Errors when building firmware

[telec16]

I can't build the firmware with MPLAB X IDE v5.20, XC8 v1.44. I tried various versions of MPLAB and XC8 (1.36, 1.42, 2.10), and various XC8 settings (Memory model, C standard, ...).

Here is the log :

@telec16 I was able to make the "floating-point not supported" warning go away by upgrading my project from the git-provided project file version to MPLAB X v5.30 and linking against the "C90" library instead of the C99 one (XC8 Linker > Runtime).

I also changed the standard to "C90" (required to compile at all), and changed the memory model float size to 24-bits (it doesn't seem to make a difference).

Even with this change, I can't get the firmware to fit. The firmware barely fit as-is in old versions of MPLAB X. Something changed in the code generating and now the firmware size just plain doesn't fit anymore (with the free compiler and -O2) :(.
