在编译之前要把：stdsoap2.c soapC.c md5.c dom.c mecevp.c smdevp.c threads.c wsaapi.c wsseapi.c soapClient.c 把这些.c 还有有些配套的.h 拷贝到当前工作目录下。
如果出现以下错误要在编译的时候加：-DWITH_OPENSSL
/tmp/cccao7U5.o：在函数‘soap_mec_init’中：
mecevp.c:(.text+0xe)：对‘soap_ssl_init’未定义的引用
/tmp/ccV2yl3Q.o：在函数‘soap_smd_init’中：
smdevp.c:(.text+0x24c)：对‘soap_ssl_init’未定义的引用
编译：gcc -o test get_GetCapabilities_test.c stdsoap2.c soapC.c md5.c dom.c mecevp.c smdevp.c threads.c wsaapi.c wsseapi.c soapClient.c -I import/ -DWITH_OPENSSL -lssl -lcrypto -ldl
结果：成功得到我们想要的媒体地址
