C/C++ configuration problem in android studio 4 after gradle sync

I am trying to integrate native (C++) OpenCV code into my project. I am following this project on github. After I click refresh linked C++ projects the compiler exits with exit code 1.

The folder containing open-cv sdk had a space in its name. Removing the space solved the error.

android studio 3.2 initial build error (testCCompiler.c file not found, windows 10)

today I installed android studio 3.2.1 on my windows 10 PC at home.
(I have installed a previous version 3 months ago but I unstalled it before installing new one, because it had similar problem I remember)
When I install the program, it is supposed to build itself but it fails with below messages.

I saw similar question on SO but it's not exactly same to my situtation and I tried the suggestions(Refresh linked C++ project) and it didn't work. and some advices are for linux. The first error message is 'can't find cCompilerProgram.c' for cmake.(When I look into the folder, the file is not actuall there) How can I solve this? By the way, my login name on windows 10 is 'Chan Kim' with space in the middle. Can it have any problem? I guess the testCCompiler.c file is what the build process make during the build.
Any suggestion will be deeply appreciated.

the error actually reads:
-- Check for working C compiler: .../prebuilt/windows-x86_64/bin/clang.exe -- broken
this seems related.

My problem was that my login name in windows10 was 'Chan Kim' and the error log shows it cannot parse down the folder name containing 'Chan Kim' and it cannot process space in the folder name. So I created a new account 'ckim' and did the same (it downloads huge amount of data under C:\Users\ckim this time) and everything works fine.
So DON'T USE USERNAME WITH SPACE whne using android studio. (I don't know why the book and android studio doesn't warn about this situtation. I read in the book, if my login name contains Korean characters, it won't work. but it turns out login name with space doesn't work either).
Hope this be useful for someone.
ADD : I tried configuring the SDK again using Users\ChanKim\AppData folder and it works too. (originally it was using Users\Chan Kim\AppData)

I had the same Problem. I hope i can help u here.
Try to create a new project and change the project location. Its important, that the new project location, contain NO whitespace. Gradle cannot sync, if there is whitespace.

Android Studio NDK Build command failed (Missing c Compiler?)

I have tried several days installing the NDK into Android Studio but it always gives me an error message saying that the build failed and I should install a c compiler. I installed the NDK via the SDK Manager by checking the NDK and C Make.
I have already tried completely reinstalling Android Studio and the NDK but that did not work as well -same error.
Something maybe worth mentioning is that if I do not check the C++ support during the project creation there are no errors(but no c++ support too:D).
What should I do because it kills my workflow?
Thank you very much

I'm trying to use JNI to link an existing C++ project to Android Studio. I've also tried to load all of the provided NDK-JNI sample projects. Everything with JNI/Cmake is unable to Gradle Sync, failing with the same error:
Build command failed.

The system cannot find the path specified.
ninja: build stopped: subcommand failed.
CMake will not be able to correctly generate this project.
I have all necessary SDK tools installed. I've tried using GCC instead of clang. Thanks for your help!

The main error message is:
The system cannot find the path specified.
Note that above some places use / as path separator:
"C:/Users/Alex/AppData/Local/Android/sdk/ndk-bundle/toolchains/llvm/prebuilt/windows-x86_64/bin/clang.exe"
and have run successfully. And this line:
C:\Users\Alex\AppData\Local\Android\sdk\ndk-bundle\toolchains\llvm\prebuilt\windows-x86_64\bin\clang.exe
Seems to have failed. I guess the problem is the \. Try find where this path is defined, maybe in the IDE options, configuration files or Makefiles, then modify it may solve the problem.

Its because of clang version mismatch
check clang version you have and what minimum clang version Android Application needed!
