Developing CFX tags in C++
The following sections provide information to help you develop CFX tags in C++.
Sample C++ CFX tags
Before you begin development of a CFX tag in C++, you might want to study the two CFX tags
included with ColdFusion MX. These examples will help you get started working with the
CFXAPI. The two example tags are as follows:
•
CFX_DIRECTORYLIST
Queries a directory for the list of files it contains.
•
CFX_NTUSERDB
(Windows NT only) Lets you add and delete Windows NT users.
On Windows NT, these tags are located in the \cfusion\cfx\examples directory. On UNIX, these
tags are in
cf_root /coldfusion/cfx/examples.
Setting up your C++ development environment
The following compliers generate valid CFX code for UNIX platforms:
Before you can use your C++ compiler to build custom tags, you must enable the compiler to
locate the CFX API header file, cfx.h. In Windows, you do this by adding the CFX API include
directory to your list of global include paths. In Windows, this directory is \cfusion\cfx\include.
On UNIX this directory is /opt/coldfusion/cfx/include. On UNIX, you will need
-I
<
includepath
>
on your compile line (see the Makefile for the directory list example in the cfx/
examples directory).
