It sounds like something is doing a #define min(...) ... #define max(...) ...
hat's not really a nice thing to do. It's not a namespace, it's macro issue. If you need to include these files before the OCRopus files, you need to #undef min #undef max before including the OCRopus include files. I've renamed the THREAD identifiers in glutils.h to help avoid conflicts. You should be able to include OCRopus before the other files now.
