run-time error "boost_log-vc100-mt-1_49.dll" - c++

this may sound like a silly question, but it would be really useful if there was a way around this.
I am writing a c++ code using microsoft visual which uses eigen, matlab, and ilog cplex libraries. It can be build without problem but there is a run time error as follow:
[Translated]
impossible to start the program because it lacks "boost_log-vc100-mt-1_49.dll".
Try reinstalling the programe for courriger this problem.
6 months ago I tried to use boost library but I gave up. After I deleted all dependencies to boost and I used Eigen without any problem. Even I can not run previous versions of my code now! Maybe I deleted a file some where?
Moreover, I tried my code on another machine and the error is the same. So, it looks it's not a system error.
I appreciate any advice you may have.
Thank you.

It's solved!
Matlab has some boost libraries and the link between MSV and matlab was not working though it was mentioned in linker. I copied those dll files to the current folder and now it is working.

How to get wxWidgets working in Visual Studio 2012

I've got a problem for which I would very much like a solution please:
All I'm trying to do is use wxWidgets in Visual Studio 2012 (in C++), and make it accessible to my code project. That shouldn't be so hard, should it? But as usual, even though there are programming tutorials for it, wxWidgets is evidently one of those things that has no proper documentation just to simply get it running, or if it does then I sure can't find it.
I downloaded the installer for Windows and installed it. When it finished, it gave me a message that said:
wxWidgets was installed successfully!
Please note: before using wxWidgets in your application,
you must build the library using the same compiler you
use for building your program.
Please see docs/msw/install.md file in the installation
directory for the detailed instructions about how to build
wxWidgets and use it from your application.
It should be noted that I think I remember something on the website or somewhere saying that I can just include a header file into my project and forego the DLL altogether (which is what I'd prefer to do, if possible), though I may possibly be misremembering that or confusing it with something else.
Anyway, when I opened the docs/msw/install.md file, I found (amongst other things) these instructions:
--- From the IDE
Ready to use project files are provided for VC++ versions 8, 9,
10, 11, 12, 14, 15, 16 and 17 (also known as MSVS 2005, 2008, 2010, 2012,
2013, 2015, 2017, 2019 and 2022 respectively).
Simply open wx_vcN.sln (for N=8, 9, 10, 11, 12, 14, 15, 16 or 17) file,
select the appropriate configuration (Debug or Release, static or DLL)
and build the solution. Notice that when building a DLL configuration,
you may need to perform the build several times because the projects
are not always built in the correct order, and this may result in link
errors. Simply do the build again, up to 3 times, to fix this.
Of course, it doesn't even say WHERE the "wx_vcN.sln" files are, but I ran a file search and found them in C:\wxWidgets-3.1.6\build\msw and I opened the one called wx_vc11.sln, because that seems to be the one that corresponds to VS2012, right?
Anyway, it took a LONG time to load, because it had to keep scanning through thousands of files and so forth, but when it was finally finished, I did the "Rebuild All" command thrice in a row, like it says to do (which also took a while).
But I'm not sure where it even put the actual DLL file. It says that it's in C:\wxWidgets-3.1.6\build\msw....\lib\vc_lib\wxmsw31ud_xrc.lib, but where the hell is "...."? It doesn't even bother to specify the entire path! What kind of nonsense is that?! I just want the file so that I can put it into my project! Or better yet, just a .h file that takes care of everything would be great. Supposedly there's one to include called "wx/wx.h", which then includes everything else, I think, but I don't know if that one indirectly also requires a DLL.
I always have problems with DLLs, anyway, though I'll use one if I absolutely have to. You'd think it would be the easiest thing to import a DLL into a project, but for some reason, I've never been able to find any sort of tutorial that explains a specific, step-by-step way to do it which is guaranteed to work, so on the rare occasion that I actually need to use a DLL (99% of the time I can just rely on my own code and the .h files included with Visual Studio), I always end up muddling through it until it FINALLY works by sheer accident (if I'm lucky). Mostly, it just reports errors for one reason or another, that it's not properly included or compatible, or that the header files that I'm using which reference it keep showing the same errors, as though I hadn't even imported the DLL file at all! I've been programming for about 30 years, and I work on things like AI and compression and cryptographic algorithms. I don't say this to brag, but to point out that if someone as experienced as me has trouble getting a DLL to attach properly to a roject, then there's something severely wrong with the whole process, or the documentation for it! I HATE using DLLS, because it's always a HUGE chore, but I'll do it if there's absolutely no other way (though I'd appreciate step-by-step instructions, if you don't mind).
But enough about that. In any case, I have an example project in which wxWidgets is being used in conjunction with Vulkan, and though it has compilation errors (because Vulkan didn't properly install on my machine (when I try to run the sample programs it says they're missing DLLs - big surprise) and as it turns out, I don't think it's compatible with my video card, anyway (which might possibly be why it didn't install properly), so I think I'll have to resort to OpenGL instead - PLEASE tell me that's compatible with wxWidgets!), but even in that example project, it has errors where it's trying to include and use wxWidgets stuff (like "wx/wx.h"), even though that's supposed to be a complete and already working project! I can't find any DLL files or the header files in question anywhere in the project directories!
So anyway, there's got to be an easier way to get this all set up, just to the point that I can make a simple test program using wxWidgets, and compile it. I'd REALLY like to be able to get at least that much working sometime tomorrow morning, so I'd greatly appreciate any help you can give me! Thank you.
#ThisIsMe,
First of all you need to educate yourself on properly using C++.
When you acquire the C++ code it contains of 2 portion - header file and source code.
Header file is what you call a declaration you declare you classes there - class name, member variable and method.
In the source files You define what you declared and you put an actual code there.
Now with that in mind:
wxWidgets contains both header and source files. When you downloaded the installer and did the installation it just copied the "text file" (headers and sources) into the folder of you choice.
Now as you can imagine text files are not executable - you need to compile them into the binary files And that is exactly what you did. (I don't know why you did it 3 times though - I guess you got an errors after building 1st and 2nd time).
Now, you said you have a project that (either uses wxWidgets or you want to incorporate wxWidgets into - which one is it, BTW?). The answer to this question will help direct you to a proper solution.
Now, you said that you tried the Vulkan and it fails to run the demo. How did it fails? Did it produce an error? What was it? Did it even run?
Now wxWidgets does support OpenGL as can be seen by looking at the documentation and checking the different samples that comes with the library, but I'm just curious if what you are seeing from Vulkan is really an incompatibility with the Video Card.
So, we need you to answer the questions I put and so we can help you further. Just keep in mind - C++ is not for the beginner programmers and if you are struggling with understanding the difference between compilation, installation , headers and sources - it will be very hard for you.
Maybe you should start with something simpler - like wxPython and forget about C++ for now.

