Hello Rooters!
I have the same problem like in here, so sorry if it will be the duplicate, but solution from this link doesn’t work for me
Let’s see on my case, please:
17:04:07|bdrum@nf-100-211:Cpp>> cat testRoot.cpp
#include<TSpectrum.h>
int main() {
auto sp = new TSpectrum();
return 0;
}
17:04:10|bdrum@nf-100-211:Cpp>> g++ `root-config --glibs --cflags --libs` -lSpectrum -o run testRoot.cpp
/tmp/ccJbrONX.o: In function `main':
testRoot.cpp:(.text+0x1c): undefined reference to `TSpectrum::TSpectrum()'
testRoot.cpp:(.text+0x5a): undefined reference to `TObject::operator delete(void*)'
/tmp/ccJbrONX.o: In function `__static_initialization_and_destruction_0(int, int)':

collect2: error: ld returned 1 exit status
#as you can see here - I have libSpectrum (also I added -L flag with this path, but result was the same)

Do you have any idea how to fix it and what name of library (like -lSpectrum) for Minuit2, how can I include it?
Thanks!
