Dear all, I am trying to produce windows native code for windows, to do so I have followed the instructions I found on different sources I am almost done but I get one last error during linking: ** Fatal error: cannot find file "OLDNAMES" File "caml_startup", Line 1, character 0-1 Error: Error during linking I am using windows 7 and MinGW + Windows SDK 6.2 (to get uuid.lib) + masm32 (to have ml.exe) Any idea what might be going wrong? Thanks!!
