build bpfd failed

[realmz]

I followed the steps in INSTALL document to build bpfd on ubuntu 16.04 host

[ 80%] Building C object CMakeFiles/bpfd.dir/src/remote_perf_reader.c.o
/home/stemia01/temp/bpfd/src/remote_perf_reader.c: In function ‘remote_raw_reader_cb’:

printf("raw_cb: b64 encode failed for reader fd=%d\n", reader->fd);

}

It seems missing struct perf_reader definition in bcc-deps/perf_reader.h?

Could you let me know your usecase for bpfd?

Hi Joel,

I'm interested in epbf, and want to try this powerful tool on hikey960 board. Now It can pass the build after tweak the ‘struct perf_reader’.

[joelagnel]

Since hikey runs Android, please check out the androdeb project. It is more suitable than bpfd for running bcc on Android.

Thanks Joel, androdeb chroot run debian is very cool, just several commands to run BCC on android file system. And bpfd can work as well.

[joelagnel]

Yes. And patches to androdeb are welcome ofcourse!
