Now the problems seem desappeared. In any case, I will consider your
suggestion.


Many thanks,

Perhaps if you would submit a patch to newlib, something may happen.


Telling me what newlib is would greatly help in this regard :-)


Newlib is the library that Cygwin uses for some standard functions (math
and otherwise).

(The only way to interpret this question is "what is the connection
between newlib and Cygwin", as a quick Google would have pointed you to
the newlib webpage).


Yes, I was not precise.  I was unsure about the relationship between 
Cygwin and newlib.



I understand that adding llrint to Cygwin is probably not hard at all
for somebody familiar with Cygwin.  However, I am not such a person and
I don't even have a Windows environment around to test any modifications
I might make.

We are about to make an MPlayer release and unfortunately it will not
compile on Cygwin due to the missing llrint.  I would appreciate to know
if this is going to get addressed so that I can put an appropriate
comment in the release notes.


What's wrong with adding llrint to your code (perhaps with a #define,
i.e.,

#define llrint my_llrint
typeof(llrint) my_llrint(...) { ... }

)?


It is ugly and it is a workaround for a problem that should be solved 
outside of FFmpeg.  Should every project using llrint add that 
workaround?  No, Cygwin should be fixed.

What part of portable programming don't you get?  On platforms where
something is lacking, a portable program will use replacement functions to
make up for the platform limitations (autoconf is particularly helpful in
determining whether a platform has limitations so the replacement is not
used on platforms with more features, and gnulib is a good supply of a lot
of replacement functions).

And what part of open source programming don't you get?  If it bugs you,
write and submit a patch, so that cygwin WILL have llrint.  Cygwin won't
have it until someone takes the time to write it.

Cygwin uses newlib as-is for most such functionality.  So, patching
newlib to include llrint would automatically make Cygwin support it.

Also, newlib builds on Linux just as well as it does on Windows...

Fair enough.  I agree that it's ugly, but ultimately it's your call --
whether you want your project to compile on Cygwin or whether you want to
require the feature that's missing and accept that Cygwin compilation will
be broken for a while.

llrint is required, so I guess Cygwin compilation will indeed be broken 
for a while.  We don't add OS-specific workarounds to FFmpeg.

Workarounds for broken variants of the many multimedia formats we

I call shenanigans.  The libavcodec directory has entirely separate 
subdirs for different processors -- platform specificity is BUILT IN to 
the ffmpeg source tree.  Second, common.h contains compiler-specific 
workarounds:


#ifndef av_always_inline
#if defined(__GNUC__) && (__GNUC__ > 3 || __GNUC__ == 3 && 
__GNUC_MINOR__ > 0)

#define av_always_inline __attribute__((always_inline)) inline
#else
#define av_always_inline inline
#endif
#endif

to account for gcc-specific behavior. That file ALSO contains a 
half-dozen implementations of read_time depending on which 
microprocessor architecture is in use.


internal.h has this:

// Use rip-relative addressing if compiling PIC code on x86-64.
#if defined(__MINGW32__) || defined(__CYGWIN__) || \
defined(__OS2__) || (defined (__OpenBSD__) && !defined(__ELF__))
#if defined(ARCH_X86_64) && defined(PIC)
#define MANGLE(a) "_" #a"(%%rip)"
#else
#define MANGLE(a) "_" #a
#endif
#else
#if defined(ARCH_X86_64) && defined(PIC)
#define MANGLE(a) #a"(%%rip)"
#elif defined(__APPLE__)
#define MANGLE(a) "_" #a
#else
#define MANGLE(a) #a
#endif
#endif

which looks pretty darn OS-specific to me.  (__CYGWIN__? __MINGW32__? 
__OS2__?)


Oh, and lookee here, in the same file:

#ifndef HAVE_LRINTF
/* XXX: add ISOC specific test to avoid specific BSD testing. */
/* better than nothing implementation. */
/* btw, rintf() is existing on fbsd too -- alex */
static av_always_inline long int lrintf(float x)
{
return (int)(rint(x));
}
#endif /* HAVE_LRINTF */

a replacement function lrintf() that is activated only when a configure 
test determines that lrintf doesn't exist and therefore neglects to 
define HAVE_LRINTF


So, we have:
  architecture-specific workarounds
  compiler-specific workarounds
  OS-specific workarounds
  AND capability-specific (!HAVE_FOO) workarounds

All god's chillins gots workaround code. "We don't add OS-specific 
workarounds", indeed...

Bug In Cygwin For Vista Setup Postinstall post-textmf.sh

[Thomas Dineen]

Gentle People:

  I have found a bug actually a hang condition when I attempt to
run Setup for Cygwin on my Toshiba Satellite with MS Vista
with all current MS Windows updates installed.

  The hang occurs in the "Running" section of Setup on the file:
/etc/postinstall/post-texmf.sh

   From what I can tell I am running the current version of Cygwin
Version 1.5.24-2.

  This hang prevents Setup from finishing.

   What is the best way to fix this?

   BTW: I did install successfully on my win2k machine.
Great Software once it is installed.

Thanks for the help.

Problems with freshclam

[Angelo Graziosi]

Using freshclam.exe (from clamav-0.91.2-1), now gives these errors:

$ fresclam.exe
ERROR: Please edit the example config file /etc/freshclam.conf.
ERROR: Please edit the example config file /etc/clamd.conf.
ERROR: Can't parse the config file /etc/clamd.conf

It worked fine until a few days ago.


In /etc the file are:

$ ls -lrt /etc/*clam*

-rwxrwx---+ 1 user Administrators 3620 Sep 27 22:46 /etc/freshclam.conf
-rwxrwx---+ 1 user Administrators 9174 Sep 30 01:19 /etc/clamd.conf


Any idea?


TIA,

  Angelo.

using a USB flash mem device

[Tom Hall]

I got this nice little Sandisk "sansa express" MP3 player that plugs into the
USB port on my XP machine.

Unlike other USB devices I've used, Windows doesn't give this thing a drive
letter, but does something else; it shows up on the "explorer" window and kind
of acts like a drive there, but it doesn't show up in the /cygdrive directory.

Is there a way I access this with cygwin as if it were a drive ?

Re: Problems with freshclam

[d.henman]

I have the same version but have not encountered the problem you mention.

I have:
ls -l /etc/*clam*
-rwx-- 1 djh Users 9293 Jun 28 09:22 /etc/clamd.conf
-rwx-- 1 djh Users 3619 Jun 28 09:13 /etc/freshclam.conf

freshclam.conf is probably the same as yours, but our clamd.conf file sizes
are 119 bytes different.  I don't recall ever doing anything to it

Maybe try download a new freshclam.conf file.

Edit the file and comment out the "Example" as the instructions above it say,
then add your favorite options... closest db server.

When did you install version 0.91.2?  The post-installer probably erased your
original configuration, which is a bug, just make sure before reporting it.
