I tried to build the Tight VNC from Microsoft Visual C++ 6.0, but the compiler complains that it couldn’t find the following file “horizon/horizonMain.h”. Also I tried to search that file from web as well but couldn’t find those file. Please help me what I have to do in order build it successfully. I tried to build the “tightvnc-1_1.3.9_winsrc”. Also if you can please provide me the building process from Microsoft Visual C++ 6.0 in step by step procedure.
