RE: EPICS build problem

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

Hi,

In the startup directory of epics there are two bat files  "win32.bat" and "windows.bat" - which did you use to setup the compiler path etc. ?  win32.bat choses the compiler for 32bit builds and windows.bat for 64bit builds. Your EPICS_HOST_ARCH environment variable is set for a 64bit builds, but the error message suggests your build may be using the 32bit compiler instead as the linker cannot target x64. If you type

    where cl

do you see a path with x64 in it like

    C:\Program Files\Microsoft Visual Studio\2022\Enterprise\VC\Tools\MSVC\14.41.34120\bin\Hostx64\x64\cl.exe

Or do you see x86 present instead?

Regards,

Freddie

Thanks in advance for the help. I made the log for make and also i can tell that i'm following by letter the tutorial that i've linked to download and build epic base. I've installed perl and make manually.

Best regards.
