I am trying to compile something for the last day and it is not working at all. following is my g++ command:

g++ -O3 -Wall -march=native -mfpmath=sse -fopenmp  -fno-trapping-math -fsingle-precision-constant -funroll-loops -g -I../../include/  `pkg-config --cflags opencv` -Wl,--start-group  ../../lib/libmoped.a -lm  -lm `pkg-config --libs opencv` -lgomp -lGLEW -lglut -lIL -lm camera.cpp -o camera

and I am getting the following error:

/usr/bin/ld: ../../lib/libmoped.a(ProgramGPU.o): undefined reference to symbol '__expf_finite@@GLIBC_2.15'
/usr/lib/gcc/x86_64-linux-gnu/4.6/../../../x86_64-linux-gnu/libm.so: error adding symbols: DSO missing from command line

I tried adding -lm multiple times, in the beginning, in the end as well as several times after each of the libraries to resolve circular dependency, but still I get the same error. I tried --start-group and put everything inside as shown in the provided command, and still end up getting the same error with the error. What is wrong?

Which version of glibc do you have installed? – Wintermute Apr 13 '15 at 14:13
it looks like a linking problem.. Did you check your link? – goGud Apr 13 '15 at 14:15
@Wintermute, I am using g++/gcc 4.6 – krips89 Apr 13 '15 at 14:22
@goGud, checking link of what? I don't have a binary built yet. – krips89 Apr 13 '15 at 14:23
That's good to know, but which version of glibc? If it's older than 2.15, that would be important to know. – Wintermute Apr 13 '15 at 14:23
@Wintermute, it is 2.19 I just found out. – krips89 Apr 13 '15 at 14:38
