I get these errors when I try to configure in cmake:
Could NOT find Libwww (missing: LIBWWW_LIBRARIES LIBWWW_INCLUDE_DIR)
but I couldn't find any answer in google, I tried to download "w3-libwww" but I don't know how to include it on project.
I'm following this tutorial:
https://ryzomcore.atlassian.net/wiki/display/RC/Build+Source+on+Windows
I downloaded and installed all SDK and pre-requisites and I try to generate for Visual Studio C++ 10 (2010)
Please use either develop or compatibility-develop branch, the default branch has not been updated for a while and we removed dependency on libwww since :)

I'm building a C++ app which uses the libgit2 library to interact with a git repo. I've installed libgit2 through vcpkg, which also installed the pcre library which libgit2 needs. So far, so good. When I build my project there is no issue, only when I launch the app it throws an error that pcre.dll is not present. This is correct, pcre.dll isn't in my output folder as none of my code has any interaction with it. Libgit2 needs it.
How can I get the dependency of the dependency to be included in my final build?
Pcre is present and accounted for, but none of my code uses it so it doesn't get included in the build of my app. The git2.dll does get included with the build. The paths that need to be added to Visual Studio are there, managed by vcpkg. Everything is setup so that pcre could be included in a build if need be.
I use libgit2 v 1.1.0, Visual Studio 2019 and the latest stable version of vcpkg.
I'm running into the same issue and have opened a PR: https://github.com/microsoft/vcpkg/pull/18289
Based on Neumann-A's feedback in the PR, it looks like there may be a bug preventing the pcre DLL from getting copied to the release/deployment files. For now, you're welcome to use my vcpkg fork which exposes the "builtin" REGEX_BACKEND CMake option, which works around this problem. https://github.com/motevets/vcpkg/tree/fix-libgit2

I've also tried working with Linux WSL (But problems with CUDA installation overthere, their team is working on it), Linux VirtualBox (Not enough resources), and Ubuntu 17.10 I have installed (But Cuda requires Ubuntu 16.04 / 18.04)
What am I missing here? I'm trying any suggestion, stuck on it for a few days. Thanks!
Edit:
I reinstalled Ubuntu 16.04 and the problem was solved. Still don't know how to solve it in windows, but i'll continue use Ubuntu 16.04.
I had this problem earlier while trying to build the Windows version of Marian NMT (the same component that you're having trouble with). I can't remember the exact steps to solve the problem, but the root cause is that the Marian NMT build for Windows does not work with newer versions of Boost, since the source code uses some deprecated calling conventions for timer and chrono libraries (maybe some others as well).
The error message kind of confirms this: it can't find Boost, but on the other hand it says it finds your version 1.67.0. The solution is to use an older version of boost, I've confirmed that it works with 1.60.0.
If you just require a Marian NMT decoder that works in Windows, a project I work on has released a plugin for the Trados Studio translation tool, which contains a compiled marian-decoder executable for Windows: https://object.pouta.csc.fi/fiskmo/TradosStudio/FiskmoTranslationProvider.sdlplugin. You can access the executable by unzipping the sdlplugin file, the StartMtPipe.bat shows how to use the decoder.
I am trying to use socket.io c++ client implementation.I have never used an external library before with c++ so im confused.
This is the library i am trying to use:
https://github.com/socketio/socket.io-client-cpp
So i followed this instructions:
https://github.com/socketio/socket.io-client-cpp/blob/master/INSTALL.md
Installed boost and cmake as its stated and i guess it is fine.
My problem is with the 4th step and the rest of it.
If i run
make install
console throws:
make: *** No rule to make target 'install'. Stop.
current dir looks like:
To be honest i didnt understand what is 5th step, and the installation process in general.How should i include this library in my main.cpp so that i can use it ? What are those visual studio project files generated ?
Edit:
If i open INSTALL visual studio project file and build INSTALL project from solution explorer,i get this error:
Edit2:
After updating websocketpp library now i get this error after build:
if you are having lots of issues this is how i solved mine:
boost 1.7.0 was not working for me.I installed boost 1.65.0
after that update websocketpp library
go to C:\socket.io-client-cpp\.git\modules\lib\websocketpp directory with command line and type
git pull origin master
so after changing boost version to 1.65.0 and updating websocketpp finally it built succesfully.
