Hello,
I'm trying to build OpenCV on Ubuntu 16.10. The build process is interrupted with the error shown below.
Obviously the file "/usr/include/c++/6/stdlib.h" exists in my system. I have tried this with: OpenCV master branch, OpenCV 3.1.0, 3.0.0, 2.4.13.
Could you please give me some clues what can cause this error and how to solve it? All ideas are welcome :)

Build failure with android ndk r13b and c++_shared
Because of other dependencies we need to build openCV with ndk r13b and the stl c++_shared. We build on mac OSX.
First we had to fix a small thing in *android.toolchain.cmake* since apparently some header path did change in the ndk 13.
We changed this:
> set( ANDROID_STL_INCLUDE_DIRS "${ANDROID_NDK}/sources/android/support/include" "${ANDROID_NDK}/sources/cxx-stl/llvm-libc++/libcxx/include" "${ANDROID_NDK}/sources/cxx-stl/llvm-libc++abi/libcxxabi/include" )
to:
> set( ANDROID_STL_INCLUDE_DIRS "${ANDROID_NDK}/sources/android/support/include" "${ANDROID_NDK}/sources/cxx-stl/llvm-libc++/include" "${ANDROID_NDK}/sources/cxx-stl/llvm-libc++abi/include" )
Removed *libcxxabi* und *libcxx* from path.
We configure the build:
> cmake_android_arm.sh -DANDROID_STL=c++_shared -DBUILD_SHARED_LIBS=YES -DCMAKE_BUILD_TYPE=RELEASE -DBUILD_ZLIB=ON -DANDROID_NATIVE_API_LEVEL=9
We also tried using a newer android version (21) but it results in the similar behaviour. Performing make results in the following error:
> ~/software/Android-NDK/ndk/sources/cxx-stl/llvm-libc++/include/cwctype:68:9: error: '::iswblank' has not been declared
using ::iswblank;
Building with android version 21 results in a similar error somewhat later in the build:
> ~/software/Android-NDK/ndk/sources/cxx-stl/llvm-libc++/include/cmath:313:9: error: '::signbit' has not been declared
using ::signbit;
When searching for the error we found some information that changing the math.h imports to cmath should fix the error. We tried this but had no success in finding a way to make the build work.
What can we do to get the build to work? If more information is needed I am happy to provide it.
EDIT 1: Spelling
EDIT 2: Again similar behaviour with the ndk r14-beta1. We receive the following error for the new beta sdk:
> ~/software/Android-NDK/ndk/sources/cxx-stl/llvm-libc++/include/cwctype:68:9: error: '::iswblank' has not been declared

Undefined freetype symbols when building openCV 3.2.0
openCV: 3.2.0
OS: Yosemite 10.10.5
compiler: Apple LLVM version 7.0.2 (clang-700.1.81)
I built openCV 3.2.0 successfully, but then I found out that I needed `ffmpeg` support. I installed `ffmpeg` with homebrew, and when I tried to build openCV again, the build failed because of undefined symbols in `freetype` libraries. I then tried to build openCV again without `ffmpeg`, and the build failed with the same errors. Before I installed `ffmpeg` I ran `brew upgrade` and I saw that it upgraded `freetype`, so this may be the source of the problem, but if so I don't know what to do about it. Here's the command I'm running
PYTHON3_DIR=`python3-config --prefix` # Get python 3 path
VIRTUAL_ENV=`python3-config --prefix`
cmake -D CMAKE_BUILD_TYPE=RELEASE \
-D CMAKE_INSTALL_PREFIX=$VIRTUAL_ENV \

