다음과 같은 증상은 standard C 에 포함되지 않는 함수를 사용하여 발생하는 에러 이다. 위에서 발생한 에러는 libc.a 정적 라이브러리를 추가해 주어야 한다. 해결 방법으로는 AVR studio 4에서 설정하는 방법과 Makefile 를 수정하는 방법이 있다. Avr studio 4 IDE에서 설정을 하고 바뀐 Makefile 파일을 확인하는 방법으로 두가지 해결방법을 확인해 보고자 한다.
- Step1
“Edit Current configuration option” tool box 클릭한다.
- step 2
클릭하면 project option 팝업창이 나타난다. Libraries tool BOX 를 선택하면 아래와 같은 설정 창을 확인 할수 있다.
- Step 3
- 라이브러리가 있는 폴더를 선택한다.
- 폴더에 포함되어 있는 정적라이브러리중 libc.a를 선택한다.
- 라이브러리를 선택하고 Add Library à 버튼을 클릭한다.
- 확인 버튼을 클릭한다.
- Step 4
” build Active configuration” 버틀을 클릭하여 빌드 확인한다.
- Step etc 1
