I am facing a very frustrating access denied error without any other information.

I have git clone 'd a repository to a folder, naimly to ~\Desktop\bempp. When i try to cmake by typing in the cmd cmake -DCMAKE_INSTALL_PREFIX=<install_dir> .. I get an error message Access denied. install_dir is ~\Desktop\bempp . Instructions are here under the title compiling bem++:http://www.bempp.org/installation.html

I also tried to cmake with the gui (it succeeded), then build with visual studio (succeeded again), but once more when I try to run it I get: Unable to start program ~\bem\x64\Release\ALL_BUILD access denied.

I tried to remove the read-only nature of the folder and the subfolders, but they come back automatically. After more googling it turns out that attrib has to be used:

my call is: 

attrib -r +s C:\Users\nempa001\Desktop\bempp /s /d

The call simply does not work. Apart from not working recursively as said in each description page (check this) https://www.lifewire.com/attrib-command-2625802 , even if I attrib +s each one of the folders in the path shown in the Visual studio message (these attrib call succeed, I check it through attrib ), I still get the same error from Visual Studio.

I am the owner of the folder in properties and also I have full control rights and there is system endpoint center protection on my computer(maybe irrelevant). This whole situation makes zero sense.

Am I towards the right direction? I am totally out of ideas, can anyone propose a solution?

  • Out of security reasons there are some folders in Windows a program can only change when the program is running with administrator privileges. Did you try to right click on `cmd.exe` and use `Run as admimistrator`? I had a similar problem and used [`PrivBar`](https://blogs.msdn.microsoft.com/aaron_margosis/2004/07/24/privbar-an-ieexplorer-toolbar-to-show-current-privilege-level/) to check my/the programs privilege level. Otherwise see ["How do you run CMD.exe under the Local System Account?"](https://stackoverflow.com/questions/77528) – Florian Jan 31 '18 at 20:08
  • yes, I have found that. However, I can run it as administrator and nothing changes – Paramar Feb 01 '18 at 11:44
  • Could you please add your error message(s) and more information on the environment your running in? I tried to reproduce your problem and with CMake Visual Studio generator I get the following errors: `Could NOT find PkgConfig (missing: PKG_CONFIG_EXECUTABLE)` and `Environment scripts not implemented on non-UNIX systems`. So something is missing in your problems description to enable us to reproduce your problem. – Florian Feb 06 '18 at 20:37
  • Florian thanks for your help. It turns out if your system is non unix, the cmake is interrupted. Nothing to be done, the error is pretty self explanatory and a dead-end for a windows machine as it seems. – Paramar Feb 08 '18 at 20:02
