Thus, profiling does not +need any preparation, can cope with shared libraries and plugin +architectures, and allows for profile runs to not influence the measuring +by the profile itself (all in contrast to e.g. GProf). Disadvantage is +slower profile runs, unfortunately. + +For Cachegrind to provide call tree information, a patch is provided. +This enables the most interesting visualization features of KCachegrind. + + +Requirements +------------ + +A call-tree version of Cachegrind: + - X86 Linux + - Valgrind 1.0.x with call-tree patch from KCachegrind Website + - Valgrind 2.0.x with call-tree skin installed + +Cachegrind runs on x86 platforms, KCachegrind on all KDE enabled +platforms (KDE 3.0.x). + + +Compilation and Installation +---------------------------- + +Simple do the command sequence + + ./configure --prefix= + make + make install + + + +KCachegrind features +-------------------- + +Most important: TreeMap calltree visualisation. +For the rest, see the detailed "What's this?" help for +each part of KCachegrind and the quick starter on the +WWW page ( http://kcachegrind.sourceforge.net/cgi-bin/show.cgi ) + + + +Happy Profiling, + Josef Weidendorfer -- cgit v1.2.1
