what kind of console are you using? Something is wrong with output...
Please check project properties/run/console type and try different values.
Application output should never go to gdb log. Maybe the problem is this.

should be fixed with the fix of bug 193230, also please try standard output as console type and reopen if still valid

NetBeans IDE Build 201012150001

When I select "Standard Output", it's fine, but I'm still getting the same faulty behaviour when I select "Internal Terminal" or "External Terminal":

internal terminal is not supported on freeBSD yet, use standard output as a workaround

Well I really don't mind, because it doesn't bother me much. But just for information, this was working fine up to NetBeans 6.9.1 (included).

in 6.9.1 default console type for remote mode was "standard output", in 7.0 it was changed to "internal terminal".

Currently FreeBSD is not in the list of NB supported platforms. The bug will be fixed if time permits.
