ld: symbol(s) not found for architecture arm64

[amats211]

hi, trying to build in macbook pro mid2012 catalina and i get errors after i run make all.

Undefined symbols for architecture arm64:
"___muloti4", referenced from:
_reallocarray in cc-8da2a4.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [build/Pongo] Error 1

what can i do to fix?

It means you're missing libclang_rt for iOS... what toolchain are you using?

[amats211]

i am not sure if i have installed this ..
https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads

any way to check?

[Siguza]

What does clang -v print?

[amats211]

mac@Macs-MacBook-Pro bin % clang -v
Apple clang version 12.0.0 (clang-1200.0.32.29)

Hi everyone, just updating this as i still experience the issue.. Error only occurs on iOS15 branch, on main branch my mac can make with no errors.

So this should be the correct output from clang -v and not the one i posted above hehe
