Native 64-bit and native 32-bit: a single source code

Overview

The recent computers (servers and desktop computers) are now equipped with "64-bit" operating systems.

The main difference between a "32-bit" system and a "64-bit" system is as follows: in "64 bits", the applications and the system are no longer limited regarding the memory allocation.

Indeed, in "32 bits", the operating system is limited to 4 GB while in "64 bits", there is nearly no limit (the limit is set to 18 billions GB).

To help you develop 64-bit sites and applications, WINDEV and WEBDEV propose:

A framework available in 32 bits and in 64 bits
The WEBDEV application server available in 32 bits and in 64 bits
The HFSQL Client/Server server available in 32 bits and in 64 bits. See HFSQL Client/Server for more details.

Remark: From version 19, HFSQL is the new name of HyperFileSQL.

How to proceed?

To create a 64-bit application

Develop your 64-bit application. A 32-bit application can be changed into a 64-bit application.
Deploy your application.

To install a WEBDEV site on a 64-bit server

Install a 64-bit WEBDEV application server on a 64-bit Web server.
Develop and deploy your WEBDEV site on the Web server.

Remark: A site compiled in 64 bits can be used with a 32-bit server or with a 64-bit server. A 64-bit server can only display 64-bit sites. If the site was not compiled with the "64 bits" option, an error will occur when the site is started.
