What are Pony’s supported CPU platforms?

See supported platforms in the ponyc README.

I get a “requires dynamic” error when compiling, how do I solve it?

/usr/bin/ error: ./fb.o: requires dynamic R_X86_64_32
  reloc against 'Array_String_val_Trace' which may
  overflow at runtime; recompile with -fPIC

try running ponyc with the --pic flag.

For example:

ponyc --pic examples/helloworld

As of Pony 0.17.0, if you are building ponyc from source, you can have --pic automatically set for you. When building ponyc, run the following make command and your generated ponyc binary will always supply --pic without you having to set it.

make default_pic=true

On Windows I get fatal error LNK1112: module machine type 'x86' conflicts with target machine type 'x64'

Only 64-bit Windows is supported.

Make sure you’re running a cmd.exe/powershell.exe that does not include 32-bit VS environment variables.

This error occurs when ponyc is compiled in a 32-bit Visual Studio Developer Command Prompt.
