source-built aspnetcore fails during rollup on ppc64le

[tmds]

The build is failing as follows:

    > build:debug
    > rollup -c --environment development --forceExit
    
    /home/tester/dotnet/src/aspnetcore/node_modules/rollup/dist/native.js:38
    	throw new Error(
    	^

@javiercn any recommendation regarding this one? Is this an important step that is required to run as part of the build, or can it be skipped on this particular platform?

@mthalman, @MichaelSimons do you know if this distro is something we MUST support or not?

[javiercn]

@mkArtakMSFT this might require installing "@rollup/wasm-node" and potentially overriding rollup with an npm override.

ppc64le is community supported meaning principally community-driven contributions with best effort support from Microsoft.

Comparing rollup with System.Runtime.InteropServices.Architecture, it looks like rollup doesn't support a number of .NET architectures, including loongarch, ppc64le, s390x and x86.

Looks like there is already some community effort to get a s390x build of rollup going: https://github.com/rollup/rollup/pull/5346 ... I'll see if can help that succeed.

@Swapnali911 @janani66 there's a similar PR for ppc64le: https://github.com/rollup/rollup/pull/5350. You may want to look into that.

this might require installing "@rollup/wasm-node" and potentially overriding rollup with an npm override.

@javiercn @mkArtakMSFT does "@rollup/wasm-node" provide an alternative option that would work on both ppc64le and s390x?

@tmds will check

So any workaround for now?

[uweigand]

As of version 4.13.1, rollup now supports s390x and provides a linux-s390x prebuilt binary: https://www.npmjs.com/package/@rollup/rollup-linux-s390x-gnu

[sec]

What about other OS'es? Having rollup used in build process, makes it "hard" to port to other platforms :)

[uweigand]

As of version 4.13.1, rollup now supports s390x and provides a linux-s390x prebuilt binary: https://www.npmjs.com/package/@rollup/rollup-linux-s390x-gnu

And as of version 4.13.2, ppc64le support is also present: https://www.npmjs.com/package/@rollup/rollup-linux-powerpc64le-gnu

So I think the only missing piece would be to upgrade the required rollup version in the aspnetcore package.json file.

Still no FreeBSD in there, so maybe some option to use the wasm one would be helpfull to have also in case of fallback?

[uweigand]

And as of version 4.13.2, ppc64le support is also present.

Turns out this wasn't quite correct; ppc64le support is fixed in version 4.14.2 now.

[sec]

Are there any plans regarding this one? Previous 8.x and 9p1 build fine, but starting from 9p2 this issue is blocking native builds under FreeBSD (and probably other OS'es not supported atm by rollup) - any "easy" to fallback to @rollup/wasm-node while doing VMR build ?

[mkArtakMSFT]

We'll try to prioritize this for preview 6 release. @wtgodbe , @javiercn FYI

[mkArtakMSFT]

Closing this as a dupe of https://github.com/dotnet/aspnetcore/issues/54541 as that's the one we'll use for tracking this work.
