I try to install luasql-mysql with luarocks (Lua 5.3.5, LuaRocks 3.0.3). I have Mysql Connector C 6.1 installed in directory "C:\Program Files\MySQL\MySQL Connector C 6.1". I have MinGW installed in C:\TDM-GCC-64 dir.
When I run command
luarocks --from=http://rocks.luarocks.org/dev install luasql-mysql cvs-1 MYSQL_INCDIR="C:\mysql-5.7.23-winx64\include" MYSQL_LIBDIR="C:\Program Files\MySQL\Connector C++ 8.0\lib64"
I get the error

How to specify paths correctly?
I could find workaround solution. Here is steps to make Lua 5.1 running in Windows 10 x64 Pro connect to Mysql server:
Get the latest Lua 5.1 from https://code.google.com/archive/p/luaforwindows/downloads
Install it. I have to remove all previous Lua and LuaRocks installations in my workstation
Added environment variable LUA_CPATH with value:
C:\Program Files (x86)\Lua\5.1\clibs\?.dll;C:\Program Files (x86)\Lua\5.1\clibs\luasql\?.dll
Run mysql lua script in NEW cmd

Initially, the error seemed to be that I hadn't install the python3 dev tools correctly, so I reinstalled python3. However, I know believe this is an issue with my installation of MySql.
I reinstalled python3 with suggested packages. I also ensured configuration files were added for mysql.
You are in a virtual environment using python 3.9 instead of python 3.8 shipped with Ubuntu 20.04 try :
sudo apt install python3.9-dev
This package installs all headers files needed to build python3.9 instead of 3.8
I'd like to install the following UDF's from sam J levy's site
I have run through the windows (32 bit) installation with wamp for my testing server with no problem. Now I have my proper server running centOs 6.4. I have copied the .so files to
usr/lib64/mysql/plugin/damlev.so
I then try to run one of the sql statements to create the function
CREATE FUNCTION damlev RETURNS INTEGER SONAME 'damlev.so';
And get the following error
1126 - Can't open shared library 'damlev.so' (errno: 22 /usr/lib64/mysql/plugin/damlev.so: wrong ELF class: ELFCLASS32)
What Am I doing wrong. Is it because the server is 64bit?
Edit Bounty Started:
If more details about the server are required I can gladly supply them. I need this function installed.
It seems that you're trying to use the damlev.so library included in the damlev.zip file of the Levi's site, but that library is for an Ubuntu 32-bit system, therefore it cannot work on your Centos 64-bit system, so you'll have to compile from sources.
As a prerequisite, you must install the g++ compiler and the mysql development libraries:
yum install gcc-c++ mysql-devel
Also, if you don't have wget and unzip, install them with the following command:
yum install wget unzip
Then download the source code and unzip it somewhere:
cd tmp
mkdir damlev
cd damlev
wget http://samjlevy.com/wp-content/uploads/2011/03/damlev.zip
unzip damlev.zip
cd src
Finally compile, install the plugin and restart the mysql server:
g++ -fPIC -I /usr/include/mysql/ -o damlev.so -shared damlev.cpp
cp damlev.so /usr/lib64/mysql/plugin/
service mysql restart
Please note that all the above command must be run as "root".
Hey all, I'm trying to install 64-bit MySQL on Snow Leopard for a rails app.
I've installed it from the dmg and I can get to mysql fine from the command line. Based on various blog posts as well as the other topics here on Stack, I shut down mysql, uninstall the mysql gem, and then try to update the gem with the following:
sudo env ARCHFLAGS='-arch x86_64' gem install --verbose --no-rdoc --no-ri mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
That produces the following:

Those two warnings at the end seem ominous. I then go to my rails app and run
rake db:migrate
And get:
dyld: NSLinkModule() error
dyld: Symbol not found: _mysql_affected_rows

