x86_64-sun-solaris linking error

[jcoughlin9]

I am trying to cross-compile from x86_64-unknown-linux to x86_64-sun-solaris. I have a working C cross toolchain and I cross compiled the std crate basically following the directions from https://github.com/japaric/rust-cross.

However, when I try to cross compile a Rust program, I get a linking error listing many undefined references.

$ rustc --target=x86_64-sun-solaris -C linker=i386-pc-solaris2.10-gcc hello.rs
error: linking with `i386-pc-solaris2.10-gcc` failed: exit code: 1

error: aborting due to previous error

Is rustc supposed to automatically invoke the linker with all needed libraries, or am I just doing something wrong? It appears to be necessary to explicitly link against resolv. Adding -lresolv brings it down to only a few undefined references (__errno_location, strnlen, and posix_memalign):

Are these symbols defined in another library that needs to be linked, or is there a better way to resolve this?

I am using rustc 1.17.0, which I compiled to get the x86_64-sun-solaris std crate.

[bgermann]

The problem seems to originate from Solaris 10. Rust 1.22.0 (will be promoted to beta these days) uses memalign instead of posix_memalign, so this is fixed there. strnlen and dl_iterate_phdr are not available on Solaris 10 as well, so maybe you used another compiler with Solaris 11 or illumos sysroot to compile the stdlib? With this setting I can reproduce parts of this issue. If that is the case, it should be closed.

[sanxiyn]

By "it should be closed", do you mean Solaris 10 is unsupported by x86_64-sun-solaris target? That does not match https://forge.rust-lang.org/platform-support.html, which states "Solaris 10".

[bgermann]

No, I don't mean Solaris 10 is unsupported. But using an untouched Solaris 11 or illumos sysroot for cross compiling and then running in Solaris 10 should not be considered a supported use case because then the mentioned non-Solaris 10 symbols are picked up during compilation. For the continuous integration I made the necessary changes to an illumos sysroot to also support Solaris 10. That is what the bug reporter should also do (or just use a Solaris 10 sysroot or even better compile with the precompiled x86_64-sun-solaris libstd, which does not link to these symbols).

Basically the same as #57497 but for Solaris.
