[Bug]: odin package doesn't work properly

[xigoi]

Problem description

When I install the odin package and try to compile or run a valid Odin program (such as the first example in the documentation), it produces the following error:

Syntax Error: Path does not exist:

Doing the same on a non-Android device compiles the program as expected, so this is a Termux-specific issue.

What steps will reproduce the bug?

• Install the odin package with pkg install odin
• Create an empty directory and cd to it
• Create a file hellope.odin with the following content:

  package main
  
  import "core:fmt"
  
  main :: proc() {
  	fmt.println("Hellope!")
  }
  

• Run the command odin run .

What is the expected behavior?

The command should compile the program and output the text “Hellope!”.

From https://odin-lang.org/docs/install/:

Notes for Linux:: The compiler currently relies on the core and shared library collection being relative to the compiler executable. Installing the compiler in the usual sense (to /usr/local/bin or similar) is therefore not as straight forward as you need to make sure the mentioned libraries are available. As a result, it is recommended to simply explicitly invoke the compiler with /path/to/odin in your preferred build system, or add /path/to/odin to $PATH.

And I'm pretty sure that only the compiler is installed, the libraries aren't: https://github.com/termux/termux-packages/blob/0d95692efb238f6da4b8cae4dde7bc4e020215c4/packages/odin/build.sh#L31-L33

This seems to be the case. I did the following:

git clone https://github.com/odin-lang/Odin
cd Odin
git checkout dev-2022-04 # to have the matching version
cp $(which odin) .

Now, when I compile an Odin file with this copy of the compiler, it works correctly. However, when I run the produced executable, I get a new error:

error: Android 5.0 and later only support position-independent executables (-fPIE).

However, when I run the produced executable, I get a new error:

This is the odin code that you've compiled? If yes, the error happens because the odin compiler isn't producing position-independent executables (-fPIE) and probably it doesn't support PIE executables: https://github.com/odin-lang/Odin/issues/919
