linux - 我在使用mpicc进行编译时遇到技术问题

Question

当我编译'''gcc'''时，我的gcc正常工作，但是我尝试使用'''mpicc'''编译C程序，并且我的终端返回此错误，该错误还会删除脚本:

/usr/lib/gcc/x86_64-linux-gnu/7/../../../x86_64-linux-gnu/Scrt1.o: In function `_start':
(.text+0x20): undefined reference to `main'
collect2: error: ld returned 1 exit status

编译指令为: mpicc -o p35.c。

我该如何解决？

我的gcc版本:

gcc --version
gcc (Ubuntu 7.5.0-3ubuntu1~18.04) 7.5.0

我的mpicc版本:

mpicc --version
gcc (Ubuntu 7.5.0-3ubuntu1~18.04) 7.5.0

谢谢。

Answer 1

编译命令错误

mpicc p35.c -o p35.out

现在运行p35.out文件

./p35.out

我想你明白了。
