Minuit2 library missing

ROOT
1

Hello,
I am trying to compile a code which uses Minuit2 library. I get this problem:

/usr/bin/ld: cannot find -lMinuit2 collect2: ld returned 1 exit status
Minuit2 is in my root distribution, but when I compile root it does not compile the Minuit2 library:
The code is in:

$ROOTSYS/math/minuit2/

I have downloaded the code from: seal.web.cern.ch/seal/MathLibs/M … it2.tar.gz
then configure --prefix=$ROOTSYS ;make;make install but when I try to compile my code I get:

/software/at3/root/root-5.30.04_slc57_gcc4.1.2-51_x86-64_PROOF/lib/libMinuit2.so: undefined reference to `GOMP_parallel_start' /software/at3/root/root-5.30.04_slc57_gcc4.1.2-51_x86-64_PROOF/lib/libMinuit2.so: undefined reference to `omp_get_thread_num' /software/at3/root/root-5.30.04_slc57_gcc4.1.2-51_x86-64_PROOF/lib/libMinuit2.so: undefined reference to `GOMP_parallel_end' /software/at3/root/root-5.30.04_slc57_gcc4.1.2-51_x86-64_PROOF/lib/libMinuit2.so: undefined reference to `omp_get_num_threads' collect2: ld returned 1 exit status make: *** [.o/src/main.bin] Error 1

Is there a way to compile and obtain the Minuit2 library from the root distribution?
Thanks so much!

Minuit2 is distributed with ROOT but not built by default.
You need to pass ‘–enable-minuit2’ to ‘./configure’ .
Check also ‘./configure --help’.
Also make sure that it appears among the list of enabled modules printed by ‘configure’ at the end.
