There is a guide available which explains how to install AMIX on WinUAE:

I will try that later this week. I'm really curios to learn whether they're
using ELF with 4 bytes alignment.
I have kicked off the installation of AMIX 2.1 on WinUAE now.
It actually looks very streamlined and user-friendly ;-).
Let's see if I can get to compile the sample program and see what the alignment
says.
So, it turns out that AMIX 2.1 uses ELF binaries and indeed 4 bytes alignment.
See the screenshot here: https://people.debian.org/~glaubitz/amix-alignment.jpeg
Please excuse the messed up formatting, I couldn't type backslashes.
Thanks for suggesting to test AMIX, that information is very valuable.
You can use __alignof__() to have the data type alignment:
int main(void)
{
printf("alignof(short) %ld\n", __alignof__(short));
printf("alignof(int) %ld\n", __alignof__(int));
printf("alignof(long) %ld\n", __alignof__(long));
printf("alignof(long long) %ld\n", __alignof__(long long));
}
On x86_64, it gives:
alignof(short) 2
alignof(int) 4
alignof(long) 8
alignof(long long) 8
Thanks,
Laurent
