site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com Anyway, when I run gdb, the LIST command fails with the following error: (gdb) list 1 {standard input}: No such file or directory. in {standard input} This also fails: (gdb) list test2.c:1 No source file named test2.c. This also fails: (gdb) list func1 No line number known for func1. Here is my make file: CC = gcc CFLAGS = -g LFLAGS = -g INLCUDE = . test2: test2.o $(CC) $(LFLAGS) -o test2 test2.o test2.o: test2.c $(CC) -I$(INCLUDE) $(CFLAGS) -c test2.c Thanks in advance. _______________________________________________ Do not post admin requests to the list.

I am using OSX 10.4.9 and XCode 2.4.1 installed although I am running gdb on the command line so I'm not sure if that matters. I have a very simple app with one .c file. I am building with the -g switch What could I be doing wrong? This works perfectly on Linux. It even fails if a supply the complete path to the source file. This is VERY frustrating so any help would be greatly appreciated. I'm sure it is a simple mistake on my part, but google searches have yielded nothing This email sent to site_archiver(a)lists.apple.com

Right now I'm trying to see how I can register both VNODE and PROC for use with one single kqueue. However, I've had two kernel panics this morning. First kernel panics I've had on my MacBook since I bought it. I'm suspecting something's up possibly with my code. If anyone would look at my code below and comment about it, that'd be appreciated! EV_SET( &changelist[ 0 ], fd, EVFILT_VNODE, EV_ADD | EV_ONESHOT, NOTE_DELETE | NOTE_EXTEND | NOTE_WRITE | NOTE_ATTRIB, 0, 0 ); EV_SET( &changelist[ 1 ], 1, EVFILT_PROC, EV_ADD | EV_ONESHOT, NOTE_EXIT | NOTE_FORK | NOTE_EXEC | NOTE_TRACK, 0, 0 ); if( eventlist[ 0 ].fflags & NOTE_EXTEND || eventlist [ 0 ].fflags & NOTE_WRITE ) { printf( "File modified.\n" ); } This email sent to site_archiver(a)lists.apple.com

Rosetta is not open source and is not part of Darwin, so it is off-topic for any of the Darwin mailing lists. 2. One should not cross-post to more than one mailing list at a time.

The preferred method for all sysctls going forward is to use sysctlbyname(), so that's what you should use in new code. The reason you get two of these is that one is by mib (and knowledge is built into the sysctl command line tool) and the other is iterated from the information in the kernel. Eventually, the mib-based one will go away. This email sent to site_archiver(a)lists.apple.com
