Issues installing rustup with OpenIndiana / Illumos

[gregbuchholz]

When trying to install rustup on new install of OpenIndiana Hipster 21.04 in a virtualbox VM, I browsed over to https://rustup.rs and got the following message:

I don't recognize your platform.

rustup runs on Windows, Linux, macOS, FreeBSD, NetBSD, and illumos. If you are on one of these platforms and are seeing this then please report an issue, along with the following values:
navigator.platform:
SunOS i86pc
navigator.appVersion:
5.0 (X11)

...but there was then a note with instructions to run:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

...that didn't make it very far. Apparently the default bourne shell doesn't like that. Bash seemed to fare better, but dies when executing the rust-init executable that it downloads from:

https://static.rust-lang.org/rustup/dist/x86_64-unknown-illumos/rustup-init

...with an error message:

ld.so.1: rustup-init: fatal: libgcc_s.so.1: open failed: No such file or directory

...but there are many versions of libgcc_s.so.1 installed:

$ find . -name "libgcc_s.so.1" 2>/dev/null
./usr/sfw/lib/amd64/libgcc_s.so.1
./usr/sfw/lib/libgcc_s.so.1
./usr/gcc/7/lib/amd64/libgcc_s.so.1
./usr/gcc/7/lib/libgcc_s.so.1
./usr/gcc/3.4/lib/libgcc_s.so.1
./usr/gcc/3.4/lib/amd64/libgcc_s.so.1
./usr/gcc/10/lib/amd64/libgcc_s.so.1
./usr/gcc/10/lib/libgcc_s.so.1

for reference on this machine:

$ uname -a
SunOS oi 5.11 illumos-fa4a3e77ed i86pc i386 i86pc

I then installed rust v 1.44 from the pkg tool, and downloaded the rustup repository. Trying "cargo test" in the rustup project results in the following:

...

I know that this works on OI; no rust package installed from OI pkg repository

snipped from a Makefile:

    export RUSTUP_HOME=$(RUSTUP_HOME); \
    export CARGO_HOME=$(CARGO_HOME); \
    export RUSTUP_INIT_SKIP_PATH_CHECK=yes; \
    curl https://sh.rustup.rs -sSf | bash -s -- -y; \
    source $(CARGO_HOME)/env; \

Hey folks, this isn't an issue with rustup-init. /usr/lib/libgcc_s.so.1 is only provided by pkg:/system/library/gcc-4-runtime (you can verify this using pkg search /usr/lib/libgcc_s.so.1). You either need to create a link from gcc-10's version (/usr/gcc/10/lib/libgcc_s.so.1), install gcc-4-runtime, or alter your ld search path using crle.
