我试图在'开箱即用'的操作系统上运行BeagleBone Black上的一些程序但是在使用gcc编译时我一直遇到问题。在尝试编译简单的hello world程序时，最好地说明了这一点：
#include <stdio.h>
int main(void)
{
printf("Hello World\n");
return 0;
}
编译和运行它的输出是：
debian@beaglebone:~$ g++ helloworld.c -o test
debian@beaglebone:~$ ./test
Hello World
debian@beaglebone:~$ gcc helloworld.c -o test
debian@beaglebone:~$ ./test

我的gcc和g ++版本是：

以前有人遇到过这个问题吗？我已经浏览了一下，但没有一个修复程序似乎适用。在此先感谢。
编辑：gcc -v helloworld.c -o outputFile

答案 0 :(得分：1)
秘密在详细的编译器输出中显示：
COLLECT_GCC_OPTIONS =' - E'[...]
-E激发GCC只是为了预处理输入，因此生成的'test'文件实际上是输入文件，其中包含单个include（递归）。
由于你没有明确地添加-E参数，所以gcc显然是这样做的。根据{{3}}对gcc.gnu.org的讨论，你的gcc版本似乎编译了这个，所以我假设你必须从固定的源代码重新编译gcc - 或从任何来源获得正确编译的gcc版本（Debian存储库？）。

您可以尝试使用\gcc代替gcc。前导反斜杠告诉shell忽略任何可能影响同名可执行文件的别名。您也可以使用完整的gcc路径来实现相同的目标。
您还可以使用type gcc，whatis gcc或which gcc或甚至使用较低级别set|grep gcc来检查没有名为gcc的别名或函数。
