Documentation is generated for every new build. I want to automate the process of comparing the new pdf with the old one and outputting the differences onto a text or image file. I also have the option of comparing large HTML folders or chm files(which is complicated as they are compiled files). How should I go about doing this? (I am looking for freeware Python tools)
I have looked into pdf-diff, a Python tool that does exactly what I want. But since I am working on a windows machine with no visual studio, when I try to install it using pip, I get the error "Unable to find vcvarsall.bat".
I feel like I have done my level best to search for an answer for this but, admittedly, maybe I am not using the correct search keys.
I am building a Linux kernel using Yocto and I can see that adding lines IMAGE_INSTALL_append to local.conf, followed my the additional images that you want to include is the way that you include things like connman, dropbear, etc. That's fine.
What I want to do is include an image of the application that I have written. Let's call it HelloWorld.exe and I would like it to be tucked into it's own directory (MyHello) along with a sub-directory and the sub-directory also contains some files that are necessary for the operation of HelloWorld.
I'm sure that there are different ways of doing this but I just need one. I need to know:
Where do I position my HelloWorld.exe and its attendant files and subdirectories on my Ubuntu system where they will be picked up during the build and included in the image?
How do I alter local.conf to ensure that the final image will include my application and its support files and directories where I need it to be on the target?
Thank you. Mark
I believe it gets a bit complicated in Yocto:
You need to create your own layer. Let's say meta-hello. This folder needs to in the same place as all your other meta layers and also where your poky directory is.
You need to enable that layer in your bblayers.conf file. For that you can use bitbake-layers add-layer /path/to/meta-hello
Now within your meta-hello create a recipe in a folder recipes-hello/hello
your hello.bb file is within the above mentioned folder and your can decide to use either automake, makefile or compile it accordingly using the Dev Manual Here
Once that is done, in your BUILD dir perform bitbake hello and this will compile and provide errors if any. Resolve them and once it compiles successfully, add IMAGE_INSTALL_append = " hello" in the local.conf file.
This is one way of doing it. Another one is a bit complex using the ADT Yocto Workflow
Sorry to say there is no easier way around this as Yocto does have a steep learning and development curve.
Practical Example
You can look at this blog post by Boundary Devices which creates a simple daemonize automake example. You can find it on GitHub too.

I m trying to create a python project in Atom IDE. I downloaded and installed Atom and also some package like project_manager.
I am finding it extremely hard to get going.
My project would have a few python files in the code folder. Some data files in the data folder, etc.
How do I start this in Python. I goggled this as well but still finding it difficult.
P.S. I know how to create python files and run them using IDLE. Want to do my work in a more structured manner by creating a project and then being able to compile and run my files fast and easily.

I write project where I need to identify certain file formats.
For some formats I have found signatures that I use for identifying easily (mp3, ogg), with another formats I have a big problem (like MPEG ADTS) - I just cannot find what kind of signature can be used for it.
I found out that File utility for Linux environment can do it.
I tried to search it in source code, but I've found nothing.
I found that file utility holds its database in magic.mgc file. But it's hold in binary form.
It looks like:
Does someone perhaps know how to find that database in plain text format?
That utility isn't a Linux-specific utility; it's the version of the UN*X file command originally written by Ian Darwin. The binary .mgc file is generated from a bunch of source files.
Your Linux distribution probably has a source code package for it; where you get that package, and how you install it, depends on which distribution you're using.
The source files from which the .mgc file was generated might also be available on your distribution without installing the source package for file; if so, you could use the file command to generate it, using the -C flag. I don't see them anywhere obvious on my Ubuntu 12.04 virtual machine, so that might require some other package to be installed (file itself is installed). (On OS X, they're in the directory /usr/share/file/magic.)
Alternatively, you could download the standard version of that file (which might have been modified by your distribution, so you might not want that version) and modify and build it.
Note that, on some versions of UN*X systems, the bulk of the work done by the file command is done in library routines in the "libmagic" library; see whether your distribution has that or can install it (try, for example, man libmagic) and whether it can do the job for you.
