Linker 在Linux上使用GNU makefile链接protobuf库

我知道protobuf库必须使用GNU makefile标志

-lprotobuf-lpthread

或

-l:libprotobuf.so-lpthread

链接；但是，当我使用

-Wl、-verbose

生成

时，我会看到以下输出：

attempt to open /usr/lib/gcc/x86_64-redhat-linux/4.1.2/libprotobuf.a failed
attempt to open /usr/lib/gcc/x86_64-redhat-linux/4.1.2/libprotobuf.a failed

/usr/bin/ld: cannot find -lprotobuf
collect2: ld returned 1 exit status
make: *** [playfun] Error 1

并使用
-l:libprotobuf.so-lpthread
：

/usr/bin/ld: cannot find -l:libprotobuf.so
collect2: ld returned 1 exit status
make: *** [playfun] Error 1

我知道我已经安装了Google protobuf库：

$ locate libprotobuf
/usr/lib/libprotobuf.so
/usr/lib/libprotobuf.so.6
/usr/lib/libprotobuf.so.6.0.0
/usr/lib64/libprotobuf.so
/usr/lib64/libprotobuf.so.6
/usr/lib64/libprotobuf.so.6.0.0

所讨论的代码是位于的“tasbot”（learnfun/playfun）项目；以下是我尝试为我的构建（CentOS 5.8）定制的makefile，并精简为SSCCE：

# Makefile made by tom7.

# tasbot
