[QE-users] configure error: Could not find required libxc library.

[Fabrizio Ferrari]

Hi Jibiao,
please do this:

1-configure without any libxc flag;
2-go to the make.inc file in the main folder and add the various flags to
DFLAGS, IFLAGS and LD_LIBS by following the comments inside;
3-compile as usual.

This should answer to both your emails
Best regards,
Fabrizio
