Hi

I have compiled many times espresso-4.0.5 with the suggested patched files for elecron-phonon calculation in the tutorial section, but at the end of making espresso I have faced following error while without these patches I make successfully:

../PH/libph.a(allocate_phq.o): In function `allocate_phq_':

make[1]: *** [d3.x] Error 1
make[1]: Leaving directory `/home/softs/espresso-4.0.5/D3'
make: *** [d3] Error 2

How can I overcome the error?
Moreover, in the tutorial of el_ph you said "The procedure to get the el-ph databases ndb.elph_gkkp_fragment will be described in this section shortly ", but every day I checked I find nothing. Would you please help me how to make the procedure?

Thanks a lot
