It has to do with module references to druntime stuff. You
can either try adding a
pragma(LDC_no_module_info); //I think it is spelled correctly.
or you can use ldc to link and it will link druntime
gcc ccode.c -c
ldc2 dcode.d code.o
I don't know how well that will work.
Many thanks, I tried:
```
pragma(LDC_no_moduleinfo) //
https://wiki.dlang.org/LDC-specific_language_changes#LDC_no_moduleinfo
```
which worked, your method of doing the final compilation using
ldc2 (or dmd) also works :-)
Is there a dmd equivalent for `pragma(LDC_no_module_info);`?
Attempting the final compilation `gcc -o output ccode.o
dcode.o` after the second stage compilation `dmd -c dcode.d`
gives an error:
```

Those functions are the bounds checking function, the non
unittest assert function, the unittest function an module
initialisation function respectively. dmd -boundscheck=off
-release should get rid of the first two, you didn't compile
with -unittest so I'm not sure why the thord one is there at
all. For _d_dso_registry all i can suggest is see what -betterC
gets you.
I just compiled `dmd -c dcode.d -betterC -boundscheck=off`
(-betterC probably makes -boundscheck=off irrelevant but I threw
it in as a prayer) I am still getting:
```
dcode.o:(.text.d_dso_init[.data.d_dso_rec]+0x22): undefined
