三、调试运行Matlab版OpenTLD_unresolved external symbol mexfunction-优快云博客

本文详细介绍了在使用Matlab进行开发时遇到的LNK2019未解析外部符号错误，并提供了具体的解决步骤。通过修改编译脚本中的库文件路径，可以有效解决这一问题。

关键错误：

Unable to complete successfully.

解决办法：

修改文件compile.m. Lines 25-30:为

files = dir(fullfile(libpath, '*.lib'));

lib = [];
for i = 1:length(files),
   lib = [lib ' ' libpath '\' files(i).name];
end
