Re: EPICS build problem

Hi Freddie,

I've followed this part of the tutorial:
-------------------------------------------
Download the distribution from e.g. 
https://urldefense.us/v3/__https://epics-controls.org/download/base/base-7.0.4.1.tar.gz__;!!G_uCfscf7eWS!f_jetzd-K2r1G-0E_Zv9zjtYiGo8BXPMtqLcSDchZBqTZpbQiAip-iIgDvINnl8VtGXPn7xXVeNDYSAvmHfXSULPBoc$ .
Unpack it into a work directory.

Open a Windows command prompt and change into the directory you unpacked 
EPICS Base into.
Note: The complete path of the current directory mustn’t contain any 
spaces or parentheses. If your working directory path does, you can do 
another cd into the same directory, replacing every path component 
containing spaces or parentheses with its Windows short path (that can 
be displayed with dir /x).
Set the EPICS host architecture EPICS_HOST_ARCH (windows-x64 for 64bit 
builds, win32-x86 for 32bit builds).
Run the vcvarsall.bat script of your installation (the exact path 
depends on the type and language of installation) to set the environment 
for your build.
Run make (or gmake if using the version from Strawberry Perl).
---------------------------------------------
When i cd to my folder, and typed "where cl" it doesnt' return anything 
not even after i ran the vcvarsall.bat. I didnt' ran the windows.bat 
because it wasn't written.
Should i do it directly from the folder?
