Question

所以基本上我是在Visual Studio 2019 Windows 10上编写32位程序的。我希望程序包含libconfig，但是每次编译它时，都会遇到“函数_main中引用的未解析的外部符号” 我编译并包含libconfig ++。lib作为附加依赖项（调试32位）。我在谷歌上搜索了一段时间，但没有任何东西可以完全帮助我。也许我的设置有问题，因为我在使用某些库时也会得到它们

#include <libconfig/libconfig.h++>

bool logging = true;
bool debug = false;

int main(int argc, char* argv[])
{
libconfig::Config cfg;

const char* cfgFilePathC = "D:\\default.cfg";

cfg.readFile(cfgFilePathC);
std::string dumpName;
int threadPriority;
cfg.lookupValue("logging", logging);
cfg.lookupValue("debug", debug);
cfg.lookupValue("dumpName", dumpName);
cfg.lookupValue("threadPriority", threadPriority);

bool downloadCustomFile, startAfterDownload;
std::string downloadFromUrl, fileName;
cfg.lookupValue("downloadCustomFile", downloadCustomFile);
cfg.lookupValue("downloadFromUrl", downloadFromUrl);
cfg.lookupValue("fileName", fileName);
cfg.lookupValue("startAfterDownload", startAfterDownload);

std::stringhost, user, pass;
cfg.lookupValue("host", host);
cfg.lookupValue("user", user);
cfg.lookupValue("pass", pass);

使用libconfig时显示LNK2019
