What's Changed

• Add wasm32-wasi-musl target by @rockwotj in #165

Incompatible changes

Zig cache path in MacOS is now in /var/tmp/zig-cache instead of /tmp/zig-cache, Windows has changed the default path too. Update your project's .bazelrc to make it work for all platforms:

common --enable_platform_specific_config
build:linux --sandbox_add_mount_pair=/tmp
build:macos --sandbox_add_mount_pair=/var/tmp
build:windows --sandbox_add_mount_pair=C:\Temp

v3.0.0

Word of caution

This release is affected by ziglang/zig#19026 ,which is a pretty serious bug. Avoid using this release until we release 3.0.1.

What's Changed

• Bump zig to 0.12.0-dev.2631+3069669bc, ask users to collaborate by @motiejus-wix in #155
• CI and MacOS fixes by @motiejus in #156
• MacOS default cache dir: /tmp -> /var/tmp by @motiejus in #163

Incompatible changes

Zig cache path in MacOS is now in /var/tmp/zig-cache instead of /tmp/zig-cache. Thus update your project's .bazelrc to make it work for both Linux and MacOS:

build --sandbox_add_mount_pair=/tmp
build --sandbox_add_mount_pair=/var/tmp

Windows

Cache path moved to C:\Temp\zig-cache. Update your .bazelrc to:

build --sandbox_add_mount_pair=C:\Temp

v2.2.0

What's New

• zig sdk: bump to 0.12.0-dev.2127+fcc0c5ddc in #140 and #141

Zig upgrade brings in the following changes:

• bump glibc support from 2.34 to 2.38
• fix integration with some glibc symbols: ziglang/zig#17702
• mitigat error: AccessDenied, which, according to Noah Santschi-Cooney, also mitigates/fixes the dreaded error: FileNotFound which we sometimes see when setting up Bazel worksace. Relevant commit in Zig: ziglang/zig@6b27096
• linker: support --(no-)undefined-version: ziglang/zig#18486. This will unbreak some Rust users.
• LLVM16 -> LLVM17, which now defaults to -Wl,--undefined-version, which can result in failure to link some C code (but easy to mitigate). Example in zlib and the specific workaround.

v2.1.3

Highlights

Upgrading is highly recommended for MacOS, as #125 solves many issues due to lack of hermeticity when compiling the zig launcher.

What's Changed

• Strip the zig-builder binary for reproducibility by @dzbarsky in #124
• zig-wrapper: compile with explicit -target by @motiejus-wix in #125

New Contributors

• @dzbarsky made their first contribution in #124
• @motiejus-wix made their first contribution in #125
