每次執行結束都會出現下面訊息, 想請教出現 Error 40 是正常的嗎?

arm-linux-gnueabihf-gcc -c -O1 -Wall -o fib.o fib.s
arm-linux-gnueabihf-gcc -fno-stack-protector -o fibseq fibseq.o fib.o
qemu-arm -L /usr/arm-linux-gnueabihf ./fibseq
Please input a number:30
The fibonacci sequence at 30 is: 832040
make: *** [qemu] Error 40

Please leave the related messages rather than mix the functional code and questions.

Sorry, 我已修正, 下面是本來的錯誤訊息.

arm-linux-gnueabihf-gcc -c -O1 -Wall -o fibseq.o fibseq.c
fibseq.c: In function ‘main’:
fibseq.c:11:8: warning: ignoring return value of ‘scanf’, declared with attribute warn_unused_result [-Wunused-result]

Fixed in latest GIT. You can perform git rebase.

已經使用 git rebase 把 fix 部分合併

[Eddy0402]

這應該是main function沒有return的關係吧
補上return 0或是以c99模式編譯就沒有這個error了

@Eddy0402 yes, 前面已經修正了
