mkdir build cd build Try cmake .., if Eigen or GSL not found, manual way is cmake .. -DCMAKE_INSTALL_PREFIX=[...]/eigen-eigen-b3f3d4950030/ -DGSL_ROOT_DIR=[...] make -j

Once you have a copy of best_sampler on your device, enter the directory and open the file "makefile_defs.mk". You will need to change the pathways in this file to match the location of the best_sampler directory on your device and the locations of eigen3 and gsl.

Now enter best_sampler/software and type

make install

If this is successful, exit the software directory and enter best_sampler/run. Then type

make sampler
./sampler

The output should be

will read res info from ../local/resinfo/pdg-SMASH.dat
NResonances:493
will read decay info from ../local/resinfo/pdg-SMASH.dat
opening ../local/include/surface_2D.dat
Exiting ReadHyper() happily, TotalVolume=7170.271412, nelements=43461
nparts=503589	totvol=999999.999911	nparts/totvol=0.503589	nhad=0.503943
YIPPEE!!!!! We made it all the way through!

There is a file in the run directory called parameters.dat. You can change the file from which the sampler reads resonance, decay, and hyper-cell information by changing the macros RESONANCES_INFO_FILE, RESONANCES_DECAYS_FILE, and HYPER_INFO_FILE respectively within parameters.dat to different file pathways. Bear in mind that the file reading is set up specifically for the format of the current resonance info and hyper-cell files. The sampler also creates different sampler objects depending on the value of the sigma field and the temperature--you can change the values of both of these in this same file; the variables for these are fairly self-explanatory.
