Terminal Emulation Issue under CentOS 7 - Hack Fix

[Nivethan T]

An FYI, unfortunately I don't know enough about C to tell you why but I hacked a solution in place to get terminal emulation working in CentOS 7.

Adding this line resolves the issue of "Unrecognised terminal name" when you do a "TERM LINUX".

gplsrc/qmtermlb.c:189

```

sprintf(filename + strlen(filename), "%c%c%c%s", DS, tname[0], DS, tname);

strcpy(filename,"/usr/qmsys/terminfo/l/linux");

```

The sprintf seems to be just the directory rather than a specific file and so the magic number check further down fails.

Is this anything to do with the current glitch in makefile and terminfo?
Wouldn't surprise me ...

Check that the terminfo directory exists, and that the permissions on it
are correct ...

Cheers,

Running the modified Makefile and bash script that I posted seems to fix all the install problems.  Just remember to run the bash script using sudo.

Ah, I didn't realize the Makefile fix was for 32bit as well. I thought it was just for 64bit. I'll take a look.

The terminfo directory does exist and from what I can tell the permissions look healthy. I did try running it as qmsys and had the same error about unrecognized terminal. 

This issue first cropped up in 2020 and specifically for CentOS 7 according to the changelog so it may be unrelated to the terminfo work you're working on.

Thanks

If it first appeared in 2020 then it won't be down to me ... iirc my
blunder was to reset the permissions inside the terminfo directory, so
that the linux (amongst all the rest) file was unreadable :-)

Something to do with muddling the user who compiled everything, with
root who copied everything, with qmsys who needed access ...
