LDNS:对变量(C++）的未定义引用

LDNS : Undefined reference to variables ( C++ )

本文关键字：未定义 引用 C++ 变量 LDNS      更新时间：2023-10-16

我是LDNS的新手。我按照它们在自述文件中显示的方法安装ldns。我试着使用他们的示例代码，但每当我使用g++文件.cpp编译它时，我都会收到以下错误。

在MACOS上与Ubuntu一起使用虚拟盒子。

/tmp/ccxvsMSZ.o: In function `main':
dns.cpp:(.text+0x1e): undefined reference to `ldns_dname_new_frm_str'
dns.cpp:(.text+0x33): undefined reference to `ldns_resolver_new_frm_file'
dns.cpp:(.text+0x56): undefined reference to `ldns_resolver_query'
dns.cpp:(.text+0x70): undefined reference to `ldns_pkt_rr_list_by_type'
dns.cpp:(.text+0x80): undefined reference to `ldns_rr_list_sort'
dns.cpp:(.text+0x96): undefined reference to `ldns_rr_list_print'
dns.cpp:(.text+0xa2): undefined reference to `ldns_rr_list_deep_free'
dns.cpp:(.text+0xae): undefined reference to `ldns_pkt_free'
dns.cpp:(.text+0xba): undefined reference to `ldns_resolver_deep_free'
collect2: error: ld returned 1 exit status

知道我可能做错了什么吗？

第页。S.：尝试在MAC上运行代码，但出现以下错误。

编译时指定ldns（-lldns）库。
