Chapter 8, Recipe 3: Permission denied whe Renaming

[byxrolland]

Hi, I am learning CMake using your book.

In Chapter 8, Recipe 3, when I build the project using cmake --build . inside the build folder, somewhere after the downloading is completed, the build failed. And it gave out the message:

-- extracting... [tar xfz]
-- extracting... [analysis]
-- extracting... [rename]
CMake Error at /mnt/c/Ubuntu/cmake-cookbook/chapter-08/recipe-03/c-example/build/subprojects/Stamp/fftw3_external/extract-fftw3_external.cmake:51 (file):
  file RENAME failed to rename

    /mnt/c/Ubuntu/cmake-cookbook/chapter-08/recipe-03/c-example/build/subprojects/Source/ex-fftw3_external1234/fftw-3.3.8

  to

    /mnt/c/Ubuntu/cmake-cookbook/chapter-08/recipe-03/c-example/build/subprojects/Source/fftw3_external

  because: Permission denied



external/upstream/fftw3/CMakeFiles/fftw3_external.dir/build.make:90: recipe for target 'subprojects/Stamp/fftw3_external/fftw3_external-download' failed
make[2]: *** [subprojects/Stamp/fftw3_external/fftw3_external-download] Error 1
CMakeFiles/Makefile2:145: recipe for target 'external/upstream/fftw3/CMakeFiles/fftw3_external.dir/all' failed
make[1]: *** [external/upstream/fftw3/CMakeFiles/fftw3_external.dir/all] Error 2
Makefile:83: recipe for target 'all' failed
make: *** [all] Error 2

The line that cause the error (.../cmake-cookbook/chapter-08/recipe-03/c-example/build/subprojects/Stamp/fftw3_external/extract-fftw3_external.cmake:51 (file): is

file(RENAME ${contents} ${directory})

I tried sudo cmake --build . It didn't help. As you can see, I am operating on WSL.

Would you please help fix this issue? Thanks.

Sorry that you had to wait so long for a reaction. I have never tried WSL but it would be good for me to test it out. I will need to try it on a Windows virtual machine since my laptop runs Linux.
