[En-Nut-Discussion] Lua without floting point support

[Andre Riesberg]

Hello all,


I try to use Lua in my application. I don't need any floating point 
support.
In the Nut Configurator the checkbox "C runtime (target specifed) -> 
File Streams -> Floting point" is not set.
Under "Lua Support -> Standard Librarys -> Floating Point Numbers" the 
checkbox disabled and not checked.

If I compile my application I get a lot of error messages likes this:

...nutinstall\libnutlua.a(lmathlib.o): In function 'math_tanh':
...undefined reference to 'tanh'

I see here all the floating point functions like sin, cos, tan, floor, 
ceil....

If I add -lm to my LIBS in the makefile the compiling is successful and 
the application works fine. But the application look quit big, so I 
think there is a lot of (dead) floating point code inside.

Whats the way to disable floting point completely?

I use Nut/OS 4.9, target is a EIR compatible board.


Thanks
André
