Dear all
I am trying to compile Yambo-3.2.4-r.855. My configure was as:

./configure --exec-prefix=/home/User/ProgramFiles/Yambo --prefix=/home/User/ProgramFiles/Yambo/LIBS --with-fftw=/usr/local/lib/libfftw3.a --with-mpi=/home/User/ProgramFiles/MPICH/lib/libmpich.a --with-libxc-lib=/home/User/ProgramFiles/LibXC/lib --with-libxc-include=/home/User/ProgramFiles/LibXC/include --with-p2y=4.0 --with-iotk=/home/User/ProgramFiles/Quantum-ESPRESSO/iotk FC=mpif90 LDFLAGS=-nofor_main

Then I obtained the configure result as:

#
# [VER] 3.2.4 r.855
#
# [SYS] linux@x86_64
# [SRC] /home/User/Download/yambo-3.2.4-r.855
# [BIN] /home/User/ProgramFiles/Yambo/LIBS/bin
# [FFT] FFTW Fast Fourier transform
#
# [ ] Double precision
# [X] Redundant compilation
# [X] MPI
# [X] PW (4.0) support
# [ ] ETSF I/O support
# [ ] SCALAPACK
# [X] LibXC
# [ ] NETCDF/HDF5/Large Files
# [XX ] Built-in BLAS/LAPACK/LOCAL
#
# [ CPP ] gcc -E -P
# [ C ] gcc -g -O2 -D_C_US -D_FORTRAN_US
# [MPICC] mpicc -g -O2 -D_C_US -D_FORTRAN_US
# [ F90 ] mpif90 -O
# [MPIF ] mpif90 -O
# [ F77 ] mpif90 -O
# [Cmain]
# [NoOpt] -O0
#
# [ MAKE ] make
# [EDITOR] vim
#

Finally, during compiling by make yambo, an error occurred:

make[1]: Entering directory `/home/User/Download/yambo-3.2.4-r.855/driver'
yambo_driver.F
driver.o: In function `main':

make[1]: *** [yambo] Error 1
make[1]: Leaving directory `/home/User/Download/yambo-3.2.4-r.855/driver'
make: *** [yambo] Error 2

I have checked the post: viewtopic.php?f=1&t=313, but I found I have used the parameter LDFLAGS=-nofor_main.
How could I solve this problem?
Any suggestion will be welcome.

Dear GAO Zhe

if your mpif90 is in the your path try to configure yambo with the options:

./configure FC=ifort F77=ifort

Thank you, Claudio, for your kindly and quickly reply.
I tried to set FC=ifort, it works well. However, I'm eager to know whether I can use MPI once I compiled Yambo with FC=ifort?
I am using MPICH2, which was compiled by ifort.
Furthermore question. After compile by "make all", there were only four files, a2y, p2y, yambo, and ??(I forgot the name, sorry), have been copied to ~/ProgramFiles/Yambo/bin, which I setted as --prefix=~/ProgramFiles/Yambo/LIBS --exec-prefix=~/ProgramFiles/Yambo. And there was no rule for "make install". May I delete the directory ~/Download/yambo-3.2.4-r.855 and just use the four files?

check after the configure if yambo found your MPI enviroment

# [ ] Double precision

the MPI boxed has to be ticked

yes, you just need the executables: yambo, a2y, p2y, ypp
