  Target Milestone: ---

hey there, 

I really hope I'm not misstaken here - tried to cross compile spidermonkey-91
from an amd64 host to an armv7a target to me it seems that there is possibly a
bug somehwere in libstdc++-v3?

This could be a binutils issue.

Can you add -v to the command line and provide the output?

thank you for your answer, I'm uncertain as the error is from linking but
points to gcc-12 headers?

But I'm not close to being an expert here.

Right and I am still thinking there is a linker issue.

Can you remove -Wl,--as-needed option from the command line and try again?

The other one to try to remove is -Wl,-Bsymbolic-functions .

As expected.
I still suspect a binutils issue.

Is there a way to go back to 2.33.x?

well, my systems toolchain is gcc-12.1.0, glibc-2.34-r13 and
binutils-2.37_p1-r2 - on gentoo, binutils is slotted so I can downgrade rather
easily.

but I guess you would like me to try another binutils to bootstrap the
cross-compiler toolchain, right? removing the cross-compiler-toolchain and
rebootstraping the whole cross-compiler is in fact very easy and I'm happy to
try any sensible combination.

available binutils for cross are: 2.32-r2, 2.33.1-r1, 2.34-r2, 2.35.2,
2.36.1-r2, 2.37_p1-r2, 2.38-r2

or did you in fact ask me to downgrade glibc, from 2.34 to 2.33?
