https://issues.dlang.org/show_bug.cgi?id=23072 Issue ID: 23072 Summary: Creating a shared library using VS 2019 cannot find `open` Product: D Version: D2 Hardware: All OS: Windows Status: NEW Severity: major Priority: P1 Component: dmd Assignee: nobody puremagic.com Reporter: alphaglosined gmail.com Simple scenario: ```d module testshared.d import std.stdio; void f() { writeln("Hello, World!"); } ``` $ dmd -shared testshared.d This produces a lot of linker errors due to missing libcmt.lib. With that added only one linker error remains: phobos64.lib(gzlib.obj) : error LNK2019: unresolved external symbol open referenced in function gz_open This works with ldc 1.29.0-beta1, but not dmd 2.099.0. I managed to copy some arguments from ldc that got it to link. $ dmd -shared testshared.d -L/DEFAULTLIB:msvcrt -L/DEFAULTLIB:vcruntime oldnames.lib That command worked. --
