mod_perl, feel free to contact me.
How about being a bit more "positive" when checking for perl? The
following patch tests whether the dll being built contains an object
called 'perl.o' (would we have to check $(OBJ_EXT)? I hope not -
perlld is cygwin and cygwin has '.o'):

I admit that I have not yet rebuilt perl with this perlld -
but mod_perl now takes the perlld step without being renamed.
This idea is good! I'll try s.th. along these lines.
P.S.: In the meantime I managed to compile mod_auth_kerb as well,
linking against /usr/bin/libhttpd as you recommended. So my mod_perl
deviation had its merits :-)
P.P.S.: In my "success story" about mod_perl I forgot to mention that
I had to run rebaseall to get the server running.
Try to use --enable-auto-image-base for linking, this should minimize
the need for rebasing.
P.P.P.S.: Ah, yes, and I had to re-install emacs because it got stuck
in an endless loop immediately after starting (consuming 100% CPU)
after the rebaseall.
I try to avoid using rebase and I don't use emacs, but I think if it is
a generic problem with emacs it is probably well known, maybe the
archives contain some discussion about this issue.

Updated MySQL patch file to version 4.1.13a (was: Re: Trouble making .so (undefined symbols))
Repost because the mail was too large with the attached patch, will send
on request, please send reply to this mail to my private address if you
want the patch file.
The patch is against MySQL 4.1.13a. If there are some hunks failing for
some Makefile.in or configure, just ignore it and run
`autoreconf -f -v -i` after applying it
( ---> only if applying this patch to later releases).
I'm using a script to build the server, usage:
put the script, the extracted patch file and the source tarball together
in one directory, run the script with option 'all' or run the several
steps manually:
./mysql-4.1.13a-1.sh prep
./mysql-4.1.13a-1.sh lnconf
./mysql-4.1.13a-1.sh conf
./mysql-4.1.13a-1.sh build
./mysql-4.1.13a-1.sh install
./mysql-4.1.13a-1.sh strip
./mysql-4.1.13a-1.sh pkg
./mysql-4.1.13a-1.sh spkg
./mysql-4.1.13a-1.sh finish
This results in three tarballs, one including patch, script and source
tarball, one including the runtime and one including import libraries
and headers. Docs are included in the runtime package.
One addition because I cannot run make test with this script:
$ diff -u mysql-4.1.13a/mysql-test/mysql-test-run.pl~

I don't know why registers are not dumped. Running it through gdb or

Adding a Sleep(1000); in the f() function before returning prevents from
the crash, so I guess f() returning fast triggers a race condition in
the pthread code.

Re: Migrating .emacs Configuration File to Newer Emacsen
Please avoid pointing at each other blaming for the fault, Emacs maintenance should be in cathedral mode instead of bazaar mode because it is an important infrastructure and deregulation and privatising infrastructures hasn't yielded the benefits promised, but worsened service and quality below former public maintenance which will make shareholder value go down rapidly in the not too far future. I am not sure whether I agree, but I think the main problem with Emacs maintenance is that I don't have enough time to spend on it.

ls doesn't read stdin. Instead, use xargs, which does read a list of
filenames on stdin and turns it into arguments, or else use find itself to
pass the filename on to ls:
find a -daystart -type f -mtime 7 -printf " %p" | xargs ls -l
find a -daystart -type f -mtime 7 | xargs ls -l
find a -daystart -type f -mtime 7 -exec ls -l {} \;
By the way, the first two have problems with spaces in filenames, and also
if there are no filenames found, so if you really want to use xargs, try:
find a -daystart -type f -mtype 7 -print0 | xargs -r0 ls -l
Or if you like ls -dils instead of ls -l:
find a -daystart -type f -mtime 7 -ls

This is not a cygwin-specific problem, but a general misunderstanding on
your part how find and ls work. Read up on their man or info pages.

