about the header file error #2

Open qwe75983 opened 2 years ago

qwe75983 commented 2 years ago

When I finished configuring the environment I found some errors as follows

root@zy-virtual-machine:~/桌面/ebpf-http-parser-master# make
go generate
/root/桌面/ebpf-http-parser-master/kprobe.c:3:10: fatal error: 'bpf_tracing.h' file not found
#include <bpf_tracing.h>
         ^~~~~~~~~~~~~~~
1 error generated.
Error: clang-9: exit status 1
exit status 1
main.go:30: running "go": exit status 1
make: *** [Makefile:8：main] 错误 1

So I tried to find the header file, and I put the header file of the bpftool folder in it, and then I found that something else was missing

root@zy-virtual-machine:~/桌面/ebpf-http-parser-master# find / -name bpf_tracing.h

I put /usr/src/linux-hwe-5.13-headers-5.13.0-52/arch/x86/include/asm/trace/common.h and found other unsolvable problems

Hi. I guess that you cloned this repository without --recursive.

ebpf-http-parser uses github.com/cilium/ebpf/examples/headers and linked at here, so you should clone git submodule. Try it.

git submodule update --init --recursive

Thanks.
