Problems using Boost, Pls Advise

of understanding diagnostics just about gets under the door. -mod}

Hi,

I'm a C++ newbie trying to use the Boost regex libraries. Here's my
situation.

My system is Red Hat Linux 9, using the Borland C++BuilderX Personal IDE
(which uses the g++ compiler).

I downloaded and installed Boost from boost.org using the command:

bjam -sTOOLS=gcc install

The install seemed to complete fine, with 2900+ targets updated.

The libraries install in /usr/local/include/boost-1_31/boost.

I created the following link:

ln -s /usr/local/include/boost-1_31/boost /usr/include/boost

I then use C++BuilderX to try and compile one of the example programs
for the regex libaries that I found in the documentation. The source
code is:

///////////////////////

#include <list>
#include <boost/regex.hpp>


unsigned tokenise(std::l ist<std::string >& l, std::string& s)
{
return boost::regex_sp lit(std::back_i nserter(l), s);
}

#include <iostream>
using namespace std;


#if defined(BOOST_M SVC) || (defined(__BORL ANDC__) && (__BORLANDC__ ==
0x550))
//
// problem with std::getline under MSVC6sp3
istream& getline(istream & is, std::string& s)
{
s.erase();
char c = is.get();
while(c != '\n')
{
s.append(1, c);
c = is.get();
}
return is;
}
#endif


int main(int argc)
{
string s;
list<string> l;
do{
if(argc == 1)
{
cout << "Enter text to split (or \"quit\" to exit): ";
getline(cin, s);
if(s == "quit") break;
}
else
s = "This is a string of tokens";
unsigned result = tokenise(l, s);
cout << result << " tokens found" << endl;
cout << "The remaining text is: \"" << s << "\"" << endl;
while(l.size())
{
s = *(l.begin());
l.pop_front();
cout << s << endl;
}
}while(argc == 1);
return 0;
}


///////////////////////



The compiler returns the following errors:

After searching around extensively, I've not come up with any solution
to my problem. Can someone please point me in the right direction? It
seems like I'm just missing some configuration step along the way.

Thanks in advance, Steve!

You are aware that there is a Boost newsgroup, right?

news://news.gmane.org/gmane.comp.lib.boost.devel

Seems that this would be much more topical there than here.

No, I did not. Sorry, I'll repost this there.

Thanks for your direction!

I don't know how to answer this without making the answer g++
specific. So those of you without g++, please bear with me.

Most libraries consist of two parts: header files, and binary
libraries containing compiled code. On most unicies, any error
about 'undefined reference to ...' or 'undefined symbol ...'
means the compiled binary libs were not found, or are
inconsistent with the header files.

You need to tell your compiler how to link in the binary library
containing the compiled code for boost::regex.

This will be different for each implementation, but for GCC, you must
tell the compiler two things:

(0) The name of the binary library, using '-l<library name>',
(1) The location of the library, using
'-L<directory containing compiled library>'

So your link command line should look something like this:

g++ linux/Debug_Build/splittest.o -lboost_regex -L/usr/local/lib

Finally see the gcc documentation: http://xrl.us/bx2p .

If it's server-specific, is it really a "newsgroup" ?

Feel free to call it what you wish. I was merely pointing out that there is a
publicly available forum for the discussion of topic-specific items -- I prefer
to call that a newsgroup.

For a suitable definition of "publicly", maybe. If I can't ask the
newsmaster to add it to my local server, then I can't access it.

Which is why, if it doesn't follow the flood-filling propagation through
multiple servers characteristic of normal newsgroups, I'd prefer to call
it something else. "BBS accessible via NNTP", perhaps?
