That's a puzzle, isn't it?

I usually solve icky problems like this by doing things like running g++ with
the --verbose flag to see what it's doing in more detail
and/or by running it under strace -o foo.log
and then doing
  grep -i eikdialg.h foo.log
to see what happened when it tried to open the file.

You might also check the case of the filename and the permissions on the file.
