编译支持证书openssl库的问题

编译支持证书openssl库的时候，出现DSO linker问题

/usr/bin/ld: /tmp/ccXEDaF2.o: undefined reference to symbol 'X509_free'
/usr/bin/ld: note: 'X509_free' is defined in DSO /lib64/libcrypto.so.10 so try adding it to the linker command line
/lib64/libcrypto.so.10: could not read symbols: Invalid operation
collect2: ld returned 1 exit status
make: *** [echart] Error 1

检查一下是否支持该选项

[root@41-dev src]# readelf --symbols /lib64/libcrypto.so.10 |grep X509_free
116: 0000003ed98d19e0 12 FUNC GLOBAL DEFAULT 11 X509_free
2027: 0000003ed98d2b50 12 FUNC GLOBAL DEFAULT 11 NETSCAPE_X509_free

如果支持的话，可以在ld.so.conf,添加/lib64 ,或者使用ldconfig
