bpftool: error while loading shared libraries: libLLVM-17.so: cannot open shared object file: No such file or directory #132

Closed NobinPegasus closed 6 months ago

NobinPegasus commented 7 months ago

When I try to invoke the bpftool it shows the following error. bpftool: error while loading shared libraries: libLLVM-17.so: cannot open shared object file: No such file or directory

And when I try to compile the bpftool I get the following error:

Hi, this seems to be an issue with libbpf's compilation. Do you have libelf installed (for example, package libelf-dev on Ubuntu)? What's the output of make V=1?

NobinPegasus commented 7 months ago

@qmonnet Yes I've libelf-dev installed. Output of make V=1:

I've tried to reproduce in an Ubuntu 23.04 container, but it compiled just fine for me.

What are your gcc and libelf-dev versions? (gcc --version, apt-cache policy libelf-dev, I get 12.3.0 and 0.188-2.1, respectively).

I suppose you get the same error if you try to compile libbpf on its own?

Running CFLAGS=-H make I see that I've got the libelf headers pulled during compilation, is this the case for you as well?

Your sudo make doesn't seem to build anything, it looks like the library was built already - please try make clean before, or make -B to force-rebuild.

It's weird if libbpf builds on its own but not with bpftool, the commands should be the same. Could you compare the output of make -B V=1 in bpftool, and make -B V=1 in libbpf, regarding usdt.o? In my case I get the same thing (only with absolute vs. relative paths):

qmonnet:~/bpftool/src$ make -B V=1
...
cc -I. -I../include -I../include/uapi -g -O2 -Werror -Wall -std=gnu89 -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Wno-unknown-warning-option -Wno-format-overflow   -c usdt.c -o /home/qmonnet/bpftool/src/libbpf/staticobjs/usdt.o

...

Any particular reason why you build with sudo?

I'm sorry, I still don't know where the issue comes from.

If you want to try to debug this further, you can try to run make -H again (making sure to rebuild the objects, e.g. make -B -H, or directly cc -H -I. -I../include -I../include/uapi -g -O2 -Werror -Wall -std=gnu89 -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/local/include/libelf -I/usr/local/include -c usdt.c -o staticobjs/usdt.o, and look for the included files. For reference, I get the list below.

Another possibility would be to grep your /usr and search for a file where GElf_Shdr, but not GElf_Nhdr, would be defined (both are typdef-ed in /usr/include/gelf.h only for me).

If instead you want more people to look into it, I'd recommend taking the issue to the libbpf repo or better yet, the BPF mailing list.

Reading again your initial description, when you mention the error bpftool: error while loading shared libraries: libLLVM-17.so: cannot open shared object file: No such file or directory, what binary does this refer to? The one you tried to compile, or is it a binary you installed in another way?

@qmonnet When I cc I get this.

I solved the issue. It was an issue with libelf. I downloaded a latest libelf version. Then Configured and installed it. libelf also had some dependency missing like specific versions of sqlite, libcurl, libarchive

qmonnet commented 6 months ago

Great to hear you solved it, thanks for reporting back! For future reference, could you please indicate what was the libelf version that caused the issue, and what version number fixed it?

NobinPegasus commented 6 months ago

For me 0.188-2.1 caused the error. And It's the version of libelf-dev. But what I then did was build elfutils-0.191 manually which solved the error. Don't exactly know if the issue is from version 0.188-2.1 or something else caused it. Because still now when I dpkg-query -s libelf-dev I find the version is 0.188-2.1

qmonnet commented 6 months ago

OK, thank you!

bfxyzshb commented 3 months ago

you need install libelf from source libelf source: https://github.com/arachsys/libelf
