My guess the reason why the core lib is empty is because of one of the changes I made to the files. #endif in …\opencv-4.7.0\modules\core\src\softfloat.cpp #elif (i64_fromNaN = i64_fromNegOverflow) #if (i64_fromNaN != i64_fromPosOverflow) || (i64_fromNaN != i64_fromNegOverflow) When trying to run opencv for embarcadero C++ builder 10.3 I changed a few things in the folder of OpenCV:Įrror: use of undeclared identifier ‘uintptr_t’ = add #include in …\opencv-4.7.0\3rdparty\ittnotify\include\ittnotify.hĮrror: use of undeclared identifier ‘lrintf’ = add #include in …/opencv-4.7.0/modules/core/include\opencv2/core/fast_math.hppĮrror: unknown type name ‘FILE’ = add #include in …/opencv-4.7.0/modules/core/include\opencv2/core/operations.hppĮrror: use of undeclared identifier ‘llvm’ = comment it out and make it return 0 instead in …/opencv-4.7.0/modules/core/include\opencv2/core/hal/intrin.hppĮrror: token is not a valid binary operator in a preprocessor subexpression in #if (i64_fromNaN != i64_fromPosOverflow) || (i64_fromNaN != i64_fromNegOverflow) = comment out: Did I do something wrong with the CMake command or is there another problem? I found out that I get this error because the lib file for opencv_core is completely empty. Is the error because I use WIN32 or did I not correctly add the lib files to the project? Sadly the project I need to add OpenCv to is created in WIN32 and want to see if it can be possible to be added for WIN32. Error: Unresolved external 'cv::Mat.' referenced from C:\USERS\XANDERV\DOCUMENTS\GIT\APPLICATION SOFTWARE\OPENCVTEST\WIN32\DEBUG\MAIN.OBJ But when I want to test if I can use OpenCV by using a simple line of code Mat frame I get the following error: Error: Unresolved external 'cv::Mat::Mat()' referenced from C:\USERS\XANDERV\DOCUMENTS\GIT\APPLICATION SOFTWARE\OPENCVTEST\WIN32\DEBUG\MAIN.OBJ After that I added all the lib files from the staticlib folder of the install folder to the project folder of the project I want to test. In …->Paths and Directories->System Include Path I added the install folder of the build folder and the include of that install folder. ![]() From the build folder I added the lib folder to tools->options->Language->C++ Options->Paths and Directories->Library Path. Thanks for the reply, after adding -DBUILD_opencv_apps=OFF it built correctly in the build folder. This error occurs every time it wants to link exe files. But when using ninja I don’t get it working like I explained in this problem. I don’t get the error when I use the ninja command like it is explained here. I always get that error when trying to use the make install command and when trying to search if it is on my computer, it can’t be found anywhere. ![]() ![]() ** error 1 ** deleting apps\annotation\CMakeFiles\opencv_annotation.dir\all ** error 2 ** deleting bin\opencv_annotationd.exe "\"C:\\Program Files (x86)\\Embarcadero\\Studio\\20.0\\bin\\ilink32.exe\"" Incremental Link 6.90 Copyright (c) 1997-2017 Embarcadero Technologies, Inc.įatal: Unable to open file '.LIBOPENCV_CORE453D.LIB'īcc32x.exe: error: linker command failed with exit code 2 (use -Xdriver -v to see invocation) InstalledDir: C:\Program Files (x86)\Embarcadero\Studio\20.0\binīcc32x.exe: warning: argument unused during compilation: '-nobuiltininc' \.\bin\opencv_annotationd.exeĮmbarcadero C++ 7.40 for Win32 Copyright (c) 2012-2018 Embarcadero Technologies, Inc.Įmbarcadero Technologies Inc.
