Error 2 installing plumed in ubuntu 18.03

[Ángel Piñeiro]

Hi

I am trying to install plumed 2.7.1 in ubuntu 18.03. The compilation seems to work fine with the following options:

./configure --prefix=/home/fangel/plumed271 --disable-external-blas --disable-external-lapack

I decided to disable external blas and lapack because I thought they could cause some problem but the error is the same without these options. The error comes when trying to "make":

It seems some error with fftw. I reinstalled it but the error persists. Any help?

Hi,

sorry I saw this with some delay. You should make sure to install fftw *shared* libraries. Alternatively, tell plumed not to use fftw (--disable-fftw)
