I take the same error messages on different computers trying to use Octave in terminal:
wavread('example_audio.wav')
error: wavread: No such file or directory
error: called from:
error: /usr/share/octave/3.8.1/m/audio/wavread.m at line 74, column 7
By the way, example_audio.wav is a working file (I tried in VLC player.) and I start Octave in the directory where .wav resides.
What is the problem and how can I resolve it?
EDIT: SOLVED. It seems the problem to be that I add the .wav file after I start Octave. After, exiting and starting again, it resolved.
Double check the file name. Use tab to auto complete the filename to check if its found on your path.

I am new to Rmarkdown and trying to learn how to knit a code. when I run the sample code and knit, it gives me the following error:
*

I thought perhaps I should install package"Pandoc.utils" but once I called the package in R, it gave this error:
package ‘pandoc.utils’ is not available (for R version 3.6.0)
Is this because I have the latest version of R and it cant install the older version of pandoc? does anyone know what is going on?
It looks like rmarkdown can't find pandoc. RStudio typically includes the pandoc files in your\path\to\Rstudio\bin\pandoc. When you open RStudio, it secretly sets an environment variable named RSTUDIO_PANDOC which rmarkdown uses to find pandoc.
Run the command Sys.getenv("RSTUDIO_PANDOC"), which should return the location of your pandoc installation. If it doesn't, that is likely to be your problem.
Once you find where RStudio is installed, you can set this environment variable with Sys.setenv(RSTUDIO_PANDOC = "your/path/to/Rstudio/bin/pandoc"). After that (assuming this is your problem) you should be able to knit the document as expected.
I had this problem at my Windows 10 desktop, and fixed it.
There is a long command before your error in the R Markdown terminal if you use Rstudio. It may looks like this:
"C:/Users/15510/AppData/Local/Pandoc/pandoc" ...
And it is inconsistent with my Sys.getenv("RSTUDIO_PANDOC"), which is "C:/Program Files/RStudio/bin/pandoc/pandoc"
So I remove my pandoc path(C:/Users/15510/AppData/Local/Pandoc/pandoc) from the system environment in Windows, and then the rmd can run successfully with the terminal saying this:
"C:/Program Files/RStudio/bin/pandoc/pandoc" ...
P.S. I guess you have installed pandoc in your user directory, maybe you can check your system path of the computer.
Unfortunately, none of the above worked for me. Surprisingly, disconnecting from the internet helped. May be this will help someone else too.
For some time, I've been using some .mex files I created. Now I have a new computer. I copied all the files over and reinstalled Cygwin and Octave. When I try to execute any of the .mex routines I get a message like:
error: testm: /cygdrive/c/A/Cwin/...../quad.mex: failed to load: No such file or directory
The file is definitely there and I'm having no trouble loading .m files from the same directory. It does not say there is anything wrong with the file. I'm guessing this is some sort of configuration problem. I am running Octave 4.2.1. When I start it, I get the following message:
Octave was configured for "x86_64-unknown-cygwin".
Could that have something to do with it? I think I'm developing x64 paranoia, since all my Excel .dll macros no longer work either. Thanks.
I am trying to move my location on disk of a Bolt.cm install. Config.yml doesnt have any details of location.
When I rename the directory I receive app config issues as well as this :
Fatal error: Uncaught exception 'Bolt\Exception\LowLevelDatabaseException
Thrown from within Bolt. Seems like I need to update a config file but I don't see one with the path do web root or path to database stored.
Does such a file exist?
You need to flush the cache.
This can be done from the command line by:
php app/nut cache:clear
Or inside app/cache/ you will find the file config_cache.php that can be safely deleted.
I recently upgraded our MediaWiki installation to version 1.24.2
Now when I access the Special pages at http://www.myserver.com/index.php/Special:Specialpages I get this error:
Warning: require(/www/local/path/to/web_directory/public_html/includes/specials/SpecialAllPages.php) [function.require]: failed to open stream: No such file or directory in /www/local/path/to/web_directory/public_html/includes/AutoLoader.php on line 1282
Fatal error: require() [function.require]: Failed opening required '/www/local/path/to/web_directory/public_html/includes/specials/SpecialAllPages.php' (include_path='.:/usr/local/share/pear') in /www/local/path/to/web_directory/public_html/includes/AutoLoader.php on line 1282
Can someone please point me at the right direction to solve this problem?
I have already searched the entire interweb for an answer...
PHP version: 5.3.10
MySQL version: 5.5.31
Apache version: 2.2.22
It seems there was an error while upgrading/transferring the files to your server.
It seems you solved your problem by yourself, however: You shouldn't update mediawiki's files on top of another version. Instead, you should delete the old installation (keeping the files you need like LocalSettings.php, images/ and so on) and upload a new copy of the new version you want to use. See https://www.mediawiki.org/wiki/Manual:Upgrading for a detailed upgrading tutorial. Following these steps should avoid such problems the next time :)
I found out what the problem was.
I installed v 1.24.2 on top of version 1.21
By some reason the file SpecialAllPages.php was named SpecialAllpages.php with a small 'p'.
After renaming the file to SpecialAllPages.php the same error was triggered regarding the file SpecialAllMessages.php that was named SpecialAllmessages.php
After renaming that file also, everything works fine again.
I am in a serious problem while installing mysql on ubuntu 12.04 32 bit. when i start mysql with command ''./mysql.server start'' I got this error Manager of pid file quit without updating pid file. I installed ''mysql-5.1.39-linux-i686-glibc23''.
I thoroughly search for the solution to fix this error but cannot resolve it yet. I copied my-medium.cnf file to the /etc directory and rename it by my.cnf also edited this file in the section ''The mysql Server'' and add these lines ''datadir = /exports/disk0/data'' but could fix this problem. Can any one help on this.
The message bout the pid file is kind of a red herring. It just means that the init script /etc/init.d/mysql did not return success. The root cause could be a variety of things, for example file permissions problems in your datadir, or the config file contained an invalid line, or dozens of other possible problems.
When you get the error about the pid file, the first thing you should do is to go read the MySQL error log file. Usually this is in the data directory, and it may be called hostname.err (where "hostname" is the name of the server you installed MySQL).
Search the file for any lines reporting "ERROR" and then use Google to research the error.
