Hello everyone! This is my first post. I'm having trouble with compiling OpenCV in openSUSE Tumbleweed. I get an error when I try to configure with both cmake-gui and cmake. Error is:

CMake Error at cmake/OpenCVDetectCXXCompiler.cmake:85 (list):
  list GET given empty list
Call Stack (most recent call first):
  CMakeLists.txt:109 (include)


CMake Error at cmake/OpenCVDetectCXXCompiler.cmake:86 (list):
  list GET given empty list
Call Stack (most recent call first):
  CMakeLists.txt:109 (include)


CMake Error at cmake/OpenCVDetectCXXCompiler.cmake:89 (math):
  math cannot parse the expression: "*100 + ": syntax error, unexpected
  exp_TIMES, expecting exp_OPENPARENT or exp_NUMBER (1)
Call Stack (most recent call first):
  CMakeLists.txt:109 (include)

Following line after the error is that:

Detected version of GNU GCC:  ()

Is it meaning that something is wrong with the GCC, because there should be version written inside the brackets?

I don't know much about cmake to solve this problem, so unfortunately I'm stuck.

cmake version 3.2.3 gcc version 5.1.1 20150622 [gcc-5-branch revision 224722] (SUSE Linux) Itried both opencv-3.0.0 and opencv-master but got same error.

sir, this error puzzled me for some hours and i found this github page. i will take OpenCV2.4.13 as example, in file opencv2.4.13/cmake/ OpenCVDetectCXXCompiler.cmake, u have to change "dumpversion" to "dumpfullversion"

explanation is that in gcc with higher version, dumpversion function can't get true full version number of compiler so that cmake progress will fail.
