[sylvestre]

install bolt-15 fixes your problem?

[lerno]

It resolves that particular error, but in the linking step it now ends up with:

/usr/lib/x86_64-linux-gnu/libtinfo.so  /usr/lib/llvm-15/lib/libLLVMDemangle.a && :
/usr/bin/ld: /usr/lib/llvm-15/lib/libLLVMAArch64AsmParser.a: error adding symbols: archive has no index; run ranlib to add one
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Probably #58316 is related.

[sylvestre]

yeah, they are duped

About the ar issue, it is a different issue (i enabled LTO)
