If I use those coming with the mingw64 proposed by a linux package manager, manually linking a betterC object containing a simple main fails with an error about "undefined mainCRTStartup".

But if I use those coming from ldc2 64 bit windows distribution that works perfectly.

command is

$ lld-link /NOLOGO /OPT:REF /OPT:ICF /SUBSYSTEM:WINDOWS /ENTRY:mainCRTStartup\
 /errorlimit:0 /OUT:a.exe /LIBPATH:$LP\
 /DEFAULTLIB:$DL\
 .main.o

with LP either

• /usr/x86_64-w64-mingw32/sys-root/mingw/lib (not working version)
• /home/xx/bin/ldc2-/lib/mingw (copied from the ldc2 win release)

and DL either

• libvcruntime140_app.a (not working version)
• vcruntime140 (ldc2 one)

So I wonder where do your mingw libraries come from ?

They're from https://github.com/ldc-developers/mingw-w64-libs; see its README.md for details.

thanks, the work done on your version of vcruntime140.lib is valuable.
