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
ldd的显示结果：

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 Worldn");
return
0;
}
在redhat上面编译
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
扫描二维码关注公众号，回复：

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