I am encountering an issue while running the JavaScript benchmark command for the CDF of a normal distribution.

make benchmark-javascript-files FILES="/Users/pgb/stdlib/lib/node_modules/@stdlib/stats/base/dists/normal/cdf/benchmark/benchmark.native.js"

A similar issue also occurs when running the JavaScript benchmark for the CDF of an arcsine distribution which was the reference PR for the current PR feat: add C implementation for arcsine CDF #3354

Can you please help me resolve this?

@manvith2003 What is the issue? Can you provide a screenshot? One thing is that you need to have first compiled the package's native add-on before you can run the benchmarks.

Sorry for the confusion, the command in the issues is incorrect since it uses a hard-coded path from my system. The correct command is

make benchmark-javascript-files FILES="$(pwd)/lib/node_modules/@stdlib/stats/base/dists/normal/cdf/benchmark/benchmark.native.js"

so that it uses your current working directory (via pwd). I will be looking into updating the issues with the correct command.

Updated: I (Athan) updated this comment and the suggested command to fix a typo.

After the running the new command also encountering same issue

[kgryte]

@manvith2003 That is because @Planeshifter's suggestion is still incorrect. From the root project directory,

make benchmark-javascript-files FILES="$(pwd)/lib/node_modules/@stdlib/stats/base/dists/normal/cdf/benchmark/benchmark.native.js"

I suggest studying the other suggested commands next time and seeing what is different. You likely could have deduced the above by examining the paths and seeing what is different from what you were attempting to run.

Noted, I’ll review more carefully next time. Thanks!
