I seem to run into some trouble.
I succeeded in building the source code of Xapian in ubuntu,
but when I write a demo c++ application
using namespace std;
Xapian::WritableDatabase db("database", Xapian::DB_CREATE_OR_OPEN);
I can't get it built.
hurricanetong at hurricanetong-VirtualBox:~/workspace$ g++ -L/usr/local/lib -lxapian-1.3 BuildIndexDemo.cpp
/tmp/cc7JwYty.o: In function `main':
BuildIndexDemo.cpp:(.text+0x52): undefined reference to `Xapian::WritableDatabase::WritableDatabase(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, int, int)'
BuildIndexDemo.cpp:(.text+0x7b): undefined reference to `Xapian::WritableDatabase::~WritableDatabase()'
BuildIndexDemo.cpp:(.text+0xa0): undefined reference to `Xapian::WritableDatabase::~WritableDatabase()'
In /usr/local/lib, there are libxapian-1.3.so, libxapian-1.3.a, libxapian-1.3.so.3, libxapian-1.3.so.3.0.0
I also set LD_LIBRARY_PATH=/usr/local/lib
in /etc/ld.so.conf.d, there are also /usr/local/lib
I also restart my machine, but I still can't make it.

If you're on Windows, the way of doing this is to virtualise (either VirtualBox, which is free, or VMWare, which isn't but you can sometimes find prepackaged VMs which work with their free version). I'd recommend using a recent Ubuntu (13.04 or 13.10) for preference, although 12.04 (which is the Long Term Support version) shouldn't present too many pain points.
If you need help, I can probably be of assistance. Keeping track of which commands you type (eg by using script(1)) is a good idea if you're unfamiliar with linux and think you might run into problems.
