要用什么库文件才可以编译
含有线程处理的程序
我编译以前用LINUX THREAD的程序出现如下错误!
[root@sky thread]# gcc lifecycle.c -o lifecycle
/tmp/ccaN0qnm.o(.text+0x45): In function `main':
: undefined reference to `pthread_create'
/tmp/ccaN0qnm.o(.text+0x70): In function `main':
: undefined reference to `pthread_join'
collect2: ld returned 1 exit status
请高手帮忙,谢谢!!

加入线程库后如下
[root@sky thread]# g++ lifecycle.c -o lifecycle -lpthread
/lib/libpthread.so.0: undefined reference to `__on_exit@GLIBC_PRIVATE'
/lib/libpthread.so.0: undefined reference to `_errno@GLIBC_2.0'
/lib/libpthread.so.0: undefined reference to `__libc_sigaction@GLIBC_PRIVATE'
/lib/libpthread.so.0: undefined reference to `_h_errno@GLIBC_2.0'
collect2: ld returned 1 exit status

gcc lifecycle.c -o lifecycle -lpthread

请问NPTL的库名同LINUXTHREAD相同?

rainshadow

库名是一样的，NPTL为了兼容linuxthread，所以才使用了和linuxthread一样的库名pthread。