I'm currently struggling to build OpenCV for the UWP.
I already googled quite a lot and found Microsoft's OpenCV Github Repo which tecnically should do the magic. However, this repo and pretty much everything else I found in this regard are outdated (Visual Studio 2015, old OpenCV versions etc.). I need to use OpenCV 3.3 because it's a cross platform project and I don't want to recompile everything else solely because of an outdated git repo.
Can anyone explain the process of building OpenCV using CMake from the official repo for the UWP?
My first attempt was to simply use the Windows Dlls, however my application than shouts "Failed to load module" at me. Then, I tried to build OpenCV the Visual Studio Project files as stated here and here. However, this doesn't do it for me as it throws the following error:
CMake Error at cmake/OpenCVUtils.cmake:440 (if):
if given arguments:
"(" "OR" "OFF" ")"
Unknown arguments specified
Call Stack (most recent call first):
CMakeLists.txt:317 (OCV_OPTION)
It also tells me to check the CMakeOutput.log but there it's 0 errors everywhere.
If someone could tell me either how to get rid of this error or what to change in the CMake GUI to build OpenCV for UWP, that'd be great!
Edit:
I also tried to compile OpenCV with a platform specific toolchain for WinRT as found in platforms/winrt. It doesn't really change anything though (I'm not even sure if it should), I still get "Unable to load Dll: The specified module could not be found". Maybe GPPK is right in his assumption that it's more an UWP problem than an OpenCV one. Anyways, if anyone knows anything about this, I'd really love to get some help!
Ok, I didn't get an answer yet, so I managed to do it myself (more or less).
Here's how I did it:
Prerequisites
Visual Studio (2017)
UWP SDK
CMake
OpenCV from official repo
Steps
Create a build folder which you want the UWP libraries to built in.
Start PowerShell in this folder and execute the following command (exchange C:\OpenCV with your local OpenCV path): cmake -G "Visual Studio 15 2017" -DCMAKE_SYSTEM_NAME=WindowsStore -DCMAKE_SYSTEM_VERS
ION="10.0" -DCMAKE_VS_EFFECTIVE_PLATFORMS=x86 -DBUILD_TESTS=OFF -DBUILD_PERF_TESTS=OFF C:\OpenCV
If you get the same error message as I did (see question for more details), go to the root CMakeLists.txt in the OpenCV folder and add a # in front of line 317 (OCV_OPTION(ENABLE_PYLINT)). This should fix it, to check, execute the command from above once more.
Ensure that the output claims "Windows RT support YES" and "Building for Microsoft platform: Windows".
Open OpenCV.sln in the build folder. Ensure that all projects are either of type "Windows Store" or "Universal Windows" and build the ALL_BUILD Project twice: Once in Release configuration, and once in Debug. Then build the INSTALL Project.
That's it, you should find the built Dlls in the install folder. Step 3 is probably a bug in OpenCV and will hopefully be fixed in upcoming versions.
I am fairly new to C++ in general (though I am getting used to the basics), but now I am trying to add OpenCV to my projects to access some of the basic image processing features. I have read the documentation so I have a pretty good idea where to start, but I am really stuck with the installation.
I am working with Code::Blocks 16.01, and I have downloaded both CMake 3.4.3 and OpenCV 3.0.0 and 3.1.0. OpenCV has been extracted to "c:\opencv", and I have attempted to finish the build with CMake (using the directions from the OpenCV documentation as well as from several older posts from this site). I am selecting "Codeblocks - MinGW Makefiles" from the list of generators, though I have selected from all of the "Codeblocks" options at one point or another.
Anyway, whenever I try to configure or generate I receive the following error: "The program can't start because libintl-8.dll is missing from your computer." So yeah, I am stuck.
It is worth noting that many, if not all, of the posts I have found refer to a directory named "\x86\mingw\lib", however I cannot find "mingw" in any of the OpenCV downloads (and the most recent is missing "x86" as well) - so none of these posts have been particularly useful to me (for example):
How to compile a program using OpenCV 2.4.3 with Code::Blocks?
Put the path to all the MinGW dll files in your pc's path variable. Check your Code::Blocks installation directory ( C:\Program Files (x86)\CodeBlocks\MinGW\bin ) if it does not exist, you'd have to download and install MinGW separately. You'd have to add the MinGW .dll files to the path environment.
