Duplicate functions in Rust sample

------ Compiling dev 'Rust' ------
*** ERROR compiling pkg:/source/rust-wasm.out.brs:
SUB or FUNCTION defined twice. (compile error &had) in pkg:/source/rust-wasm.out.brs(163) 'w2b__start'


=================================================================
An error occurred while attempting to compile the application's components:
-------> Compilation Failed.
pkg:/source/rust-wasm.out.brs
SUB or FUNCTION defined twice. (compile error &had) in pkg:/source/rust-wasm.out.brs(163) 'w2b__start'

Did this sample used to function? I'm trying to figure out why this is happening

Hmm, can you post the built file? Also just make sure you don't have any other .brs files in there with a w2b__start function defined

[iBicha]

Yeah I can see w2b__start twice in the generated code. In another test where I had two functions (main and another one) both were duplicated.

It looks like something might have changed with the rust compiler and it's now exporting functions with the same names. Most likely a problem with wasm2brs where it needs to check export names or pre-pend something. I believe you can remove the following lines from your file:

' export: 'w2b' '' '_start'
Function w2b__start()
  Return w2b__start_command_export_1562511516()
End Function
' export: 'w2b' '' 'main'
Function w2b_main(p0 As Integer, p1 As Integer)
  Return w2b_main_command_export_1255868340(p0, p1)
End Function

Those generated functions seem to be only there for exports. I'll have to spend a bit of time going back through and understanding why this is, but for now hopefully that can unblock you (obviously gross having to delete that every time).
