FYI, last I checked, all that command did was update a symlink so that (from memory, not on a Mac right now) /usr/bin/gcc was a symlink to one or the other of /usr/bin/gcc2 or /usr/bin/gcc3. Given that both binaries should be available regardless of where the symlink is pointing, maybe any tests could work directly with the files rather than the link. -- Chris Devers[EMAIL PROTECTED]

Mac::Processes can give you much of the information you could want. It provides a PSN instead of a PID, but I could add GetProcessPID() and GetProcessForPID() to Mac::Processes, which maps between the two. Take a look at the module and see if there's anything else there you need that it doesn't provide. :-) Let me know, or file a report on SourceForge.net. -- Chris Nandor [EMAIL PROTECTED]http://pudge.net/ Open Source Development Network[EMAIL PROTECTED] http://osdn.com/

I don't know how much use Mac::Processes will be to you for this, but I went ahead and added the two functions for the next release. I know I've wanted the functionality before. $ perl -MMac::Processes -e '$psn = GetCurrentProcess(); printf %d == %d, %08X == %08X\n, GetProcessPID($psn), $$, $psn, GetProcessForPID($$)' 1862 == 1862, 015A0001 == 015A0001 -- Chris Nandor [EMAIL PROTECTED]http://pudge.net/ Open Source Development Network[EMAIL PROTECTED] http://osdn.com/
Re: Process table information
Well, If we were running linux we could look in /proc. Possible solutions: 1) Get the source for darwin and study the code for the ps command. 2) Study the header files to find the format for the proc table, examine the kernel symbol table to get the start address of the proc table. Write code that fetches the table from /dev/kmem and parses it. ( I have done this with some other unix systems...). proc.h might be a good starting point. Regrettably sysctl does not give access to table info in the kernel. --Jerry Hey, I was thinking about working on Proc::ProcessTable to get support for OS X.

Source code and commentary: http://developer.apple.com/qa/qa2001/qa1123.html You can get a list of all BSD processes, which includes daemon processes, using the BSD sysctl routine. Code for doing this is shown in Listing 1. When using this code you should note the following. * The returned kinfo_proc structures contain a huge amount of information about the process, including the process ID (in kp_proc.p_pid) and the process name (in kp_proc.p_comm). * As far as BSD is concerned all Classic applications run within a single process. * You do not need any special privileges to make this sysctl; any user can get a list of all processes on the system. * The UNIX Programming FAQ lists a number of alternative ways to do this. Of these, the only approach that works on Mac OS X is exec'ing the ps command line tool. exec'ing ps will require parsing the tool's output and will not use system resources as efficiently as Listing 1. -- Chris Nandor [EMAIL PROTECTED]http://pudge.net/ Open Source Development Network[EMAIL PROTECTED] http://osdn.com/

What I could try to do is release binaries next time, putting them on SourceForge.net (I won't bother putting them on the CPAN). I think those should work on 10.1.5. Let me know if you want me to try (I am aiming for a 0.02 release of Mac::Carbon in the next 2 weeks). For what it's worth, I had to sudo gcc_select 3 to get Mac::Carbon to compile under 10.2.2. Having changed gcc to 2 in order to get curses.pm to work properly I was head-scratching for a couple of minutes when Mac::Carbon wouldn't compile; then I noticed the 2.95.2 in the output. So I think Ken's on the money here.
