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:


But when compiling I get the following error message:

/tmp/ccX6dNCL.o: In function `main':
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.
