tcc on musl/arm64

I am trying out tcc in a chroot on an ARM64/Ampere VPS. I emerge tcc (I unmask the ~arm64 keyword). I make a simple hello world program. Compile it with tcc -o hello hello.c. But When I run ./hello, I get 'Segmentation fault (core dumped)'. When I do tcc -run hello.c it works though.

Any idea?

tcc does not support ARM architecture. It only support X86

It says in their README that they support ARM. I just made a test directly on my raspberry pi with tcc and it worked. I don't know why it doesn't work in the chroot in the Ampere VPS...

Edit: also worked in the Ubuntu host for the Ampere VPS.

So I was outdated :oops:

For a long time it did not support ARM

On the chroot environment have you check the binary code type?

If it crashes with a segmentation fault, then the next step is to debug it to understand what memory it tried to access and why it did that instead of what it should have done.
