Error with create-exe #2895

cyw3 · 2022-05-21T12:46:32Z

Describe the bug

when i use create-exe

$ wasmer create-exe hello.wasm -o ./hello --enable-all
Engine: staticlib
Compiler: cranelift
Target: x86_64-unknown-linux-gnu
error: Failed to compile C source code
╰─▶ 1: C code compile failed with: stdout: 
       
       stderr: wasmer_main.c: In function ‘handle_arguments’:

          ^
       wasmer_main.c:49:3: note: use option -std=c99 or -std=gnu99 to compile your code

And after i add .arg("-std=c99") at this line and build the wasmer again:

$ wasmer create-exe hello.wasm -o ./hello

Steps to reproduce

it is a go project.

// main.go
package main

func main() {
	println("Hello World!")
}

Then use tinygo to build go file to wasm.

docker run --rm -v $(pwd):/src tinygo/tinygo:0.23.0 \
    /bin/bash -c "
    cd /src
    tinygo build -o hello.wasm -target wasi main.go
    "

use wasmer to create exe.

wasmer create-exe hello.wasm -o ./hello
./hello

I think you need to gives much more information on your system. What hardware/OS are you using, and the different compiler version too.

gcc is 4.8 !!! :O
This is a really old version of gcc. I assume the OS is old too. We'll need to find a way to reproduce the issue.

cyw3 · 2022-05-21T13:28:33Z

Can you provide a docker image to use the Wasmer's create-exe?

Thanks!

epilys · 2022-05-21T13:51:13Z

Centos with 3.10 kernel is also from 2014.

cyw3 · 2022-05-22T03:11:55Z

I use the docker to build wasmer, create-exe and run ./hello.
But have the same error.

docker run --rm -v $(pwd):/src rust:1 \
    /bin/bash -c "
    cd /src
    make build-wasmer
    "

export TARGET_DIR=/data/example/go/hello
export WASMER_DIR=~/.wasmer/
docker run --rm \
    -v $(pwd)/target/release:/wasmer/bin \
    -v ${TARGET_DIR}:/test \
    -v ${WASMER_DIR}:/root/.wasmer \
    rust:1 \
    /bin/bash -c "
        cd /test
        export WASMER_DIR=/root/.wasmer/
        /wasmer/bin/wasmer create-exe hello.wasm -o ./hello
"

docker run --rm \
    -v ${TARGET_DIR}:/test \
    rust:1 \
    /bin/bash -c "
        cd /test
        ./hello
"

And when I use the ./hello above in Centos with 3.10 kernel (the old OS I using daily), I get a new error:
```
$ ./hello
./hello: /lib64/libc.so.6: version `GLIBC_2.18' not found (required by ./hello)
```
Can I use ./hello without installing other libraries?

This issue is somewhat related to #2916

cyw3 · 2022-06-12T10:43:35Z

Today, I update the codebase and try it again. The error was gone, but I get a new error:

$ cd ./tests/examples

$ export WASMER_DIR=/workspaces/wasmer/package/

$ /workspaces/wasmer/target/release/wasmer create-exe fib.wat -o ./fib
Engine: staticlib

Target: x86_64-unknown-linux-gnu
✔ Native executable compiled successfully to `./fib`.

$ ./fib
Error getting WASI imports!
Error len: `52`

syrusakbary · 2022-06-21T16:04:33Z

create-exe only works with WASI programs for now, so since fib doesn't have a main function, it fails.

Ideally, wasmer create-exe should require the wasm modules to be WASI ones and throw an error in case they are not

We are working to re-add it in Wasmer (master) as part of #2987

I can use create-exe on windows now. All I need are to install llvm v11+ (I installed the latest v14), execute vcvarsall.bat (open visual studio Developer Command Prompt), see more details on #2977 (comment).

epilys · 2022-08-19T09:40:56Z

Closing this, I was able to create a hello world executable using master:

manos ~/wasmer % package/bin/wasmer create-exe ./tests/wasi-wast/wasi/snapshot1/hello.wasm -o hello
Compiler: cranelift
Target: aarch64-apple-darwin
Format: Symbols
Using libwasmer file: /Users/manos/wasmer/package/lib/libwasmer.a
Using path `/Users/manos/wasmer/package/lib/libwasmer.a` as libwasmer path.
✔ Native executable compiled successfully to `hello`.
manos ~/wasmer % ./hello
Hello, world!
