Steps to reproduce:
Tried to build using a script which worked on the same version when I used patched rustc-1.51.0 earlier this week. Standard 'blfs' instructions as at https://www.linuxfromscratch.org/blfs/view/svn/xsoft/seamonkey.html
Note: we prefer gcc and g++, but that is irrelevant to this rust problem.
Compiling log v0.4.1
error: Cannot set
RUSTC_BOOTSTRAP=1 from build script of
note: Crates cannot set
RUSTC_BOOTSTRAP themselves, as doing so would subvert the stability guarantees of Rust for your project.
help: If you're sure you want to do this in your project, set the environment variable
RUSTC_BOOTSTRAP=encoding_rs before running cargo instead.
Second build with 'export RUSTC_BOOTSTRAP=encoding_rs' got further, but similar failure re packed_simd v0.3.4.
Success with 'export RUSTC_BOOTSTRAP=encoding_rs,packed_simd'
I hoped the build would not need any changes, but I'm not surprised.
For the moment I'm content to use those exports, but I guess the code ought to be changed in some way and I'm afraid I have no idea how.
Hope the 'Production' choice for 'Version' is correct.
