compillation problem in Cygwin environment

[nulakani]

Dear Sir
Greetings

Recently, i have tried the yambo installation on a cygwin based linux environment. first i did configuration using 1) ./configure command and next i have issued 2) make all. The complilation went on well except the yambo linking. I have serched the fouram for the possible clarification for this kind of errors and unable to find the same. I have attached the config.log file for your persual. This is the error message on the machine

---------------------------------------------------------------------------------------------

I have also tried with the older version Yambo-3.4.1. It has installed witout any error.

Dear Venkat,
from your config.log file I can see you configured specifying a libxc path:

Code: Select all

$ ./configure --with-libxc-path=/cygdrive/f/NNV/SOFT/YM/lib/libxc/libxc-y2.0.3/ x86_64

and it looks that yambo has having problem linking with your xc libs.
After a make clean_all, reconfigure without specifying the libxc path:

Code: Select all

./configure

yambo will download the needed libraries and compile them.

Best,

Daniele
