Software Download


A prebuilt version of HistTool for WIN32 is available in the EPICS Win32 Extensions distribution.


The following tar files contain source code only (no binaries), and were compressed using gnuzip.

Required Software

Since histtool uses header files and/or libraries from the caObject2 extension, caObject2 is included in the histtool tar file and must be built first.

HistTool requires that the Motif and X11 header files and libraries be available and that the X11 and MOTIF settings in CONFIG_SITE.<host_arch> be set correctly. HistTool also uses the caObject2 extension, available from the Extensions download area.
