解决找不到动态库libpthread.so

本文介绍了在使用GCC进行程序编译时遇到的关于pthread动态库链接失败的问题及解决办法。通过修改ld.so.conf文件尝试未果后,最终采用在编译命令中加入-pthread选项成功解决了该问题。

用gcc编译程序时遇到如下问题

/usr/lib64/gcc/x86_64-suse-linux/4.7/../../../../x86_64-suse-linux/bin/ld: note: 'sem_close@@GLIBC_2.2.5' is defined in DSO /lib64/libpthread.so.0 so try adding it to the linker command line
/lib64/libpthread.so.0: could not read symbols: Invalid operation

大致意思说找不到动态库libpthread.so

在网上查了一些资料,有的说要修改/etc/ld.so.conf文件

使用如下命令

vi /etc/ld.so.conf

加入一行

/lib64

不知什么原因这个方法不管用

后来查到直接在gcc编译命令后加“-pthread”

gcc -o test test.c -fPIC -lrt -pthread

-fPIC 编译位置独立的代码,任何位置可以使用,达到共享内存;不仅是共享库,静态库有时也需要有 -fPIC参数   或者查看Makefile是否存在前后配置项不一致;

-lrt将连接库librt.so or librt.a,因为我用了共享内存才需要加的

最后加上“-pthread”后程序能正常编译了
