It can detect two common programming bugs: +software that overruns or underruns the boundaries of a malloc() memory +allocation, and software that touches a memory allocation that has been +released by free(). + +Unlike other malloc() debuggers, Electric Fence will detect read accesses +as well as writes, and it will stop and pinpoint the exact instruction +that causes an error. It is not as thorough as Purify, however. + +In order to debug a program it needs to be linked with Electric Fence's +library or dynamic linking needs to be used; README.Debian explains that +in detail. + +In addition to the static library (libefence.a), this package also +contains a shared library of electric fence (libefence.so). Thus, you +don't need to recompile your programs any more, all you need to do is: + +LD_PRELOAD=libefence.so ./your-buggy-program + +and libefence's malloc will be used. + +If you're using c++, and you and want to statically link your c++ +programs, you shouldn't use g++ to link libefence.a, but rather: + gcc -o myprog myprog.o -lstdc++ -lg++ -lefence +(if you use g++, the order is different, and efence's malloc doesn't +get used) + +Be sure to read the `libefence` manpage which describes how to set +various environment variables which alter lebefence's behavior diff --git a/libraries/electric-fence/electric-fence.SlackBuild b/libraries/electric-fence/electric-fence.SlackBuild new file mode 100644 index 000000000000..ab8f8f6727ca --- /dev/null +++ b/libraries/electric-fence/electric-fence.SlackBuild @@ -0,0 +1,110 @@ +#!/bin/sh + +# Slackware build script for Electric Fence + +# Copyright 2009-2010 Sean Donner (sean.donner@gmail.com) +# All rights reserved. +# +# Redistribution and use of this script, with or without modification, is +# permitted provided that the following conditions are met: +# +# 1.
