scanmem & GameConqueror

Build Status Coverity Status

scanmem is a debugging utility designed to isolate the address of an arbitrary variable in an executing process. scanmem simply needs to be told the pid of the process and the value of the variable at several different times.

After several scans of the process, scanmem isolates the position of the variable and allows you to modify its value.


GameConqueror is a GUI front-end for scanmem, providing more features, such as:

  • Flexible syntax for searching
  • Easier and multiple variable locking
  • Better process finder
  • Memory browser/editor

See gui/ for more details.


scanmem requires libreadline to read commands interactively, and /proc must be mounted. GameConqueror requirements are documented in gui/


To read documentation:

  • man scanmem
  • man gameconqueror
  • scanmem --help
  • enter help at the scanmem prompt
  • use the interactive help of GameConqueror

Build Requirements

The build requires autotools-dev, libtool, libreadline-dev, intltool, and python.

Build and Install

To generate files required for the build:


To build with GUI:

./configure --prefix=/usr --enable-gui && make
sudo make install

To build without GUI:

./configure --prefix=/usr && make
sudo make install

scanmem and GameConqueror use static paths to libscanmem. So executing ldconfig is not required. Consider setting --libdir=/usr/lib/scanmem or --libdir=/usr/lib64/scanmem to avoid that libscanmem is in a library search path.

Run ./configure --help for more details.

Android Build

You need a standalone toolchain of Android NDK (Advanced method) to build interactive capabilities for Android. For more information, run:

./ help
