cdrecord supports DVD and BluRay writing. ftp://ftp.berlios.de/pub/cdrecord/alpha/ Cdrecord introduced DVD writing in February 1998 - 11 years ago. The related code was made OpenSource 3 years ago. J”rg Schilling 19th February 2009 The test for __int64 is _expected_ to fail on all platforms but Win32/Microsoft C The most well known problem on OS2 is GNU make. GNU make mas many bugs on platforms that use as line delimiter and on platforms that use '\\' as file name delimiter. If you don't have smake, I recommend you to download the complete schily source sonsolidation from: ftp://ftp.berlios.de/pub/schily/ it automatically compiles smake first before continuing with the rest.
