I believe this should be TAB indentation. Ensure you have EditorConfig enabled.

kgryte · 2023-04-10T21:20:02Z

@Pranavchiku How are you running the example mentioned above? E.g., what is the command you are running?

Also, how have you tried debugging this already?

kgryte · 2023-04-10T21:23:32Z

Feel free to push up the example code and associated Makefile. Without being able to see the files, hard to debug.

kgryte · 2023-04-10T21:24:40Z

Can you also add an include entry to the package.json file?

Pranavchiku · 2023-04-11T05:15:43Z

How are you running the example mentioned above? E.g., what is the command you are running?

make examples-c EXAMPLES_FILTER=.*/blas/base/srotg/.*

Also, how have you tried debugging this already?

Everything else looks fine, I tried playing with package.json and manifest.json but was not able to resolve this.

Pranavchiku · 2023-04-11T05:18:28Z

Can you also add an include entry to the package.json file?

I am not sure. Do you mean "include": List of dependencies?

kgryte · 2023-04-11T05:23:14Z

I mean in the "directories" field, along with src, benchmark, etc.

kgryte · 2023-04-11T05:25:56Z

lib/node_modules/@stdlib/blas/base/srotg/package.json

    "doc": "./docs",
    "example": "./examples",
    "lib": "./lib",
+    "src": "./src",


Add the "include" path here.

E.g.,

stdlib/lib/node_modules/@stdlib/math/base/special/absf/package.json

Line 22 in a0a7caa

"include": "./include",

.

Still, I get the same error

kgryte · 2023-04-11T05:40:31Z

Am able to reproduce locally. Debugging now...

kgryte · 2023-04-11T05:50:31Z

Okay. I know what the problem is. Working on a fix.

kgryte · 2023-04-11T06:09:35Z

Should work now. In short, we need to update the build configurations to allow for using stdlib packages, which means supporting dependency resolution. Other BLAS packages, such as dcopy, etc, work with their current Makefiles as they don't depend at all on stdlib packages, such as absf, etc.

Pranavchiku · 2023-04-11T06:12:19Z

Okay, perfect! I will add rest of the files by today. Thank you for resolving this.

Pranavchiku · 2023-04-11T13:10:17Z

@kgryte I guess binding.gyp and include.gypi needs to be modified as well ( according to new manifest.json )

When I try to build node addons

make install-node-addons NODE_ADDONS_PATTERN=blas/base/srotg

It throws
