OpenCV in Cygwin - make: *** [Makefile:128: all] Error 2 - c++

I'm trying to install OpenCV on my Windows, using cygwin, using these commands :
cd ~
git clone https://github.com/opencv/opencv.git
cd opencv
git checkout 2.4.5
mkdir build
cd build
cmake -G "Unix Makefiles" ..
make -j8
sudo make install
The Problem is after i try to use command: "make -j8" , i get this error at around 67% :
[ 67%] Building CXX object modules/legacy/CMakeFiles/opencv_legacy.dir/src/calibfilter.cpp.o

make: *** [Makefile:128: all] Error 2
How do I solve this problem? I already tried using "make" instead of "make -j"
there is no difference
EDIT: I want to use the specific 2.4.5 version of OpenCV

How to cross compile C++ DCMTK projects with CMake (from Ubuntu to Windows)

I'am trying to cross-compile the simplest DCMTK example I found and I can get it built.
I am running Ubuntu 18.04.4 LTS to cross compile using x86_64-w64-mingw32.
I have checked these answers and examples too, but they didn't work for me:
CMake: Cross-compiling linux-to-windows with MinGW does not find some system headers
https://gitlab.kitware.com/cmake/community/-/wikis/doc/cmake/cross_compiling/Mingw
This is the only file of the project (main.cpp):
#include "dcmtk/config/osconfig.h"
#include "dcmtk/dcmdata/dctk.h"
using namespace std;
int main()
{
DcmFileFormat fileformat;
OFCondition status = fileformat.loadFile("sample.dcm");
if (status.good())
{
OFString patientName;
if (fileformat.getDataset()->findAndGetOFString(DCM_PatientName, patientName).good())
{
cout << "Patient's Name: " << patientName << endl;
} else
cerr << "Error: cannot access Patient's Name!" << endl;
OFString patientID;
if (fileformat.getDataset()->findAndGetOFString(DCM_PatientID, patientID).good())
{
cout << "Patient's ID: " << patientID << endl;
} else
cerr << "Fatal Error: cannot access Patient's ID!" << endl;
} else
cerr << "Error: cannot read DICOM file (" << status.text() << ")" << endl;
return 0;
}
This is my CMake.txt configuration file:
cmake_minimum_required(VERSION 2.8)
PROJECT(test1DCMTK)
add_executable(${PROJECT_NAME} "main.cpp")
SET(DCMTK_DIR /usr/local/include/dcmtk)
ADD_DEFINITIONS(-D_REENTRANT)
INCLUDE_DIRECTORIES(${DCMTK_DIR}/include)
LINK_DIRECTORIES(${DCMTK_DIR}/lib)
TARGET_LINK_LIBRARIES(test1DCMTK ofstd dcmdata)
And I am using this toolchain file:
### CMAKE cross compile settings for Windows running from Ubuntu 18.04.4 LTS x86_x64 amd64 ###
# the name of the target operating system
SET(CMAKE_SYSTEM_NAME Windows)
SET(TOOLCHAIN_PREFIX x86_64-w64-mingw32)

# adjust the default behaviour of the FIND_XXX() commands:

# programs in the host environment
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
When I configure, with CMake, I get this:
The C compiler identification is GNU 7.3.0
The CXX compiler identification is GNU 7.3.0

But when I try to build the code, this is what I get:

However, the library exists:

So, what am I doing wrong? What should I do to get it working properly?
I tried the answer of #squareskittles, and I got this when tried to build:

Your CMake is adding the dcmtk include directories like this:
SET(DCMTK_DIR /usr/local/include/dcmtk)
INCLUDE_DIRECTORIES(${DCMTK_DIR}/include)
which evaluates to this path:
/usr/local/include/dcmtk/include
Your main.cpp file then includes dcmtk/config/osconfig.h, which (combining the two paths) suggests the header is located here:
/usr/local/include/dcmtk/include/dcmtk/config/osconfig.h
This doesn't seem correct. Try including only /usr/local/include in your CMake file instead:
INCLUDE_DIRECTORIES(/usr/local/include)
As a side note, CMake provides a Find Module for the DCMTK, so it will attempt to find the library and set some variable for you. You could try something like this, but depending on your CMake version, you may have varying results:
cmake_minimum_required(VERSION 2.8)
PROJECT(test1DCMTK)
find_package(DCMTK REQUIRED)
add_executable(${PROJECT_NAME} main.cpp)
SET(DCMTK_DIR /usr/local/include/dcmtk)
ADD_DEFINITIONS(-D_REENTRANT)
# Use the INCLUDE_DIRS variable populated by the DCMTK find module.
INCLUDE_DIRECTORIES(${DCMTK_INCLUDE_DIRS})
# Use the LIBRARIES variable populated by the DCMTK find module.
TARGET_LINK_LIBRARIES(test1DCMTK ofstd ${DCMTK_LIBRARIES})
If this successfully finds DCMTK, the DCMTK_INCLUDE_DIRS will likely contain all necessary include directories for DCMTK, not only the include directory you have added manually. This may help resolve the compiler errors you are seeing.

I also faced the same problem while trying to build OpenCV 3.2.0 using mingw32 on Windows10. I searched a bit to find a fix on Github for similar problem. It said the problem was:
MinGW defined _CRITICAL_SECTION and _RTL_CRITICAL_SECTION as two separate (equivalent) structs, instead of using typedef
So, you have to add another typedef GTEST_CRITICAL_SECTION for _CRITICAL_SECTION and _RTL_CRITICAL_SECTION and use this typedef for either case.
Here is what to do :
Edit "ts_gtest.h" which is inside "opencv\sources\modules\ts\include\opencv2\ts\"
Replace this line (probably line 723)
// assuming CRITICAL_SECTION is a typedef of _RTL_CRITICAL_SECTION.
// This assumption is verified by
// WindowsTypesTest.CRITICAL_SECTIONIs_RTL_CRITICAL_SECTION.
struct _RTL_CRITICAL_SECTION;
with
#if GTEST_OS_WINDOWS_MINGW
// MinGW defined _CRITICAL_SECTION and _RTL_CRITICAL_SECTION as two
// separate (equivalent) structs, instead of using typedef
typedef struct _CRITICAL_SECTION GTEST_CRITICAL_SECTION;
#else
// Assume CRITICAL_SECTION is a typedef of _RTL_CRITICAL_SECTION.
// This assumption is verified by
// WindowsTypesTest.CRITICAL_SECTIONIs_RTL_CRITICAL_SECTION
typedef struct _RTL_CRITICAL_SECTION GTEST_CRITICAL_SECTION;
#endif
Replace this line (probably on line 3060 before your edit - line number would have changed as you modified first part)
_RTL_CRITICAL_SECTION* critical_section_;
with
GTEST_CRITICAL_SECTION* critical_section_;
These two changes should fix your above error.
It was fixed by using TDM-gcc mingw compiler.

Cassandra cpp-driver compile error

I'm trying to install Cassandra cpp-driver in Ubuntu.
I've done the steps specified in DataStax C/C++ Driver for Apache Cassandra (Beta), but i keep getting the following compile error.

I've already fixed this compile errors in Cassandra cpp-driver, by down-versioning libuv to version libuv-0.10, the compile errors will be gone.
It seems that the latest updates for libuv is not yet supported by Cassandra cpp-driver.
