After i packaged apache to be portable (used any where), I had the surprise to get 403 error on AliasMatch but not on regular Location resources.
Update: I found the fix. Check answer.
And so, here is my own response.
I check the error.log and saw the path of the aliasmatch was wrong ( what a scoop). But note this path is made using a variable. Actually, all the character / that we can expect have been removed.
I look to the origin of the variable but not at the beginning, because all URI based on Location was working. Amazing ! But , the fact is, Location directive seems to convert the ugly \ windows in / to work, but not the AliasMatch directive. I forget to tell that i launched Apache using command line httpd with option -D and ... an ugly windows path with \ and not /. So, i convert the path in a pretty unix path and all is back in order.
In dos command : SET APACHE_ROOT="%THE_WINDOWS_PATH:\=/%"

Beginner user on cURL. I'm really struggling with the path format used to upload a file through cURL.
curl -X POST https://XXXXXXXXX … -F file=#C:\Users\John\Downloads\test.csv
I keep getting the following error message "curl: (26) Failed to open/read local data from file/application"
Most of the examples provided start with file=#/home/, which is confusing as I don't have such directory to my understanding. Also, examples use "/" instead of "\". Why is it so?
Can anyone provide some feedback on how to properly write the path to a file?
Thanks!
Finally solved this! After some trials and errors, I figured out that the path's syntax should have used double backslash, so:
C:\\Users\\John\\Downloads\\test.csv
and not:
C:\Users\John\Downloads\test.csv
Honestly, I have never used this syntax before and don't understand why this is required. Your comments/input would certainly be appreciated.
(OS is Windows 7 Professional. jq is version 1.5.)
I've been using jq to automate prettifying some JSON files (with Python). It seems to me after some time trying to determine why it wasn't working that jq fails silently when working with a file path string that's length 28, or simply stops working if the file path string is length 29 or more.
E.g. on cmd (and it's worth pointing out that I made a kind of shortcut so that jq calls jq-win64.exe, and tested the latter directly as well, so that's not the source of the issue):
C:\jq>jq . 123456789012345678901234567
displays prettified content of the file;
C:\jq>jq . 1234567890123456789012345678
displays nothing; and
C:\jq>jq . 12345678901234567890123456789
causes a "jq-win64.exe has stopped working" window.
(I also tested this on JSON files within folders; the common point was that the input string be of length 28 or more including slashes to fail.)
Is this a bug? If it's not, what can I do to work around it Okay, I admit that was a stupid question, I can work around it by copying content into a temp file in the base folder, prettify it, and then save it back to wherever I want it to be. More on-point question: is this the best workaround available for me to take?
There was a Windows-specific bug in jq 1.5 (see e.g. https://github.com/stedolan/jq/issues/1094). It was fixed shortly after the release of jq 1.5.

CLISP's interface to PARI is configured with the configure.in containing AC_LIB_LINKFLAGS([pari]) from lib-link.m4.
The build process also requires the Makefile to know where the datadir of PARI is located. To this end, Makefile.in has
prefix = #LIBPARI_PREFIX#
DATADIR = #datadir#
and expects to find $(DATADIR)/pari/pari.desc (normally
/usr/share/pari/pari.desc or /usr/local/share/pari/pari.desc).
This seems to work on Mac OS X where PARI is installed by homebrew in /usr/local (and LIBPARI_PREFIX=/usr/local), but not on Ubuntu, where PARI is in /usr, and LIBPARI_PREFIX is empty.
How do I insert the location of the PARI's datadir into the Makefile?
PS. I also asked this on the autoconf mailing list.
PPS. In response to #BrunoHaible's suggestion, here is the meager attempt at debugging on Linux (where LIBPARI_PREFIX is empty).
$ bash -x configure 2>&1 | grep found_dir
+ found_dir=
+ eval ac_val=$found_dir
+ eval ac_val=$found_dir
You are trying to use $(prefix) in an unintended way. In an Autotools-based build system, the $(prefix) represents a prefix to the target installation location of the software you're building. By setting it in your Makefile.in, you are overriding the prefix that configure will try to assign. However, since you appear not to have any installation targets anyway, at least at that level, that's probably more an issue of poor form than a cause for malfunction.
How do I insert the location of the PARI's datadir into the Makefile?
I'd recommend computing or discovering the needed directory in your configure script, and exporting it to the generated Makefile via its own output variable. Let's take the second part first, since it's simple. In configure.in, having in some manner located the wanted data directory and assigned it to a variable
DATADIR=...
