottom in VSCode.
2. "Reopen in Container" or "Open Folder in Container"

Example: How to switch compiler and linker on Meson to clang and lld(ld.lld)

graph BT
    subgraph "--native-file native_clang.ini"
        c["c: clang"]
        cld["c_ld: lld(ld.lld)"]
        subgraph "default native"
            c_d["c: gcc"]
            cld_d["c_ld: ld"]
        end
        c_d -..-> c
        cld_d -..-> cld
    end

Loading

create native_clang.ini:

[binaries]
c='clang'
c_ld='lld'
cpp='clang++'
cpp_ld='lld'

meson setup <build dir> <source dir> --native-file native_clang.ini on termial:

$ meson setup build_c/build build_c --native-file build_c/native_clang.ini

result:

meson have been able to switched to clang and lld as bellow:

C compiler for the host machine: clang (clang 15.0.0 "clang version 15.0.0 (https://github.com/llvm/llvm-project fbce4a78035c32792b0a13cf1f169048b822c06b)")
C linker for the host machine: clang ld.lld 11.0.1
