How to install kcachegrind / qcachegrind on Mac OSX

Georgiana — Fri, 30 Mar 2012 10:27:17 +0000

Installing kcachegrind via macports takes a long time because it has to build KDE, as well.

An alternative faster way is described below.

download Qt binary and install it
download and install graphviz; I used brew install graphviz
fix default graphviz location by symlinking to a place where cachegrind will find it sudo ln -s /usr/local/bin/dot /usr/bin/dot
qmake -spec 'macx-g++'; make
copy generated qcachegrind.app to your Applications folder
enjoy!

Howto delete a branch in git

Georgiana — Wed, 07 Mar 2012 18:29:48 +0000

Delete a branch that’s already fully merged in its upstream branch, or in HEAD if no upstream was set with –track or –set-upstream.
git branch -d feature/not-needed-anymore

If you don’t want to bother with the merge status of the branch simply use.
git branch -D feature/not-needed-anymore

Download the latest Xdebug version. The most stable is currently 2.1.3, but if you’re brave you’ll use
```
xdebug-latest.tgz
```
directly.
cd /tmp/ && curl http://xdebug.org/files/xdebug-2.1.3.tgz > xdebug.tgz tar -xvzf xdebug.tgz cd xdebug-2.1.3
configure it with phpize
phpize
specify some mac-specific environment variables
MACOSX_DEPLOYMENT_TARGET=10.7 CFLAGS="-arch i386 -arch x86_64 -g -Os -pipe -no-cpp-precomp" CCFLAGS="-arch i386 -arch x86_64 -g -Os -pipe" CXXFLAGS="-arch i386 -arch x86_64 -g -Os -pipe" LDFLAGS="-arch i386 -arch x86_64 -bind_at_load" export CFLAGS CXXFLAGS LDFLAGS CCFLAGS MACOSX_DEPLOYMENT_TARGET
build and install
./configure make sudo make install
enable it in php.ini
[xdebug] xdebug.profiler_output_dir = /var/log/xdebug xdebug.overload_var_dump = 0 xdebug.profiler_output_name = callgrind.out.%R
restart your Apache

OSX list USB devices (lsusb equivalent)

Georgiana — Sat, 26 Nov 2011 11:35:50 +0000

Linux users have the lsusb command to list all their usb devices.
The Mac OSX command line equivalent is
system_profiler SPUSBDataType

For a visual alternative in Lion, the steps are:

click the apple in the top left corner
choose About This Mac
click on the More Info… button to access the System Information application
click on the System Report… button
under Hardware group, there’s the USB option that we were searching for

I needed this information to access my HTC phone with Android that I had connected via USB.
