Q: Does Scala Native support WebAssembly?

A: Support for WebAssembly is out of scope for the project. If you need to run Scala code in the browser, consider using Scala.js instead.


When compiling your Scala Native project, the linker ld may fail with the following message:

relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC

It is likely that the LDFLAGS environment variable enables hardening. For example, this occurs when the hardening-wrapper package is installed on Arch Linux. It can be safely removed.
