When I try to compile any Nim file with --os:any I get this error:
osalloc.nim(218, 10) Error: Port memory manager to your platform
Why does this error pop up and how can I fix it?
In addition, when I try to compile with -d:useMalloc and --mm:orc/arc/none it does work. However, it only works for files that don't import the os module. How do I compile with --os:any even with the os module imported?
--os:any basically means: no OS support. It is generally used for writing kernels or bare metal microcontroller code where no OS is available. Therefore, it it expected that the os module, which provides access to OS services, is not available for os:any.
Furthermore, Nim uses a custom memory allocator. If it is not implemented for your platform (such as os:any), you can ask nim to use the platform's malloc if is available by passing -d:useMalloc to the nim compiler.
