本人在本地编写了一个go程序,使用了beego框架,环境如下:
```
[root@ test]# go version
go version go1.6 linux/amd64
[root@ test]# uname -a
Linux . 2.6.32-431.el6.x86_64 #1 SMP Fri Nov 22 03:15:09 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
```
讲编译好的程序仍在了服务器上,main函数都没有进,就出来段错误,使用valgrind跟踪如下:
```

```
服务器的环境如下:
```
[root@slave5]# uname -a
Linux slave5 2.6.32-504.el6.x86_64 #1 SMP Tue Sep 16 01:56:35 EDT 2014 x86_64 x86_64 x86_64 GNU/Linux
```
比较奇怪的是,使用ldd命令检查程序的依赖
本地结果如下:
```
[root@ test]# ldd ./test
linux-vdso.so.1 => (0x00007fff612fe000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x00000030f3200000)
libc.so.6 => /lib64/libc.so.6 (0x00000030f2e00000)
/lib64/ld-linux-x86-64.so.2 (0x00000030f2600000)
```
而上传到服务器上,结果却变成了如下:
```
[root@slave5 home]# ldd ./test
static linked
```
偶尔也出现
```
[root@slave5 home]# ldd test
/usr/bin/ldd: line 118: 120221 Segmentation fault (core dumped) LD_TRACE_LOADED_OBJECTS=1 LD_WARN= LD_BIND_NOW= LD_LIBRARY_VERSION=$verify_out LD_VERBOSE= "$@"
```
而服务器上并不缺共享库,以前部署上去的go程序都可以正常跑。
补充说明:
在服务器上使用readelf -h命令查看elf文件头
本地是正常的,但到了服务器上就会出现
readelf: Error: no .dynamic section in the dynamic segment
为什么会这样??
各位大侠,这是什么问题啊?求助!!!
