[Compile.linkLibC]: root struct of file 'c' has no member named 'SIG'

[wanton marlin]

I get this error while building my build script for target rust .{ .cpu_arch = .thumb, .cpu_model = .{ .explicit = &std.Target.arm.cpu.cortex_m4, }, .os_tag = .freestanding, .abi = .eabihf, });

I cannot find any documentation on this error.

error:

zig\lib\std\os.zig:124:23: error: root struct of file 'c' has no member named 'SIG'
zig\lib\std\c.zig:1:1: note: struct declared here```

this is an issue with exe.linkLibC()

Compile.linkLibC: root struct of file 'c' has no member named 'SIG'

linkLibC isn't supported on freestanding

the libcs shipped with the compiler only support linux/mac/win

I recently created an archive containing parts of the toolchain and then linked to it manually as a dependency
