Unable to find Foundation Header Files on Ubuntu

Question

I have a Ubuntu server with Slicehost (now RackSpace) and am trying to get GNUstep installed so that I can compile Objective-c code.

After installing the world via apt-get and going through numerious blogs to try and get my source compiled, it now seems clear to me that I don't have the Foundation.h header files installed and I have no idea where to get these from.

They are present on my Mac, maybe I could simply copied them over to Ubuntu and it'll all be gravy - wishful thinking?

Any help on how to locate and install the Foundation.h files is appreciated.

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.

Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:

The following packages have unmet dependencies.
  libgnustep-base-dev: Depends: libxslt1-dev but it is not going to be installed
E: Broken packages

Answer 1

Which version of Ubuntu server are you running?

I'm running Ubuntu server 10.04 LTS and found my Foundation.h under /usr/include/GNUstep/Foundation/Foundation.h, it belongs to the package libgnustep-base-dev. Might be different in other versions...

Maybe you could post your output of dpkg -l | grep -i gnustep to compare our lists.
