I'm trying to build and use the D frontend for GCC.  I've gotten it to (seemingly) compile, but I'm getting an odd problem when trying to use it.  I made a basic test file, test.d, which is literally just "void main() {  }". When I do "gdc -c test.d" I get this:

read error, errno = 2
Error: Error reading file 'test.d'

Could this be one of the intrnal compiler errors that the "Grey Areas/Known Issues" section of http://home.earthlink.net/~dvdfrdmn/d/ refers to?  Also, If I try "gdc test.d" without the "-c" I get "gdc: libphobos.spec: No such file or directory". The whole problem couldn't be because I haven't built phobos could it?  I don't think I would be able to build phobos anyway without the D frontend working, since isn't part of phobos written in D?

Try to give the whole path of "test.d" to the compiler. I haven´t done much in D yet, but i had that problem too (same error message), because i only gave "hello.d" to it, which was not in the same directory as the compiler.
The error should rather be "couldn´t find 'hello.d'" or such, since this message is a bit confusing.

Hmm, no it still gives me that message.

I just converted the source file from using DOS-style line breaks to Unix-style (I'm on Cygwin, btw.  I wanted to be able to use DOS-style breaks, but oh well...) and now instead of getting:

read error, errno = 2
Error: Error reading file 'test.d'

Instead of that, I'm now getting:

Error: Error reading file 'object.d'

Even though I never made any reference to such a file.

What platform are you using? Where are you installing gdc? Not finding libphobos.spec sounds like an install issue. Maybe also try passing the -v flag to get verbose output.

I'm not sure if anyone has tried gdc on cygwin. You might be in uncharted waters here.

object.d is read implicitly. It is in dmd/src/phobos/object.d

Is there an environment variable where that path is supposed to be set?

Is that where it's supposed to be in the D frontend for GCC?

My "object.d" is in "$(gcc-dir)/include/d/" along with a lot of other phobos-files...