-D INSTALL_PYTHON_EXAMPLES=ON \
-D BUILD_EXAMPLES=ON \
-D BUILD_opencv_python3=ON \
-D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib/modules ..
This produces no errors, but when I run `make` I get
[ 26%] Building CXX object modules/freetype/CMakeFiles/opencv_freetype.dir/src/freetype.cpp.o

and a bunch of other missing symbols. When I run `nm freetype.cpp.o` those symbols are listed as undefined all right, but I can successfully install openCV 3.2.0 (with `ffmpeg` support) on Ubuntu 16.04 using `gcc 5.4`, and those same symbols are undefined in `freetype.cpp.o`, so I guess it's trying to link them from another file, but I have no clue which.
I really need installed it on the Mac. I only installed in on Ubuntu as a temporary stopgap. Can you give me any advice?

opencv 3.2 build nvcc device fatal error C1083
I'm trying to build OpenCV 3.2 with CUDA and TBB enabled. I've followed the usual directions and generated my solution with CMake. When I try to build opencv_world in Visual Studio 2013 I get the NVCC error on cuda_compile_generated_median_filter.cu.obj:
fatal error C1083: Cannot open include file: 'tbb/tbb.h': No such file or directory
The include path is correct for the TBB package. I can Ctrl-Shift-G on the include tbb and it navigates to the tbb.h file. I've restarted the machine. But the compile still fails.

Build Opencv 3.2 fails on Windows 8.1 with VS2013
Building Opencv-3.2.0 failed on my Windows 8.1 VM, using cmake 3.5.2 and visual studio 2013:
First, Visual Studio fails without showing any helpful message, but after digging I found out `cmake/cl2cpp.cmake` crashes every time. I fixed it by changing this line:
string(REGEX REPLACE "/\\*([^*]/|\\*[^/]|[^*/])*\\*/" "" lines "${lines}") # multiline comments
to:
string(REGEX REPLACE "/\\*[^\n]*\n" "" lines "${lines}") # multiline comments
string(REGEX REPLACE "[^\n]+\\*/\n" "" lines "${lines}") # multiline comments
But ok, that could be a CMake bug.
After that, I'm getting the following errors:
```

7> type is 'unknown-type'
```
The code it is referring to in `parallel.cpp`:
#if defined WIN32 || defined _WIN32
SYSTEM_INFO sysinfo;
And at the top of that file,
#if defined WIN32 || defined WINCE
#include
This error is fixed by checking for _WIN32 as well:
#if defined WIN32 || defined _WIN32 || defined WINCE
#include
I finally got the whole build to succeed after adding `|| defined _WIN32` to a bunch of cpp files.
My question basically is: **am I doing something wrong or is this a bug that should be reported?**

build OpenCV 3.1 for android with openCL support
Hi All!
I tried OpenCL on my OpenCV project and the result is a huge improvement in terms of performance so I would like to try OpenCL on android.
I use this [article](http://docs.opencv.org/3.1.0/d7/dbd/tutorial_android_ocl_intro.html) to guide me.
Here is my cmake command:
cmake -GNinja -DCMAKE_MAKE_PROGRAM="/usr/bin/ninja" -DCMAKE_TOOLCHAIN_FILE="../opencv-3.1.0/platforms/android/android.toolchain.cmake" -DCMAKE_BUILD_WITH_INSTALL_RPATH=ON -DWITH_OPENCL=YES -DANDROID_ABI="armeabi-v7a" ../opencv-3.1.0
and I use this command
ninja install/strip
I have no errors neither on compilation nor installation. And an `install` folder has been created. I think all is perfectly fine except that I can't find the `libopencv_java3.so` file !!!!! so:
1. Do you know how I can generate libopencv_java3.so ?
2. Do you know how I can target several abis ? I tried `-DANDROID_ABI="armeabi-v7a" -DANDROID_ABI="x86"` and `-DANDROID_ABI="armeabi-v7a x86"` but it is not correct.
Thank you !

