Hi Timo,

Here is my report. Run the two MakeLibs.bat files to create the import libraries for both of the 32-bit and 64-bit architectures :

Code Select Expand

set p=E:\PellesC\bin
.
.
%p%\Polib.exe /MACHINE:x86 /OUT:ucrt.lib api-ms-win-crt-conio-l1-1-0.lib api-ms-win-crt-convert-l1-1-0.lib api-ms-win-crt-environment-l1-1-0.lib api-ms-win-crt-filesystem-l1-1-0.lib api-ms-win-crt-heap-l1-1-0.lib api-ms-win-crt-locale-l1-1-0.lib api-ms-win-crt-math-l1-1-0.lib api-ms-win-crt-multibyte-l1-1-0.lib api-ms-win-crt-process-l1-1-0.lib api-ms-win-crt-runtime-l1-1-0.lib api-ms-win-crt-stdio-l1-1-0.lib api-ms-win-crt-string-l1-1-0.lib api-ms-win-crt-time-l1-1-0.lib api-ms-win-crt-utility-l1-1-0.lib
Polib reports some warning messages bot they are not harmful :

That silly test used only ucrtbase.dll, as those Api Stub forwanders mostly point to it.
Making ucrt.lib is more demanding, as have to collect those (stupid) forwanders are mostly used for versioning, and with no code.

Hi Jack,

It's easy to build and use the import library for ucrt :
