OpenCV : CMake Error at /opencv-2.4.9/cmake/cl2.cpp - opencv

CMake Build error:
I configured CMake and run make command to build Opencv. It gets stopped when It reached to 82%.
error is :
CMake Error at /opencv-2.4.9/cmake/cl2.cpp : 50 (string):
string does not recognize sub-command MD5


I myself fix the issue by commenting the line caused the error.


Try to upgrade CMake.
You can also try to comment the line out and try again!

Can't build todo_ddc project

I want to try polymerize so I have found and use that post. But I met issues when try command
pub run polymerize:polymerize build
It works some time and then return bazel's error:
2017.35.08 16:35:06.015 polymerize [INFO]: Running bazel ...
____Loading package:
ERROR: while parsing ':all': error loading package '': Encountered error while reading extension file 'BUILD.test_app.bzl': no such package '#build_files//': No WORKSPACE file found in /private/var/tmp/_bazel_kelegorm/df7a1dbca8a607bc3485e726bb483b2b/external/build_files.
How can I solve that problem? Why it happens? Why I can't find any mention about that error? What have I missed?
Thanks!

There was a problem with newest bazel versions. Just upgrade to latest polymerize (v. 0.8.6+1) and it should work again.
To start from a clean workspace just do a :
git clone git#github.com:polymer-dart/todo_ddc.git
cd todo_ddc
pub get
pub run polymerize:polymerize build

Compilation project with Cmake . I'm getting an error

I'm trying to compile a project with CMake. I'm getting an error:
Found OpenCV Windows Pack but it has not binaries compatible with your
configuration.
You should manually point CMake variable OpenCV_DIR to your build of OpenCV
library.
Call Stack (most recent call first):
CMakeLists.txt:9 (FIND_PACKAGE)
CMake Error at CMakeLists.txt:9 (FIND_PACKAGE):
Found package configuration file:
C:/Users/Ghenja/AppData/Local/opencv/build/OpenCVConfig.cmake
but it set OpenCV_FOUND to FALSE so package "OpenCV" is considered to be
NOT FOUND.
I don't understand what is happening. Please help me to solve this problem.

Clean your project and remove CMakeCache.txt. OpenCV_FOUND is probably cached now.
If that doesn't work, then run your cmake command with additional flags just to be sure:
cmake -DOpenCV_FOUND:BOOL=ON -DOpenCV_DIR=/path/to/your/OpenCV

ChicagoBoss failed to run on version OTP18.1

I am currently using newest erlang version otp/18.1 to run ChicagoBoss, but I see this error
ERROR: compile failed while processing /home/datumwiine/ChicagoBoss-0.8.15/deps/riak_pb: rebar_abort
What could be wrong?

Try typing in the command line the following commands:
git clone https://github.com/ChicagoBoss/ChicagoBoss.git
cd ChicagoBoss/
make

Error while building opencv_contrib opencv 3.0

I wanted to use the "extra" modules, that come as opencv_contrib from here for other functions of opencv 3.0. I followed the instructions as per the page, for building and compiling the modules, but am stuck with this error
Command:
cmake -DOPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules ..
Error:
<Skipping the common Cmake statements and going straight to the error>
CMake Error at opencv_contrib/modules/adas/tools/fcw_train/CMakeLists.txt:16 (ocv_include_modules_recurse):
Unknown CMake command "ocv_include_modules_recurse".
-- Configuring incomplete, errors occurred!
I checked the CMakeLists.txt as mentioned in the path and there were other lines of code that had ocv_xxx , thus it was not a rename issue (I thought they misspelt opencv).
This is my folder structure:
Opencv
- build
- opencv_contrib
This is to verify if my CMake command was correct, as I had posted above.
Can you please tell me how to rectify this error?
UPDATE 1
As per a suggestion, I tried,by putting the opencv_contrib folder outside the opencv folder structure. The new structure was like this
-Opencv
- build
-opencv_contrib
and my new command was
cmake -DOPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules ..
the error is still the same.

Fixed it, thanks to this question. From that question, I understood that the value of the argument should be correct, to turn on the build or something like that. So I changed my command from
cmake -DOPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules ..
to
cmake -DOPENCV_EXTRA_MODULES_PATH=opencv_contrib/modules .
Plain and simple, without hierarchy information and it worked. Cheers.
