[hypertable-user] Hypertable Example

[Zhuo Yin]

Hi, all:

I downloaded the latest version of Hypertable 0.9.3.1-alpha, and trying to write a very simple c++ client test program and run it on Fedora 12.

What I want to do is just try to run sample code.

I met the problem probably the static library cannot to linked, which bothers me a lot:
Here is my test code:
========================================================
#include <Common/Compat.h>

#include <iostream>
#include <fstream>
#include <string>

#include <Common/System.h>
#include <Common/Error.h>

#include <Hypertable/Lib/Client.h>
#include <Hypertable/Lib/KeySpec.h>

using namespace Hypertable;

int main(int argc, char* argv[]) {
ClientPtr client_ptr;
TablePtr table_ptr;
TableMutatorPtr mutator_ptr;
KeySpec key;

const char* install_dir = "/opt/hypertable/current/";

client_ptr = new Client( System::locate_install_dir(install_dir) );

return 0;
}
==========================================================

g++ -g -Wall -fPIC -I/usr/include -I/usr/include/python2.6 -I/opt/hypertable/current/include/ -c test.cpp -Wno-deprecated -o test.o
g++ -L/usr/lib64 -L/opt/hypertable/current/lib/ -o test -lHypertable -lHyperComm -lHyperCommon -lHypertable test.o
test.o: In function `main':
/home/zyin/ht-dev/test.cpp:23: undefined reference to `Hypertable::System::locate_install_dir(char const*)'
/home/zyin/ht-dev/test.cpp:23: undefined reference to `Hypertable::Client::Client(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, unsigned int)'
collect2: ld returned 1 exit status
make: *** [test] Error 1


I got this problem above, it seems the object file compiled fine, but cannot find the functions in static libraries when linking. Is there any special version requirement to compile the simple client program?

Can someone give me a hint? It's hard to compile from source tar ball, if I can get those compiled binaries works, that's the best

Thanks,
Zhuo Yin

Hi Zhuo,

I'm not sure exactly what is going on here.  The symbols 'Hypertable::System::locate_install_dir' and 'Hypertable::Client::Client' should be found in libHyperCommon and libHypertable, respectively.  Is it possible that this is a link line ordering problem?  Maybe try changing this:

g++ -L/usr/lib64 -L/opt/hypertable/current/lib/ -o test -lHypertable -lHyperComm -lHyperCommon -lHypertable test.o

to this:

g++ -L/usr/lib64 -L/opt/hypertable/current/lib/ -o test -lHyperCommon -lHypertable -lHyperComm -lHyperCommon -lHypertable test.o

and see if that fixes the problem.

- Doug

[Zhuo Yin]

Hi, Doug:

Thanks for reply.

I tried your suggestion:

g++ -g -Wall -fPIC -I/usr/include -I/usr/include/python2.6 -I/opt/hypertable/current/include  -c test.cpp -Wno-deprecated -o test.o

g++ -L/usr/lib64 -L/opt/hypertable/current/lib -o test -lHyperCommon -lHypertable -lHyperComm -lHyperCommon test.o 

test.o: In function `main':

/home/zyin/ht-dev/test.cpp:23: undefined reference to `Hypertable::System::locate_install_dir(char const*)'

/home/zyin/ht-dev/test.cpp:23: undefined reference to `Hypertable::Client::Client(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, unsigned int)'

collect2: ld returned 1 exit status

make: *** [test] Error 1

I still got this.

The package I installed is hypertable-0.9.3.1-linux-x86_64.rpm,  because I'm using Fedora 12 x86_64 system.

