Sphinx 编译的问题及解决办法（sphinxclient.c:1358: error: ‘SO_NOSIGPIPE’ undeclared）

编译sphinx库 —-libsphinxclient遇到的错误如下：

A错误: sphinxclient.c:1358: error: ‘SO_NOSIGPIPE’ undeclared (first use in this function)

B错误: .libs/libsphinxclient.a(sphinxclient.o): In function `vi     sphinxclient.cset_error’:

解决这两个问题都需要修改sphinxclient.c 文件,如下所示：

A错误详细表述：
[root@localhost libsphinxclient]# make
make  all-am
make[1]: Entering directory `/usr/local/src/sphinx-1.10-beta/api/libsphinxclient’
/bin/sh ./libtool –mode=compile –tag=CC gcc -DHAVE_CONFIG_H -I. -I. -I.     -g -O2 -c -o

sphinxclient.lo sphinxclient.c
 gcc -DHAVE_CONFIG_H -I. -I. -I. -g -O2 -c sphinxclient.c  -fPIC -DPIC -o .libs/sphinxclient.o
sphinxclient.c: In function ‘net_connect_get’:
sphinxclient.c:1358: error: ‘SO_NOSIGPIPE’ undeclared (first use in this function)
sphinxclient.c:1358: error: (Each undeclared identifier is reported only once
sphinxclient.c:1358: error: for each function it appears in.)
make[1]: *** [sphinxclient.lo] 错误 1
make[1]: Leaving directory `/usr/local/src/sphinx-1.10-beta/api/libsphinxclient’
make: *** [all] 错误 2

A错误解决方法一：SO_NOSIGPIPE 改为 0  (编译通过了 ，但是在运行程序的时候，ERROR: setsockopt() failed: Protocol not available . 所以此方法不得行，抛弃，有需要重新编译，抓狂！)

A错误解决方法二：

红色表明为更改内容

#ifndef _WIN32

        if ( setsockopt ( sock, SOL_SOCKET, SO_NOSIGPIPE, (void *)&optval, (socklen_t)sizeof(optval) ) <

0 )
        {
                set_error ( client, “setsockopt() failed: %s”, sock_error() );
                return -1;
        }
#endif

改为

#if defined(SO_NOSIGPIPE)
        if ( setsockopt ( sock, SOL_SOCKET, SO_NOSIGPIPE, (void *)&optval, (socklen_t)sizeof(optval) ) <

0 )
        {
                set_error ( client, “setsockopt() failed: %s”, sock_error() );
                return -1;
        }
#endif

B错误详细表述：

B错误解决办法 #define vsnprintf _vsnprintf 改为//define vsnprintf _vsnprintf  （注释掉了）