I thought the following would produce "ls -l" output for the space-separated list of files selected by the "find" options, but instead I get an error message from "ls": $ find a -daystart -type f -mtime 7 -printf " %p"|ls -l - ls: -: No such file or directory The output from the "find" looks like this: $ find a -daystart -type f -mtime 7 -printf " %p" a/list.txt a/list_0002.txt I do not have an *ix system on which to test if this is a Cygwin coreutils problem or a misunderstanding by me of the operation of the "-" option. Can you please tell me if I am wrong about my use of the "-" option? cygcheck -svr output pasted below, unfortunately Yahoo mail doesn't seem to allow me to create an attachment to send. TIA for any help/RTFM/info you can provide.

The coreutils info page does list it as a common flag, but my interpretation of the language there is that it's only referring to programs that act as input/output filters, not as a general-purpose way of passing filename arguments. That's why xargs exists. You can get ls-like output from find without any other programs: find a -daystart -type f -mtime 7 -ls If you must use an external program, the usual way to take the output from find and send it as arguments is with xargs: find a -daystart -type f -mtime 7 | xargs ls -l Note that both this and your '-printf " %p"' method will not work for filenames that contain spaces or special characters. Therefore the superior way of doing this is: find a -daystart -type f -mtime 7 -print0 | xargs -0 ls -l > I do not have an *ix system on which to test if this > is a Cygwin coreutils problem or a misunderstanding by > me of the operation of the "-" option. Can you please > tell me if I am wrong about my use of the "-" option? It doesn't work under linux either. (It's the same coreutils code in either case.)

How to use xargs is a definite hole in my knowledge. I have read the xargs info a few times, but I don't think I have understood it yet. I will go back to it and try to get it this time. > You can get ls-like output from find without any > other programs: > > find a -daystart -type f -mtime 7 -ls > > If you must use an external program, the usual way > to take the output from find and send it as > arguments is with xargs: > > find a -daystart -type f -mtime 7 | xargs ls -l Yes, I saw that in the info for the find "-ls" option, but in this case I am going to eventually substitute another external program for "ls" to process the filenames in another way. xargs would seem to be the correct answer for that, as you noted. > Note that both this and your '-printf " %p"' method > will not work for filenames that contain spaces or > special characters. Therefore the superior way of > doing this is: > > find a -daystart -type f -mtime 7 -print0 | xargs -0 > ls -l Not a problem in this case, the filenames to be processed are space-less and without any special characters because of the program that creates them. Thanks anyway for the info, I will remember it. > It doesn't work under linux either. (It's the same > coreutils code in either case.) Understood. Many thanks for reducing my level of ignorance.

Re: Cygrunsrv -windows 2k service hangs with message "Stopping"
You have to find the cygrunsrv process associated with that service and kill it using Task Manager or whatever. I have not found a way of matching them up, so when I am having problems with one of my Cygwin services, I shut down all other Cygwin services so I don't kill the wrong one. -- lhicks at nc dot rr dot com -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/

True -- if it's confusing only to me, that's of little interest to the reader. Saying "it can be a bit confusing" would be more relevant (and also true, I'm afraid). Predisposing first-time users into thinking that installation is "confusing" is not, IMO, a really good idea. I'm sympathetic, and open to suggestions. I'd prefer something like "can be a little complicated depending on what you're trying to install". I think I can live with this as long as the sentence ends after the word "complicated." To me, the package selection process is counter-intuitive regardless of how much or how little I'm trying to install. I'm certainly not trying to denigrate Cygwin; I'm trying to solve a practical problem: how to get readers to install Cygwin, without giving up in the middle, so they can get to the next step (which happens to be running g++ and make). I also have to say something about why I'm going into such detail, rather than just saying "run the installation utility." As long as I have some plausible way to introduce the detailed installation instructions, without bending the truth too much, I'm happy. cgf Best Regards, Jonathan -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/

gcc 4.0 on cygwin
Continuing discussions regarding gcc 3.4 beg the question of when we are going to start work on gcc 4.0 for cygwin. Is there anything holding us back? As I understand it, Debian will skip over gcc 3.4 and move from 3.3 to 4.0 as its standard compiler for Etch. This gives me some confidence that gcc 4.0 is going to be very thoroughly vetted over the next 18 to 24 months. I wonder if the time we are spending on gcc 3.4 might be better spent on what will probably be a better tested and better performing compiler. No disrespect is intended for the massive amount of work already done on gcc 3.4. I just wonder if it isn't time to move on? -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
