Thanks Valdis.Looks like the failure is that I can not write to a 2GB buffer (char bf[2GB size]).Where do I get the distro include file?

Your kernel supports it, but your toolchain doesn't until you get an include file that includes the update for MAP_SYNC > Also, how do I make mmap support map size of 2GB or larger, currently the > call to mmap fails with mapsize of 2GB. What error code does it fail with? _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
