I had first change my project from C to rust, but when I almost completed the project, I found my target platform aarch64-unknown-nto-qnx700 is tier 3 support for official Rust team. So, I think I will have to compile such toolchain by myself. However, I googled and search more compile manuals from AI, all method failed for me.
But, I don't want to rewrite my project in C or rollback to C in future. So, any body who has a tested compile solution to share will be very very appreciated.
Thanks all.
