HLLib - NemPosted: May 23rd, 2005 - 6:32:20 pm
About:

HLLib is a package library for Half-Life that abstracts several package formats and provides a simple interface for all of them. HLLib is written in native C++ but exposes both a C and C++ interface which can be used in any C or C++ application (additional languages may also use the library with standard C imports). HLLib works natively in both Windows (x86 and x64) and Linux. BSP, GCF, NCF, PAK, VPK, WAD, XZP and uncompressed ZIP package formats are supported.

HLLib is an open source library licensed under the LGPL. It comes with the source code and binaries necessary to use it. An example application called HLExtract, which is licensed under the GPL, is also included. HLExtract is a command line utility written in C that can load all HLLib supported packages and extract multiple items from them while maintaining their directory structure. Also included is a C# HLExtract port called HLExtract.Net.

Download: GridMount:

A MacFUSE file system handler called GridMount is available for those looking to run HLLib on a Mac.

Java Wrapper:

A Java wrapper is available for those looking to use HLLib in Java. It can be found on SourceForge.

Well, this looks like a pretty spiffy library... but you should create dsw and dsp files for people who are jacked with VC++6. But I'm not one of them (I have neither--I compile them all by hand using .NET toolkit and lots of microsoft SDK's happy).

2. NemPosted: Sep 5th, 2004 - 8:37:03 am

If I had Visual Studio 6.0 I would have but I don't. That said, there is no reason to need to compile the library (as the binaries are included) unless you want to make changes to it and if a Visual Studio 6.0 user does want to make changes, it is not to hard for them to convert (or recreate) the project files.

Visual Studio 6.0 users might also be interested in the free build of Visual C++ .NET 2005 Express Beta from Microsoft.

Will I be able to use HLLib in a C# Express project?

4. NemPosted: Dec 31st, 2005 - 3:26:48 pm
If you wrote a C++ .NET wrapper.

5. VarsityPosted: Jan 4th, 2006 - 10:09:02 am
.NET allows different languages to coexsist in the same project, or something along those lines. Wouldn't simply compiling HLLib into C++ .NET do the trick?

What is a C++ .NET wrapper and how can i do it? apple

7. NemModified: Jan 4th, 2006 - 3:04:05 pm
C++ .NET is an extension of C++ and is managed in the same way that C# and VB code is managed. However, C++ .NET still allows for native C++ code. If you want to use native C++ in a .NET language other than C++ .NET you need to write a managed class that has the same structure as its equivalent unmanaged class that performs the necessary conversions, eg:

Code:

// Original class
class CExample
{
public:
CExample()
{
string = 0;
}

~CExample()
{
delete []string;
}

char *GetString()
{
return string;
}

void SetString(const char *newString)
{
delete []string;
string = new char[strlen(newString) + 1];
strcpy(string, newString);
}

private:
char *string;
};

using namespace System::Runtime::InteropServices;

// Wrapper class
__gc class Example
{
public:
System::String *GetString()
{
return new System::String(example.GetString());
}

void SetString(System::String *newString)
{
char *string = (char *)(Marshal::StringToHGlobalAnsi(newString)).ToPointer();
example.SetString(string);
Marshal::FreeHGlobal((System::IntPtr)string);
}

private:
CExample example;
};

However, I will be completing HLLib 2.0 soon which will have a C wrapper which you should be able to directly import into any C# project (in fact almost any project in any language).

Oh thats great :D

When I use HLExtract to defrag my GCF's I get this error on one of them:



Is there anything I can do to fix this?

Oh and all the other GCF's defragged fine.

Open Source FTW!
I created rpm packages for openSuSE 11.1 (and 11.0)

here are repos: http://download.opensuse.org/repositories/home:/etamPL/

I separated this in 3 packages: libhl2, libhl2-devel, HLExtract

Hi

I try to use HLLib with MinGW compiler, but I have this error:
C:\...\HLLib.h|740|error: 'HANDLE' does not name a type

Where is normally defined HANDLE ?

EDIT 1: I have added this lines at the begin of HLLib.h, and now HANDLE is ok:
#ifdef _WIN32
# include <windows.h>
#endif


EDIT 2: Now I've several error with linker such as:
undefined reference to `HLLib::CPackage::GetRoot()'

The linker finds HLLib.lib, but the c++ function are unknown (I use directly the c++ class and functions)

EDIT 3: A solution, but it's ugly, it's to include all files from source in my project. It compiles and links correctly :)
============================================

Another problem : in the main.c of HLExtract, it's hl.h that is included (line 20), but it doesn't exist. What is hl.h ?

Thank.

12. NemPosted: Oct 16th, 2009 - 12:35:53 am
You need to include ..\lib\HLLib.h not <hl.h> in Main.c; the latter is for the Linux environment. The top should probably read:

Code:
#ifdef _WIN32
# include "..\lib\HLLib.h"
# ifdef _MSC_VER
# pragma comment(lib, "../../../lib/HLLib.lib")
# endif
#else
# include <hl.h>
#endif

Including Windows.h before HLLib.h should work fine without modifying any HLLib files.

If you aren't using Visual Studio, you should build your own .lib and .dll.

Just noticed that the link HLLib v2.2.0 Archive (338 KB) links to the non-existent file http://nemesis.thewavelength.net/files/files/hllib212.zip rather than http://nemesis.thewavelength.net/files/files/hllib220.zip which is what it should be.

14. NemPosted: Dec 28th, 2009 - 11:37:12 am
Thanks, fixed. free

15. MadJawaPosted: Dec 29th, 2009 - 3:12:02 pm
Hey, I just downloaded the sources and tried to compile them on Linux, and I got errors about functions like "strlen", etc. I had to include <string.h> in 2 or 3 files in HLLib to be able to compile it.
