[friebi]

Version

24.1.0

Platform

Linux 5.4.0-214-generic #234-Ubuntu SMP Fri Mar 14 23:50:27 UTC 2025 x86_64 x86_64 x86_64 GNU/Linux

Subsystem

No response

What steps will reproduce the bug?

Clone my fork of unofficial-builds and run bin/local_build.sh -r armv6l -v v24.1.0

How often does it reproduce? Is there a required condition?

always.

What is the expected behavior? Why is that the expected behavior?

It compiles :-)

What do you see instead?

Compile error

Additional information

Would be great if you could take a look!
I already revived Node 22 and 23 compilation for armv6l with PR nodejs/unofficial-builds#170. Please don't let armv6l die ❤

[bnoordhuis]

Looks like a compiler error. You're using gcc, right? Does it work with clang?

[friebi]

The unofficial-builds repo clones rpi-newer-crosstools for cross compilers for armv6l. This repo only contains GCC versions, 12.3.0 being the newest. Hence, I can't test with clang easily unfortunately.

You can try this patch: 02f8cdb#diff-c656e704eb7d989de22fd77e5fc87b80ada25baa48c8664c142521982c708305

Thanks @targos for the suggestion 👍 Unfortunately the build error now is

And I'm not so deep into template programming nor the codebase that I would have a clue about the error message 😅

[RobLeighton67]

Can confirm this happens on 24.1.0
I'm trying to build for the first time so might try 24.0.0 after I have confirmed 22.15.0 builds.

[RobLeighton67]

So 22.15.0 builds fine, but same error on 24.0.0 so not introduced in 24.1.0

[friebi]

Sorry for late reply. Yes, 22.x.x and 23.x.x build fine, 24.x.x all have the same error.

[bnoordhuis]

V8 (and therefore node) has become quite a bit more stringent when it comes to the compiler, standard library, etc. If switching/upgrading compilers is not an option, you may simply be out of luck.

[jaanrebane]

You can try this patch: 02f8cdb#diff-c656e704eb7d989de22fd77e5fc87b80ada25baa48c8664c142521982c708305

This patch helped me to compile Node.js 24 on Debian 13 x86 natively. I'm using a Thinkpad X60 with 32-bit x86 CPU. Since Node 20, I modify the source to fix 2 other issues which are not relevant here (issues #33019, #44822).

I initially had the same error as this user reports (related to int64-lowering-reducer.h), although I'm not on the arm architecture now. I'm on Debian 13 i386 (up-to-date Trixie with Bookworm kernel as of October 2025), I still thought it's worth mentioning.

[jpalus]

I've had the same issue on armv7 when switching to new LTS version. Looking at int64-lowering-reducer.h upstream commit history I've noticed this patch which is not yet in nodejs 24.11.0:

[turboshaft] Rename TupleOp to MakeTupleOp to avoid name conflicts

Cherry picking it, with minor tweaks, fixed build for me.

Regarding OP's issue on armv6 note there is another problem due to introduction of segmented tables which, performance wise, rely heavily on native 64-bit atomics which armv6 does not provide and without any modifications build simply fails on
