problems in installing plumed2.5.1 in Ubuntu 18.04

[Raffaela Cab]

HI,

I am having problems in installing plumed 2.5.1 in Ubuntu 18.

I am following the instructions from the link:

The steps with

1. ./configure --prefix=/usr/local
2. make -j 4
3. make install 

after many trials look to be succesfull. 
Unfortunately when write 
plumed 
I get the answer: 
plumed: error while loading shared libraries: libplumedkernel.so: no such file or directory. 

Can you please tell me how to proceed? 

Thank you

[Giovanni Bussi]

Check if the following file exists

/usr/local/libplumedKernel.so

(actually the K should be upper case. Did you make a mistake copying the error in the email text?)

If so, use this command

export LD_LIBRARY_PATH=/usr/local:$LD_LIBRARY_PATH

then launch the plumed executable.

Let us know if this works for you

Giovanni

Hi again,

The installation was sucessfull only after ensuring the installation of matheval was sucessfull and

including the matheval.h path into the configuration path:

sudo ./configure CPPFLAGS=-I/usr/include CC=mpicc CXX=mpicxx

Probably this link can be useful:

Thanks for asssistance.

Sorry it should have been

export LD_LIBRARY_PATH=/usr/loca/libl:$LD_LIBRARY_PATH

Anyway, good that you fixed it. thanks!

Yes. I have located the files and included in the right path.

Your suggestions were very helpful.

Thanks

Dear Raffa,

Path in export shall be /usr/local/lib

Not /usr/local
