Dear Ada Enthusiasts,

type Long_Money_Type is delta 10.0**(-22) digits 38;

On The First Machine Ubuntu Linux 64 bit GNAT 8.3.0 this works.
On The Second Machine Alpine Linux 64 Bit GNAT 10.3.1 20211027 i get this error:

adx-lib-money.ads:14:29: scale exceeds maximum value of 18
adx-lib-money.ads:14:54: digits value out of range, maximum is 18

Is There an way to change the maximum value ?

Background: I'm working on porting an Ada project from Vxworks to a Linux platform. The project heavily relies on usage of Ada's dynamic task priorities.

I've done a couple experiments which have left me confused. Ada task priorities seem to have no effect on the underlying Linux priority/niceness. Two identical tasks with different priorities take equally long to complete, even when pinned to one CPU core.

Question: What are the semantics of Ada tasks on Linux? Why am I seeing no effect from setting task priorities?

I'm recieving the error error: No index.toml file found in index when I'm trying to use alr get gnat_native and alr get gprbuild on Debian. I made sure that Alire is installed, by using the 'alr' command I get 'alr 1.2.2' when I do the command.

I expected to download the Alire tools, and not to recieve a error when I do alr get gnat_native and `alr get gprbuild'. I made sure that Alire is installed, by using the 'alr' command I get 'alr 1.2.2' when I do the command.
