[ebymohan]

i just started studing TBB a few days ago i hav read a lot

but to better understand i need to execute some programs

i hav downloaded VS 2010 and intel parelel studio

i can execute the compiled examples given in the site

but cant compile the code gives me error like library files missing

plz tell me how to add lib files

Hi,
Have you tried the "Getting Started" document that comes with every copy of Intel TBB? It has detailed information about how you could compile and run your program that uses Intel TBB.

Thanks,
Krishna

1st of all thanks for the reply

yes i hav

and i hav installed VS2010 and intel parallel studio(both evaluation version)

i can execute the programs provided with the package that has VS solution file in it

but cannot even compile the same when i copy paste the source into a newly created file or c++

for example i cannot compile the following code(this is a example (substring finder) comming along with the package)

#include

#include

#include

#include "tbb/parallel_for.h"

#include "tbb/blocked_range.h"

using namespace tbb;

using namespace std;

static const size_t N = 23;

class SubStringFinder {

const string str;

size_t *max_array;

size_t *pos_array;

public:

void operator() ( const blocked_range& r ) const {

for ( size_t i = r.begin(); i != r.end(); ++i ) {

size_t max_size = 0, max_pos = 0;

for (size_t j = 0; j < str.size(); ++j)

if (j != i) {

size_t limit = str.size()-max(i,j);

for (size_t k = 0; k < limit; ++k) {

if (str[i + k] != str[j + k]) break;

if (k > max_size) {

max_size = k;

max_pos = j;

}

}

}

max_array = max_size;

pos_array = max_pos;

}

}

SubStringFinder(string &s, size_t *m, size_t *p) :

str(s), max_array(m), pos_array(p) { }

};

int main() {

string str = { string("a"), string("b") };

for (size_t i = 2; i < N; ++i) str = str[i-1]+str[i-2];

string &to_scan = str[N-1];

size_t num_elem = to_scan.size();

size_t *max = new size_t[num_elem];

size_t *pos = new size_t[num_elem];

parallel_for(blocked_range(0, num_elem ),

SubStringFinder( to_scan, max, pos ) );

for (size_t i = 0; i < num_elem; ++i)

cout << " " << max << "(" << pos << ")" << endl;

delete[] pos;

delete[] max;

return 0;

}

this is a example (substring finder) comming along with the package

compiling this gives following errors

In the Solution Explorer menu, right click your project, and go to Properties. Then set two things:

• Configuration Properties C++ General Additional Include Directories: Add $(TBB30_INSTALL_DIR).
• Configuration Properties Linker Additional Library Directories: Add $(TBB30_INSTALL_DIR)\lib\ia32\vc10)

You can look at these settings on the example projects to see the proper settings. They might differ from what I have above, which I copied from a VS2010 project of mine that I happen to have open at the moment.

Thank u very much to both of u

now i can study this in more detail
