求助一个C连接Mysql的问题

编译命令：
gcc test.c -o test -I/home/zorro/soft/libmysql/include -L/home/zorro/soft/libmysql/lib -static -lmysqlclient -lpthread -lm

可以编译成功，但是会产生以下警告：

1. /home/zorro/soft/libmysql/lib/libmysqlclient.a(mf_pack.c.o): In function `expand_tilde':
   
2. /export/home2/tmp/cteam/bs/connector-c-32bit/src/mysql-connector-c-6.0.2/mysys/mf_pack.c:390: warning: Using 'getpwnam' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking

楼主可以检查一下，如果你的mysql是编译安装的，库是否在ld.so.conf的加载范围内，如果没有，请在ld.so.conf添加库的位置，然后运行ldconfig后，再尝试，或者对mysql库做软件连接到默认的库存放位置。

是这样的  我如果使用静态链接就会警告   但是也能编译

如果使用动态链接  就没有问题
