In the past I used the Bless Hex Editor and found it to be very satisfactory for my needs and very reliable. I haven’t used it for a while but needed to view some files in hex and tried it again. It keeps crashing out every so often with an error like:

Is this a known bug that has crept in?
No idea, have never used this tool you mention. But if you urgently need a hex editor: antiX comes whith mc preinstalled, which includes a hex editor you can use out of the box without installing anything additionally. (highlight the file in mc, then press F3 (view file) → F4 (toggle between ascii/hex) → F2 (toggle view/edit mode), in this order.
Btw, how, from what repo or package and on what exact antiX version (sysvinit, runit, 32bit, 64bit, full, base, core…) did you install the tool? It looks like the system libraries it has been built against don’t match what your system runs on.
Windows is like a submarine. Open a window and serious problems will start.
Midnight Commander doesn’t seem to do the same thing as Bless. I want to view the contents of the file. Following your instructions in mc gives me a HEX/ascii dump of the file details, not the contents. If I press F4 directly it takes me to an edit screen of the file content but only in ascii.
This computer is still on antiX 22 (64 bit full install) with sysvinit. I installed Bless from the standard repos which haven’t been changed since the antiX installation.
So, the dependencies in the package are now broken then…?
It looks as if I will have to go on the hunt for a new hex editor.
I want to view the contents of the file. Following your instructions in mc gives me a HEX/ascii dump of the file details, not the contents.
For me the mc hexeditor works flawlessly. You must have done something differently. See screenshot, how it is expected to look. This is actually the file content which you can edit directly, not other details. On the left side the byte position is displayed, in the middle field the editable hex values, and in the right column an ascii representation, in which the current byte from the hex field is also highlighted. It has worked that way already in the old days of norton commander (nc) under dos, from which mc is clearly inspired.
I installed Bless from the standard repos
In this case you should possibly file a bug report to the package maintainers at debian.
$ apt-cache show bless Package: bless Version: 0.6.3-1 … Maintainer: Debian CLI Applications Team <pkg-cli-apps-team@lists.alioth.debian.org> …Unfortunately I don’t have any antiX 21/22 system running any longer, so I can’t check out. Maybe somebody else?

I’m pretty sure bless had no maintainer for Debian, which is why it was dropped from Debian 13, so that’s quite possible.
When I tried bless on antix-23 some time back, I had it crash a couple times, though not frequently. It also seemed to use a lot of memory for what it did, which may or may not also have been a bug.

I don’t understand what you’re trying to describe about midnight commander’s hex view/edit ability. What do you mean exactly by “file details” vs file contents? Maybe post a screenshot since it’s not very clear.
When you first open a file in mc’s viewer, you should see the file’s contents displayed as text (even if it’s a binary), then pressing F4 should switch to a traditional hex editor view with the file’s contents as hex values on the left and the contents as ASCII on the right, and with the addresses as a column on the far left. This is the default view of bless, too, as it is for most hex editors. At this point in mc viewer, you still shouldn’t be able to edit the file until pressing F2, after which you can use Tab to switch back and forth between ASCII editing and direct hex editing.
Since your description does’t seem to match that at all, to be sure you’re actually using mc’s built in viewer (I believe what F3 does in mc is configurable), you can open a file directly from the commandline without going through the mc file manager:
mcview /path/to/fileIn the end, I didn’t like the minor rigamarole of having to press F4 and then F2 to begin hex editing in mc and all the other GUI hex editors I tried from the Debian repos seemed even worse than bless, so I decided to just go with hexcurse as my hex editor. It’s very barebones, but can do what I need. Plus it has an awesome name.

OK. I think the complication is that I was trying to edit a zip file. When I try to view the contents in mc it opens the archive and lists the items in the archive. If I switch to HEX, it just converts that list from ascii to HEX – not all that useful in this specific case. I want to see a raw binary/HEX dump of the zip file. So, I think a dedicated HEX editor would be better for me.
It seems then that Bless has passed it’s sell by date. I’m checking out GHex and wxHexEditor to start off with as they seem to be at different ends of the spectrum.
Thank you both very much for the additional insights.

mc is pretty powerful. Press F8 simply to toggle between raw content and parsed index view (see screenshot, this is a zip file.)

Bless Hex Editor
* Removed from Debian indeed; https://tracker.debian.org/pkg/bless
* Git repository indicates stalled (or completed?) development; https://github.com/afrantzis/bless
* This Git issue discussions suggests few alternatives.My guess is that you have upgraded your antiX install and Bless survived but silently expecting different versions of libraries, hence the failures.
OK. More useful information!
I’ll not give up on mc just yet and based on sybok’s link I’ll add rehex to my list.
