RE: EPICS build problem

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

Hi,

Can you just try the following to check your compiler is working correctly

From a new command window run       vcvarsall.bat  x64     which for me is running the command

        "C:\Program Files\Microsoft Visual Studio\2022\Enterprise\VC\Auxiliary\Build\vcvarsall.bat" x64

But your visual studio may be a different version or in a different location. It should reply with something like

    **********************************************************************
    ** Visual Studio 2022 Developer Command Prompt v17.11.5
    ** Copyright (c) 2022 Microsoft Corporation
    **********************************************************************
    [vcvarsall.bat] Environment initialized for: 'x64'


Now create a simple    test.c     file containing

#include <stdio.h>
int main(int argc, char* argv[])
{
    printf("Test\n");
    return 0;
}


Now try and build this file with

    cl test.c

which should generate output to screen like


C:\Users>  cl test.c
Microsoft (R) C/C++ Optimizing Compiler Version 19.41.34123 for x64
Copyright (C) Microsoft Corporation.  All rights reserved.

test.c
Microsoft (R) Incremental Linker Version 14.41.34123.0
Copyright (C) Microsoft Corporation.  All rights reserved.

/out:test.exe
test.obj

if that works try running the executable

C:\Users> test.exe
Test
    

Regards,

Freddie
