It looks like the build cannor find cmake. Have you installed it? If yes can you verify it is available from your path.

Humm this is a weird error. Can you list the commands you used? I will try to look into this more tomorrow.

[momenimohammad23]

yes :) first i copy again all the code in new folder then re run cmd as administrator and do this :‌

• You do not need to run as administrator
• you shouldn't work in system32, you should cd to a different folder
• did you copy the files using git clone?
• no need to run git init (it should already be a git folder after a clone)

@Cellule help me , i need a javascrip fuzzer

[Cellule]

You are ignoring a lot of errors.

1. You are creating the folder wasmfuzzer, but not actually using it.
2. After the clone, you have to go in the new folder the clone created.
3. You don't have to and should not call git init
4. Make sure every command you do doesn't output an error before you move on to the next step.

[momenimohammad23]

thank you so much ;-) i build it success ... and now i have test.* files in output directory how i can run the fuzzer ? whan i run js file in nodejs the result is -> checksum = 2C3738DE and when run js file in chrome or firefox ->

The result you have by running the javascript file is expected. This tool is not a fuzzer exactly, it simply generates random WebAssembly code using CSmith. CSmith is a tool design to produce random c code and, using emscripten, it compiles that c code into WebAssembly. The goal is mainly to find functional errors in WebAssembly engines and possibly test some edge cases.

This tool wasn't intended to produce html files however. It shouldn't be too hard to modify the command passed to emscripten to do so. You can look at https://github.com/Cellule/wasm-exprgen/blob/master/src/generate.js#L106

[momenimohammad23]

hi again after research and read your code i find a solution to generate .html with emcc when I add aditional command to your code the js , c , wasm generate success but it dosend generate html file its my change ti cli.js file

builder: function builder(_yargs) { return _yargs.options(_extends({}, commonGenOptions, { source: { required: true, string: true, describe: "Source file to regenerate" }, emargs: { string: true, describe: "Space separated extra arguments to pass to emcc", default: "-s WASM=1 -o test.html" } })); },
