建立交叉编译环境gcc时 输入make 出现如下错误 gcc: ../../build-i686-pc-linux-gnu/libiberty/libiberty.a：没有那个文件或目录 make[2]: *** [build/genmodes] 错误 1 make[2]: Leaving directory `/mnt/gcc' make[1]: *** [all-gcc] 错误 2 make[1]: Leaving directory `/mnt' make: *** [all] 错误 2 请问这个是怎么回事？

[code]#include #include int main() { char *str = "hello, liunx"; printf("Before test fault: %s\n", str); *str = 0; printf("After test fault: %s\n", str); return 0; } [/code]如上述代码，用gcc -g test.c -o test，运行之产生 Before test fault: hello, liunx 段错误 (core dumped) 可用 gcc -g -O2 test.c -o test 运行之 Before test fault: hello, liunx After test fault: hello, liu...
