Question

如何在文件名或路径中有空格的文件中设置断点？

GDB似乎无法做到这一点，或者我错过了什么？

/tmp$ g++ -g debugee\ space.cpp 
/tmp$ gdb ./a.out

Answer 1

对我而言，这看起来像是gdb 7.4中的回归。我报告了这个错误：http://sourceware.org/bugzilla/show_bug.cgi?id=13798

Answer 2

适用于我（tm），虽然没有尝试使用c ++ ...

cat space\ spaces.c 
#include <stdio.h>

int tmp(void) {
    int a = 42;
    printf("%d", a);
}

int main(void) {
    tmp();

    return 0;
}

$ gdb -q a.out
