Missing tk.h and tcl.h files when building VRip

I am trying to compile VRip in Ubuntu 10.04, using the site http://graphics.stanford.edu/software/vrip/guide/ as a guide. It relies on installation of Tcl and Tk -- I have acquired the latest versions of these from the synaptic package manager.

When I write "make depend", I get the error:

In file included from vripInit.cc:30: vripInit.h:22:17: error: tcl.h: No such file or directory vripMain.cc:22:16: error: tk.h: No such file or directory In file included from vripMain.cc:28: vripInit.h:22:17: error: tcl.h: No such file or directory In file included from vripMiscCmds.cc:29: vripMiscCmds.h:22:17: error: tcl.h: No such file or directory In file included from vripFillCmds.cc:29: vripFillCmds.h:22:17: error: tcl.h: No such file or directory In file included from vripFileCmds.cc:29: vripFileCmds.h:22:17: error: tcl.h: No such file or directory In file included from vripGridCmds.cc:29: vripGridCmds.h:22:17: error: tcl.h: No such file or directory In file included from vripRangeCmds.cc:36: vripRangeCmds.h:21:17: error: tcl.h: No such file or directory In file included from vripGUICmds.cc:37: vripGUICmds.h:22:17: error: tcl.h: No such file or directory vripGUICmds.cc:43:16: error: tk.h: No such file or directory In file included from vripPlyCmds.cc:32: vripPlyCmds.h:22:17: error: tcl.h: No such file or directory rm makedep.bak

It seems to be looking for header files and not finding them. But I'm not sure where to tell it to look. Could anyone with more experience help out? I've spent a good couple of hours trying to figure this out without any success... :S

Thanks, LPlates

Install tcl-dev package using apt or synaptic; tcl contains the runtime, while tcl-devel contains header and development files. Do the same with tk-dev
