I am wondering whether we shouldn't add libz to all cross-compiled builds for all platforms by default, now that we know that that the LLVM option is enabled by default?

This will increase the likelihood that cross-compiling rustc will work on any platform.

Do we know platforms that do not ship libz? windows perhaps?

@nielx LLVM_ENABLE_ZLIB=ON enables detection of zlib during LLVM build but doesn't force it. That means zlib will be only used if found.

Looking at CI logs in case of Windows this works like that:

windows-gnu - zlib is found on the CI so it gets enabled, LLVM on this platform is linked statically so zlib is linked statically as well
windows-msvc - zlib is not found on the CI it gets disabled

The issue remains that this will in principle break any cross compiling rustc for any platform that has libz on it. I see five options:

Set LLVM_ENABLE_ZLIB=OFF for cross-compiled targets. The upside is that it will not break anything for anyone, the downside is that there is no support for compressed sections in elf libraries (though if I understand correctly, this is only for the llvm tools that we distribute and not the rustc compiler itself?)
Keep LLVM_ENABLE_ZLIB=ON and link cross-compiled rustc to libz.so by default, and add a mechanism to opt out manually. The upside is that it is likely that on many platforms cross-compiling rustc will work out of the box. The downside is that for some platforms it creates more work to opt out of linking to libz.
Keep LLVM_ENABLE_ZLIB=ON and have a list of cross-compiled targets that link to libz.so. This is the approach of this patch.
Combination of 1 and 3, where for cross-compiling LLVM_ENABLE_ZLIB=OFF by default, except for platforms that opt in.
Devise a test in build.rs to determine whether or not the target's LLVM links to libz.so.

Personally, while I cannot quantify it definitively, solution 2 sounds like it will get most targets right without any additional manual work/patches, so that's where my preference would be. If we want to be on the safe side, we could go for option 5. Unfortunately I do not seem to be able to find the CI logs, do do some investigation, but that's where I would go next.

Mark-Simulacrum · 2020-08-24T15:40:46Z

I agree that option 2 seems like the best way, and we should surface the option in config.toml (probably in a target-specific section).

That said, I'm going to r+ this since it does seem like a net-improvement to me for the time being.

On native builds `llvm-config` picks up `zlib` and this gets pased into the rust build tools, but on cross builds `llvm-config` is explicitly ignored as it contains information for the host system and cannot be trusted to be accurate for the target system. Both DragonFly and Solaris contain `zlib` in the base system, so this is both a safe assumption and required for a successful cross build unless `zlib` support is disabled in LLVM. This is more or less in the same vein as rust-lang#75713 and rust-lang#75655.
