Toolchain

Phoenix-RTOS provides its toolchain, based on GNU CC. It's divided into the following parts

  • arm-phoenix
  • i386-pc-phoenix
  • riscv64-phoenix
  • sparc-phoenix

Each part delivers the tools required to compile the given architecture simply. There are a few reasons why that is helpful

  • You can easily compile source code for a given Phoenix-RTOS platform, for example, ia32-generic-qemu:

bash i386-pc-phoenix-gcc helloworld.c

  • You don't need to use many of the compiler switches

  • You can check if a program is compiled for Phoenix-RTOS or not, using phoenix or __phoenix__ flag

#ifdef phoenix
    #warning OS is Phoenix-RTOS
#endif
