I am working on a project that uses v8 engine. I have followed the instructions on v8 git page to compile it and generated some .so files. But now after that there are no more directions as how to proceed with those library files. I wanted to try out with the hello-world example provided but it uses static libraries(but we need dynamic ones). I couldn't find any relavant documentation nor tutorials on internet...
Could anyone point me to some directions as how to proceed to include those dynamic libraries to my program..
This tutorial helped me a lot:
https://medium.com/dailyjs/how-to-build-v8-on-windows-and-not-go-mad-6347c69aacd4
and also, if you don't want to have this kind of problem with the libraries, you can use the v8 NuGet:
https://github.com/pmed/v8-nuget
You can install directly into your project in VisualStudio and you don't need to make any reference.

I'm trying to add a static library to my C++/ROS project and having trouble wondering where to start. I have the project currently working with a CMake file to build it and have downloaded (and can build) an external static library that I want to use in the project.
I am very new to CMake and C++ in general and am working on a project that I haven't created myself. I've read a lot of tutorials on how to add libraries but I'm stuck at knowing where to start as I know there are many different steps needed. I was looking at find_library(), add_library() and ExternalProject_Add() but I don't really understand the difference and the documentation doesn't make it much clearer. As it stands the CMake file has very little in it so I was wondering what exactly I need to add and what commands are best just to be able to use this library in my project. Specifically, I guess what set of commands would I add to a pretty empty CMake file for it to work given I have the lib.a file. Sorry for the vagueness but any help would be appreciated.
I'm trying to use the xgboost library to basically translate a model I developed in R to C++.
I've not used an external library and other sources online did not help me much so decided to ask the question here to hopefully find the way to do it.
Here's the library I need to use in my C++ code: https://github.com/dmlc/xgboost
I'm using Visual Studio Ultimate 2013. I have a make file that I use to define my project.
I am looking for the proper way to use this library in my C++ code.
If you have ever used this library before, I really appreciate your help. Any hint will be appreciated.
To use the library, one needs to first build it. I could not manage to build the master branch. So, I decided to use the V0.4 instead. I built the solution in that branch using Visual Studio and it produced the dll and lib files. One can then import the .dll file by using Add_library to add it via Cmake. After Add_library, the include directories need to be added by include_directories command.
I need to generate .a and .so files in the end. I'm working in windows and could not find a way to generate these files, yet!
So I found the way to resolve this issue. I shared it in another answer
Add an external library (e.g., Eigen) via CMake
Hope this helps people who are looking!
I'm a newbie when compiling and adding 3rd party C++ libraries into XCode... So here's the problem. I have .cpp files wich depend on 3 libraries. OpenCV-Eigen-SuperLU. So far think that I managed to add correctly OpenCV-Eigen, but I got trouble adding SuperLU.
I'm really confused on where should I include source files paths??. Some tutorials say that I need to create a static lib... other that I need a framework... on the other hand there are XCode project template which just include src files into a folder inside XCode project's and then reference them from build setting properties. Anyway I really need some guidance here.
So here's my setup for most of the libs. I have a folder within the XCode project with all dependencies.
Then... on project build settings I setup header search paths-- and library search paths. To point that folder
Headers for SuperLU are found correctly... but I get Linker errors.
So as you can see, I have no idea what to do... I'm Sorry but as I told on beginning I'm a newbie adding libs into XCode... plus documentation of procedures it's not good at all. So if anybody could help me with some guidance or links where I can start understanding how the linking process works would be great.
I'm a little desperate at this point, os any kind of help would be really really great.
Thanks a lot.
The problem is that both SuperLU and Objective-C define YES and NO. So you get a conflict.
In the end I was advised to create a different target to compile all SuperLU as a pure c++ project with gcc compiler. That made it possible for iOS app to use the lib as a dependency.
I am new to the XCode environment so apologies if this sounds trivial.
I am trying to use a third party library using for OpenCV that helps me do some blob analysis, CCL etc. Hosted here
I have searched a lot but there doesn't seem to be much documentation on how to go about adding and using these new libraries. I am using XCode 4.5.2, OpenCV 2.4.2.
When I simply add all the header files to the project folder and #include them in the source code, it fails to compile. I have also tried adding the "Header Paths" but it doesn't help. What am I missing?
I have tried to follow the instructions (compiling it using the terminal but it doesn't compile too) I am not clear on how or when exactly to use CMAKE.
Any help will be appreciated. Thank you.
I would suggest you using CvBlob on google code which is different from the one on willowgarage, I have got recently confused with this so take a look at this question for alternative blob analysis libraries.
Moreover, CvBlob has also a good support community here. (Search on "[cvblobslib]" or on "[blob] [opencv]")
Try this: cvBlob: OSX installation
Once you get it compiled, you need to include the library under Link Binary with Libraries in Build Phases. (This screenshot shows the core, imgproc, and highgui libraries. Your cvBlob library would go in the same place.)
I'm teaching myself OpenGL and I'm implementing ttf text rendering using FreeType 2. I downloaded the library from
http://gnuwin32.sourceforge.net/packages/freetype.htm
and after a couple of minor issues I got it running properly. The thing that's bothering me is that I have to place a copy of freetype6.dll in the directory with my executable in order for the thing to run. I generally try to avoid a bunch of unnecessary dll files floating around. I'm sort of new to windows programming, but from what I understand most libraries can be built to run fully from a lib rather than requiring a dll at runtime. Looking through the documentation from FT is making my brain melt, so I thought I would ask here to see if there were any devs that have worked with FT before and if so, do they know how to build the library such that no dll is required at runtime.
Thank you in advance for any advice or support.
Check out this link. See the section Optional: Installing FreeType (by compiling it yourself)
Follow the instructions and you'll be good to go.
you can generate static lib by getting source code of it... then you won't need dll...and i think freetype2's source is available...
It is something DLL generic. All your DLLs should be in PATH similarly to LD_LIBRARY_PATH. Also under Windows (unlike Unix) the current directory is always in the PATH. So you just need to set your PATH variable to point to location of this dll.
Now, for Unix... you probably just have this library installed by default like hundreds of other useful libraries that are not present under Windows by default.
So... No unless you link statically you should use DLL somehow. And my suggestion - use dll.
