please check if indentation is correct
if use https://github.com/hugo-dc/wrc20-rust/blob/master/chisel.yml，show:

but wasm still include evn ,not ethereum
include "ewasm.h"
typedef unsigned char BYTE; // 8-bit byte
void main()
{
char hello[] = "hello world!";
BYTE buf[32];
memcpy(buf,hello,sizeof(hello));
finish((i32ptr*)buf,32);
}
See https://www.jianshu.com/p/5061caad3b7b for details.
Though I’m not sure where
ewasm.h comes from and what function name it generates.
Does someone have benchmark with SIMD to submit to this thread: WebAssembly/simd#81.
int64x2 SIMD are currently planned to be removed if nothing justifies their inclusion.
@oracle3 also, you can take a look at this repository, which is using a more recent version of the ewasm-rust-api: https://github.com/ewasm/ewasm-precompiles
@hugo-dc https://github.com/hugo-dc/wrc20-rust，This contract is published on the chain and can not pass Sentinel contract detection. How to debug and modify it? Is there any specific method?

How to solve this kind of mistake?
@oracle3 maybe you would like to take a look at
scout, https://github.com/ewasm/scout/ if you want to continue experimenting with ewasm.
@axic I use https://github.com/ewasm/sentinel-rs compiled and processed contracts to replace go-ethereum sentry contracts. Why is it always unsuccessful to publish contract transactions? There are no error hints. Trading is always pending
At present, ewasm in ethereum has the following problems:
- Sentinel contract increases the difficulty of debugging. All kinds of errors are in wast format, so we can't see what the problem is.
- Hera gives all kinds of inexplicable errors, but also can not understand them.
- Sentinel contract is written by rust and contract is written by rust. Why not give a debugging environment under rust to facilitate development?
Who can solve these problems?
@hugo-dc Your project https://github.com/hugo-dc/wrc20-rust can run in geth+Wagon environment, but it can't run in geth+hera environment. Sentinel contracts are the same. It looks like a virtual machine problem.
Why would the Sentinel contract fail ? 387390 gas ist still transactable right?
Yes... I am trying to run hash function in ewasm contract :P
Or is the
sha256 precompile stil there if I call to it (ewasm testnet)?
Is the CALL EEI function missing the output data pointers?
i.e. I see input data (dataOffset/dataLength) but nou output data ptr & len?
returnDataCopy
returnDataSize
Is private network only used at present?
However to connect a node follow these:
https://github.com/ewasm/testnet/blob/master/README.md#running-a-testnet-node-locally
https://github.com/ewasm/testnet/blob/master/README.md#running-a-testnet-node-locally
If you just want to transact you can use these:
