Issue ID: 22805
Summary: [Reg 2.099] missing libraries when using some windows
API calls with -m32
Product: D
Version: D2
Hardware: x86
OS: Windows
Status: NEW
Severity: regression
Priority: P1
Component: dmd
Assignee: [email protected]
Reporter: [email protected]
Not a big issue, but compiling and linking this file:
module win;
import core.sys.windows.windows;
void main()
{
MessageBoxA(null, "hi", "there", MB_OK);
}
with
> dmd -m32 win.d
used to work, but after the change to COFF by default, it produces
win.obj : error LNK2019: unresolved external symbol _MessageBoxA@16 referenced
in function __Dmain
win.exe : fatal error LNK1120: 1 unresolved externals
This is caused by not specifiying the library user32.lib on the command line.
In contrast, invoking optlink automatically adds it (and kernel32.lib).
Maybe the same should be done for COFF to avoid breaking existing build
scripts.
