I am new to Octave, coming from Matlab. I am trying to install a few packages, and so far none has worked. I have tried the download method from forge, then running the install command. But my question is about my latest attempt. There it is:
pkg install -global -forge io

Couldn't find any documentation on it, I am a bit lost.... (oh and btw, I can't find the config.log file! where is that gem?)
I am on MacOS catalina 10.15.7, and just followed that procedure https://flaviocopes.com/fix-xcrun-error-invalid-active-developer-path/, which solved the issues I had before which is described on that page.
cheers for any help
The error:
error: couldn't append to /Applications/Octave-4.4.1.app/Contents/Resources/usr/Cellar/octave-octave-app#4.4.1/4.4.1/share/octave/octave_packages
save: unable to open output file '/Applications/Octave-4.4.1.app/Contents/Resources/usr/Cellar/octave-octave-app#4.4.1/4.4.1/share/octave/octave_packages'

basically says it's failing to save to that file. Probably a permissions issue. Check if the file /Applications/Octave-4.4.1.app/Contents/Resources/usr/Cellar/octave-octave-app#4.4.1/4.4.1/share/octave/octave_packages exists and its permissions. That file is a database of all packages installed globally, i.e., for all users in the system.
Fixing the permission issues is dependent on what is the permissions issue you have (probably you need to run octave as root to install a global package). But maybe try to install the package for your user only, i.e., install the package without the -global flag, like so:
pkg install -forge io

I am trying to install couchbase on my macOS. I am using pip3 install couchbase to install it.
And I am getting error as

ERROR: Failed building wheel for couchbase Failed to build couchbase
ERROR: Could not build wheels for couchbase which use PEP 517 and cannot be installed directly
I also tried pip3 install --no-use-pep517 couchbase then also I am getting could not build a wheel for couchbase
I have upgraded my pip to the latest. I have python3.8. I also installed pep517.
i'm doing a program in octave in which i got
t=0:.0002:20;
Gs=tf(100,[1 10])
u1=sin(t);
y1=lsim(Gs,u1,t);
plot(t,9.95*sin(t-0.1),’r’,t,y1,’b’)
However when i write Gs=tf(100,[1 10]) in the command window it appears "warning: the 'tf' function belongs to the control package from Octave Forge which
you have installed but not loaded. To load the package, run 'pkg load
control' from the Octave prompt."
How can i load this package? I trully can't understand it...
enter image description here
enter image description here
When i load it it appears:
pkg load control

In the octave terminal, type
pkg load control
To load the control package. If you do not already have the control package installed, you need to install it. You can do so directly from Octave Forge by typing
pkg install -forge control
Note that this will install this package in your predefined 'prefix'. You can find where that is by typing
pkg prefix
If you're not sure if you have the control package installed, you can check the list of already installed packages by typing
pkg list
Type help pkg to see more details about how octave's package manager works.
In any case, the tf function belongs to the control package, and like all packages, you need to load it before you can use its functions.
Having said this, even after loading the control package, your above code doesn't work. It seems like you're calling the tf function using the wrong format.
I'm having an issue with the DBD::mysql module. This question has been asked before on this forum but a solution was not posted so I thought I would repost it. Sorry if this is not appropriate for this forum. This is my first post.
You can find the original post from bLIGU here:
Error using perl module DBD::mysql in ActivePerl 5.28 on Windws10 64bits
I have the exact same problem. I'm just upgrading my Active Perl version. Nothing else changed. I'm running the same MySql server version and this script ran fine before the update and it runs fine if I go back to version 5.20.2.2002 and use PPM to download the packages.
Note that ActiveState now requires you to build a custom version of ActivePerl with the modules online and generates an install file for you. PPM is no longer supported.
Here's the error:
install_driver(mysql) failed: Can't load 'C:/Perl64/site/lib/auto/DBD/mysql/mysql.dll' for module DBD::mysql: load_file:The specified module could not be found at C:/Perl64/lib/DynaLoader.pm line 193.
at (eval 11) line 3.
Compilation failed in require at (eval 11) line 3.
Perhaps a required shared library or dll isn't installed where expected
at C:\E22_TE~1\ICTDEV~1\Scripts\UPDATE~1.PL line 136.strong text
The file C:/Perl64/site/lib/auto/DBD/mysql/mysql.dll is present so I'm wondering if the DLL is trying to load something else and returns an error.
I Have in my Mac:
Octave-3.4.0
Gnuplot 4.2 - that I had to install because I had problems plotting - it wouldn't plot at all.
I need to load a netcdf file, the error that came was:
nc = netcdf('/users/matheuscortezi/Desktop/Pcse005/ocean_avg.nc', 'r')
error: `netcdf' undefined near line 9 column 6
So I think I don't have the netcdf comand installed, and tried installing by typing this on octave:
pkg install -global -forge octcdf
The error message that I receive from that is:
configure: error: in `/var/tmp/oct-t8XcYD/octcdf/src':
configure: error: C compiler cannot create executables
See `config.log' for more details.
the configure script returned the following error: checking for gcc... /usr/bin/gcc-4.2
checking whether the C compiler works... no
error: called from `pkg>configure_make' in file /Applications/Octave.app/Contents/Resources/share/octave/3.4.0/m/pkg/pkg.m near line 1325, column 9
error: called from:

