cgi + mySQL "revdberr,invalid database type"

[Claude Lemmel]

I have on a linux web server a MySQL database created and managed from my  
desktop Windows computer by a Revolution stack (Vista + revolution/windows  
2.81) ; it works ok.

On the same web server i installed revolution/linux 2.51 as a cgi  
application and it works ok for producing web pages.

Now i try to have my cgi scripts fetching data from my mySQL database.

If i try
put revOpenDatabase("MySQL",myURL,myBase,myName,myPassword,0) into  
databaseID
i am answered "revdberr,invalid database type"

For the param myURL, i tried the URL of my site, the IP of my site,  
"localhost" and "", but no one works.

I am sure that the params myBase,myName,myPassword are OK because they  
open succesfully the database from my desktop stack.

I guess that something is wrong in the installation of Revolution on the  
linux server. i CHMODed all revolution files to 755

Was someone successfull in managing a mySQL database from revolution as  
cgi ?

TIA
