Need help with perl error in using DBD::mysql
When I run a perl script which uses DBD::mysql , I get the error message:
install_driver(mysql) failed: Can't load '/home/y/lib/perl5/site_perl/5.8/i686-linux-64int/auto/DBD/mysql/mysql.so' for module DBD::mysql: libmysqlclient.so.16: cannot open shared object file: No such file or directory at /home/y/lib/perl5/5.8/i686-linux-64int/DynaLoader.pm line 230.
at (eval 30) line 3
I am new to perl, but from what I understand it needs mysql.so and it knows the path.
/home/y/lib/perl5/site_perl/5.8/i686-linux-64int/auto/DBD/mysql/mysql.so is present.
Then why the problem?

The file that is missing is libmysqlclient.so.16. It comes with the mysqlclient package on some distributions.
Also, Make sure /etc/ld.so.conf contains /usr/local/mysql/lib/mysql and /usr/local/mysql/ . If not, add them and run ldconfig.

unable to install any pkg in Octave

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:

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

DBD::mysql error in ActivePerl 5.28 on Windws10 64bits, Can't load mysql.dll

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.

Perl script Can't locate Text/Template.pm in #INC [duplicate]

This question already has answers here:
Why does my Perl program complain "Can't locate URI.pm in #INC"?
(5 answers)
Closed 7 years ago.
I am trying to tune the MySQL tuner script written in Perl. But getting the error below:
root#server2 [/tmp]# perl mysqltuner.pl
Can't locate Text/Template.pm in #INC (#INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at mysqltuner.pl line 2816.
BEGIN failed--compilation aborted at mysqltuner.pl line 2816 (#1)
(F) You said to do (or require, or use) a file that couldn't be
found. Perl looks for the file in all the locations mentioned in #INC,
unless the file name included the full path to the file. Perhaps you
need to set the PERL5LIB or PERL5OPT environment variable to say where
the extra library is, or maybe the script needs to add the library name
to #INC. Or maybe you just misspelled the name of the file. See
perlfunc/require and lib.
Uncaught exception from user code:
Can't locate Text/Template.pm in #INC (#INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at mysqltuner.pl line 2816.
BEGIN failed--compilation aborted at mysqltuner.pl line 2816.
at mysqltuner.pl line 2816
It would glad to provide solution for the same.
In your perl script mysqltuner.pl, you are using a module Text::Template which is not installed in your system, that's why you are getting this warning.
You can installed it by using cpan. If you are on Linux system, open a terminal and type:
sudo cpan install Text::Template #sudo is not required if you have login as root.
If you are on windows system and using ActivePerl, use this:
ppm install Text-Template
Open Command Promt. Type in the following:
ppm install Text-Template

error installing octcdf-1.1.5

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

Need help with perl error in using DBD::mysql

/home/y/lib/perl5/site_perl/5.8/i686-linux-64int/auto/DBD/mysql/mysql.so is present.

Make sure /etc/ld.so.conf contains /usr/local/mysql/lib/mysql and /usr/local/mysql/ . If not, add them and run ldconfig.
