[Xapian-devel] 回复： A beginner in "Posting list encoding improvements"

[Hurricane Tong]

I think what i did is the same with you except i use make rather than make -sj8, and I did as root.
And I do as you wrote again:


root at hurricanetong-VirtualBox:/home/hurricanetong/xapian-1.2.17/xapian-core-1.2.17# ./configure

[...]
root at hurricanetong-VirtualBox:/home/hurricanetong/xapian-1.2.17/xapian-core-1.2.17# make -sj8
Making all in .
Making all in docs
Making all in tests

root at hurricanetong-VirtualBox:/home/hurricanetong/xapian-1.2.17/xapian-core-1.2.17# sudo make install

[...]


then


root at hurricanetong-VirtualBox:/home/hurricanetong/workspace# g++ `xapian-config --cxxflags --libs` demo2.cpp
/tmp/ccRXtBxB.o: In function `main':
demo2.cpp:(.text+0x4a): undefined reference to `Xapian::WritableDatabase::WritableDatabase(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, int)'

root at hurricanetong-VirtualBox:/home/hurricanetong/workspace# which xapian-config
/usr/local/bin/xapian-config
root at hurricanetong-VirtualBox:/home/hurricanetong/workspace# xapian-config --version

This works for me on Debian unstable with a locally installed xapian-core
1.2.17, which I built using:

$ tar xf xapian-core-1.2.17.tar.xz
$ cd xapian-core-1.2.17
$ ./configure
[...]
$ make -sj8 # quieter build, 8-way parallel
[...]
$ sudo make install
[...]

And then:

$ g++ `xapian-config --cxxflags --libs` BuildIndexDemo.cpp 
$ ./a.out
$ ls -l database
total 16

I'd check you're running the xapian-config you think you are:

$ which xapian-config
/usr/local/bin/xapian-config
$ xapian-config --version
xapian-config - xapian-core 1.2.17

If you're getting a different xapian-config, you can give an explicit path
to it:

$ g++ `/usr/local/bin/xapian-config --cxxflags --libs` BuildIndexDemo.cpp 

And that the xapian library is really installed in /usr/local/lib:

$ ls -l /usr/local/lib/libxapian*
-rw-r--r-- 1 root staff 78693312 Feb 13 15:02 /usr/local/lib/libxapian.a
-rwxr-xr-x 1 root staff      944 Feb 13 15:02 /usr/local/lib/libxapian.la
lrwxrwxrwx 1 root staff       19 Feb 13 15:02 /usr/local/lib/libxapian.so -> libxapian.so.22.6.4
lrwxrwxrwx 1 root staff       19 Feb 13 15:02 /usr/local/lib/libxapian.so.22 -> libxapian.so.22.6.4
-rwxr-xr-x 1 root staff 28428107 Feb 13 15:02 /usr/local/lib/libxapian.so.22.6.4
