Setting up cppcheck

To install pre-built cppcheck:

sudo apt-get update
sudo apt-get install cppcheck

In case, you want to use latest cppcheck, download and build it from the source code

tar zxvf 2.1.tar.gz
cd cppcheck-2.1
mkdir build
cd build
cmake ..

P.S: In case you are interested for cppcheck GUI use cmake -DBUILD_GUI=ON ..

sudo make install

Once installation is complete.

which cppcheck

cppcheck --version
Cppcheck 2.1

Build your cpp project with cmake and pass on an extra parameter -DCMAKE_EXPORT_COMPILE_COMMANDS=TRUE to cmake. It will produceĀ  compile_commands.json file in your build folder for the project.

Execute cppcheck -p </path/to/folder/having/compile_command.json>.

To use it in VSCode add following to the tasks.json

    "label": "Run cppCheck",
    "command": "/usr/local/bin/cppcheck",
    "args": [
    "problemMatcher": "$gcc",

symlinks in virtualbox

If you are using Windows in Virtualbox ontop of Linux based (i.e: Ubuntu) machine, you might have seen this problem that accessing symlinks in windows does not work. Instead of showing contents after resolving Linux symlinks, you will end up with “Protocol error”.

This error can be fixed using vBoxManage by setting a boolean property (SharedFoldersEnableSymlinksCreate) against each folder shared with VirtualBox based machine.

VBoxManage setextradata <VirtualMachineName> VBoxInternal2/SharedFoldersEnableSymlinksCreate/<SharedFolderName> 1

After executing above command, verify your change with following:

VBoxManage getextradata <VirtualMachineName> enumerate
