Hi all,<br><br>I am new to boost library.<br><br>First of all, I apologize that my question will be pretty basic to people in this mailing list,<br>nevertheless I have spent 30 min + to figure it out and couldn't find the answer.<br> So, here it goes...<br><br>I need to find which library (lib*.a) file contains the "ibeta" function which is defined under<br>boost/math/special_functions/gamma.hpp.<br><br>When I compile the following simple test.cpp<br> -----------------------------------------<br>#include <boost/math/special_functions/gamma.hpp><br> #include <iostream><br> <br> using namespace std;<br> using namespace boost::math;<br> <br> <br> int main() {<br> � cout << "it is my birthday...\n"; <br> � cout << ibeta(5, 2, 0.5) << "\n";<br> }<br>-----------------------------------------<br><br>with this command line,<br><br>g++ -I /my_own_boost_root_path/ test.cpp<br><br>I get� link error message (undefined reference)<br><br>/tmp/ccgrrT4l.o: In function `main':<br> test.cpp:(.text+0xc1): undefined reference to `boost::math::tools::promote_args<int, int, double, float, float, float>::type boost::math::ibeta<int, int, double>(int, int, double)'<br>collect2: ld returned 1 exit status<br> <br>I know that I just need to put the correct library in the command line, but I can't figure it out.<br><br>There are 6 lib*.a files in<br>boost_build_dir/bin.vs/libs/math/build/gcc-4.1.2/release/link-static/threading-multi/<br> <br>I tried to each of them at the end of my compilation command line, in the hope that "ibeta" is contained in one of them, but I failed.<br><br>1. Where should I look to find the lib*.a that contains "ibeta"� (ibeta is incomplete beta function integral)<br> 2. In general, how do I figure out which lib*.a to use, when I need to use specific classes or functions?<br>�� (I have looked at "getting started", and "libraries" for proper documentation, but they explain in detail<br> ��� the available libraries, but, not what lib*.a file to use for specific functions...)<br>3. Is it possible� that "ibeta" is not built<br><br>Thanks a lot !<br><br><br><br>
