Hi, Im using GDC 4.9.0 compiler. I have template classes like "public class LinkedList(T) {...}" and when I try compile it together, everything works fine. But when I compile every source file to separate object file and link it together with ld Ill get errors like:

"/os/KernelLand/Kernel/TaskManager/Thread.d:99: undefined reference to `_D7Library10LinkedList45__T10LinkedListTC11TaskManager6Thread6ThreadZ10LinkedList6__ctorMFNaNbNfZC7Library10LinkedList45__T10LinkedListTC11TaskManager6Thread6ThreadZ10LinkedList'"

Im compiling it with command like:
gdc -mcmodel=kernel -nostdlib -mno-red-zone -Wall -masm=intel -frelease -finline-functions -O3 -o obj-x86_64/abc.d.o -c abc.d

Here is

LinkedList class https://github.com/Bloodmanovski/Trinix/blob/dc80f3197f59fe96e9f4e29cea670ff2c7eaa342/KernelLand/Kernel/Library/LinkedList.d


Can anyone help me how to solve this problem? Thanks
(Sorry for bad english)

Could anyone help me please?

Try linking with gdc instead of ld.

Sounds like you're not passing in LinkedList.d while compiling a file that uses it. You need to include all used files, including imports, on the command line when compiling. The undefined reference indicates it can't find the source code or di file containing LinkedList. Tools like rdmd do this for you by looking at the imports used automatically.

If not that, I'm not sure if this will help, but try using -femit-templates (similar to -allinst in DMD I believe?).

Besides that, all I can really suggest is double checking that you're actually including the object file containing LinkedList when you're linking and the source file when compiling.

I have defined LinkedList as di file, Im not compiling it. Im compiling every .d file separately, eg. main.d -> main.d.o without including anything else.

I tried to use -femit-templates but nothing happnes.

I dont have object file of LinkedList.di, Im only importing it in source file and with -I
