LibCurl

​Libcurl is used to implement http access for the WMS, WCS and HTTP drivers.

The new WMS driver (GDAL 1.5) requires at least libcurl 7.10.7.

Win32 Build

On win32, the ​http://curl.haxx.se/download/libcurl-7.16.4-win32-ssl.zip package should be suitable for use with GDAL, in which case the declaration in nmake.opt might look like:

# Uncomment to use libcurl (for WCS)
CURL_DIR=C:\BuildStuff\libcurl-7.16.4
CURL_INC = -I$(CURL_DIR)/include
CURL_LIB = $(CURL_DIR)/lib/libcurl.dll.a