Trace/BPT trap
And that's as far as I'm able to get. I've tried installing MySQL via the dmg and via macports and I seem to run into this error in both cases.
I'm kind of a noob when it comes to rails; any light anyone can shed would be wildly appreciated. Thanks!
--- EDIT ---
In response to John's (and khelll's) answers below:
When I do the first command that John specified, I get:
No definition for next_result
No definition for field_name
No definition for field_table
There's about 40 lines of this. I assumed this was because of the documentation. But when I do rake db:migrate I get:
dyld: NSLinkModule() error
dyld: Symbol not found: _mysql_affected_rows
Referenced from: /usr/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle
Expected in: flat namespace
in /usr/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle
Trace/BPT trap
Using the ARCHFLAGS command produces the error I specified earlier.
--- SECOND EDIT ---
I should add that I did not install from source. After peeking at the Hivelogic instructions again, I went down this route.
When I tried to run:
./configure --prefix=/usr/local/mysql --with-extra-charsets=complex \
--enable-thread-safe-client --enable-local-infile --enable-shared \
--with-plugins=innobase
I got:
config.status: creating zlib/Makefile
dyld: Library not loaded: /opt/local/lib/libintl.8.dylib
Referenced from: /opt/local/bin/gawk
Reason: no suitable image found. Did find:
/opt/local/lib/libintl.8.dylib: mach-o, but wrong architecture
./config.status: line 1782: 69228 Done(141) eval sed ç"ç$ac_sed_extraç" "$ac_file_inputs"
69229 Trace/BPT trap
So I did:
sudo port deactivate gettext
sudo port activate gettext #0.17_3
However, after following all the steps, reinstalling the gem, upon rake db:migrate I still get:
dyld: NSLinkModule() error
dyld: Symbol not found: _mysql_affected_rows
Referenced from: /usr/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle
Expected in: flat namespace
in /usr/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle
Trace/BPT trap
---- THIRD EDIT ----
Okay - I believe what's happening here is that, even though I'm specifying the 64 bit gem above, it's installing the 32 bit version. I do:
file /usr/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle
And get:
/usr/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle: Mach-O bundle i386
So it would seem I keep installing the 32 bit version
I installed it from source following these instructions on Hivelogic and it works great. Then I installed the MySQL RubyGem using:
sudo gem install mysql -- --with-mysql-dir=/usr/local/mysql
First I wanted to build the DBD::mysql package. That kept failing because whatever make resulted in could not be loaded for the tests with a Symbol not found: _is_prefix. So I assumed that cpan might be a tad old. I know it's a random assumption, but cpan did tell me to install the latest Bundle::CPAN.
Who's successfully installed either DBD::mysql or Bundle::CPAN on Mac OS X 10.5? Could you recommend any thing I could be doing differently?

Okay, if you get these errors I now know the following:
MySQL 5.1 for Mac OS X x86_64 is not compatible with DBD::mysql (yet). Install the 32-bit x86 version, and try again. You'll succeed. I wish the perl Makefile.pl would just tell you that in a banner.
Bundle::CPAN had issues because I wasn't installing as root. Why that makes it report circular references instead of installation permission issues, I'll never understand.
Please add a comment if and when this became outdated information.
Installing the (beta) 5.4.1 64 bit version of mysql, available from their developer website, fixes the issue. Tested on Snow Leopard.
Did you try installing Bundle::DBD::mysql?
I haven't dealt with this problem, but I found that MacPorts cleaned up all my UNIX incompatibility problems. You might want to try that before enduring too much pain and suffering.
Where is it complaining about a circular dependency? It looks like you are trying to link to an incompatible version of the mysql libraries. The symbol it's looking for isn't in the library you loaded. I don't think this is a problem caused by CPAN.pm or the cpan script.
Some questions:
Who compiled perl? Is this Apple's perl?
Who compiled mysql? Is that your own version since it's in /usr/local?
Did you previously compile other versions? I start with a compile to ensure everything points to the right places.
Installing latest beta 64bit version of Mysql fixed problem on my computer.
