installing Multifn on Ubuntu 20.04.2 LTS

Hello:

I'm trying to install Multiwfn in Ubuntu 20.04.2 LTS;

-When I use the "sudo apt-get install libmotif4" command it says that the package is indisposable. It suggest to me the following packages:

libxm4 libuil4 libmrm4 libmotif-common

Which one of these works well whit Multiwfn?

-I have modified the bashrc file with;

export KMP_STACKSIZE=200M
ulimit -s unlimited
export Multiwfnpath=/sob/Multiwfn_3.6_bin_Linux
export PATH=$PATH:/sob/Multiwfn_3.6_bin_Linux

but when I run the "chmod +x /sob/Multiwfn_3.6_bin_Linux/Multiwfn" command it says that the file or path does not exist.

How I can solve that?

Thank you in advance.

Re: installing Multifn on Ubuntu 20.04.2 LTS

Please try to install libxm4 and libmotif-common first.

You should replace the paths in the manual by actual path in your machine.

Re: installing Multifn on Ubuntu 20.04.2 LTS

Hello:

Thanks for your reply.

I have installed libxm4 and libmotif-common.

In the bashrc file I have set:

export Multiwfnpath=/home/juandi/Escritorio/Multiwfn_3.8_dev_bin_Linux
export PATH=$PATH:/home/juandi/Escritorio/Multiwfn_3.8_dev_bin_Linux

Then, I run the "chmod +x /home/juandi/Escritorio/Multiwfn_3.6_bin_Linux/Multiwfn" comand.

Now, ?which part of the settins.ini file I have to modify to be able to boot up Multiwfn?

Thank you in advance.

Re: installing Multifn on Ubuntu 20.04.2 LTS

You can simply run Multiwfn now. settings.ini is not necessarily to be modified before booting up Multiwfn. However, it is recommended to set "nthreads" in this file to actual number of CPU physical cores.

chmod: cannot access '/home/downloads/Multiwfn_3.8_dev_src_Linux': No such file or directory

However, I don't know which procedure I did wrong.

$ export Multiwfnpath=/home/downloads/Multiwfn_3.8_dev_bin_Linux
$ export PATH=$PATH:/home/downloads/Multiwfn_3.8_dev_bin_Linux
$ chmod +x /home/downloads/Multiwfn_3.8_dev_bin_Linux
chmod: cannot access '/home/downloads/Multiwfn_3.8_dev_bin_Linux': No such file or directory

I also downloaded MultiWFn_3.8_dev_bin_Linux.zip

The same happened

Re: installing Multifn on Ubuntu 20.04.2 LTS

Perhaps you should run

chmod +x /home/downloads/Multiwfn_3.8_dev_bin_Linux/Multiwfn

"/home/downloads/Multiwfn_3.8_dev_bin_Linux/" is folder, while "/home/downloads/Multiwfn_3.8_dev_bin_Linux/Multiwfn" is executable file.