$ ls /opt/hypertable/current/lib/

java                                libcrypto.so.0.9.8  libHyperCommon.a     libHyperThrift.a        libsigar-amd64-linux.so   libz.so.1

libboost_filesystem.so.1.40.0       libdb_cxx-4.8.so    libHyperDfsBroker.a  libHyperThriftConfig.a  libssl.so.0.9.8           perl

libboost_program_options.so.1.40.0  libevent-1.3e.so.1  libHyperDfsCmds.a    libHyperTools.a         libstdc++.so.6            php

libboost_system.so.1.40.0           libexpat.so.1       libHyperRanger.a     liblog4cpp.so.5         libtcmalloc_minimal.so.0  py

libboost_thread.so.1.40.0           libgcc_s.so.1       libHyperspace.a      libncurses.so.5         libthriftnb.so.0          rb

libceph.so.1                        libHyperComm.a      libHypertable.a      libreadline.so.5        libthrift.so.0

I was wondering, is there any problem with the static 64bit rpm package?

Thanks,

Zhuo Yin

Hi Zhuo,

There is a tool called 'nm' that will dump the symbol table for an object file or library archive.  It should ship with Fedora by default.  Try running nm on libHyperCommon and libHypertable and grepping for these two symbols to see if they exist in the libraries.

Hi, Doug:

Here is the output:

in libHyperCommon.a, it seems I can find Hypertable::System::locate_install_dir, but for all libHypertable.a, libHyperComm.a, libHyperCommon.a, I can't find the  Hypertable::Client::Client

But why the ld cannot find the `Hypertable::System::locate_install_dir(char const*)', and where is Hypertable::Client::Client.

Thanks,

Zhuo Yin

Hi Zhuo,

When I inspect the libraries, it appears that the symbols are there.  Here's what I did:

$ wget http://package.hypertable.org/hypertable-0.9.3.1-linux-x86_64.tar.bz2

$ tar xjvf hypertable-0.9.3.1-linux-x86_64.tar.bz2 

$ nm hypertable-0.9.3.1-linux-x86_64/opt/hypertable/0.9.3.1/lib/libHypertable.a | c++filt | fgrep "Hypertable::Client::Client"

0000000000005c20 T Hypertable::Client::Client(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, unsigned int)

00000000000052e0 T Hypertable::Client::Client(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, unsigned int)

0000000000006210 T Hypertable::Client::Client(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, unsigned int)

0000000000005780 T Hypertable::Client::Client(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, unsigned int)

$ nm hypertable-0.9.3.1-linux-x86_64/opt/hypertable/0.9.3.1/lib/libHyperCommon.a | c++filt | fgrep "Hypertable::System::locate_install_dir"

0000000000001320 T Hypertable::System::locate_install_dir(char const*)

The 'T' indicates that the symbol is in the text (code) section.

Doug:

Thanks for the command,

I did the same thing as you did. The command output is the same. seems the library has such functions.

But I don't know why it cannot be linked. I changed the order of g++ command line but still get no luck, which really bothers me. Do you have any suggestion for this?

The easiest way to find out the link line for a test program would be
leverage the cmake. Go to the examples build directory and type make
clean and make VERBOSE=1

[Zhuo Yin]

Hi, Doug, Luke:

1. I tried go to /opt/hypertable/current/examples

I edited CMakeCache.txt:
changed
CMAKE_CXX_FLAGS:STRING
to
CMAKE_CXX_FLAGS:STRING=-I/opt/hypertable/current/include/

and
CMAKE_EXE_LINKER_FLAGS:STRING
to
CMAKE_EXE_LINKER_FLAGS:STRING=-L/opt/hypertable/current/lib

then execute:
$ make clean
$ make VERBOSE=1

Here is the error message I got, it's the same link problem as I got from my previous Makefile example:

2. another separate issue regarding thrift python client:

Here is how I run the sample code, I started the local server before running this python program:

$ cd /opt/hypertable/current/lib/py

Hi Zhou,

I've also worked on the problem for 1 days and now solved it by Luke's
reply.

