Hi all,
I am using Cygwin in Windows 7 and am having some trouble with building my OpenCV library. Here are my steps so far:
- I downloaded the most recent stable version of the source (3.00)
- Navigated to my empty desired build directory and called cmake <path to="" the="" source="">
- Called make from within the build directory
- This returns an error around 30% that 'close() is not declared in the scope of some function' in system.cpp, so I updated system.cpp to #include <unistd.h>.
This fixed that initial error, however a new error is causing issues now that I cannot seem to resolve. I wonder if my fix to the first issue is causing this seg fault, but I am not sure why it would. Here is the error message I am receiving:
[ 30%] Linking CXX shared library ../../bin/cygopencv_core-3.0.dll
collect2: fatal error: ld terminated with signal 11 [Segmentation fault], core dumped
compilation terminated.

Here is my configuration for my build, if that is helpful:
-- General configuration for OpenCV 3.0.0 =====================================
-- Version control: unknown
--
-- Platform:
-- Host: CYGWIN 2.2.1(0.289/5/3) x86_64

-- CMake build tool: /usr/bin/make.exe
-- Configuration: Release

Thanks in advance! I would really appreciate any help I can get
