I am trying to load CMU sphinx in visual studio 2013 but getting some error.
The steps which i followed was
I downloaded sphinxbase-5prealpha and pocketsphinx-5prealpha and extracted to same folder.
Then i complied all the projects from both pocketsphinx and sphinxbase in visual studio(it asked me to upgrade the compliers so i did the upgrade)
now after cleaning the project, when i am trying to build all the project it is throwing a error that 'cannot open sphinxbase.lib' which it is showing in pocketsphinx project.
when i checked the 'sphinxbase.lib' file was already there in the linker of the project.
According to this document the 'sphinxbase.dll' file should be added to the bin files, but it is already added in the directory bot release and debug.
Similarly it is present in debug directory also.
Please help me, can anybody tell me what wrong i am doing here??
I am just a beginner only in this area.
Thanks !
You extracted files incorrectly. The layout must be the following:
root folder
\____pocketsphinx
\____ all files like README, src
\____sphinxbase
\____ all files like README, src
You need to download sources and unpack them into two folders - pocketsphinx and sphinxbase. Then open sphinxbase solution and compile everything. Then open pocketsphinx solution and compile everything. Please note that if you downloaded pocketsphinx-5prealpha you need to rename it to just pocketsphinx. Same for sphinxbase.
Please also note that pocketsphinx_5prealpha_win32 is a binary distribution, you can not compile it. Instead, you can include it directly into your projects.

I'm trying to build libpng in MS Visual studio 2015 community edition but when i built it, i got this error (i used cmake to compile libpng along with compiled zlib to produce libpng's soln file ALL_BUILD.vcxproj )
Cannot open include file: 'pnglibconf.h':No such file or directory
I think this a system specific error,when i try to build this on other system it works fine(because pnglibconfig.h was present with MS VS soln folder). Is there any prerequisites that is missing? Update: I tried building libpng in both debug & release mode, both are showing the same error. Zlib builds fine.
Try to add the folder where the png lib headers are to your include list in the VS project settings
If you aren't using "configure", you may need to copy pnglibconf.h.prebuilt from the scripts directory to pnglibconf.h in your working directory. See Section III of the INSTALL file in your libpng source directory.
I have installed open cv and have configured all the path variables as mentioned in step by step procedure.
I tried a sample program to verify whether my installations are correct. I have mentioned all the path for include files, library files and additional path variables in visual studio 2013.
I am getting error "Cannot open opencv2/core.hpp no such file or directory"
When i check the location of the include file under opencv2 folder there is no such file. But i can see the same in github. If i branch out and download the same from github again in my local I cannot see the core.hpp.
Got answer for this issue... This is because from version 3 openCV needs only couple of lib files to be associated with additional library dependency.. Earlier we need to have multiple lib files for the same...
I am trying to install OpenCV 3.0 Aplha. I'm following these instructions
http://docs.opencv.org/trunk/doc/tutorials/introduction/windows_install/windows_install.html
After I download and extract the package, I am supposed to have all the pre-built libraries in the folder :opencv\build\x86\vc12\lib but I don't see them in this folder. This folder only has opencv_ts300.lib and opencv_world300.lib. All the other libraries seems to be missing. Also the bin folder doesn't have the dlls. But statlib folder does seems to have all the static libraries.
I also tried to build the libraries from source, and as per the instructions after building the OpeCVALL.sln in visual studio, I am supposed to have the libraries in the x86\vc12 but the libraries doesn't seem to be building in this folder. After digging through the folders I see that the opencv libraries are found in bin/debug and bin/release folders. I thought I would use these for linking in visual studio but I am not finding the header files in build/include folder
I don't see any of these issues with Opencv 2.49. Any help in debugging this issue with 3.0 would be highly appreciated.
Summary: After I build from source/ or pre-built package, I am able to run the sample applications. But I am not finding the headers and libraries to create a visual studio project from scratch.
Okay I figured out what is going wrong here...
Build INSTALL project manually from the OpenCV.sln by right clicking - > build. This will create the libraries in build/install/x86/vc12 folder. This is where lib,bin and staticlib folders are now residing. Also the include files are in build/install/include.
Library files : located in your cmake folder's lib/debug(or release) folder
DLL files : located in cmake folder's bin/debug(or release) folder
Header files : located in opencv3's build/include folder
i've just downloaded cumulus, POCO, OpenSSL and LuaJIT and visual studio. now i'm trying to compile it as it said in instruction here
however i've never used visual studio and i've never programed on visual c. so i'm stuck at the very begining.
in instruction i've put link above said "Visual Studio 2008/2010 solution and project files are included. It searchs external librairies in External/lib folder and external includes in External/include folder in the root Cumulus folder. So you must put POCO, OpenSSL and LuaJIT headers and libraries in these folders.". i tryed everything but compiler can't find 'Poco/foundation.h'.
and it seems to me if i deal with this error there will more over.
so if someone has expirience in compiling cumulus-server please help me to deal with it.
thanks a lot for you help!
step 1 - create 2 files
cumulus_root_folder/external/lib
cumulus_root_folder/external/include
step 2 - put the headers into the include folder from the other 3 dependent projects
dependent projects are: openssl, poco, luajit.
put openssl file into the external/include from openssl-version/include
put Poco file into the external/include from poco-version/Foundation/include
put SAX, DOM, XML files into the external/include/Poco from poco-version/XML/include/Poco
put Net file into the external/include/Poco from poco-version/Net/include/Poco
put Util file into the external/include/Poco from poco-version/Util/include/Poco
put LuaJIT's headers with the same way.
now you can build cumuluslib.
step 3 - Open your cumuluslib project with specific visual studio version then build it.
When it's done you can see the lib file at cumulus_root_folder/cumuluslib/lib
step 4 - now you have to build the 3 dependent projects and put their lib files to cumulus_root_folder/external/lib its tough mission, maybe you will need 32-bit windows. Do not forget: when you building poco, do it with debug if not, some of your files will be missing.
When you done with building and gathering lib files you can build cumulusserver. Same way as cumuluslib. Then your cumulus.exe will be in cumulus_root_folder/cumulusserver/debug
I opened up the solution file in the [InstallDir]\_make\opencv.vs2005 and modified one of the .cpp files in the highgui library.
While compiling, Visual Studio throws the error -
Unable to start progam
C:/Users/../AppData/Local/Temp/opencv.build/cv_Debug.Win32/cv.dll
The system cannot find the file specified.
I think I am missing something in it. What is the stepped procedure to change and recompile OpenCV library using Visual Studio.
I would appreciate any help!
Thank You..
Unless you downloaded the visual-studio specific version of the open cv distribution files, you need to follow the instructions on the OpenCV wiki, that is
download cmake
have cmake generate makefiles/solutions
build using the generated files
I guess you want to customize a function. You can do this, without recompiling OpenCV from scratch. You can simply copy the .cpp source file locally in your current working directory, and add it(click n drag or add existing file) in the "Source Files" in your project. You might need to copy some other headers as well. You will find everything in the opencv archive. (opencv/modules/highgui/src)
