You got a tgdb_wish for the IRIX operating system (release 5.2, SGI). tgdb_wish is an interpreter which is needed to execute tgdb's source code (tgdb is a graphical user interface for the gdb debugger). It contains the following Tcl/Tk packages and extensions: tcl7.3 tk3.6 tclX7.3a BLT1.3 TkSteal3.6c expect5.8 This package contains a version of the tgdb_wish with dynamically linked standard libs of the IRIX 5.2 system and statically linked versions of the Tcl/Tk libs and extensions. To run tgdb, get its source distribution from sunsite.unc.edu:/pub/Linux/devel/debuggers/tgdb-[version].src.tgz unpack it, and copy tgdb_wish and the tcllib directory into the tgdb-[version] directory (e.g. "rcp -r tgdb_wish tcllib ../tgdb-1.1"). Then proceed as written in tgdb's INSTALL file. Should you encounter problems with this tgdb_wish, please send Email to hammer@kirk.fmr.maschinenbau.th-darmstadt.de. Enjoy! Matthias Hammer
