Hello,

I have a problem during linking my umat() procedure written in C++.
I am using Windows 10, Abaqus 2022 and Microsoft Visual Studio 2022 Community (compiler cl version 19.36.32537 for x64).
Compilation completes fine but the linker aborts with the following error messages.

----------------------------------------------------------------

Abaqus Error: Problem during linking - Abaqus/Standard User Subroutines.

This error may be due to a mismatch in the Abaqus user subroutine arguments.

These arguments sometimes change from release to release, so user subroutines

used with a previous release of Abaqus may need to be adjusted.

Abaqus/Analysis exited with errors

----------------------------------------------------------------

These errors occurs particularly when I am trying to construct an object as static one within the umat() body. There are no such problems with initializing static primitive types or non-static objects; jobs run and finish almost fine in their cases (except for "warning LNK4210: .CRT section exists; there may be unhandled static initializers or terminators").

Passing /verbose:lib into the linker's options reports that the mentioned msvcrt.lib is taken from "E:\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.36.32532\lib\x64\msvcrt.lib". This path looks like OK for me.

The compiler and linker are called via Abaqus Commands' terminal with the following options (specified in "E:\SIMULIA\EstProducts\2022\win_b64\SMA\site\win86_64.env").

Is there a way to fix the above problems (or, perhaps, am I misunderstood something)?
I am hope for your help.
