Support for gcc

Hello, I use gcc 12.1.0 to compile a source file:
t.c
struct t {
  int a:2;
  int b:3;
  int c:2;
} g;
with gcc -c -gbtf t.c
and try to use libbpf API btf__parse_split, bpf_object__open, and
bpf_object__open to parse and load into the kernel, but it failed with
"libbpf: elf: /path/to/t.o is not a valid eBPF object file".

Is it wrong for me to do so? Due to some constraint, I cannot use
clang but gcc. How to parse and load gcc compiled object file with
libbpf?
