Tools not working

[winksaville]

I tried to use npm install webassembly and wa compile failed to compile. I then forked and cloned this repo and tried it and it takes the same way. After investigating I determined the pre-compiled tools isn't untaring properly and in linux-x64 only clang is there and it's not executable.

I then tired untaring manually and that worked but when I tried to execute clang it failed because of missing shared libraries. In the end I used a local version of wasm clang, binaryen, want tools that I'd created previously. And symlinked tools/bin/linux-x64 to my build, and that worked.

Hmm, that's strange. The tool used to create the tgz is https://github.com/archiverjs/node-archiver - not sure if that's an issue on their side.

However, a Linux install is performed on TravisCI, and it seems to be working there. The test cases are rather rudimentary, though - just calling the tools and watching for error codes.

Might also be that the binaries are tied to Debian-flavoured distributions somehow because that's what I used.

I'd suggest you trying it, I was surprised that the dynamic libs were missing when I did it manually. Probably something I've done wrong and glad to help debug it, but won't be back online for several hours as I'm traveling right now.

I'm on OS X, and the tools fail to untar properly for me also. From a fresh install, I end up with a tools directory that looks like:

$ tree node_modules/webassembly/tools
node_modules/webassembly/tools
└── bin
    ├── LICENSE-BINARYEN
    ├── LICENSE-LLVM
    ├── README.md
    └── darwin-x64
        └── clang

2 directories, 4 files

and clang is corrupted.

Manually downloading the archive on the releases page and extracting into the proper location works though.

[dcodeIO]

I repacked and reuploaded the darwin archive now. Hope that helps. If it doesn't, then there's probably something wrong with the unpacker we use.

[bharley]

No dice. I was able to use the previous archive successfully by doing the extraction myself, so I didn't figure that would change anything.

[dcodeIO]

My assumption here is that the archive was fine for any other unpacker, but incompatible with the node based unpacker we use internally for some reason. Could you try if it is working now? If that doesn't solve the issue, which is likely, I'd at least know where to look at next.

[bharley]

It didn't work. I dug into the install script, and it looks like tar.gz isn't preventing the node process from exiting. If I run all of the functions through the Node repl, it works perfectly.

It looks like there are a couple of relevant bug reports on tar.gz's Github: alanhoff/node-tar.gz#29 and alanhoff/node-tar.gz#44

same here command not found by going to node_modules/webassembly/bin and typing : ./wa compile -o program.wasm program.c i can compile
