私が行っている組み込みプロジェクトがあり、そのために Vim と YCM を使用したいと考えています。簡単なプロトタイプとして次のコードを用意しました。
#include <avr/io.h>
#define USART_BAUDRATE 9600
#define BAUD_PRESCALE (((F_CPU/(USART_BAUDRATE*16UL)))-1)
int main(void){
char recieved_byte;
UCSR0B |= (1<<RXEN0) | (1<<TXEN0);
UCSR0C |= (1<<UCSZ00) | (1<<UCSZ01);
UBRR0H = (BAUD_PRESCALE >> 8);
UBRR0L = BAUD_PRESCALE;
for(;;){
// wait until a byte is ready to read
while( ( UCSR0A & ( 1 << RXC0 ) ) == 0 ){}
// grab the byte from the serial port
recieved_byte = UDR0;
// wait until the port is ready to be written to
while( ( UCSR0A & ( 1 << UDRE0 ) ) == 0 ){}
// write the byte to the serial port
UDR0 = recieved_byte;
}
return 0; /* never reached */
}
これは `.ycm_extra_conf.py 用です

# 'flags' list of compilation flags. Notice that YCM itself uses that approach.

# THIS IS IMPORTANT! Without a "-std=<something>" flag, clang won't know which
# language to use when compiling headers. So it will guess. Badly. So C++
# headers will be compiled as C headers. You don't want that so ALWAYS specify
# a "-std=<something>".
# For a C project, you would set this to something like 'c99' instead of
# 'c++11'.
'-std=c99',
# ...and the same thing goes for the magic -x option which specifies the
# language that the files to be compiled are written in. This is mostly
# relevant for c++ headers.
# For a C project, you would set this to 'c' instead of 'c++'.

問題は、ファイルを編集するときに、AVR レジスタのすべてのインスタンス (で定義されavr/io.h
ていて、その後の場所が.ycm_extra_conf.py
ファイルで参照されていると思っていた) にundeclared identifier
.
私は Arch Linux を使用しており、ATMega328p をプログラミングしています。
私は何を間違っていますか?
