When I add
pragma Initialize_Scalars

To my local configuration pragmas on a light runtime.

I get

hal.ads:164:04: error: file s-scaval.ads not found
hal.ads:164:04: error: entity “System.Scalar_Values.Is_Isf” not available

The complete output follows.

Merry xmas all.

I simplified my Last Chance Handler by using

Interfaces.C.Strings.Value

The compiler output undefined reference to ‘strlen’

light-cortex-m4f/adalib/libgnat.a(i-cstrin.o)

I could go back to my manual string null termination finding function. Or should I look into Gnat. Could someone point me to the right place to report and or submit a patch (is it gerrit that GCC uses or something)?

I wonder if a light runtime attribute might be handy for Alire search?
