gcc - 可以将gcc配置为不在警告/错误消息中打印出完整路径吗？

Question

当gcc打印出警告或错误时，它将显示包含错误的文件的完整路径。是否有一个标志可以将输出缩短为仅文件名？

Answer 1

这仅取决于您如何调用gcc:

/tmp/c$ gcc -Wall bad.cbad.c:1: warning: return type defaults to ‘int’bad.c: In function ‘main’:bad.c:1: warning: control reaches end of non-void function

vs

/tmp/c$ gcc -Wall /tmp/c/bad.c/tmp/c/bad.c:1: warning: return type defaults to ‘int’/tmp/c/bad.c: In function ‘main’:/tmp/c/bad.c:1: warning: control reaches end of non-void function

vs

/tmp/c$ gcc -Wall ../../tmp/c/bad.c../../tmp/c/bad.c:1: warning: return type defaults to ‘int’../../tmp/c/bad.c: In function ‘main’:../../tmp/c/bad.c:1: warning: control reaches end of non-void function

where contents of bad.c are just

main() { }

如果有人在乎。
