RE: EPICS build problem

[Freddie Akeroyd - STFC UKRI via Tech-talk <tech-talk at aps.anl.gov>]

Hi,

The windows.bat / win32.bat files just run vcvarsall.bat, set EPICS_HOST_ARCH and add perl to the PATH, so are just convenient shortcuts and not strictly necessary

When vcvarsall.bat is run it needs an argument to tell it the build architecture, and this needs to match your intended EPICS_HOST_ARCH.   So try 

    vcvarsall.bat x64
    set EPICS_HOST_ARCH=windows-x64

for a 64bit build. If you needed a 32bit built it would be:

    vcvarsall.bat x86
    set EPICS_HOST_ARCH=win32-x86

Regards,

Freddie

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!c1lDfN5t1iRCDMbpVMwmC-GZ5qPmuQYEH9RJybLPsLuQGWe9a5pN0eCOFX1yf2XlZNTPHS1tQ4y-UlBgaEDkeH_vT8mEQyTlQG4$ .

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?
