The xxgdb package comes with xxgdbiowin not compiled. I installed the source with rpm -ih xxgdb-1.12-10.src.rpm and then rpm -bc xxgdb.spec I noticed that the Imakefile already has DEFGDB = -DGDB -DCREATE_IO_WINDOW -g so I said: make xxgdbiowin I made sure all ather copies of xxgdbiowin were removed and in /usr/src/redhat/BUILD/xxgdb-1.12 said ./xxgdb xxgdb If I then say to xxgdb iowin (with . in my path). A window is popped up, but xxgdb then hangs. iowin is important for debugging ncurses programs. It was working with redhat 5.1.
The experiment I described did actually show a correctly working IO window, but after I installed the programmes I could not get it to work again. I will reinstall redhat 6 and retry.
workaround: xxgdbiowin will sometimes leave a special file in /tmp: srwxrwxr-x 1 jc jc 0 Oct 20 14:35 iowindowtty Note the first char of that long listing. Removing the file seems to let me run iowin again.
The work around seems to be adequate, as debugging ncurses with xxgdb hardly seems to have a critically important impact. Please reopen if you disagree.
