Ah yes, I missed that step. You need to patch the toolchain.

See the CI
https://github.com/tagion/ldc/blob/828926064c52eba905d9bbbf9d4d57f64a2cd267/.azure-pipelines/posix.yml#L159

Essentially replace `Wasm` with `Linux` in $WASI_SDK_PREFIX/share/cmake/wasi-sdk.cmake

Thanks!! Now it runs.

Build script can be found here.

Dear Sebastiaan, I tried the steps you provided. I did it on both my ubuntu 16.04 and Win10. I am receiving the same error on both. I used WASI-SDK 11 for windows because it is the lowest version supporting windows. And please note that the latest WASI-SDK 12 raises some cmake errors that I cannot remember as of writing this.

This one is from Win10
ldc-build-runtime --ninja "--dFlags=-mtriple=wasm32-wasi" --ldcSrcDir=../ CMAKE_TOOLCHAIN_FILE="%WASI_SDK_PREFIX%/share/cmake/wasi-sdk.cmake" WASI_SDK_PREFIX=%WASI_SDK_PREFIX% BUILD_SHARED_LIBS=OFF

output:

I reported my issues here as you said in your e-mail.

Thanks.

Looks like you're using LDC v1.24 to compile that older patched druntime - that won't work, compiler and druntime are tightly coupled. So you'll either need the LDC of that time, or rebase Sebastiaan's changes on top of https://github.com/ldc-developers/druntime/tree/ldc-v1.24.0.

Oh, I see. Thank you. I will take that into account.

Atleast so far I could compile it on Windows using:

ldc2-1.20
wasi-sdk-11.0
>> Essentially replace `Wasm` with `Linux` in $WASI_SDK_PREFIX/share/cmake/wasi-sdk.cmake

But I have to add `version (WebAssembly){}else:` at the beginnings of the files related with cpp: core/stdcpp/ exception.d, /new_d, /string_view.d, /typeinfo.d.

I cannot compile a test program on Windows using Sebastiaan's druntime. Do I need to compile the ldc from scratch? I am using a precompiled one. Why do I get `cannot find source code for runtime library file 'object.d'`? ldc2.conf has already the required include paths?

TLDR: Failed to invoke the compiler ldc2 to determine the build platform: binary

import std.stdio;

void main() {
    import core.stdc.stdio;
    printf("exit");
}

dub.json includes:
"buildRequirements": ["allowWarnings"],
"dflags": ["-mtriple=wasm32-unknown-unknown-wasm"]

etc/ldc2.conf includes

"^wasm(32|64)-":
{
    switches = [
        "-defaultlib=c,druntime-ldc,phobos2-ldc",
        "-link-internally",
    ];
    post-switches = [
     "-ID:/dlang/ldc/runtime/druntime/src>",
     "-ID:/dlang/ldc/runtime/phobos>",
    ],
    lib-dirs = ["D:/dlang/ldc/runtime/ldc-build-runtime.tmp/lib>","D:/dlang/wasi-sdk-11.0/share/wasi-sysroot/lib/wasm32-wasi/>"];
};

set PATH=%PATH%;D:\dlang\ldc2-1.20.0-windows-multilib\bin
dub --arch=wasm32-unknown-unknown-wasm --build-mode=allAtOnce --compiler=ldc2

and the output is

Your ldc2.conf is wrong, get rid of the trailing `>` in the import and lib paths. You also don't need -mtriple in dub.json; that's added by dub with the `--arch` option.

Yes, that was the problem. I didn't even know such a file exists.

Thank you again.

Just for records, in my case, I could compile the test code with some workarounds due to missing symbols although I switched back to wasm-sdk-8.

extern(C) void proc_exit(int exitcode){
    import core.stdc.stdlib;
    exit(exitcode);
}

extern(C) int clock_res_get(uint32_t id, uint64_t* resolution){
    return __wasi_clock_res_get(id, resolution);
}