error: /Applications/Octave.app/Contents/Resources/share/octave/3.4.0/m/pkg/pkg.m at line 354, column 9
I haven't the faintest idea about what I should do. How can I solve this problem with either:
fixing this error, or
installing a netcdf "comand pack" (i don't know the name for that) so I can use netcdf() as in the example given.
Hope I was clear enough.
It seems to me that you installed Octave from the Mac OSX App bundle. That is not recommended at all. You should install from one of the package managers as explained on Octave's wiki. As far as I know, there are 3 options for Mac (see previous link). Just search for one that also has the netcdf package.
Anyway, if you really don't want to install it through a package manager (but seems to me you really should), seems that your problem lies on gcc (the GNU C compiler). do you have it installed at all? Some packages have code in C++ or C and are also dependent on some external libraries.
EDIT using a package manager would have also solved your problem about plotting since it would install gnuplot at same time
I use OSX 10.6.8 and MySQL from XAMPP.
When I run this node.js app (app.js):
var mysql = require('mysql-libmysqlclient');
var conn = mysql.createConnectionSync();
conn.connectSync('127.0.0.1', 'root', '', 'database_name');
I see this output:
Airs0urce:nodejs airs0urce$ node app.js

Already tried couple solutions after googling.
Added mysql libs from XAMPP directory to include path this way:
export DYLD_LIBRARY_PATH=/Applications/XAMPP/xamppfiles/lib/mysql:$DYLD_LIBRARY_PATH
tried to install mysql5-devel using MacPorts, but no luck, building failed:

This is because of a config issue on Mac OS X Lion (10.7): lib/libmysqlclient.18.dylib (mysql 5.5 and above).
Step 1:
Make sure you set the path in ~/.profile
export ARCHFLAGS=-arch x86_64
export DYLD_LIBRARY_PATH=/usr/local/mysql/lib:$DYLD_LIBRARY_PATH
Step 2:
I am using rvm so, I used the following command:
rvmsudo ARCHFLAGS="-arch x86_64" gem install mysql2 -- --with-mysql-config=/usr/local/mysql/bin/mysql_config --with-opt-lib=/usr/local/mysql/lib
which has solved the issues with rails application on Mac lion and mysql x86_64.
I futzed around with this for a ton of time including setting the DVLD library path and copying the library into /usr/lib.
sudo cp /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib
Heck, anything to get it working. Finally I tried clearing the default for 64 vs 32 bit and it worked!
defaults delete com.apple.versioner.perl
Not sure if my perl is 64 or 32 bit, but my db is 64 bit and just using the default default seems to work better ;-)
