error: could not compile euclid (lib) due to 28 previous errors

[tronical]

Could it be that you're compiling on a system without floating point arithmetic? Then you need to enable the libm feature of the Slint crate to enable the floating point arithmetic emulation.

[ogoffart]

Assuming the problem was because the libm feature of the slint crate was missing.
