[Xapian-discuss] how to debug xapian?

[jiangwen jiang]

Hi, Olly:
      Thanks for your reply.
      I will give my problems below, hoping you can give me a further help.

      xapian-core-1.0.16, the lastest version on www.xapian.org.
      compiling xapian-core-1.0.16 with the following command:
      ./configure --enable-log --enable-assertions && make && sudo make
install

      and using a simple example on www.xapian.org, like this:

1 #include <xapian.h>
2 #include <xapian.h>
3 #include <iostream>
4 using namespace std;
5
6 int main(int argc, char **argv)
7 {
8     // Simplest possible options parsing: we just require three or more
9     // parameters.
10    if(argc < 4) {
11       cout << "usage: " << argv[0] <<
12                " <path to database> <document data> <document terms>" <<
endl;
13       exit(1);
14    }
15
16    // Catch any Xapian::Error exceptions thrown
17    try {
18       // Make the database
19        Xapian::WritableDatabase database(argv[1],
Xapian::DB_CREATE_OR_OPEN);
20
21        // Make the document
22        Xapian::Document newdocument;
23
24        // Put the data in the document
25        newdocument.set_data(string(argv[2]));
26
27        // Put the terms into the document
28        for (int i = 3; i < argc; ++i) {
29            newdocument.add_posting(argv[i], i - 2);
30        }
31
32        // Add the document to the database
33        database.add_document(newdocument);
34    } catch(const Xapian::Error &error) {
35        cout << "Exception: "  << error.get_msg() << endl;
36    }
37}

     I can compile and run this code correctly.
     using this g++ command: g++ -g quickstartindex.cc `xapian-config --libs
--cxxflags` -o quickstartindex

     The problem is: I want to use gdb to step into xapian functions, to see
function invocation in this example code.
     for example, I set a breakpoint on line 25, and I want to use gdb step
command to step into newdocument.set_data(), but it doesn't step into this
function, just goto line 27.

     Or Should I use log file to debug this code, and see the function
invocation in xapian.

     regards
      Wen
