Setup:

ms c/c++: v 13.00.9466 (vs studio .net)  
mysql: v 3.23.49-nt  
ruby mysql: mysql-ruby-2.4.2a

when I run: ruby extconf.rb --with-mysql-dir=/MySQL

I get:

checking for mysql\_query() in -lmysqlclient… no  
checking for main() in -lm… yes  
checking for mysql\_query() in -lmysqlclient… no  
checking for main() in -lz… no  
checking for mysql\_query() in -lmysqlclient… no  
checking for main() in -lsocket… no  
checking for mysql\_query() in -lmysqlclient… no  
checking for main() in -lnsl… no  
checking for mysql\_query() in -lmysqlclient… no

contents of c:\MySQL\lib:

extconf.rb code:

require 'mkmf’  
inc, lib = dir\_config(‘mysql’, ‘/usr/local’)  
libs = [‘m’,‘z’,‘socket’,‘nsl’]  
while not find\_library(‘mysqlclient’, ‘mysql\_query’, lib,  
"#{lib}/mysql") do  
exit 1 if libs.empty?  
have\_library(libs.shift)  
end  
have\_header(‘mysql.h’) or have\_header(‘mysql/mysql.h’) or exit 1  
create\_makefile(“mysql”)
