SPEC: http://home.bawue.de/~ixs/libtxc_dxtn/libtxc_dxtn.spec
Description:
S3 Texture Compression (S3TC) (sometimes also called DXTn or DXTC) is a group
of related lossy image compression algorithms originally developed by S3
Graphics, Ltd.
Currently, s3tc is supported by libtxc_dxtn on all graphic cards which use the
radeon, r200, i830 and i915 driver. Other DRI drivers are not supported, even
if the hardware could do it, at least not until someone writes the code for it.
Not eligible for fedora:
S3TC is patented.
rpmlint:
[andreas@workstation result]$ rpmlint -v *.rpm

libtxc_dxtn.src: I: checking
libtxc_dxtn-debuginfo.i586: I: checking
3 packages and 0 specfiles checked; 0 errors, 1 warnings.
no-soname is a shame, but I didn't want to meddle with upstream code as the
version number is horrible anyway.

I'd suggest using 070518 as Version rather than 0.0.0.070518, for 2 reasons:
1. That's really the version upstream uses. They don't use any 0.0.0. And it
doesn't look like they're planning to use another versioning scheme any time
soon.
2. Fabrice Bellet (the rpmfind.net admin (not to be confused with Fabrice
Bellard, the QEMU guy)) has libtxc_dxtn packages with Version set to 050908, so
0.0.0.x versioning breaks upgrade paths from that repo.

As for the "no-soname" warning, it can be ignored, this is a plugin, it's
designed to be dlopened only, never linked, so it doesn't make sense to version
it.

1. That's really the version upstream uses. They don't use any 0.0.0. And it

Interestingly the source code itself contains a 0.1 version identifier.
Thus the 0.0.0.070518 version just to be able to raise it if the need arrises
without using an epoch. (even if epoch is not as bad as some people claim it to
be...)
2. Fabrice Bellet (the rpmfind.net admin (not to be confused with
Fabrice
Bellard, the QEMU guy)) has libtxc_dxtn packages with Version set to 050908, so
0.0.0.x versioning breaks upgrade paths from that repo.
Yeah. That is a more acceptable reason than 1.
Thus I'd see on problem to possible change the version id, but this shouldn't
prevent a review and could be changed during import anyway.

I concur with that. The current user of this library is Mesa. It could
potentially be the case that another piece of software is linking directly
against the library, but I've not known of any such program.
If this should be the case, one could always consider hacking in a soname
later.

I've also made one:

Starting from your spec:
You aren't using our $RPM_OPT_FLAGS
Harcoding mesa-liBGL should be avoided. (despite it is clear that this is aimed
to be used with mesa).
Of course, there is a need to have runtime tests done, specially to see if the
features still works.
AFAIR, this kind of library only makes sense when the related application was
wrongly coded, because most hardware support s3tc compress in hardware despite
this is disabled by default (can be enabled with driconf). This library
implement this feature in software as a fallback for wrongly codec application.
So, we need names for such wrongly coded application and eventually a
bugreport.

Huh? What the hardware does is texture *de*compression. The point of texture
compression is that you compress the textures before uploading them to the
hardware to save bus bandwidth.
The only way you don't need S3TC compression support in the driver is to store
the already compressed textures in your program (in addition to the
uncompressed ones, as not all hardware supports S3TC). Very few apps do that.

Right. Fixed <http://home.bawue.de/~ixs/libtxc_dxtn/libtxc_dxtn.spec>

Why then?

Yes, it does.

You're wrong. Please read
<http://homepage.hispeed.ch/rscheidegger/dri_experimental/s3tc_index.html>
carefully, specifically the "How to install" part.

You're wrong. Please read
<http://homepage.hispeed.ch/rscheidegger/dri_experimental/s3tc_index.html>
carefully, specifically the "How to install" part.
I've read this
page one year ago, and I seem to have a good memory, quoting:
"So, in principle, you might not even need the external library..."
I can expect that installing this will enable opengl functions likes
GL_S3_s3tc, GL_EXT_texture_compression_s3tc (If it actually work). Because
thoses implementation can possibly be fully compliant to the standard. I would
like to evaluate the difference between having this library and using
force_s3tc_enable=true". At least, testing with quake3, GL_S3_s3tc remained
ignored in both cases with my radeon x600se.
So despite the page list some possibly supported hardware( where my own
hardware is not), I wonder if this code is still supported with the current
mesa version, since the top of the page says:
"Note: this page is no longer updated and the code no longer maintained."
Which app have you tested to evaluate if the library works ?

No answear, rejected for me because it has not proven usability.
