Question

我正在尝试编译运行OpenTLD项目所需的mex文件。

使用：

OpenCV 2.4.9 64位， Matlab 2013b 64位

尝试运行compile.m时，出现以下错误。

Unable to complete successfully.

Error in compile (line 32)
    eval(['mex lk.cpp -O' include lib]);

我知道它与使用其中一个OpenCV或Matlab的错误位版本（32/64）有关，但仍然无法解决问题。

我能够解决这个问题，因为我使用的是最新版本的Matlab，2013b，这是一些语法问题。有趣的是，所有在线论坛都指出了我对32-64位问题的看法。无论如何，我在这里发布解决方案，以便将来它可以帮助某人。

这是我在compile.m中做的修改。第25-30行：

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

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

它之前没有正确读取变量lib中的.lib文件，因此链接错误。

编译OpenTLD compile.m时出错
