I don't understand what i need for static init

[shadow rock]

I am trying to get static initialization to work but with little to no success
I've built my toolchain according to https://wiki.osdev.org/GCC_Cross-Compiler but i've swapped the target for x86_64-none-elf

I have the following cmake build file ```cmake
project (kernel CXX ASM)

add_executable(kernel
kmain.cpp
memory.hpp
)

target_compile_options(kernel PRIVATE "-ffreestanding"
"-Wall" "-Wextra" "-fno-exceptions" "-fno-rtti")

target_link_options(kernel PRIVATE "-ffreestanding" "-nostdlib" "-nostartfiles" "-nodefaultlibs" -T ${CMAKE_SOURCE_DIR}/toolchain/linker.ld)

target_include_directories(kernel PRIVATE ${limine_INCLUDE_DIR})
target_link_libraries(kernel)

install(TARGETS kernel DESTINATION ${ISO_SYSROOT}/boot)

the issue is i get the following linking error /opt/gcc-x86_64-elf/bin/x86_64-none-elf-g++ --sysroot=/opt/gcc-x86_64-elf -ffreestanding -nostdlib -nostartfiles -nodefaultlibs -T /home/iulian/dev/BadOS/toolchain/linker.ld CMakeFiles/kernel.dir/kmain.cpp.obj -o kernel CMakeFiles/kernel.dir/kmain.cpp.obj: in function `_Z41__static_initialization_and_destruction_0v': kmain.cpp:(.text+0xc0): relocation truncated to fit: R_X86_64_32 against `.bss' /opt/cross/x86_64-none-elf/bin/ld: kmain.cpp:(.text+0xca): undefined reference to `__dso_handle' kmain.cpp:(.text+0xcf): relocation truncated to fit: R_X86_64_32 against `.bss' kmain.cpp:(.text+0xd4): relocation truncated to fit: R_X86_64_32 against symbol `_ZN5helloD1Ev' defined in .text._ZN5helloD2Ev[_ZN5helloD5Ev] section in CMakeFiles/kernel.dir/kmain.cpp.obj /opt/cross/x86_64-none-elf/bin/ld: kmain.cpp:(.text+0xd9): undefined reference to `__cxa_atexit' /opt/cross/x86_64-none-elf/bin/ld: kernel: hidden symbol `__dso_handle' isn't defined /opt/cross/x86_64-none-elf/bin/ld: final link failed: bad value collect2: error: ld returned 1 exit status make[2]: *** [kernel/CMakeFiles/kernel.dir/build.make:100: kernel/kernel] Error 1 make[2]: Leaving directory '/home/iulian/dev/BadOS/build' make[1]: *** [CMakeFiles/Makefile2:174: kernel/CMakeFiles/kernel.dir/all] Error 2 make[1]: Leaving directory '/home/iulian/dev/BadOS/build' make: *** [Makefile:136: all] Error 2

passing both crtbegin and crtend manually with the _init and _fini function defined as ```c
attribute((used, section(".init")))
extern "C" void _init()
{

}

attribute((used, section(".fini")))
extern "C" void _fini()
{

}``` still fails

i have no idea what's wrong even the smalles of guidance would help
