Hi,

 

I’m getting a problem building master-2.4.  The repro steps are:

 

• Deleted all files in the WS code tree
• Deleted all files in the wsbuild64 directory
• Check out master-2.4.
• Do git pull to refresh
• Run the prep cmake command (as below)
• I get errors complaining about PowerShell

CMake Error at CMakeLists.txt:78 (find_package):

  By not providing "FindPowerShell.cmake" in CMAKE_MODULE_PATH this project

  has asked CMake to find a package configuration file provided by

  "PowerShell", but CMake did not find one.

 

  Could not find a package configuration file provided by "PowerShell" with

    PowerShellConfig.cmake

    powershell-config.cmake

 

  Add the installation prefix of "PowerShell" to CMAKE_PREFIX_PATH or set

  "PowerShell_DIR" to a directory containing one of the above files.  If

  "PowerShell" provides a separate development package or SDK, be sure it has

  been installed.

I did a search and found that Graham B had helped me with the same problem last December but on Windows 7 (I’m now on Windows 10).  This is on a dev VM that I haven’t changed other than last week the VM installed Windows Updates.  I have been building WS on the same VM although I switch branches quite a lot as I have a couple of private local branches.

 

Should I be able to see the file FindPowerShell.cmake in the source tree and if so where?

 

Cheers…Paul

 

PowerShell should always be on your Windows path, you really have to go out of your way to get rid of it.

The FindPowerShell.cmake module should be in <source_dir>\cmake\modules\

It's very simple as powershell.exe should be on your path, usually in<Windir>\System32\WindowsPowerShell\v1.0.
