Qt 6.3.1 Cannot Find <directory>: Permission Denied

[Simplexity]

Using Qt 6.3.1. Trying to build a github cloned libzip on windows 10. The CMakeLists.txt parses fine and have set the paths to the dependent zlib libraries and includes in the CMakeLists.txt file. I successfully build the zlib library in another Qt project without error.

I simplified the path to D:/ctest, to ensure I wasn't making a typo, but I still get the permission denied error. I turned off the virus protection and rebooted the machine.

Any ideas please?

Compilation output

[ChrisW67]

The error message tells you that D:/ctest does not exist. It is right: the path separator on Windows is the backslash d:\ctest. CMake is not a Qt application so does not automagically convert slashes for you.

[Simplexity]

Thanks. If you use windows backslashes \ in the CMakeFiles.txt file, you get this error, when making:

Other posts previously alerted me, that I need to use forward slashes, even though I am on windows.

[Christian Ehrlicher]

It can be either 'C:\test' or 'C:/test'. But that's not the problem. Please show how you use those two cmake variables later on. You're doing something wrong there.

@Christian-Ehrlicher

Not sure if you wanted to see the CMakeLists.txt, but here is the compiler output:

A problem seems to be with my setting the ZLIB_LIBRARY path to D:/something, because if I set it to /ctest, then I get a ninja error:
ctest needed by lib/libzip.dll, missing and no known rule to make it:

[SimonSchroeder]

@Simplexity said in Qt 6.3.1 Cannot Find <directory>: Permission Denied:

cmd.exe /C "cd . && D:\Qt\Tools\mingw1120_64\bin\gcc.exe -g -shared -o lib\libzip.dll -Wl,--out-implib,lib\libzip.dll.a -Wl,--major-image-version,5,--minor-image-version,5 [lib/CMakeFiles/zip.dir/*.obj] -ladvapi32 -lbcrypt D:/ctest -lkernel32 -luser32 -lgdi32 -lwinspool -lshell32 -lole32 -loleaut32 -luuid -lcomdlg32 -ladvapi32 && cd ."

This command only shows D:/ctest which tells the linker to link to a file ctest in the directory D:/. What you need instead is -LD:/ctest. Please provide the full CMakeLists.txt (as text, not as screenshot!) so we can figure out why this problem occurs in the generated command.

@SimonSchroeder

Many thanks, here is the CMakeLists.txt I am using. It is the current version from https://github.com/nih-at/libzip, where I have added the CMake set commands to set the ZLIB variables.

@Simplexity said in Qt 6.3.1 Cannot Find <directory>: Permission Denied:

This answer on StackOverflow https://stackoverflow.com/questions/46530617/cmake-set-zlib-path says:

Furthermore, ZLIB_LIBRARY needs to point to the library itself. Here is my final build line which works:

cmake -DZLIB_INCLUDE_DIR=d:\mystuff\zlib-1.2.11 -DZLIB_LIBRARY=d:\mystuff\zlib-1.2.11

Can you show us the contents of D:\ctest?

@SimonSchroeder

I think I now have the solution. My problem was:

• Running CMake in project libzip, issues errors that make it look as though the user needs to set path type variables, ZLIB_LIBRARY and ZLIB_LIBRARY_DIR.
• If you set these variables to a path like I did, you then get the errors "cannot find...permission denied"etc.
• The libzip CMake file has , find package ZLIB.
• I didnt notice that findZLIB.cmake is actually a CMake file that is installed in the Qt directories i.e. in my case, not provided by the github clone in my root project!
  c:/Qt/Tools/CMake^4/share/cmake-3.23/Modules

#[=======================================================================[.rst:
FindZLIB

Find the native ZLIB includes and library.

IMPORTED Targets
^^^^^^^^^^^^^^^^

.. versionadded:: 3.1

This module defines :prop_tgt:IMPORTED target ZLIB::ZLIB, if
ZLIB has been found.

Result Variables
^^^^^^^^^^^^^^^^

This module defines the following variables:

::

ZLIB_INCLUDE_DIRS - where to find zlib.h, etc.
ZLIB_LIBRARIES - List of libraries when using zlib.
ZLIB_FOUND - True if zlib found.

::

ZLIB_VERSION_STRING - The version of zlib found (x.y.z)
ZLIB_VERSION_MAJOR - The major version of zlib
ZLIB_VERSION_MINOR - The minor version of zlib
ZLIB_VERSION_PATCH - The patch version of zlib
ZLIB_VERSION_TWEAK - The tweak version of zlib

.. versionadded:: 3.4
Debug and Release variants are found separately.

Backward Compatibility
^^^^^^^^^^^^^^^^^^^^^^

The following variable are provided for backward compatibility

::

ZLIB_MAJOR_VERSION - The major version of zlib
ZLIB_MINOR_VERSION - The minor version of zlib
ZLIB_PATCH_VERSION - The patch version of zlib

Hints
^^^^^

A user may set ZLIB_ROOT to a zlib installation root to tell this
module where to look.

• Once you set ZLIB_ROOT to the path where you have the dependencies (.dll and headers) (I set it to D:/ctest) then the CMake parses find and then you can successfully build.
