You might find the basis of an approach in the first half of this script runs an x86_64 Ada-capable compiler (on an M1 Mac; not sure this is necessary) to build an x86_64 cross compiler to aarch64 (Apple silicon), which might be all you need; the second part uses that to build a native aarch64 compiler, which you wouldn’t need unless you want to compile on the target.
Of course, there’s a whole load of mac-isms in there!
Macs (x86_64, aarch64) are very very similar; you’ll probably need to have a copy of the target libraries on the host system; the last time I did this was in 2005 or so, linux / vxworks 5.3
In all cases, building a cross-compiler is best if you have a host compiler built from the same sources.

0 [main] bash (2588) C:\Users\ethin\.cache\alire\msys64\usr\bin\bash.exe: *** fatal error - cygheap base mismatch detected - 0x1289408/0x11D9408. The fact that errors like this still happen is just ridiculous IMO.
I've published the initial release of an installer for alire: https://github.com/AJ-Ianozi/getada
I try to be clear in the readme, and I put some more details here: https://www.reddit.com/r/ada/comments/yzx6hz/getada_an_unofficial_installer_for_alire/

Sorry but i had to test GPT for spark programming language:
Can you write "hello world" in spark programming language?
Yes, here is how you can write "Hello World" in Spark:
import org.apache.spark.SparkContext
import org.apache.spark.SparkContext._
import org.apache.spark.SparkConf
object HelloWorld {
def main(args: Array[String]) {
val conf = new SparkConf().setAppName("Hello World")
val sc = new SparkContext(conf)
val rdd = sc.parallelize(List("Hello World"))
rdd.foreach(println)
}
}
In this example, we first import the necessary classes from the Spark API. Then, we create a SparkConf object that contains the configuration for our Spark application. Next, we create a SparkContext object using the SparkConf object. This is the main entry point for Spark functionality.
Next, we create an RDD (Resilient Distributed Dataset) containing the string "Hello World". An RDD is the main data structure in Spark and is a distributed collection of elements. In this case, we create an RDD from a List containing the string "Hello World".
Finally, we use the foreach method to print each element of the RDD to the console. When run, this program will print "Hello World" to the console.

but a competition in my school requires me to make an android app
is there something for that in Ada, its not somethign ada is made to do, but its possible in C and zig. It would probably be an amazing experience to build an android app in ada

I just read AdaCore's recently released "Introduction to Embedded Systems Programming" by Patrick Rogers. It's an excellent source of information on not only how to approach embedded systems development, but covers some of the more advanced, rarely discussed areas of the language. I was delighted when it directly addressed an issue I've been grappling with. While Ada encourages high-level abstractions when specifying a model, such as representing a device's status flags as boolean fields in a record, or defining a bank of registers as an indexable array of 32-bit unsigned values, it's unclear how they're implemented at the low level. Specifically, will the compiler wastefully generate a sequence of load and store instructions when setting several status flags in a record to true, or will it efficiently reduce those assignments into a bit mask and set them in single operation? The guide goes into depth how aspects such as atomic, volatile and full_access can specify the intent at the machine level. Coming from other languages such as C/C++, the ability to write code at an abstract level, instead of dumbing it down for the sake of the compiler has been an incredible revelation. The guide is a must read for not just embedded Ada development, but for all Ada development!
This is such a great read. Thanks for sharing this.
I tried the following:
I cloned the repository, and created a library project in-place with alr in the repo directory. Then I selected gnat-arm-elf toolchain.
Then I issued this:
alr exec – ./scripts/install_dependencies.pyThe process stops with the following error:
ROOT_DIR :/home/ptihanyi/adawsp/Ada_Drivers_Library
/home/ptihanyi/adawsp/Ada_Drivers_Library/bb-runtimes already cloned
