Has anyone else used the 'lharc' program recently submitted to c.s.misc?
I successfully compiled the code and was quite happy with the program (nice
compression ratio :-) however there seems to be a bug (or maybe I've missed
something obvious). When a file with any kind of extension (or in fact any
character in the name *other* than the basic alphanumeric set) is added to
the archive the "." (or whatever else) is (apparently) removed. Unfortunately
I have been unable to then retrieve the file from the archive. Kind of
annoying if you know what I mean :-)
Has anyone else noticed this problem, and better still, got a solution?!
The program works fine for straight filenames without extensions etc, but
that's all. I know one solution would be to rename all files that are
archived to remove the "."'s but that would be a pain...
Any help from anyone out there would be appreciated (oh, an English version of
the doc file would be nice too, if anyone should happen to have translated it!)
Thanks in advance,
John

Kind of > annoying if you know what I mean :-) > In a function which writes header (write_header ?) there is a call to toupper() which is not guarded by "if (islower(c)) {...". This may or may not make your life hard depending on how your toupper behaves. If you are using 'lharc' only for storing and retirieving files on Un*x, and not for exchanging with other, non-case-sensitive operating systems, you want probably undefine macro STRICT. Otherwise names of all unpacked files will come in lowercase only. As a side effect this will solve also the problem above as an offending 'toupper()' call will be not executed.

I could compile lharc.c with -O and use -O4 on lzhuf.c lhio.c . Using -O2,3,4 on lharc.c always gets a core dump from executing lharc. I love the compression ratio, but - I get core dumps when I do lharc c arcname directoryname what I have to do is: lharc c arcname directoryname/* which works just fine, except in one caes where directoryname/* was all directories, which also dumped core, forcing me to do: > foreach direct (installed/*) ? lharc a installed.lzh $direct/* ? end which also worked fine. Does anyone know how to get lharc to handle directory names without barfing ? thanx - Harry Langenbacher 818-354-9513 harry%neuron1@jpl-mil.jpl.nasa.gov harry@neuron1.jpl.nasa.gov 128.149.12.7