How to create a portable executable with allegro 4.4.2

So I am creating a C++ program using the allegro version 4.4.2 library and I need to be able to produce an executable package which I can submit to a course instructor and have run on his computer without issues. I am developing the program using DevC++. If I am understanding this correctly so far, I need to link to a static library for allegro and then the executable should include the library info and thus the library itself is not necessary to have included in the executable package. I have also seen some recommendations regarding third party tools that produce executable packages, but these seem to be more general (not necessarily allegro compatible?) and I am hoping to avoid downloading more third party software.
I have tried linking to the static library liballegro-4.4.2-monolith-static-mt.a but for some reason when I do this I get a whole slew of undefined reference compile time errors. I have read that it is necessary to have #define ALLEGRO_STATICLINK included in the project, I have this statement at the top of my main source file but I am not sure if I am meant to define this somewhere in the project options instead?
Any guidance or link to resources which will help me solve my problem would be extremely appreciated! I am just getting into the meat of programming with C++ beginning to learn object oriented programming methods, I still occasionally struggle with the basics so thank you in advance for your help!
Backstory (if interested/relevant?): I am taking a Game AI programming course for which we need to create some example programs to demonstrate AI algorithms. The course specifies Java but I am most familiar with C++ and the course instructor says this is fine but I must be able to submit an executable to him which he can just run on his computer without issues. To best achieve what the course asks I feel the allegro library (which I already have installed) will be of great help, mostly for drawing graphics to the screen and such.
So I just ended up using a dynamically linked version of my program and including the appropriate .dll files which turned out to be a lot less work than I thought it would be.
Basically I just had to ensure the allegro-4.4.2-md.dll from the bin folder was included in the folder with the executable. I then sent off the package (the .exe compiled file and the needed supporting files such as bitmaps sound files etc) to a few friends and had them try to run it. They then gave me the warnings from their computers along the lines of "Test.exe cannot be run ****.dll cannot be found".
I searched the exact names of the dll files they were receiving warnings for in the folder with my game and voila it now seems to execute on whatever PC it is sent to.

OpenAL32.dll missing error

I have downloaded gorilla-audio source code to use it in my software, but when I use the external library from OpenAL (in gorilla-audio, the OpenAL32.lib) the project compiles with no errors or anything, but it doesn't run normally, I still haven't implemented anything from gorilla sound, just wanted to check that after adding the library it would still work the same before editing anything, but it just doesn't, I have linked everything and used the correct version of .lib but when I run the project it says:
The program can't start because OpenAL32.dll is missing from your
computer. Try reinstalling the program to fix this problem.
What should I do, I've googled that but I'm just scared to download random things, plus I don't even know where should I put it.
Any help guys,
Thanks ^_^

PointCloudLibrary project -> pcl/io/boost.h is causing problems: AccessViolationException

my program is in C#, but this project is in C++.
I need to include pcl/io/boost.h in order to work with pointclouds.
My problem however is that I get an AccessViolationException error when initializing the class which includes it. It gives this explanation:
Attempted to read or write protected memory. This is often an
indication that other memory is corrupt.
it took me 2 days to figure out that the problem is with boost, but I had trouble with it before...
I run windows 7, VS 2010 x64 installed everything of pcl in x64.
Ok I fixed it, turns out I could work around the error by looking at what I use from boost, (shared_array) and check if there is a library in the boost folder, instead of pcl/io/boost.
So for future references, if you get an error on a pcl library from a third party, check if u can use the third party library instead of the pcl/third party.

Compiling Allegro 4.2 For MinGW/CodeBlocks

I'm having trouble getting Allegro to Compile. When I begin the fix.bat mingw, it gives me an output which says:
Configuring for Windows/Allegro...Stop!
Yet, when I try to compile the rest by typing mingw32-make.exe, the following is output:
makefile.all:248: ***recipe commences before first target. Stop.
I've been spending a good hour trying to get this to compile, and there I haven't been able to find much on the net in terms of troubleshooting specifically for MinGW.
Everything I've done has been from here, though nothing past the point of compilation.
If anyone would like a log file of some sort, please let me know how I can provide that and I will as soon as possible.
First, there's no reason to use Allegro 4.2 as it is past end of life. If you want to use the 4 series, you should be using the 4.4 branch.
http://www.allegro.cc/files/?v=4.4
It's possible that the Makefile on it will just work, but you may also need to update your copy of MinGW in case the version you have is buggy.
Also, there's not much use in compiling Allegro yourself unless you are planning on working on the library itself. The link above has binary downloads that include everything you need to use the library.
