> Since it's a buildroot toolchain compiled from source in case of native
aarch64 builds.
After seeing the following line in `setup.sh` in this repository, I have
been experimenting with using the standard apt toolchain on an aarch64 host:
```
apt update && apt -y install gcc-aarch64-linux-gnu gcc-arm-linux-gnueabihf
```
When I tried to apt install `gcc-aarch64-linux-gnu` I got the following
message:
```
Note, selecting 'gcc' instead of 'gcc-aarch64-linux-gnu'
gcc is already the newest version (4:12.2.0-3).
```
So this lead me to create PR #137.
> Can you try following diff instead?
It's force-pushed and I will try it out in my aarch64 Debian VM.
Please note the two commented-out lines in
`examples/acipher-rs/ta/build.rs`. They set the following two linker options,
which I suspect are necessary for proper TA operation (but have not tested yet):
```
--sort-section=alignment
--dynamic-list=dyn_list
```
This PR is meant to document my work-in-progress and to stimulate
discussion, it is a "very drafty" DRAFT.
Note that I am new to OP-TEE, relatively new to Rust, have not used Rust in
embedded environments before and am not knowledgeable about these linker
options, so I'm experimenting and learning as I go along...
