今天想将redhat上面的程序放到suse 10上面运行，结果遇到了这个错误：

Floating point exception

貌似suse和redhat的binay是不兼容的呢 - -||

用hello world程序测试一下:

#include <stdio.h>
#include <stdlib.h>

int main()
{
	printf("Hello World\n");
	return 0;
}

在redhat上面编译

1

gcc helloworld.c -o helloworld

拷贝到suse上面运行，结果还是出现Floating point exception

Google了一下，发现可以在编译的时候加入-Wl,--hash-style=sysv

1

gcc helloworld.c -Wl,--hash-style=sysv -o helloworld

拷贝到suse上面运行竟然正常了。

Google发现了这样一段话

Fedora (RedHat?) seems to have a different default dynamic linker hash style, I think basically it is: ld –hash-style=gnu ..

So without using one of: –hash-style=both or –hash-style=sysv

The bits created won’t run on systems that don’t support this new hash style, like SuSE 10.

OMG
