Yambo Community Forum

Hi,
everybody, I am a new yambo user. And recently I try to compile the yambo code. But I always failed. The process I complied as follows:

./configure --prefix=/home/supercaq/yambo-3 FC=/opt/openmpi/bin/mpif90 F77=/opt/openmpi/bin/mpif77 CC=/opt/openmpi/bin/mpicc

and then errors came up:
checking for Fortran libraries of /opt/openmpi/bin/mpif90... -L/opt/openmpi/lib -L/opt/intel/composer_xe_2011_sp1.7.256/compiler/lib/intel64 -L/usr/lib/gcc/x86_64-redhat-linux/4.4.5 -L/usr/lib/gcc/x86_64-redhat-linux/4.4.5/../../../../lib64 -L/lib/../lib64 -L/usr/lib/../lib64 -L/usr/lib/gcc/x86_64-redhat-linux/4.4.5/../../.. -L/lib64 -L/lib -L/usr/lib64 -L/usr/lib -lmpichf90nc -lmpich -lpthread -lrt -lifport -lifcore -limf -lsvml -lm -lipgo -lirc -lirc_s -ldl

checking if precompiler works on C source... yes
checking if precompiler works on F90 source... no

The version of yambo is yambo-3.2.4-r.855. the compiler is ifort and the version of openmpi is openmpi-1.4.4

How can I solve such problem ? any suggestion is appreciated ! thank you! By the way, the config.log file was attached.

Dear Aqing,
please fill your signature complete of affiliation, this is a rule of the forum.
It looks you are having precompiler problems. Try to set:
./configure FC=ifort F77=ifort CC=icc CPP=gcc --enable-msgs-comps
and look if it works, after typing make clean.
You can also look at other thread on this topic in the forum, and may be
you can find useful information there.

Cheers,
Daniele

Dear Daniele,
Thank you for reply. I recompiled the yambo code again following your suggestions again listed below:
$ make clean
$./configure FC=ifort F77=ifort CC=icc CPP=gcc --enable-msgs-comps

But, another errors came up.
checking for icc option to accept ISO C89... none needed
checking how to run the C preprocessor... gcc
configure: error: in `/home/supercaq/yambo-3.2.4-r.855':
configure: error: C preprocessor "gcc" fails sanity check
See `config.log' for more details
[supercaq@localhost yambo-3.2.4-r.855]$

How to solve it? can you help me again ? The config.log file was also attached.

I am completing my signature. thank you !

Hallo

try to leave out the CPP. If still not working try with "icc -E -ansi"

Best
