What does it mean when the ELF fails to build but there are no errors?

under problems is says there are none.
under Terminal is says FAILED: usb2llapi.elf
under that I get I few errors saying already defined. for example

Code: Select all

cmd.exe /C "cd . && C:\Users\Administrator\.espressif\tools\xtensa-esp-elf\esp-13.2.0_20240530\xtensa-esp-elf\bin\xtensa-esp32s3-elf-g++.exe -mlongcalls  -fno-builtin-memcpy -fno-builtin-memset -fno-builtin-bzero -fno-builtin-stpcpy -fno-builtin-strncpy -Wl,--cref -Wl,--defsym=IDF_TARGET_ESP32S3=0 -Wl,--Map=C:/Users/Administrator/Desktop/usb2llapi/usb_host_lib/build/usb2llapi.map -Wl,--no-warn-rwx-segments -fno-rtti -fno-lto -Wl,--gc-sections -Wl,--warn-common -T esp32s3.peripherals.ld -T esp32s3.rom.ld -T esp32s3.rom.api.ld -T esp32s3.rom.libgcc.ld -T esp32s3.rom.wdt.ld -T esp32s3.rom.version.ld -T esp32s3.rom.newlib.ld -T memory.ld -T sections.ld @CMakeFiles\usb2llapi.elf.rsp -o usb2llapi.elf  && cd ."

I’m pretty sure the issue is this h file. Because I was working in it when the issue popped up. but I have the ifdef in there?

Code: Select all

#ifndef _USB2LLAPI_H_
#define _USB2LLAPI_H_

 


#include <stdbool.h> //bug fix I guess?
#define _delay_ms(t) vTaskDelay(t / portTICK_PERIOD_MS);

	unsigned char AUTO_PAUSE_DIABLED;

	unsigned char SWAP_BUTTONS2;
	unsigned char ROTATION_SHIFT;
	unsigned char RANGE_SELECTION;
	unsigned char LATENCY;
} ;
struct ModesStates modes; 



typedef struct 
{
	bool          ( *init)	    (void);
	unsigned char ( *getCommand)(void);

} LLAPIDevice;

Would be helpful if you'd share the actual error messages...

In the header file, you're defining two things:
1. #define _delay_ms(t) - which can make the preprocessor error out if _delay_ms(...) is also #defined at another place,
2. unsigned char psx_pressure_data[12]; ... - defines a variable named psx_pressure_data. You usually don't want to define global variables (and non-static functions) inside a header file because the header file may be included in multiple C files resulting in multiple definitions of the same named entity which is at least problematic.

I was able to figure it out the error was not in the problems tab it was hidden in the output.
