I'm trying to use GDB (v 7.3.1) from macports to debug an executable compiled with g++ 4.7 (also from macports). However, I start the debugger, I get the following output: GNU gdb (GDB) 7.3.1 Copyright (C) 2011 Free Software Foundation, Inc.

After upgrading to Lion, I get the following error when trying to start up the Postgres server: pg_ctl: could not open PID file "/usr/local/var/postgres/postmaster.pid": Permission denied I also tried to re-run the initdb command, but ran into a similar problem: initdb: could not access directory "/usr/local/var/postgres": Permission denied If it matters, PostgreSQL was installed via Homebrew. Running brew info postgresql yields the expected results (version, summarized docs). Well, it turns out the solution was pretty simple. I changed the group on /usr/local/var to staff (from wheel) and

I have been fiddling around trying to get Eclipse for C++ working on Mac OS X Lion. I have downloaded Xcode 4.3, so there should be a /Developer/usr folder with gcc, g++, make and other compiler commands. However, while I have a /Developer folder, I do not have a /Developer/usr folder anywhere. Where can I get this from? I think it may have disappeared when I attempted to symlink the contents of /Developer/usr/bin to the default /usr/bin for Eclipse to use. Not sure if this can even happen. This has driven me crazy for about a week now! /Developer was moved to /Applications/Xcode.app/Contents

I'm trying to get a table layout as shown below working with view-based NSTableViews that have been introduced in Lion. There were multiple approaches described for cell-based NSTableViews, e.g. Mimic the artwork column , but these don't really apply for view based table views. The idea is that the table gets populated by an array of objects, in one (or more) column spanning rows indicating that objects share some data in common. numberOfRowsInTableView: returns to total number of items (19 in the case of the attached image). Has anyone tried something like this? Layout I was able to do this

I'm testing out an app that I've made which, amongst other things, loads a couple of .png images when opened. The images are displayed correctly on my Mac (10.7.5) and my mother's (10.8.5); however when my sister opens it on hers (10.9.5) the images don't load. All other functionality is otherwise intact. I should note that on my Mac and my mother's, I installed Python 3.4 and many of the packages that the app uses, including the PIL package, whereas my sister has none of these. The app was build using the command: python3.4 setup.py py2app Images are imported in the code with: image = ImageTk

On opening a new terminal window (Mac OSX 10.7.2) and entering rails , I get the always fun 'rails is not currently installed..." message. But I enter rvm use default 1.9.2 and all is good with the world. Where did I go wrong? nobody Zabba is right in the comments when he says the correct command to use is rvm use 1.9.2 --default . RVM considers default to be a Ruby, equivalent to the Ruby set to the default. If I type rvm use default into my terminal, I get this output: $ rvm use default Using /Users/tom/.rvm/gems/ruby-1.9.3-p0 However, there is the ability to list multiple Rubies in your
