Hey. In my kernel I wanted to use some header files from C++, for example vector. C++ compiles, but the ld linker throws an error. Compile a kernel so: Code: nasm -f elf32 ./source/kernel.asm -o kasm.o g++ -m32 -std=c++11 -c ./source/kernel.cpp -o kc.o ld -m elf_i386 -T link.ld -o kernel-0 kasm.o kc.o Please help. |

You can't, remember this is your OS, there are no standard libraries, nothing. You have to write it yourself or port a third party one, I prefer the former.

If you want to use something like vector in a kernel you need to: 1. Implement paging 2. Build an allocator against your paging 3. Tie that in as a custom allocator against vector or implement your own vector class |
