2015-06-25 07:19:44 -0600 | asked a question | std::bad_alloc in traincascade Hey Guys, I tried to run the opencv_traincascade program with following command under Win7 64bit:
When running this command I had 2530 mb free ram and more than 50 GB free space on my harddrive and got this error:
I also tried it in a VM with Linux Mint but got also a memalloc error where it says that it can't alloc 2GB of data, even if I had enough space on my virtual harddrive. I hope someone knows this problem aswell as a solution for it. NG Dr. Console |

2015-06-23 15:01:15 -0600 | asked a question | imshow: Assertion failed (size.width>0 && size.height>0) Hey guys, here's the next error I encountered ... When I tried this code to test the installation: I get this error inside the app console:
The image used is the standart Win7 demo picture of a jellyfish renamed to test.png and put into the project folder. I hope that someone can help me, maybe it's just a change from opencv 2 to 3 but I don't know. My System is Win7, Code::Blocks 13.12 and OpenCV 3. Compiler is mingw. NG Dr. Console |

2015-06-22 22:36:37 -0600 | asked a question | Problem at compiling (libopencv_core300.dll not found) Hey guys, I'm just installing OpenCV for a project controling a SMD mounting machine but I'm not abled to comile the Project for usage with Code::Blocks with mingw. I'm using this tutorial: http://kevinhughes.ca/tutorials/openc... Everytime I'm running the command "mingw-make" it stops at 31% with following message: [ 31%] Linking CXX shared library ....\bin\libopencv_core300.dll c:/mingw/bin/../lib/gcc/mingw32/4.8.1/../../../../mingw32/bin/ld.exe: cannot fin d -lRunTmChk collect2.exe: error: ld returned 1 exit status modules\core\CMakeFiles\opencv_core.dir\build.make:1286: recipe for target 'bin/ libopencv_core300.dll' failed mingw32-make[2]: * [bin/libopencv_core300.dll] Error 1 CMakeFiles\Makefile2:1654: recipe for target 'modules/core/CMakeFiles/opencv_cor e.dir/all' failed mingw32-make[1]: * [modules/core/CMakeFiles/opencv_core.dir/all] Error 2 Makefile:148: recipe for target 'all' failed mingw32-make: * [all] Error 2 My Systems is WIN7 64bit and the newest versions of cmake, mingw, opencv and Code::Blocks Hope someone can help me. NG from Germany Dr. Console EDIT: Found a solution, it's a mingw bug... I needed to disable IPP and comment out the line 'add_extra_compiler_option(-Werror=non-virtual-dtor)' in C:opencv\sources\cmake\OpenCVCompilerOptions.cmake So the make command worked. |