How to compile opencv with local libpng version?
I'm on a ubuntu-like Linux machine without root access. I have a local version of libpng-1.6.26 that I installed in my home account (the default libpng is libpng12). I successfully built opencv-2.4.13 with a cmake command that explicitly referenced my local libpng:
cmake -DPNG_INCLUDE_DIR=/home/tmpguest/INSTALL/libpng/install -DPNG_LIBRARY_RELEASE=/home/tmpguest/INSTALL/libpng/lib/libpng16.so ../
I built my other software, but then the problem occurs. When I try to run my software, I get this complaint:
libpng warning: Application built with libpng-1.5.14 but running with 1.6.26
This is confusing to me. I run 'ldd' on some of the opencv libraries and I see both libpng-1.6.26 and libpng12:
libpng16.so.16 => /home/tmpguest/INSTALL/libpng/lib/libpng16.so.16 (0x00007fffe9944000)
libpng12.so.0 => /usr/lib64/libpng12.so.0 (0x00007fffe45ff000)
So, where does the libpng-1.5.14 warning come from? I think the libpng12 comes from other libraries that opencv is linked with (libcairo), but I don't know where the libpng-1.5.14 warning comes from. However, source code for libpng version 1.5.12 is included in my opencv tarball (from github) in the opencv-2.4.13/3rdparty directory, but I did not build it explicitly. Is that where the libpng-1.5.14 warning comes from?
How can I fix this problem? I think I need to build opencv libraries that only link in one libpng library to get rid of the multiple libpng warning.

Issue with build on symbols OpenCV 3.2.0 / VS2015 / Release (x64)
Hey all
I've been hitting a problem for a couple of days now of getting OpenCV to run within a project with VS2015 but am having library linking problems.
Specifically, I'm the maintainer of the ofxCvMin addon for openFrameworks, and am currently trying to upgrade the libraries from 2.4.x to 3.2.0. (I've built and linked opencv libs a few times for windows and osx over the years).
I can successfully build Debug and Release libs (this wasn't an issue at all).
(note : current setup is static libs, not using static CRT)
I managed to build an application linking the debug libraries (with a little extra help on #opencv IRC), but Release is still is not working. **VC++ doesn't seem to recognise the imported symbols**.
Diggiging deeper, it seems that the C++ application is looking for :
?deallocate@Mat@cv@@QAEXXZ
public: void __thiscall cv::Mat::deallocate(void)
when building. But in `opencv_core320.lib` we have:
?deallocate@Mat@cv@@QEAAXXZ
public: void __cdecl cv::Mat::deallocate(void) __ptr64
which VC++ doesn't consider to be a compatible symbol. I presume there are some project settings which affect the symbol naming strategy (__thiscall <> __cdecl hints at a C++ vs C style).
Is anybody aware of project settings which affect how the symbols are decorated when using OpenCV with VC++?
Thank you
NB : CMAKE is not an option here as the projects/solutions need to be openFrameworks generated (although could be used to look into which build settings are present)

I build OpenCV 3.2.0 from the sources (including the contrib modules) using the `3.2.0` branch. And when I import it within python, through `import cv2`, I get an `undefined symbol` error. That in my experience seems like a linking error.

My flags in `cmake` are as follows:
cmake \
-D CMAKE_BUILD_TYPE=RELEASE \
-D CMAKE_INSTALL_PREFIX=/usr/local \
-D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules \
-D BUILD_NEW_PYTHON_SUPPORT=ON \
-D WITH_TBB=ON \
-D WITH_QT=ON \
-D WITH_OPENGL=ON \
-D BUILD_TIFF=ON \
-D BUILD_SHARED_LIBS=OFF \
-D BUILD_EXAMPLES=ON \
..
I see in other posts that the problem my be due to the sharing libraries, and so I tried with `-D BUILD_SHARED_LIBS=OFF` but that doesn't work either.
Let me know if you need more information. Any help is appreciated.

opengl_interop.o build error
I recently started to use OpenCV on Qt Creator 4.2.1. Now I am trying to run opengl_interop.cpp from samples/opengl but I am getting this error: **opengl_interop.o: undefined reference to symbol '_ZN2cv3ogl13unmapGLBufferERNS_4UMatE'**.
OS is Ubuntu 16.10.