I am having problem with implementing LibSVM to MATLAB.
I am using MATLAB R2009a (I also have the latest version, R2012b, but I dont use that one)
I downloaded LibSVM package, libsvm-3.14 to my Windows 7 PC, which MATLAB and OCTAVE interface come together.
I extracted the folder I downloaded. Which, below, you can see the printscreen of what the folder has in.
Where should I put my libsvm-3.14 extracted folder ? Should I put it under "bin" folder of my MATLAB installed in the directory?
C:\Program Files\MATLAB\R2009a\bin
I did that, however, it didn't work out. I will be grateful if you help me clearly. I just read README file, but it's not clear to understand and there is no other instructions online on the internet.
For the time being, it does not matter where you put that folder. You'll have to compile the Matlab-MEX files, from the source code that resides in the matlab subfolder of your extracted libsvm package.
Below, I will call the libsvm-3.14 (for example: C:\libsvm-3.14) extracted folder ROOT (so replace ROOT wilth C:\libsvm-3.14 below).
So, fire up Matlab and, then, at its command prompt, type:
cd ROOT
cd matlab
make
Now, in the ROOT/matlab folder, you should have obtained two MEX files (with the .mexw32 or .mexw64 extension). These are the files that you will use from now on. You can discard the rest, except those files (and, maybe, some other generated libraries).
According to the Makefile (that is ROOT/matlab/make.m), the MEX files are called svmtrain and svmpredic (+ the extension).
So, next step would be to create a subfolder called libsvm/ under your's Matlab/toolbox folder, copy the two MEX files therein and, then, add that libsvm/ folder to the Matlab Path (not the Path of your system, but of your Matlab installation).
Then, by typing:
svmtrain
and
svmpredict
you should have the help (usage) of these two functions.
With the aid of #axeoth, here is the solution. I followed instruction files in matlab subfolder of extracted libsvm package. I downloaded and installed Microsoft Visual Studio 2010 and wrote 'mex -setup' on command window of MATLAB to choose a suitable compiler for mex (I use MATLAB R2012b in 32-bit PC, so I found supported compilers in this link http://www.mathworks.com/support/compilers/R2012b/win64.html) After then, I followed #axeoth's instructions. I changed the name of the folder to ROOT and moved it to Documents/MATLAB. I started MATLAB and on command window, I wrote these below "one by one"
>> cd C:\Users\HUstat\Documents\MATLAB\ROOT\matlab
>> cd matlab
>> make
then I copied everything obtained in ROOT/matlab subfolder. I created a new folder named libsvm under MATLAB/toolbox folder and pasted everything there. and then, I added that libsvm/ folder to the Matlab Path by using "Set Path" button on MATLAB R2012b. After then I wrote "svmtrain" and "svmpredict" so I got the helps of these two commands.
For those having major compiler problems I thought I'd leave some extra information on the subject of installing compilers. This was a frustrating problem I had an ended up contacted MATLAB for help. I would have commented in the above posts but I do not have enough "rep" so here it is:
I was unable to install Microsoft Windows SDK 7.1, whether via Microsoft Visual Studio 2010 or otherwise. I found out that this was because I had a certain version of Microsoft Visual installed (version 10.0.04... was the cause of the problem for me). The work around was to uninstall Visual, install SDK 7.1 independently and then re-install Visual after. The process is written up in greater detail in the link below:
http://www.mathworks.com/matlabcentral/answers/95039-why-does-the-sdk-7-1-installation-fail-with-an-installation-failed-message-on-my-windows-system
It may also be that you have the compiler installed but that it wasn't recognised until MATLAB "found" it. This happened to me after the re-install. To check if you have the correct compiler and "find" it run mex.getCompilerConfigurations('Any','Installed') to get a full list. Then do mex -setup using the SDK 7.1 choosing the C/C++ version over FORTRAN.
I know the question is answered already but hopefully this may help someone the same predicament I had.
