C++ class for reading and writing XML structures. No need for a C++ code parser or special pre compiler. Specify a schema entirly in native C++. The schema is verified when XML is read and exceptions are thrown when the XML to be parse is invalid.
You can not select more than 25 topics
Topics must start with a letter or number, can include dashes ('-') and can be up to 35 characters long.

# SYNOPSIS
|
||
|
|
#
|
||
|
|
# Check if a module exists:
|
||
|
|
# AX_CXX_CHECK_QT([qt_prefix], [list-of-qt-modules], [optional-modules])
|
||
|
|
#
|
||
|

# Abort if a module does not exist:
|
||
|
|
# AX_CXX_REQUIRE_QT([qt_prefix], [list-of-qt-modules], [optional-modules])

|
#

|
# Each call to AX_CXX_CHECK_QT should have a different prefix

|
|
# value (with a few exceptions discussed later on). This value,
|
||
|
|
# usually provided in uppercase, is used as prefix to the

||
|
|
#
|

|
|
# For instance, if your prefix was to be FOO you'll be provided
|

|
|
# two variables FOO_CFLAGS and FOO_LIBS.
|
||
|
|
#
|
