SUMMARY | |
I like to use kcachegrind for doing profiling on my ruby code. Most of my development | |
is done on OSX, and while you can install kcachegrind via macports, it takes forever | |
because it has to build KDE, as well. Much to my surprise, the fine folks who | |
wrote kcachegrind also made a QT version, qcachegrind. I was able to build this on | |
OSX without too much effort, only having to install QT and GraphViz. Yippie! | |
I'm running OSX 10.6.7, with Xcode 4. My default gcc/g++ version is 4.2. I'm sure | |
it will build just fine on earlier versions of Xcode, but I haven't tested it. |
