Issue ID: 22630
Summary: It is possible for VS to be installed and providing VC
directory without VC libraries being installed
Product: D
Version: D2
Hardware: x86_64
OS: Windows
Status: NEW
Severity: critical
Priority: P1
Component: druntime
Assignee: [email protected]
Reporter: [email protected]
As of:
VS 2022
dmd 2.098.1 but may also effect going back to 2.091 as per issues 22525 and
21867.
Known environment to cause this:
For VS install with just F#.
During installer of dmd select MinGW.
During linking it is known that:
/LIBPATH:"C:\Program Files\Microsoft Visual Studio\2022\Community\VC\lib\amd64"
will be added.
It will error with:
lld-link: error: could not open 'libcmt.lib': no such file or directory
Directory that does exist:
C:\Program Files\Microsoft Visual Studio\2022\Community\VC
But not:
C:\Program Files\Microsoft Visual Studio\2022\Community\VC\lib
This may be fixable by changing getVCLibDir to check before returning that the
path returned actually exists and not just return whatever it thinks should be
the location.
