为什么我在 C 的枚举中收到“错误：错误指令”？

Question

This is weird and doesn't have any sense to me. I added the following enum in a .h file u-boot:

typedef enum LP5521_Patterns_Tag
{
  LP5521_EB_ALL_GOOD,
  LP5521_EB_CLEAR_ALL,
  LP5521_EB_CONNECTED_TO_INTERNET,
  LP5521_EB_ENERGY_BRIDGE_FOUND,
  LP5521_EB_NO_SIGNAL,
  LP5521_EB_PLUGGED_IN,
  LP5521_EB_POOR_CONNECTION,
  LP5521_EB_SERACH_WIFI,
  LP5521_SET_COLOR,
  LP5521_SET_CURRENT,
  LP5521_SET_COLOR_CURRENT,
  LP5521_PATTERNS_TOTAL
}LP5521_Patterns_T;

But then when I try to compile it I get the following errors:

include/configs/lp5521.h: Assembler messages:
include/configs/lp5521.h:7: Error: bad instruction `typedef enum LP5521_Patterns_Tag'
include/configs/lp5521.h:8: Error: junk at end of line, first unrecognized character is `{'

include/configs/lp5521.h:20: Error: bad instruction `lp5521_patterns_total'
include/configs/lp5521.h:21: Error: junk at end of line, first unrecognized character is `}'

I notice that at the top it says Assembler messages but I don't understand either. There is a .c file that I already added that contain a bunch of typedef enums and I'm not getting any errors in those.

Could anyone please help me to figure out what is going on here?

I don't know if this helps but I'm adding some code to u-boot and cross-compiling for imx6.

Thank you!!

Answer 1

U-boot contains a lot of CPP pre-processed assembly files (ie .S rather than .s ); the board config header is probably the one thing that's included in just about everything (C files, assembly files, linker scripts) as it generally defines not just options but board-specific physical addresses, etc.

Ergo putting anything other than #defined symbols in there is pretty much asking for trouble.

Answer 2

Wrap this enum like this :

  #if !defined(__ASSEMBLER__) 

  typedef enum LP5521_Patterns_Tag
  {
  LP5521_EB_ALL_GOOD,
  LP5521_EB_CLEAR_ALL,
  LP5521_EB_CONNECTED_TO_INTERNET,
  LP5521_EB_ENERGY_BRIDGE_FOUND,
  LP5521_EB_NO_SIGNAL,
  LP5521_EB_PLUGGED_IN,
  LP5521_EB_POOR_CONNECTION,
  LP5521_EB_SERACH_WIFI,
  LP5521_SET_COLOR,
  LP5521_SET_CURRENT,
  LP5521_SET_COLOR_CURRENT,
  LP5521_PATTERNS_TOTAL
  }LP5521_Patterns_T;

  #endif

defining _ ASSEMBLER _ symbol for Assembler and it should work.
