What is the command line to install mongodb?

Question

I'd like to call a C++ function, and the function has another function as callback function.

While in Objective-C, this is how I do:

cpp.h

typedef void (* FRAME_CALLBACK) (unsigned long, unsigned char *, unsigned long, long, long , VIDEO_B2_FRAME *);

Handle MOpen( void );

void MSetFrameCallback( Handle h, unsigned long param, FRAME_CALLBACK fnCallback );

and then in the Objective-C code:

objc.m

Hnadle handle = MOpen();

MSetFrameCallback(handle, (id)self, frameCallback);


void frameCallback(id param, unsigned char *rawData, unsigned long dataLen, long width, long height, VIDEO_B2_FRAME *b2)
{
    ViewController *VC = (ViewController *)param;
    [VC updateFrameWithData:rawData dataLen:dataLen width:width height:height];
}

But how should I do when this thing in the Swift code? I can't figure it out.

I know if I want to use ObjC or C++ Class or function that I should create a bridging file. In that situation, it works fine, but the scenario above I have no idea.

Solution 1

You cannot install mongodb using:

apt-get install mongo

You need to execute following command to install mongodb on linux:

sudo apt-get install mongodb-server

Solution 2

To install mongodb run the commands:

sudo sh -c "echo 'deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen' >> /etc/apt/sources.list"
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv 7F0CEB10
sudo apt-get update
sudo apt-get install mongodb-10gen

To test connection (wait at least 15 seconds to let the db start up), run the command below.

mongo

If the command exits with a error about not being able to connect, then reboot, and log back in as the admin user.

Sometimes MongoDB fails to create a network socket when it is started immediately after installation. It should automatically start

Are you using Ubuntu 12.04? Mongodb is a package in Ubuntu 12.10, not 12.04: packages.ubuntu.com/…

Follow the proper instructions mentioned at docs.mongodb.org. Seems like you have skipped added/updated source.
