You are probably missing the header files. I assume you're still on Ubuntu 10.04? On Ubuntu, header files are contained in the packages whose names end in
-dev. So, in this case, it's not enough to just have a libcurl package installed. Have you run the mk/linux/setupBuildDeps.sh script as discussed on the wiki page which contains the build instructions for Linux (using cmake)? It is meant to install the packages you need, or should at least offer a hint which you can then expand on.
Some general hints: You are welcome to ask your questions both here and on IRC. When you do on IRC, please keep in mind that there is no way to respond to you once you've left. So if you cannot stay around for at least half an hour after asking your question it may be better not to ask it
there in the first place but to bring it here instead. We also don't have public logs of the IRC channels at this time and so, in contrary to here, what you post there is not searchable by you, the developers, or anyone, although having this possibility can be helpful when other people run into the same issues, or when developers want to review the issue you ran into to make things more smooth. And finally, on IRC, please don't paste more than 3 lines at once, use a pastebin (such as
paste.megaglest.org or
pastebin.com) instead. This a little bit more work but keeps IRC usable when it's busy and also makes the text you are providing more readable in most cases. Thank you!