, you would make an output variable of that via the AC_SUBST macro:
AC_SUBST([DATADIR])
Since you are using only Autoconf, not Automake, you would then manually receive that into your Makefile by changing the assignment in your Makefile.in:
DATDIR = #DATADIR#
Now, as for locating the data directory in the first place, you have to know what you're trying to implement before you can implement it. From your question and followup comments, it seems to me that you want this:
Use a data directory explicitly specified by the user if there is one. Otherwise,
look for a data directory relative to the location of the shared library. If it's not found there then
(optional) look under the prefix specified to configure, or specifically in the specified datadir (both of which may come from the top-level configure). Finally, if it still has not been found then
look in some standard locations.
To create a configure option by which the user can specify a custom data directory, you would probably use the AC_ARG_WITH macro, maybe like this:
AC_ARG_WITH([pari-datadir], [AS_HELP_STRING([--with-pari-datadir],
[explicitly specifies the PARI data directory])],
[], [with_pari_datadir=''])
Thanks to #BrunoHaible, we see that although the Gnulib manual does not document it, the macro's internal documentation specifies that if AC_LIB_LINKFLAGS locates libpari then it will set LIBPARI_PREFIX to the library directory prefix. You find that that does work when the --with-libpari option is used to give it an alternative location to search, so I suggest working with that. You certainly can try to debug AC_LIB_LINKFLAGS to make it set LIBPARI_PREFIX in all cases in which the lib is found, but if you don't want to go to that effort then you can work around it (see below).
Although the default or specified installation prefix is accessible in configure as $prefix, I would suggest instead going to the specified $datadir. That is slightly tricky, however, because by default it refers to the prefix indirectly. Thus, you might do this:
eval "datadir_expanded=${datadir}"
Finally, you might hardcode a set of prefixes such as /usr and /usr/local.
Following on from all the foregoing, then, your configure.in might do something like this:
DATADIR=
for d in \
${with_pari_datadir} \
${LIBPARI_PREFIX:+${LIBPARI_PREFIX}/share/pari} \
${datadir_expanded}/pari \
/usr/local/share/pari \
/usr/share/pari
do
AS_IF([test -r "$[]d/pari.desc"], [DATADIR="$[]d"; break])
done
AS_IF([test x = "x$DATADIR"], [AC_MSG_ERROR(["Could not identify PARI data directory"])])
AC_SUBST([DATADIR])
Instead of guessing the location of datadir, why don't you ask PARI/GP where its datadir is located? Namely,
$ echo "default(datadir)" | gp -qf
"/usr/share/pari"
does the trick.
I am trying to copy the contents of a log file to another log file using this command:
type \\server\f$\Test path\Test.log >> \\server2\f$\Logs\Testpath\Test.log
This has always worked in the path, but recently I have changed the location (path) to Test.log. The path is slightly longer. I now get an error:
The system could not find the file specified
I have googled this statement and the common responses are: 1) check the filename exists, 2) check the filename is not corrupt 3) Check the server is online.
I have done all of this. Is there a restriction on the number of characters a path can have? If there is then is there a workaround?
UPDATE 12/07/2012 09:49 GMT
Adding quotes around the path seems to resolve the problem. Why does adding quotes resolve the problem?
The problem was that the source path had a space in it. Adding quotes around the path resolved the problem.
Type is to examine a file, not to copy.
Also, if server is an actual server and not a folder, then you should be using two slashes (\server\share)
Example:
copy \\server\f$\Sourcepath\Test.log \\server2\f$\Logs\Destpath\Test.log /y

Okay so here is what I want to do. I want to add a print option that prints whatever the user's document is to a PDF and adds some headers before sending it off to a device.
I guess my questions are: how do I add a virtual "printer" driver for the user that will launch the application I've been developing that will make the PDF (or make the PDF and launch my application with references to the newly generated PDF)? How do I interface with CUPS to generate the PDF? I'm not sure I'm being clear, so let me know if more information would be helpful.
I've worked through this printing with CUPS tutorial and seem to get everything set up okay, but the file never seems to appear in the appropriate temporary location. And if anyone is looking for a user-end PDF-printer, this cups-pdf-for-mac-os-x is one that works through the installer, however I have the same issue of no file appearing in the indicated directory when I download the source and follow the instructions in the readme. If anyone can get either of these to work on a mac through the terminal, please let me know step-by-step how you did it.
The way to go is this:
Set up a print queue with any driver you like. But I recommend to use a PostScript driver/PPD. (A PostScript PPD is one which does not contain any *cupsFilter: ... line.):
Initially, use the (educational) CUPS backend named 2dir. That one can be copied from this website: KDE Printing Developer Tools Wiki. Make sure when copying that you get the line endings right (Unix-like).
