#Filename   : Makefile.vxworks
#Description: makefile to be used in order to compile libcurl for VxWoorks 6.3.
#
#How to use:
#             1. Adjust environment variables at the file beginning
#             2. Open the Command Prompt window and change directory ('cd')
#                into the 'lib' folder
#             3. Add <CYGWIN>/bin folder to the PATH environment variable
#                For example type 'set PATH=C:/embedded/cygwin/bin;%PATH%'
#             4. Build the library by typing 'make -f ./Makefile.vxworks'
#             As a result the libcurl.a should be created in the 'lib' folder.
#             To clean package use 'make -f ./Makefile.vxworks clean'
#Requirements:
#             1. WinXP machine
#             2. Full CYGWIN installation (open source) with GNU make version
#                v3.78 or higher
#             3. WindRiver Workbench with vxWorks 6.3 (commercial)
