| Subject: | GNU Make 4.4.1 under Windows does not completely build the EPICS base 7 |

Hello!
I followed the instructions "Installation using plain Windows and the Visual Studio compilers" (https://docs.epics-controls.org/en/latest/getting-started/installation-windows-plain.html) to build the EPICS Base 7.0.7 under Windows 10. Although I had already done this successfully many times, this time the Make process always aborted with the pvAccess tools. So I took a closer look and found out the following. The current Perl Strawberry distribution (5.38.0.1) comes with Make version 4.4.1. This Make always aborts after compiling "base\modules\pvData\src\json\parseinto.cpp". The "parseinto.obj" is still created successfully. The "print.obj" should then be compiled. But instead, Make only outputs "obj = '' " and fails in the subsequent link process due to the missing "print.obj".
However, if I build the same sources with Make version 4.2.1, the entire build process runs without errors and the pvAccess tools are also built completely. All works fine.
Unfortunately I could not find out why Make 4.4.1 fails to compile "parseinto.cpp" and Make 4.2.1 has no problems with it.
Best,
Carsten
