Re: rust 1.33.0 bootstrap fails on NetBSD/aarch64

[Rin Okuyama <rokuyama.rk%gmail.com@localhost>]

Thank you for your rapid response.

However, it does not work. I missed an error message:

----
error: couldn't load codegen backend "/build/pkgsrc/lang/rust/work.aarch64/rust-bootstrap/lib/rustlib/aarch64-unknown-netbsd/codegen-backends/librustc_codegen_llvm-llvm.so": "/build/pkgsrc/lang/rust/work.aarch64/rust-bootstrap/lib/rustlib/aarch64-unknown-netbsd/codegen-backends/librustc_codegen_llvm-llvm.so: Undefined PLT symbol \"_ZNSt15__exception_ptr13exception_ptrC1ERKS0_\" (symnum = 4197)"
----

This should be due to a recent ABI change for libstdc++:
http://cvsweb.netbsd.org/bsdweb.cgi/src/tools/gcc/Makefile#rev1.92

Actually, if libstdc++.so.8.2 from 2019-02-22 is installed into
rust-bootstrap/lib, the error disappears (with original Makefile).
However, GCC crashes instead:

----
  = note: /build/pkgsrc/lang/rust/work.aarch64/.gcc/bin/gcc: Undefined PLT symbol "_ZNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEE9_M_createERmm" (symnum = 22)
----

Thanks,
rin
