Programming :: Use Ntfs-3g Library In C++?

Mar 30, 2010

I am trying to write a program that can get the times from files on a NTFS drive in Linux using the ntfs-3g library. I have installed the development libraries and source on my Fedora 10 machine. I can find the headers in the /usr/include/ntfs-3g directory but when i try and compile my program I am getting an undefind reference to ntfs_mount() call. I have the following in my link string

g++ -L/lib -o ProgramName -lpthread -lntfs-3g

I did a pkg-config --cflags --libs libntfs-3g and it said all i needed was the -L/lib -lpthread and -lntfs-3g.

Programming :: SDL Static Library - Shared Library ?

Apr 7, 2009

I'm reading about shared, static, and dynamic libraries. What is SDL? Is it static, shared, or dynamic?

I always thought a library would be a lot of .h and .cpp files compiled separately into .o files and then if you compiled your own program you could use the -l parameter to link the library and it was all compiled together. Now I'm not so sure.

I don't even see any SDL .cpp files in my system anywhere. All I have are lots of SDL .h files in /usr/include/SDL and I don't really understand the code in them.

I'm making a wild guess here: SDL is a shared library. SDL itself is NOT compiled into my program, therefore SDL must be on any system my program tries to run on. When I compile and link SDL all it needs is the header files to know what SDL function and objects it can use. And then on every system it uses an already compiled SDL shared library thingy somewhere.

So... where is that part of SDL? All I can find are header files.

I'm thinking the advantage of shared libraries is that someone could say update SDL on their own system and take advantage of the new features without having to download new executables with the new version of SDL compiled into them for every program that uses SDL.

So if I'm making an editor and a game engine and they both use a lot of the same .cpp and .h files that I wrote and I'm tired of updating one and then the other and I need to turn them into a library, then a shared library might be kind of a silly solution. I could just make a static library. Right? Because it's not SDL. Nobody else is ever going to use this library.

Debian Multimedia :: Adding Folders On NTFS Drives To Music Library?

Dec 22, 2010

I have my music library stored on an NTFS hard drive, from when I used to run Windows. The drive mounts successfully in Linux and I can manually play tracks from it, but I don't seem to be able to point Rhythmbox or Banshee to the drive or to folders on the driveto add them to their libraries. Is there any way to do this? Otherwise I'll have to begin the very long process of juggling files between hard drives until I have enough free space to format one of them

Programming :: Library Dependencies And G++

Apr 18, 2010

How to make simple games (snake, pong... nothing too fancy). I have completed making snake and now want to be able to distribute it. I built it using C++ and wxWidgets so it would be multi-platform. I'm able to compile it and run it in both Windows and Ubuntu using g++. In windows, I was able to distribute it by putting a *.dll file in the same folder as the executable. However in Linux, I don't understand what I need to do so that it would run on any installation of Ubuntu out of the "box". When I build it and try to run it in a different installation of Ubuntu (which has g++) it gives me an error saying that a particular library file was not found and Getlibs fails to find that library file.

Is there a way to build a project with G++ so that all the dependencies are either packaged in the executables or copied into the folder....?

Programming :: Definitions For C Library Functions ?

Apr 24, 2010

Where are the definitions for C library functions located? It was just recently that I realized that header files don't actually define any functions, they merely include their prototypes.

For instance, stdio.h includes the following line:

Code:

This just means that the definition of printf() is located in another file. What file? Is there some kind of default shared object file that is automatically included during compilation?

Programming :: Location Of - Gnu - C++ Standard Library

Where is the location of the header files for the c++ standard library?

I assume that they were installed by gnu g++, please correct me if i'm wrong.

I'm running ubuntu 10.04 with g++ 4.4.

I looked in /usr/lib/gcc/i486-linux-gnu/4.4/include, but this directory contains only the following:

Code:

Which doesnt seem to include the really basic things like iostream, for example.

Where can I take a look at the header files for these standard c++ libraries?

Programming :: Compiling The Library + Application?

Nov 28, 2010

I'm trying to learn how to cross-compile libraries (static and shared) and executables for the Blackfin + uClinux environment.At this point, I can successfully compile a stand-alone "Hello, world" but fail when trying to add a (static) library to the mix.Here's the source code I wrote:

Code:

#========== bar.h
void mytestfunc(void);
#========== bar.c
#include <stdio.h>

[code]...

Googling for this returns talks about "name mangling", but I don't know if this is what it is, and how to change the source/command to solve it.

Programming :: Can't Load Shared Library (but It's Right There!)?

Feb 15, 2011

I have visited these boards a few times, but never posted. Here's my problem: I was given the source to a program and asked to get it running on a 64-bit Debian 2.6.26 machine. Currently it is working on 2 64-bit OpenSUSE machines.

The application uses TCL TK for a GUI and everything compiles just fine; however, on startup, the user must enter one of three possible modules to load; when attempting to load these modules (tcl 'load' function), I receive this error:

Code:
Error in startup script: couldn't load file "../Build/libMpf.so": libTransReaders.so: cannot open shared object file: No such file or directory
while executing
"load ../Build/libMpf.so Mpf"
("eval" body line 1)
invoked from within
"eval load ../Build/${px}${i}${sx} $i"

Programming :: Debug Library Source In GDB/DDD?

Aug 25, 2009

is there a way to debug my library files from DDD? Basically a way to pass the paths to DDD so I can view the source etc. I'm having a segmentation nightmare, which only crops up about every 10 or so starts, I know it's in one file in a library. I could move the source file into my general code to debug, but am sure there's a way in DDD.

Programming :: Compiling The Poppler Pdf Library?

Jul 29, 2011

I am trying to use the QT4 frontend of poppler library in my application so I need to compile the library.In its main directory ./configure can be run but I got

Code:

checking which font configuration to use... fontconfig
checking for FONTCONFIG... no
configure: error: Package requirements (fontconfig >= 2.0.0) were not met:
No package 'fontconfig' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables FONTCONFIG_CFLAGS
and FONTCONFIG_LIBS to avoid the need to call pkg-config.See the pkg-config man page for more details.

I have fontconfig installed (ubuntu):

2.8.0-2.1ubuntu3 (fontconfig)

However I have no idea where those flags are and what to set them to.

Programming :: Force Repetitive Library Search Using G++ V3.2 On 3.9?

I have an application with a complex binary build procedure which links against 30+ application library archives and an array of system library archives. The problem I'm having is the link ordering. Is there a way to tell the g++ linker to keep searching the libraries for unresolved references, regardless of order, instead of rearranging the order the archives are listed on the command line for a one-time-pass? I'm using g++ 3.2.3 on a Linux AS v3update6 machine.
