Latex \printnomenclature doesn't work

Add to TexStudio or your favorite editor, the user command:

makeindex %.nlo -s nomencl.ist -o %.nls

And for update, compile, execute the above user command, and compile again.

Ubuntu 16 - VMWare Player 12 - GCC Not found

First solution
cd /usr/lib/vmware/modules/source 
wget https://github.com/mkubecek/vmware-host-modules/archive/player-12.5.9.zip 
unzip player-12.5.9.zip 
cd vmware-host-modules-player-12.5.9/vmmon-only/ 
make 
cd ../vmnet-only/ 
make 
cd .. 
mkdir /lib/modules/`uname -r`/misc 
cp vmmon.o /lib/modules/`uname -r`/misc/vmmon.ko 
cp vmnet.o /lib/modules/`uname -r`/misc/vmnet.ko 
depmod -a /etc/init.d/vmware restart


Second solution

mkdir ~/vmmodules #create a temp folder and copy files.
cp /usr/lib/vmware/modules/source/vmnet.tar /usr/lib/vmware/modules/source/vmmon.tar ~/vmmodules/ 
# make the modules manually 
tar -xvf vmmon.tar 
cd vmmon-only 
make 
cd .. 
sudo cp vmmon.o /lib/modules/`uname -r`/kernel/drivers/misc/vmmon.ko.gz 
tar -xvf vmnet.tar 
cd vmnet-only 
make 
cd .. 
sudo cp vmnet.o /lib/modules/`uname -r`/kernel/drivers/misc/vmnet.ko.gz 
#Then reload the modules and restart vmware service, vmplayer should works now. 
sudo depmod -a 
sudo systemctl restart vmware


Thrid solution

#install the right version of gcc
$sudo apt-get install g++-4.9 

Trick

$sudo sed 's/gcc version 5.4.0/gcc version 6.4.0/' /proc/version > /tmp/version
$sudo mount --bind /tmp/version /proc/version
$sudo vmware-modconfig --console --install-all
$sudo umount /proc/version && rm /tmp/version
