Hello rooters,

When I try to compile the attached macro I get this error:

root [1] .x fitCaMnMixing.C+ (4)
Info in <TUnixSystem::ACLiC>: creating shared library /home/rmason/Programming/rootmac/fitCaMnMixing_C.so dlopen error: /home/rmason/Programming/rootmac/fitCaMnMixing_C.so: undefined symbol: _ZN13TLinearFitterC1Ev Load Error: Failed to load Dynamic link library /home/rmason/Programming/rootmac/fitCaMnMixing_C.so /usr/lib/gcc/i686-pc-linux-gnu/4.1.1/../../../crt1.o: In function `_start': init.c:(.text+0x18): undefined reference to `main' /home/rmason/Programming/rootmac/filettEHAm.o: In function `fitCaMnMixing(int)': filettEHAm.cxx:(.text+0xfa3): undefined reference to `TLinearFitter::TLinearFitter()' collect2: ld returned 1 exit status
*** Interpreter error recovered ***

If someone can see what I have done wrong I'd appreciate the help.

Thanks,
Roger
