I am trying to integrate curl-library with the software on an embedded system running on VxWorks 6.2. The ultimate goal is to use the curl Library calls from this code. It is an embedded system and hence I am doing cross compilation.
Cross-compilation or not makes very little difference.
Here is what I am going to do: 1. Get the curl code for one of the OS from the list given in the download wizard
Don't. The packages provided for particular operating systems are primarily binaries for those, you don't want that. You want the main and full source code package.
2. Make the necessary changes in the code and makefile for it to work with my system. (Hope it would not require too many changes.)
It really depends on your compiler (setup) and what primitives your operating system provides. AFAIK, vxworks has an optional POSIX layer that might reduce the amount of necessary work.
I do not want to go for the OS independent version as I feel, porting from a code base which is close to VxWorks would be easier than starting with the full blown OS independent version and pruning it down.
The "independent version" is the full version that is made to get built to all those versions libcurl can run on. That's the version you want to base any such work on.
I guess you could get inspired with how the windows port is made, the symbian one or the riscos one. They have their own hand-made lib/config-[os].h file that defines it's setup and then basically the rest of the library code should remain untouched.
