I managed to make the AngelScript runtime build on armv7l architectures by adding -Wa,-mimplicit-it=thumb when an armv7l architecture is detected, per the instructions here: https://wiki.ubuntu.com/ARM/Thumb2
This modifies only the projects/gnuc/Makefile file in the AngelScript build system. The AngelScript author has also been made aware of these changes.
Theoretically this modification should not impact building NymphCast on other platforms, but it should be tested regardless.

Yup that worked, thanks! 😄

That's in an AngelScript ASM file. I wonder if it's an AngelScript ARMv7 issue?
from nymphcast.
MayaPosch
commented on August 20, 2024
Looking at as_callfunc_arm_gcc.S, it appears that this issue is due to it trying to compile the ASM file for the Thumb ISA when it should use the regular ARM ISA. I'll have to see whether I can replicate this issue and maybe fix it in the Makefile.

Doesn't seem to work for me, it still fails on armv7.

The Makefile checks with uname -m what the underlying system architecture is. What does the environment which you're running it in return? Since on Debian I got armv7l back, that's what I'm checking for.

PureTryOut
commented on August 20, 2024
Ah makes sense, but that isn't a reliable check. In Alpine's case, armhf and armv7 packages are actually built on a 32-bit capable aarch64 system. uname -m thus reports armv8l and the build system doesn't realize it's incorrect.

I have removed the use of uname. Instead the Makefile uses the -dumpmachine flag of GCC to determine the target architecture.

Still no luck sadly, not sure what's up... https://gitlab.alpinelinux.org/PureTryOut/aports/-/jobs/90618

I'm not sure what kind of GCC toolchain is used there. It should target arm-linux-gnu, no?
The Makefile just checks for a string that starts with arm-, so that covers a lot of territory.

Just the usual.
On my local (x86_64) machine gcc -dumpmachine gives me
▶ gcc -dumpmachine
x86_64-alpine-linux-musl
I'm guessing that should be armv7l-alpine-linux-musl on armv7?

MayaPosch
commented on August 20, 2024
It should start with arm- since the toolchain targets ARMv7. ARMv8 (64-bit) uses aarch64-.

I have changed the Makefile to output the GCC triplet, so we can more easily see what gcc -dumpmachine actually returns :)

Huh, that's an odd one. Only seen similar triplets with clang so far.
I have added the armv7- option as well to the Makefile. It better work now :)
