Can't run a newly compiled of demo/hello

[WattleFoxxo]

When i try to run the newly compiled program i get this error while running:

[ERROR] Error: file depends on following libraries: ["libc.so"]
[ERROR] Unable to load elf64 binary /bin/demo

if i change -pie to -static-pie i get this error while running:

[ERROR] Page Fault (#PF) Exception: ExceptionStackFrame {

Shared libraries are currently not supported. I used a test program, which based on the MUSL C library. Everything is statically linked.

another question, how would make the hello world user space program in rust and compile it?

[stlankes]

Hm, Rust supports also Musl. The target has the name x86_64-unknown-linux-musl. See also https://doc.rust-lang.org/rustc/platform-support.html Consequently, a C library is still the base of the application.

I think that you are able to build pure Rust application with Redox and RustyHermit.

hi sorry to bother you but im still having trouble getting newly compiled elf binaries to load, is there a specific version of the musl-gcc compiler you use?

[stlankes]

Hm, I have to take a look in the code. I don't tested with the latest version of musl. I come back to you.

[stlankes]

In the meantime I know the reason. I compiled musl without SSE support. The latest version doesn't work without SSE support. At least, I am not able to build it. I will take a look to integrate SSE support.