The actually link command I found is:

g++ -g -fPIC "apache_log_load.o" -o apache_log_load \
-rdynamic \
-L/opt/hypertable/current/lib -L/usr/local/lib \
-lHypertable -lHyperComm -lHyperCommon -lHyperspace -lHyperTools -
ldb_cxx -lexpat -lHyperTools \
-lpthread \
-lboost_iostreams -lboost_program_options -lboost_filesystem -
lboost_thread -lboost_system \
-llog4cpp -lreadline -lncurses -lz -lsigar-amd64-linux -ldl -lncurses
\
-lsigar-amd64-linux -lcurses -lHyperDfsBroker \
-lHypertable

Please note:
1. there's two "-lHypertable"
2. extra libs referenced like db_cxx and expat

Wish you good luck. And thanks Luke for the hint!

Best,

Kevin, Luke, Doug -

Thanks for patient explain.

But the two -lHypertable seems weired, any reason to use two -lHypertable?

and like Kevin said, miss any one of this will not working.

Thanks,
Zhuo Yin

Because libHyperDfsBroker and libHypertable has a circular dependency
introduced by Sanjit's checkin on 4/1 for Issue 259. cmake takes care
of the link dependencies automatically. It works for static libs. But
dynamic libs now no longer builds in the new release.

There is a plan to refactor the libraries to remove the dependency, though.

We can fix it by moving the FileSystem class into the Common library (and possibly move the Path class in Common/Filesystem.h to FileUtils or rename it to avoid confusion) .

Hi all
I have the same problem I want to compile a very easy example I have make a littel change to the /opt/hypertable/current/examples/apache_log/apache_log_load.cc:

My example is:
#include <Common/Compat.h>


#include <cstdio>

#include <Common/System.h>
#include <Common/Error.h>

#include <Hypertable/Lib/Client.h>
#include <Hypertable/Lib/KeySpec.h>

using namespace Hypertable;

using namespace std; 

namespace {

  const char *usage =
    "\n"
    "  usage: apache_log_query <row-prefix> [ <cf> ... ]\n"
    "\n"
    "  Queries the table 'LogDb' for all rows that start\n"
    "  with <row-prefix>.  If no column families are\n"
    "  specified, then all column families are returned.\n"
    "  Otherwise, just the column families specified by\n"
    "  the <cf> arguments are returned\n";
}


int main(int argc, char **argv) {
  ClientPtr client_ptr;
  TablePtr table_ptr;
  TableScannerPtr scanner_ptr;
  ScanSpecBuilder scan_spec_builder;
  Cell cell;
  String end_row;
 
  if (argc <= 1) {
    cout << usage << endl;
   return 0;
  }

  try {

    // Create Hypertable client object
    client_ptr = new Client();

    // Open the 'LogDb' table
    table_ptr = client_ptr->open_table("archive2");

     // setup row interval
    end_row = (String)argv[1];
    end_row.append(1, 0xff);  // next minimum row
    scan_spec_builder.add_row_interval((const char *)argv[1], true, end_row.c_str(), false);


    // setup scan_spec columns
   // for (int i=2; i<argc; i++)
    //  scan_spec_builder.add_column(argv[i]);

    // Create a scanner on the 'LogDb' table
    scanner_ptr = table_ptr->create_scanner(scan_spec_builder.get());

  }
  catch (Exception &e) {
    cerr << e << endl;
    return 1;
  }

  // Iterate through the cells returned by the scanner
  while (scanner_ptr->next(cell)) {
    printf("%s\t%s", cell.row_key, cell.column_family);
    if (*cell.column_qualifier)
      printf(":%s", cell.column_qualifier);
    printf("\t%s\n", std::string((const char *)cell.value, cell.value_len).c_str());
  }

  return 0;
}

for complile I use the follow command:

g++ -I/opt/hypertable/current/lib -I/opt/hypertable/current/include -L/usr/local/lib -L/usr/lib -lHyperCommon -lHypertable -lHyperComm -lHyperCommon -lHypertable -Wno-deprecated -c test.cc
The output of this command create a test.o file

g++ -o test test.o -L/opt/hypertable/current/lib -lHypertable -lHyperComm -lHyperCommon -lHyperTools -llog4cpp -lexpat -lboost_thread -lboost_iostreams -lboost_program_options -lboost_system -lsigar-x86-linux -lHyperspace -lz -lcurses
When I thorow the command above the output is:
