wasm32-freestanding: dynamic linking unavailable on the specified target

[clebert]

Zig Version

0.12.0-dev.2586+3c7970dc4

Steps to Reproduce and Observed Behavior

zig build-lib src/foo.zig -OReleaseSmall -target wasm32-freestanding -mcpu baseline+simd128 -rdynamic -dynamic
error: dynamic linking unavailable on the specified target

Expected Behavior

The same command works in Zig 0.11 and produces a .wasm file.

This behavior was changed in #17815. When upgrading from a tagged release to a master version I recommend checking breaking changes before upgrading. Also, the language reference is worth checking as it was updated with this change also. I will, however, keep this issue open as the compile-error you received is incorrect, as building dynamic libraries is supported for this target (but not what you want in your case).

Thanks for the quick help. Now that I know what to look for, I found it in the Language Reference (https://ziglang.org/documentation/master/#Freestanding). I missed it before. I was not aware that the breaking changes for master are already documented.
