1 GHC
| Problem | Solution | Examples |
|---|---|---|
| compiling and linking an executable | --make | ghc -- make Main.hs --> Main |
| compiling a file, without linking | -c | ghc -c Foo.hs --> Foo.hi, Foo.o |
| generating Assembler code | -S | ghc -S Foo.hs --> Foo.hi, Foo.s |
| generating C code | -S | ghc -C Foo.hs --> Foo.hc, Foo.hi |
| linking files into an executable | -o | ghc -o test Foo.o Bar.o Baz.p --> test |
