opencv build error in windows: no rule to make target [closed]
Hi everyone. I can't create opencv jar with extra modules. I run cmake-gui,then I run "make" command in build file, I take error which no rule to make target. Can you help me, why I can create jar ? I take this logs:

since you're using VS2017, cmake will generate a
opencv.slnfile in the build folder, not a makefile.open that with VS and build the INSTALL project. (instead of running "make")
Thanks for answer. I do build INSTALL project in VS, but .dll files created in build\install\x64\vc15\bin and .lib files created in build\install\x64\vc15\lib. build\install\java and build\install\bin are empty. There is no .jar files in build directory. Why I create .jar files for using Intellij Idea?
really ? nothing in C:/Users/mehmetdu/Desktop/opencv_extra/build/install/java ?
try to run the INSTALL project again, and carefully check the console log there
also, maybe you should use BUILD_SHARED_LIBS=OFF in cmake, so it won't depend on opencv dll's later
thank you, I take error that is "Unable to find a javac compiler" in VS build INSTALL,so jar isn't created. Last step, I can create opencv341.jar but I can't create opencv_java341.dll. Why I create .dll file?
"so jar isn't created"
"I can create opencv341.jar"
what now ? is it or isn't it created ?
I can create opencv400.jar and opencv_java400.dll in build\install\java directory, but in intellij idea project, I take error that "lib\opencv_java400.dll: Can't find dependent libraries". Is not there some libs in dll? What is reason?
if you have built it with BUILD_SHARED_LIBS=ON, it means, that opencv_java400.dll is dependant on all those other opencv dlls, and that you need to put the folder containing those on the PATH , so your prog can find them at runtime.
It works, thank you very much :) I spent 3 days for this. I think, with extra module release must put opencv webpage, a lot of people try to work build extra modules, a lot of times is spent.
actually, it's even mentioned here: https://docs.opencv.org/master/d9/d52...
but yes, it's not easy at all. ;(
