Segmentation fault when compile and run a simple code

[jiguorui]

Hi, Thanks a lot for your great works at Rusty.

I compile an example code by rustyc, and run it, but failed with 'Segmentation fault'. the code is same as:

https://github.com/PLC-lang/rusty/blob/master/examples/while_loop_with_continue.st

and I compile it with commond line:

./rustyc --target x86_64-unknown-linux-musl --static test.st

and I got a file named test at x86_64-unknown-linux-musl, it's fine.

But when I run it with

./test

I got a 'Segmentation fault ' always.

How to address this, I try to solve it but failed.

Hello, thank you for your interest in Rusty!
In order to run the test file, you will need to link it with the crt from musl. The Clang compiler usually does this, but our embedded linker cannot.
You have two ways of doing this:

• Use the --linker flag to replace the embedded linker with one of your choice --linker=clang-13
• Compile with -c instead of --static, and then use a compiler of your choice to link the resulting object file.

You can see both compiled files' differences by running nm on them. The first file will only show main while the second one will have additional symbols that get added from including the crt

Hope this helps

Thanks a lot!
It works well. the command line is like:
./rustyc --target x86_64-unknown-linux-musl --static --linker=clang-13 test.st
