【问题描述】:
在实现发布和读取网页数据的程序(使用 C++)时,在编译期间链接 curl 时出现以下错误:
error LNK2019: unresolved external symbol __imp__curl_easy_cleanup referenced in function "public: __thiscall WebBrowser::WebBrowser(struct HWND__ *)" (??0WebBrowser@@QAE@PAUHWND__@@@Z) error LNK2019: unresolved external symbol __imp__curl_easy_perform referenced in function "public: __thiscall WebBrowser::WebBrowser(struct HWND__ *)" (??0WebBrowser@@QAE@PAUHWND__@@@Z) error LNK2019: unresolved external symbol __imp__curl_easy_setopt referenced in function "public: __thiscall WebBrowser::WebBrowser(struct HWND__ *)" (??0WebBrowser@@QAE@PAUHWND__@@@Z) error LNK2019: unresolved external symbol __imp__curl_easy_init referenced in function "public: __thiscall WebBrowser::WebBrowser(struct HWND__ *)" (??0WebBrowser@@QAE@PAUHWND__@@@Z)
我正在使用 Visual Studio 2008 并使用此命令进行构建:
nmake /f Makefile.vc mode=static WITH_SSL=static WITH_DEVEL=C:\OpenSSL-Win32 VC=X ENABLE_SSPI=no ENABLE_IDN=no ENABLE_WINSSL=no DEBUG=no MACHINE=x86 GEN_PDB=no ENABLE_IPV6=yes
值得注意的是,我使用2015 Visual Studio 构建包7.47.0。
在项目配置对话框中添加库:
Project->Properties (or Alt+F7),->Configuration properties->Linker->Input->Additional library dependencies.
Project->Properties (or Alt+F7),->Configuration properties->Linker->General->Additional library directories
我该如何解决这个问题?
