[dm-crypt] [cryptsetup] Develop Environment for cryptsetup

Hi all,

I am a student from Vietnam. I want to develop my cryptsetup with some new
features. But I get some problems with all source code of cryptsetup. I
don't have skill for read and understand configure and makefiles.

So, I want to ask all of you some questions:

- What IDE do you develop cryptsetup on?

- How do I debug cryptsetup?

- How do I modify Makefile, Do I need understand all content in makefiles,
configure file?

Thanks so much.

You can interface with cryptsetup in two different ways.

1. Though its binary interface.From the terminal,run "cryptsetup --help"
and "man cryptsetup" to get more info on this interface.

2. Through the library API interface,you can get more info on this
interface from this link:
http://wiki.cryptsetup.googlecode.com/git/API/index.html

Which one of the two will be more appropriate depends on your use case but
both can be used from your GUI application.

These two interface should be sufficient for you and if you are to look at
cryptsetup code,it should be only go get more insight on how to use the
library API and not to extend it as that is most likely not want you want
to do.

back your questions here

I am not one of cryptsetup developers,but i am interested to know too.In my
code that interfaces with cryptsetup library,i do not use one as kwrite(
KDE text editor ) seem to be suffient for me.C code doesnt carry massive
objects with 1000+ member functions and properties and hence a fully
fledged IDE is not really necessary.

If you use the executable,call it with "--debug" option to get more output
If you use the library,library info can be found in this link:
http://wiki.cryptsetup.googlecode.com/git/API/group__dbg.html

The full library API is at:
http://wiki.cryptsetup.googlecode.com/git/API/libcryptsetup_8h.html

cryptsetup development package from your distro package system and the only
look at "libcryptsetup.h" header file as the interface to cryptsetup to
work with.

It is also probably a good idea to look at the FAQ at:
http://code.google.com/p/cryptsetup/wiki/FrequentlyAskedQuestions
It has answers even to questions you would never though to ask even if your
life depended on you asking them :-)

Makefiles, you will need to learn how to read and write. Don't start 
with something as difficult though. Also, don't modify cryptsetup itself,
use the library and start with somethign simple. You can, for example, 
start by tryingi to understand and modify the things in the misc. 
directory.

IDE? Why would you use an IDE? I use emacs as editor, that is enough.
This is not Java, were an IDE is almost needed because there is
so much syntactic noise.

The old wy: Code-embedded debug instratctions. You may also
try DDD.

Don't go that way, see above.

Thanks all,

I think cryptsetup API is the best solution for me.
