| Post subject: | new to ALGLIB |
Hi there. I'm new here and trying to get ALGLIB started, but I have little problems. I'm sure sb can help me. I am programming in Linux (Debian) with gcc4.4.5. I downloaded ALGLIB and decompressed all files from the src directory. Now I wanted to test it with a gammafcn_test.cpp, which is in the same directory: Code: #include<iostream> #include "specialfunctions.h" int main () { double x = 4.5; double y = alglib::gammafunction(x); std::cout << y << "\n"; } But when compiling I get the following error message:
bessel_test.cpp:(.text+0x2b): undefined reference to `alglib::gammafunction(double)' collect2: ld returned 1 exit status What did I wrong? Thanks for helping. |

You have to add all .cpp files from ALGLIB directory to your project - to compile them along with your main .cpp file. Just including header files is not enough. |
