Error compiling go programme

[sidahmedabdelillah]

Hello. I am working demonstration for ebpf.

This is the go programme

package main

import "C"

import (
	"fmt"
	"os"
	"unsafe"

	bpf "github.com/aquasecurity/libbpfgo"
)

type Target struct {
	Pid  uint32
	Comm [16]byte
	Path [256]byte
}

func main() {
	bpfModule, err := bpf.NewModuleFromFile("ebpf.o")
	if err != nil {
		panic(err)
	}
	defer bpfModule.Close()
	if err := bpfModule.BPFLoadObject(); err != nil {
		panic(err)
	}
	targetMap, err := bpfModule.GetMap("target")
	if err != nil {
		fmt.Fprintln(os.Stderr, err)
		os.Exit(-1)
	}

	// update the map

	key := uint32(0x1337)
	var val Target
	copy(val.Comm[:], "procname")
	copy(val.Path[:], "/home/azureuser/ebpf/secret")
	val.Pid = uint32(9999)
	keyUnsafe := unsafe.Pointer(&key)
	valueUnsafe := unsafe.Pointer(&val)
	targetMap.Update(keyUnsafe, valueUnsafe)
}

I compiled the bpf using this commande

clang -g -O2 -c -target bpf -o ebpf.o ebpf.c

and tried building the go using this
CC=gcc CGO_CFLAGS="-I /usr/include/bpf" CGO_LDFLAGS="/usr/lib64/libbpf.a" sudo go build -o libbpfgo-prog
I got the error
../../../go/pkg/mod/github.com/aquasecurity/libbpfgo@v0.6.0-libbpf-1.3/map-common.go:51:39: could not determine kind of name for C.BPF_MAP_TYPE_BLOOM_FILTER

CGO_CFLAGS="-I /usr/include/bpf"

It seems you're using the installed libbpf include and not the one provided by libbpfgo. I guess your system libbpf version hasn't support to BPF_MAP_TYPE_BLOOM_FILTER (introduced by libbpf/libbpf@168cf9b).

Take a look at libbpfgo selftest building process for more information:

libbpfgo/selftest/common/Makefile

Lines 17 to 18 in 90dbfff

	CGO_CFLAGS_STATIC = "-I$(abspath $(OUTPUT)) -I$(abspath ../common)"
	CGO_LDFLAGS_STATIC = "-lelf -lz $(LIBBPF_OBJ)"

Closing as it doesn't seem a problem. Please reopen it if relevant.
