Build errors, probably around emsdk

[julianna-ciq]

I was looking to build the docs to fix an issue I raised, but I'm struggling to even build Perspective.

I'm on Windows 10, and I'm running all of my commands from Bash. I've installed CMake, Boost, and wasm-pack (+ rustup). I successfully installed all of the dependencies with npm install. I ran npm run setup and selected "Javascript" (so my .perspectiverc file says PSP_PROJECT=js).

That said, when I ran install, I did get this message:

> postinstall
> node scripts/install_emsdk.js
'.' is not recognized as an internal or external command, operable program or batch file.

(I've confirmed that the error is thrown from this line.)

...which is probably related to the fact that when I go run npm run build, I get this:

$ npm run build

> build
> node scripts/build.js

-- Running build for @finos/perspective-cpp,@finos/perspective-esbuild-plugin

> @finos/perspective-cpp@1.9.4 build
> node ../../scripts/run_emsdk.js node ./build.js

The system cannot find the path specified.
Command failed: cd C:\Users\Julianna\p2.emsdk && . ./emsdk_env.sh >/dev/null 2>&1 && cd C:\Users\Julianna\p2\cpp\perspective && node ./build.js
npm ERR! Lifecycle script build failed with error:

npm ERR! in workspace: @finos/perspective-cpp@1.9.4
npm ERR! at location: C:\Users\Julianna\p2\cpp\perspective

Command failed: npm --workspace @finos/perspective-cpp run build

Any advice on how to get unstuck from this?

You can install and source emsdk by hand, and pass PSP_SKIP_EMSDK_INSTALL=true in your environment, so that it doesnt execute this file.

The issue is the . ./emsdk_env.sh because the windows command lines (idk which you are using) do not support . as a way to source files it seems.

I installed and built emsdk, which included adding emsdk to my PATH environment variable.

My .perspectiverc file looks like:

PSP_PROJECT=js
PSP_SKIP_EMSDK_INSTALL=true

At this point, I was able to successfully run yarn install.

I re-ran yarn build in git bash, and wound up with this error:

$ yarn build
yarn run v1.22.1
$ node scripts/build.js

This feels like a related error, but I'm not sure how to get around it without changing the build scripts.

The problem is in run_emsdk.js. Are you running this (and is this repo's files) directly in your home directory? It is looking for ~\cpp\perspective which seems... unlikely to exist. It probably exists closer to ~\perspective\cpp\perspective.

So you probably need to run it in the correct directory, or even have your files in the correct directory.

The installation process should be something like:

git clone https://github.com/finos/perspective
cd perspective
yarn
# Do this echo in lieu of `yarn setup`
echo 'PSP_PROJECT=js\nPSP_SKIP_EMSDK_INSTALL=true\n` > .perspectiverc
yarn build

Although you gotta have a .emsdk directory in the perspective repo, cause it will look for it.

Sorry, I was just trying to cut out unnecessary parts of my file path, but I forgot that ~ meant something in other OS's.

I tried to restart from a clean slate. I ran these steps:

git clone https://github.com/finos/perspective
cd perspective
yarn set version 1.22.1
yarn
echo 'PSP_PROJECT=js\nPSP_SKIP_EMSDK_INSTALL=true\n' > .perspectiverc
yarn build

(my default yarn version is 3.4.2, which has its own set of issues, so I reset it to yarn's 1.x line)

After running that, I have the same error message:

$ yarn build
yarn run v1.22.1
$ node scripts/build.js

> @finos/perspective-cpp@2.0.0 build

You should run each command in

cd C:\Users\Julianna\perspective.emsdk && . ./emsdk_env.sh >/dev/null 2>&1 && cd C:\Users\Julianna\perspective\cpp\perspective && node ./build.js

And figure which one is failing exactly. If you havent installed the emsdk, and there is no .emsdk directory, you need to install it.
