The problem appears to be with the uuencode portion, because a file
encoded on a different system will uudecode correctly with the source
supplied.
If you compare a file encoded with the source code, against the same
file encoded on a Unix system, although the files are the same size,
each line on the Unix encoded file starts with a 'M' (or possibly the
'M' is after the newline on the previous. This does not appear with the
source code version.
Also when an attempt is made to decode a file uuencoded with the source
code version on a Unix system, the error "No end line" appears.
Excuse me for not being able to offer a solution, but this information
might help those more capable than myself.....

It already does this - is there a known problem with `fopen'?
Do I need to use
`open' instead?
4 lines matching "open" in buffer uudecode.c.
9: FILE *out, *in = fopen(fname, "rb");
11: fprintf(stderr,"Impossible to open %s\n",fname);
33: out = fopen(outname, "wb");
35: fprintf(stderr,"Impossible to open %s\n",outname);
1 line matching "open" in buffer uuencode.c.
10: if ((in = fopen(nom, "rb")) == NULL)

This is due to a bug on this line:
outbuf[idx++] = ENC(ch); # ch is not active at this time
which I changed to:
outbuf[idx++] = ENC(n); # n is the number of chars read
I'll send my version to John.

All,
The source code that was submitted uses an uninitialized variable and it
will generate garbage on some compilers.
See:
------------------------------------------------------cut here:
uuencode.c
#include <stdio.h>
#define ENC(c) ((c) ? ((c) & 077) + ' ': '`')
static int uuencode(char *nom) /* nom means 'name' in french :-) */
{
int ch, n, idx;
/* ^^
** Declaration */
register char *p;
char buf[80], outbuf[250];
FILE *in;
if ((in = fopen(nom, "rb")) == NULL)
return 1; /* please add some error checking/reporting */
printf("begin 0666 %s\n",nom);/* note: no attempt to fake any
permissions
*/
while ((n = fread(buf, 1, 45, in)) != 0) {
idx = 0;
outbuf[idx++] = ENC(ch);
/* ^^ first use.
Where is first initialization? */
for (p = buf; n > 0; n -= 3, p += 3) {
ch = *p >> 2;
ch = ENC(ch);
outbuf[idx++] = ch;
ch = ((*p << 4) & 060) | ((p[1] >> 4) & 017);
ch = ENC(ch);
outbuf[idx++] = ch;
ch = ((p[1] << 2) & 074) | ((p[2] >> 6) & 03);
ch = ENC(ch);
outbuf[idx++] = ch;
ch = p[2] & 077;
ch = ENC(ch);
outbuf[idx++] = ch;
}
outbuf[idx++] = '\n';
outbuf[idx] = 0;
printf("%s", outbuf);
}
printf("%c\nend\n", ENC(0));
fclose(in);
return 0;

This source simply doesn't work for me - it generates all sorts of
different
characters at the beginning of encoded lines, rather than the "M" that I
see
with most uuencoders.
I finally pulled over the sharutils-4.2 source, got that to build under
NT and
then carefully enabled (or disabled) the binary flag on the fopen calls.
It
now seems to work fine - without mucking with mounts or using bash (I
prefer
zsh).
Thanks for all the ideas...

I'm not sure, but I'll bet that you have to sligthly change the
uudecode source code to ensure that the open of the output file is done
in binary mode : open(... O_BINARY) or fopen(..., "wb")). Your problem
is most surely this infamous text!=binary feature :-( of Losedows...

I think uudecode should open its input in text rather than binary mode.

The input of uudecode *is* text, isn't it. I think the read mode should
be "r".

Those are part of the gnu sharutils package, and they have worked fine for me
when built normally under cygwin. I have had some difficulties with more
complicated usage of sharutils, however.

This is the AhHa!! Try `SET CYGWIN=binmode' before starting bash.
If this fixes the problem then the program needs to change the mode of
the stdout so that it is also binary. Note you probably should change
the stdin as well.

Oh yes but all opens are done in binary mode.. What I imply is that
opens of binary files (input for uuencode and output for uudecode) must
use binary mode; however opens of text files (output of uuencode and
input of uudecode) should be in text mode, and anyway most surely the
output of uuencode is in text mode, as this is simply stdout, that all C
run-times assume (unless special settings in the environment or your
program) that stdin, stdout and stderr should be opened in text mode...
What properly happens is that at some point uudecode, which read text in
binary mode, get a raw ^M at end of line, and then either go wild or
just stop...

Don't know, what you mean by reliable, but you can get the
sharutils-4.2c package, which contains uuencode/uudecode among other
utilities
- on ftp.franken.de
- in /pub/win32/develop/gnuwin32/cygwin32/porters/Hirmke_Michael/B20

These just don't work at all:
$ cp c:/WINNT/NOTEPAD.EXE n.exe
$ ./n.exe # works fine!
$ uuencode n.exe n.exe > n.uu
$ rm n.exe
$ ls n.*
n.uu
$ uudecode n.uu

These also don't work (see below).
This doesn't look like a "mount" problem? The cygwin FAQ states about mount:
"The '-b' option to mount mounts the mountpoint in binary mode where text and
binary files are treated equivalently. This should only be necessary for badly
ported Unix programs where binary flags are missing from open calls."
... and your code does open the files in binary mode, so shouldn't it work
regardless of mount?
It even seems to fail when I do mount a directory in binary mode...
If nobody has a solution, I guess I'll try debugging it when I get time.

Oddly, if I use the combination of the sharutils uuencode.exe and the
uudecode.exe that I compiled from the source posted here, it works.
Other combinations don't seem to work...
I've also hacked the uudecode source to read from stdin when given no args, so
I can use uudecode.exe with Emacs' call-process-region. At last uuencoded
attachments from Outlook can be quickly decoded from pGnus!

This source simply doesn't work for me - it generates all sorts of different
characters at the beginning of encoded lines, rather than the "M" that I see
with most uuencoders.
I finally pulled over the sharutils-4.2 source, got that to build under NT and
then carefully enabled (or disabled) the binary flag on the fopen calls. It
now seems to work fine - without mucking with mounts or using bash (I prefer
zsh).
Thanks for all the ideas...

This has taken enough bandwidth that we might at least understand what
happened.
As stated in their README, the shareutils from ftp.franken.de require
binary mount. On a text mounted system the uuencode INPUT file gets
truncated at ^Z.
Ideally uuencode should binary open its input file AND setmode stdin to
binary (for use with cygwin shells, other shells always open stdin binary).
Similarly the output of uudecode should be binary.
It doesn't matter if the output of uuencode and the input of uudecode are
text or binary. Those programs encode the line length, usually taking in 45
characters at a time (they have to, to survive inclusion in e-mails).
uuencoded lines start with M because M is the 45th printable character
(above " "). Those 45 characters are expanded to 45 * 8/6 = 60 characters
per line, plus the length.
The uuencode.c program contributed in
http://www.cygnus.com/ml/gnu-win32/1999-Jan/0493.html has a bug: the first
ENC(ch) should have been ENC(n). That's why the uuencoded lines did not
start with M.
There is also a bug in uudecode.c
if (!strncmp(buf, "end\r\n", 5))
will fail when the file ends with "end\n". The bug is not exposed because
the program normally terminates at the next to last line, which has zero
length.

For decode only, you might try uu.com from:
< http://www.walbeehm.com/mrcode.html >.
(That was: http://www.walbeehm.com/mrcode.html ).

Try sharutils-4.2 from http://www.gnu.org/software/software.html
It compiles out of the box.
