Object.d seems to be a special case in many ways.
When building minlibd I was not able to have an empty or my

I do not remember any more what all the problems were.
Object.d (or .di) is always imported even if it is not
mentioned. In this case gdc may find another object.d from
the standard library. Current directory is not searched
unless you put -I. to the command line. There may now be two
conflicting files.
Actually, the situation may also be the opposite:
object.d is found in the current directory and imported twice,
but the current directory is not in the include search path
and so the file is not accepted as a valid library file.
Thanks Timo,
You're right: object.d and/or object.di are imported
automatically from the current directory with or without the
-I. option. Therefore, removing object.d from my compile line
got rid of the duplicate messages, but one instance still
remains.
Here's my new compile line:
arm-none-eabi-gdc -I. -march=armv7e-m -mcpu=cortex-m4
-mtune=cortex-m4 -mthumb -fno-emit-moduleinfo -c
-ffunction-sections -fno-exceptions -fdata-sections start.d
notice I've removed object.d, but the file still exists in the
same folder as start.d
I tried:
1) adding the -I. to the compile line to make my object.d
*official*
2) moving my object.d to my default include folder
3) renaming object.d to object.di and repeating 1. and 2.
4) renaming object.d to object_.d and repeating 1. and 2.
All of these still produce the same error messages. The
interesting thing is I was able to compile my code with my
build from the *official* GDC 4.8 branch; but Johannes's
arm-old backport gives me the object.d errors. So, something
must have changed since the 4.8 branch.
If object.d is special, please let me know how its handled. Is
this actually a question for the DMD folks?
Thanks,
Mike
I should probably add that if I remove my object.d file from the
file system, I get:
cc1d: error: cannot find source code for runtime library file
'object.d'
cc1d: note: dmd might not be correctly installed. Run 'dmd -man'
for installation instructions.
I compiled gdc with the without the default phobos/runtime
library, so my default include and lib folders are empty.
object.d: Can't compile with it; can't compile without it.
