Compiler Flags

The compiler flags are automatically configured based on the OS and its environment to ensure the correct context switching mechanism (e.g., C, setjmp/longjmp, or C).

Typical flags include:

  • -DCORO_UCONTEXT (used when ucontext.h is available)

  • -DCORO_SJLJ (used for setjmp/longjmp based switching)

  • -DCORO_ASM (used for assembly-based switching)

  • -DCORO_PTHREAD (used when C are required)

  • -D_FORTIFY_SOURCE=0 (often required for setjmp/longjmp stability)

The actual flags applied are determined at build-time by detecting the target platform and specific system requirements (such as thread support and stack alignment).

Flags starting with -D can be retrieved from defines field without the -D prefix.
