On Linux:

foo.d:
import std.stdio;
void main() { writeln(import("dir/bar.txt")); }

dmd -J. foo.d # ok

On Windows:

Error: file "dir/bar.txt" cannot be found or not in a path specified with -J

I tried the obvious buildPath("dir", "bar.txt") instead and now:

Error: file "dir\\bar.d" cannot be found or not in a path specified with -J

I tried r"dir\bar.txt" and "dir\\bar.txt" and still nothing. What am I supposed to do? Thanks,

I have encountered this as well, don't know if it's a bug or intended. My workaround is to pass -Jdir

There is already a bug report for this problem:

https://issues.dlang.org/show_bug.cgi?id=14349

Also the manual is not clear about the feature: should a -J path be recursive or not ?
