Building Error with Eclipse on Win7 64bit
Hello, I'm new to OpenCV and try to build OpenCV (without any special plugin) with Eclipse on my Laptop with Win7 64bit. For this I followed the "Installtion in Windows"-Tutorial, using TDM-GCC 32bit Compiler and CMake 2.8.12.2 ( Version 3.0.0 gives me an Error with CMP0026). In CMake I choose "EclipseCDT-MinGW Makefile", make my selection, press configure and then generate.
Btw. is it ok, if there are missing paths to modules I do not want to use? E.g. CLAMDBLAS or Java Path)?
After I have opened the generated project with Eclipse(Import exiting code with Makefile) I try to start building, but after a few seconds I get the following Error:
Errors occurred during the build. Errors running builder 'CDT Builder' on project 'OpenCVBuilding'. Internal error building project OpenCVBuilding configuration Default Generated resource conflict: two resources of the same name: /OpenCVBuilding/Default/[Targets]/[lib] zlib/Source Files/zutil.o generated by different tools tool1: GCC C Compiler tool2: GCC C Compiler

So I tried building OpenCV on my Desktop using TDM-GCC 64bit (everything else unchanged) with the same Error. Due to this I choose a MinGWMakefile in CMake and directly use mingw32-make.exe from TDM-GCC(both 32bit and 64bit). I also tried building OpenCV with Code::Blocks but both (Codeblocks and wingw32-make) gave me this Error:
