piCore-14.x x extensions updated

[Juanito]

The piCore-14.x x extensions have been updated - it would be best to update all of them at the same time.

Hi

I'm trying to compile firefox

Code: [Select]

$ time ./mach configure

 1:08.78 checking for rustc... /usr/local/bin/rustc

 1:11.35 ERROR: The rust compiler host (armv7-unknown-linux-gnueabihf) is not suitable for the configure host (armv7l-unknown-linux-gnueabihf/arm-unknown-linux-gnueabihf).
 1:11.35
 1:11.35 You can solve this by:
 1:11.35 * Set your configure host to match the rust compiler host by editing your
 1:11.35 mozconfig and adding "ac_add_options --host=armv7-unknown-linux-gnueabihf".
 1:11.35 * Or, install the rust toolchain for armv7l-unknown-linux-gnueabihf/arm-unknown-linux-gnueabihf, if supported, by running
 1:11.35 "rustup default stable-arm-unknown-linux-gnueabihf"
Does that mean I'll need to compile rust as well ?
I guess it means the compiler in the repo was built in armv7l and probably won't work in armv7 or anything lower.

[Paul_123]

Rust was just rebuilt, but yes, it was done on a pi4. When on a pi3, you need to override the host triplet.  The older pi hardware is quickly becoming software obsolete.   

Moving your pi3 to aarch64 might be easier to work with.

Grab my rpi4

Interesting, rust doesn't work for me on pi4 either

Code: [Select]

$ sudo /mnt/mmcblk0p3/V3DLib/obj/qpu-debug/bin/detectPlatform
Platform    : Raspberry Pi 4 Model B Rev 1.1
Model Number: BCM2711

Moving your pi3 to aarch64 might be easier to work with.   

I'm simply filling out the missing pieces for the 32-bit, I get requests of porting firefox-perf.tcz to 32-bit
I'm quite curious on how it will perform as well

P.S. I just send nss.tcz and nspr.tcz to tcesubmit at gmail
They are needed for newer firefox (115.1 ESR)

[Paul_123]

I recall having issues getting rust to build with the same toolchain triplet as gcc.  It had to be forced to armv7.  Most things don't care.

Does editing the mozconfig resolve the issue? 

[polikuo]

Does editing the mozconfig resolve the issue?

I've found another way to bypass the checker by editing certain files.
Specifically, build/moz.configure/rust.configure
I'll upload the detailed instructions when everything is ready.

[Paul_123]

good luck building. I failed miserably the last time I tried due to hitting the memory limit for a single process.... but then I was going the normal gcc route.  llvm might be different.

Hi

I get requests of porting firefox-perf.tcz to 32-bit

If it was only my request, I withdraw it....sorry for not saying it earlier.
My browser needs are satisfied with get-chromium-browser.tcz

Hi.

BZ2 module for python3.11 on armv7 is not available.
Google says you need to specify it when building python.
I've tried loading bzip2-dev, it has nothing to do with the error.
I can probably get around with an older version, node.js doesn't appears to depend on python anyway...

[Paul_123]

Interesting that you cannot even add to python as a separate module.  I'll have to adjust my python build scripts.

[Paul_123]

Python3.11 has been updated on all piCore repos

[polikuo]

Apparently, Node has dropped armv6 ages ago
https://github.com/nodejs/build/issues/1677
It took me 4 tries until a success build on my RPI3B.
GCC didn't work for me, evey tries it failed with different reasons.
With LLVM, I was finally able to get a success build for armv7.
Sorry, armv6 users, but I'm gonna build Firefox for armv7.
Frankly speaking, armv6 specs are not that beefy anyway.

[polikuo]

Apparently, firefox now requires webassembly
I'll need to rebuild llvm, won't I ? 
If yes, which version should I build ? (for armv7 and probably aarch64)

I would just rebuild the current version.

[polikuo]

I'm tired. 
Any suggestions ?
