I'm trying to compilate a C program(Appendix C of this pdf) using libxml2 in Eclipse.
Looks like the program recognize the library but not the functions of the headers(i.e. recognize < xmlstring.h > but not the function xmlStrcmp)
This is a screenshot of my eclipse plattform: http://goo.gl/kOdvZB
(This is my first post so I dont have reputation to post images, sorry u.u):
What could be the problem here?
What am I doing wrong?
I don't know what to do.
Thanks
Did you remember to link against the library? The "undefined reference" error is a linker error which means that the symbol you requested doesn't exist.

I am trying to compile c code in c++ and I get this error!
Illegal character(0x1)، Why this error occurred?
May be you have copied the code from the Internet!
Try typing it.
It will improve your coding ability.
Probably there really is a funny character in your file, maybe one your editor doesn't render.
Try using a hex dump program to see each byte of the file rather than an editor. You may find that there's more characters than you realize in your file.
When I started to learn C ( with an old borland in the late 90s ) I wish somebody would have told me this advice: don't use Borland. Use linux and gcc and you'll have a much better time. Now this might not be true of everyone, but it does support windows binaries too and sure would have felt better to me when I was just trying to learn ANSI C.

I'm trying to create a C program whose goal is to enable_irq and disable_irq.I have include linux/irq.h like that
#include <linux/irq.h>
And when I compile :
gcc myProgram.c -o myExecutable
I have the error : fatal error : linux/irq.h no file or folder find
What package I have to install? I'm on archLinux.
You cannot disable IRQs from a userspace application. Those functions are only available within the kernel.

I'm having trouble with conio.h, I use Eclipse Standard but when I try to use clrscr, textcolor, textbackground, they all remain unresolved please advise me on alternatives or how I can get these to work. Thx.
conio.h is DOS (or turbo-c) specific extension. It defines functions available in in that environment. Don't think its available in standard VC++ or gcc libraries now.
Make sure the .lib are available on the path.

I'm trying to understand why should I dereference functions while making a self-modifying code in C.
Even though it works this way, I would like to know why!
Here's an example of what I was dealing with:

I asked the guy from the blog but he never answered :(

I'm rather new to C++/CX, and right now have an old C project which I need to port into C++/CX.
The output are flushed into text-file or standard output, but it's not that important right now since I can just take them into the Message Dialog there.
My question is that, do you have any tips for porting this project?
I just tried to copy a C file into CPP but failed to compile.
I mean, do I need to wrap the old functions into some kind of Class structure now?
Thanks in advance!
For the differences between C and C++, a starting point is David Tribble's "C99 vs C++98". Without any more details (original C environment, current C++ environment, some details on exact error messages) it is next to impossible to answer the question.
