Using Dub and pretty simple setup, that links in 3 C/C++ static

The first I don't understand as it should be in some run-time
libraries. The second indicates a problem with debug / non-debug
runtime libraries. However, I would expect that the correct run-time
libraries are used.
I'm building my code with just: dub build --arch=x86_64
Any idea?
By the looks of it, the C(++) libs have been compiled with /MDd (debug
DLL version of MSVC runtime libs),
Hi, that's correct.
while DMD and LDC default to the static (release) libs, i.e., /MT.
Interesting... this little but important detail is not very well
document. The only reference I found is [1] but nothing in the official
compiler documentation page.
The according switch for DMD/LDC is `-mscrtlib` IIRC.
Yes, it is. Seems there is no difference between multi-threaded and
non-multi-threaded.
Thanks, that worked.
