The gcc-gdc package (currently in version 11.5.0) [1] lacks the *.d files of the standard library (libphobos, including druntime).
How to reproduce: ============ hello.d ============ import std.stdio; void main () { writeln("Hello world!"); } ================================= $ gdc hello.d Expected: Success, and creates a file a.exe. Actual: d21: error: cannot find source code for runtime library file 'object.d' d21: note: dmd might not be correctly installed. Run 'dmd -man' for installation instructions. d21: note: config file: not found The expected location of the runtime library file 'object.d' is in /usr/lib/gcc/x86_64-pc-cygwin/11/include/d/object.d but the entire directory /usr/lib/gcc/x86_64-pc-cygwin/11/include/d is missing.
