系统是redhat 6.4， 请问大家有什么好的建议吗？
thx！

packetdrill.o 是64位还是32位的？

这真的有点奇怪，/lib64下确实有libpthread.so的啊，用ldconfig检查过吗？

$ ldconfig -p | grep pthread
        libpthread.so.0 (libc6,x86-64, OS ABI: Linux 2.6.1 => /lib64/libpthread.so.0
        libgpgme-pthread.so.11 (libc6,x86-64) => /usr/lib64/libgpgme-pthread.so.11
        libgpgme++-pthread.so.2 (libc6,x86-64) => /usr/lib64/libgpgme++-pthread.so.2

有没有试过编译一个简单的程序连接-lpthread？

你用了”-static“，就表示要链接静态库，应当找libpthread.a。

1. locate libpthread.a

复制代码