Commandline to set up the initial queue:
lpadmin \
-p pdfqueue \
-v 2dir:/tmp/pdfqueue \
-E \
-P /path/to/postscript-printer.ppd
The 2dir backend now will write all output to directory /tmp/pdfqueue/ and it will use a uniq name for each job. Each result should for now be a PostScript file. (with none of the modifications you want yet).
Locate the PPD used by this queue in /etc/cups/ppd/ (its name should be pdfqueue.ppd).
Add the following line (best, near the top of the PPD):
*cupsFilter: "application/pdf 0 -" (Make sure the *cupsFilter starts at the very beginning of the line.) This line tells cupsd to auto-setup a filtering chain that produces PDF and then call the last filter named '-' before it sends the file via a backend to a printer. That '-' filter is a special one: it does nothing, it is a passthrough filter.
Re-start the CUPS scheduler:sudo launchctl unload /System/Library/LaunchDaemons/org.cups.cupsd.plist
sudo launchctl load /System/Library/LaunchDaemons/org.cups.cupsd.plist
From now on your pdfqueue will cause each job printed to it to end up as PDF in /tmp/pdfqueue/*.pdf.
Study the 2dir backend script. It's simple Bash, and reasonably well commented.
Modify the 2dir in a way that adds your desired modifications to your PDF before saving on the result in /tmp/pdfqueue/*.pdf...
Update: Looks like I forgot 2 quotes in my originally prescribed *cupsFilter: ... line above. Sorry!
I really wish I could accept two answers because I don't think I could have done this without all of #Kurt Pfeifle 's help for Mac specifics and just understanding printer drivers and locations of files. But here's what I did:
Download the source code from codepoet cups-pdf-for-mac-os-x. (For non-macs, you can look at http://www.cups-pdf.de/) The readme is greatly detailed and if you read all of the instructions carefully, it will work, however I had a little trouble getting all the pieces, so I will outline exactly what I did in the hopes of saving someone else some trouble. For this, the directory with the source code is called "cups-pdfdownloaddir".
Compile cups-pdf.c contained in the src folder as the readme specifies:
gcc -09 -s -lcups -o cups-pdf cups-pdf.c
There may be a warning: ld: warning: option -s is obsolete and being ignored, but this posed no issue for me. Copy the binary into /usr/libexec/cups/backend. You will likely have to the sudo command, which will prompt you for your password. For example:
sudo cp /cups-pdfdownloaddir/src/cups-pdf /usr/libexec/cups/backend
Also, don't forget to change the permissions on this file--it needs root permissions (700) which can be changed with the following after moving cupd-pdf into the backend directory:
sudo chmod 700 /usr/libexec/cups/backend/cups-pdf
Edit the file contained in /cups-pdfdownloaddir/extra/cups-pdf.conf. Under the "PDF Conversion Settings" header, find a line under the GhostScript that reads #GhostScript /usr/bin/gs. I did not uncomment it in case I needed it, but simply added beneath it the line Ghostscript /usr/bin/pstopdf. (There should be no pre-cursor # for any of these modifications)
Find the line under GSCall that reads #GSCall %s -q -dCompatibilityLevel=%s -dNOPAUSE -dBATCH -dSAFER -sDEVICE=pdfwrite -sOutputFile="%s" -dAutoRotatePage\
s=/PageByPage -dAutoFilterColorImages=false -dColorImageFilter=/FlateEncode -dPDFSETTINGS=/prepress -c .setpdfwrite \
-f %s Again without uncommenting this, under this I added the line GSCall %s %s -o %s %s
Find the line under PDFVer that reads #PDFVer 1.4 and change it to PDFVer, no spaces or following characters.
Now save and exit editing before copying this file to /etc/cups with the following command
sudo cp cups-pdfdownloaddir/extra/cups-pdf.conf /etc/cups
Be careful of editing in a text editor because newlines in UNIX and Mac environments are different and can potentially ruin scripts. You can always use a perl command to remove them, but I'm paranoid and prefer not to deal with it in the first place.
You should now be able to open a program (e.g. Word, Excel, ...) and select File >> Print and find an available printer called CUPS-PDF. Print to this printer, and you should find your pdfs in /var/spool/cups-pdf/yourusername/ by default.
*Also, I figured this might be helpful because it helped me: if something gets screwed up in following these directions and you need to start over/get rid of it, in order to remove the driver you need to (1) remove the cups-pdf backend from /usr/libexec/cups/backend (2) remove the cups-pdf.conf from /etc/cups/ (3) Go into System Preferences >> Print & Fax and delete the CUPS-PDF printer.
This is how I successfully set up a pdf backend/filter for myself, however there are more details, and other information on customization contained in the readme file. Hope this helps someone else!
