The thing is, libarchive needs to be compiled with zlib in order to support
.tar.gz files. While it's not *that* difficult, it's still extra work that
could be easily avoided by shipping two additional files ( libarchive
.dll[for Windows] and .so[for Linux] ). So, wouldn't it be better to ship
those extra files and save everyone from manually compiling libarchive?
That should be okay. How do you retrieve the home directory?
Using Qt's QDir::homePath().
http://qt-project.org/doc/qt-4.8/qdir.html#homePath
"Error: Failed to open 'MatrixMarket/gearbox.tar.gz'Error: INTERNAL ERROR:
> Function 'archive_read_next_header' invoked with archive structure in state
> 'new', should be in state 'header/data'Detected files in archive:"
Ah, I forgot to remove the libarchive testing. It's attempting to extract a
file that doesn't exist. I should probably implement something to prevent
crashing when doing just that. The interesting here is that it if your
libarchive wasn't compile with zlib, it would still crash even if you had
the file.
Unfortunately I cannot comment on the GUI with this, as it never pops up.
I haven't done much with the GUI. Been focused on MatrixMarket and file
extraction. I only added system info boxes on the homescreen.
2 MB is nothing ;-)

Roger that. Integrating it into the executable.

Perhaps I could re-route opening of external links to be forwarded to the
system's default web-browser. Links used to navigate the MatrixMarket would
use our static pages, while any external links would be opened in the
system's web-browser. How does that sound?
As for the grouping: well we don't really *need* it, but it would be a nice
thing to have...

I guess so.

I don't quite follow you on this one. Are you thinking we could collect
all the detailed info for each of the 2700 matrices?
The details I was referring to are the ones you see when you click on a
matrix. For example:
http://www.cise.ufl.edu/research/sparse/matrices/AG-Monien/3elt.html
As you can see, there are lots of data about it that isn't shown in the
matrix list. I assume this data is important, and should be viewable from
within our MatrixMarket. My concern was that these detailed pages contain
links to external sites, enabling users to go outside our static html
pages.
Different thought:
Instead of all these complicated HTML transformations, isn't it simpler to

I think this is where all problems come from. It all basically comes down
to this:
-is it enough to provide only the most relevant info for each matrix (like
the info shown when listing matrices:
Group/Nameiddownload# rows# colsnonzerostypesymspd?-or, do we need to
provide ALL matrix info, including the detailed info shown when examining
individual matrices?
If we just need the basic stuff, then all is fine. I'll make a static list
containing the basic info of each matrix, and use it to generate our static
MatrixMarket pages.
Providing detailed info, however, is not that easy since there's a lot of
it.
So which one is it?
