Dear all;
I run an execute file named "A" gets it's input from a text file "B.inp"
but I face this error:
A < B.inp
: error while loading shared libraries: libquadmath.so.0: cannot open shared object file: No such file or directory

I've downloaded libquadmath and when I want to install it ,the other error said I don't have libgc package!!! but I have libgc!! is it because of existing two different repository that it can't share their information?
my operating system is Centos6;
what shall I do?
Thanks for your attention

I have CentOS 7 64 bit. I have installed open-vm-tools on it.
I have installed vmplayer using
Code:

./VMware-Player-6.0.1-1379776.x86_64.bundle

Now when I try to open vmplayer on it, it does not load 'Virtual Network Device'
and shows error in terminal
Code:

Failed to build vmnet.  Failed to execute the build command.

When I check status of vmware, it shows
Code:

Module vmnet not loaded

If I try to run
Code:

vmware-modconfig --console --install-all

It gives me following error.
Code:

make: Leaving directory `/tmp/modconfig-2NfFeS/vmnet-only'

I am not able to open VMplayer, please help me to open it.

Thanks

hello Experts!
need some help here with python FTP. so what i'm trying to do is, from a linux machine, ill be sending over a python script to a windows machine via python ftp. that works fine with no problem. now, i want to execute that python script i sent remotely. im having trouble with that. here's my code to just execute the script:

p.s : please dont suggest other options such as python paramiko due to many network security reasons

Code:

ftp = ftplib.FTP("windows machine name")
ftp.login("username", "password")
ftp.cwd("where\\python\\script\\is kept\\")

ftp.sendcmd("python myscript.py")

but looks like it doesn't recognize that command. how do i accomplish this please?
