Compiling helloworld.cc

[Batman]

Dear CS users,

So I'm completely new to using ceres solver. Can some one please walk me through how to write code and how to compile it? I'm using Ubuntu 14.04 and gedit to write my code.

Thank you so much!

[Sameer Agarwal]

Have you read the tutorial?

I have read the tutorial, but I can't understand it very well.

[Sameer Agarwal]

Have you been able to build ceres following the instructions for ubuntu?

Yes I have. Now I have 2 folders saying ceres-bin and ceres-solver-1.10.0

[Sameer Agarwal]

in your ceres-bin there should be a directory called bin which should contain the helloworld binary and other example programs.

So how would I execute these programs? I'm sorry, I'm quite new to Linux

[Sameer Agarwal]

ceres-bin/bin/helloworld

will run helloworld.

That said, if you are new to linux and c++ programming, you are going to have a rough time with ceres. I recommend gaining some proficiency in both before you start using ceres.

An option is to copy the 'helloword.cc' to another folder and use cmake:

[Batman]

If I was using cmake, how would I do so? I know I should have a folder containing helloworld and CMakeLists.txt. Would I just have to type in cmake <folder_name>?

[Sameer Agarwal]

Rohit,
I suggest that you start by working your way through 

http://www.cmake.org/cmake-tutorial/

to get the cmake basics.

Didn't you compile ceres solver using cmake? That was an example. Ok, anyway, the process is always similar to:

> cd <folder_name>

> mkdir build

> cd build

> cmake ..

> make

> ./helloworld
