Title: Re: Hi, Ken, Try running it from a DOS console window, you might get some error output spewed into the console that you can use.  The usual thing in this case is that Insight is not correctly finding the Tcl code that it needs to run. Jim Hi, Cant get the GUI for insight to run. I downloaded the Insight 5.0 release and was finally able to build it (new to this stuff).  When trying to run "gdb.exe" it briefly opens then closes a dos window, the GUI never runs.  If I run with the "--nw" option, then the command line version opens up normally. I ran gdb within gdb and got the following output. (gdb) run Starting program: c:\gnu\insight-5.0\m68k-elf\gdb.exe 66600000:C:/GNU/INSIGHT-5.0/M68K-ELF/TIX4180.DLL 7fcb0000:C:/WINDOWS/SYSTEM/SHELL32.DLL bfe90000:C:/WINDOWS/SYSTEM/COMCTL32.DLL 70bd0000:C:/WINDOWS/SYSTEM/SHLWAPI.DLL 7fe10000:C:/WINDOWS/SYSTEM/COMDLG32.DLL 66300000:C:/GNU/INSIGHT-5.0/M68K-ELF/CYGTK80.DLL 66800000:C:/GNU/INSIGHT-5.0/M68K-ELF/CYGITK30.DLL bfe80000:C:/WINDOWS/SYSTEM/ADVAPI32.DLL bff20000:C:/WINDOWS/SYSTEM/GDI32.DLL bff50000:C:/WINDOWS/SYSTEM/USER32.DLL bff70000:C:/WINDOWS/SYSTEM/KERNEL32.DLL 61000000:C:/GNU/INSIGHT-5.0/M68K-ELF/CYGWIN1.DLL 66000000:C:/GNU/INSIGHT-5.0/M68K-ELF/CYGTCL80.DLL 66700000:C:/GNU/INSIGHT-5.0/M68K-ELF/CYGITCL30.DLL Program exited normally. (gdb) Any ideas on why the GUI is not running? Running and compiling on Win98.   --host=i586-pc-cygwin  --target=m68k-elf Thanks, Kenneth Moore
