Undefined references to C++ standard library symbols about clusterfuzzlite HOT 13 CLOSED

Apt should be fine in most cases. I'm not sure what's going on here. Let me take a look.

from clusterfuzzlite.

Hmmm...I wasn't able to reproduce this after running CFLite locally on your repo. See the logs. Did you fix the issue?

This was the command I used to run CFLite locally btw:
docker run -it -v /var/run/docker.sock:/var/run/docker.sock -e PROJECT_SRC_PATH=/tmp/workspace/cflite-example -e BUILD_INTEGRATION_PATH=.clusterfuzzlite -e REPOSITORY=cflite-example -e FILESTORE=no_filestore -e WORKSPACE=/tmp/workspace -e CFL_PLATFORM=standalone -v /tmp/workspace:/tmp/workspace --entrypoint python3 gcr.io/oss-fuzz-base/clusterfuzzlite-run-fuzzers:v1 /opt/oss-fuzz/infra/cifuzz/cifuzz_combined_entrypoint.py

You need to copy cflite-example into /tmp/workspace/cflite-example for this to work.

from clusterfuzzlite.

No, I did not fix it. And I tried your command to run locally, it gives me the same linker errors I posted initially. Are you on cflite-example's linker-errors branch and not on main?

from clusterfuzzlite.

Oh sorry I was on main. Lemme try again.

from clusterfuzzlite.

You mean link-boost branch right?

from clusterfuzzlite.

Yes.

from clusterfuzzlite.

Any news on this? Were you able to reproduce the issue?

from clusterfuzzlite.

I'll probably have to take a look at this next week. But I can try now.

from clusterfuzzlite.

I was able to reproduce this.
I'm not a boost expert, but maybe there's something about boost that makes it required to build from source to use in ClusterFuzzLite?
In oss-fuzz it seems like most boost users do this:

This comment is especially revealing I think boost needs to be built from source to use with libc++, the apt versions must use libstdc++

I would ask this question in oss-fuzz btw, the build setup is the same and are many helpful oss-fuzz users some of whom might be more familiar with this problem than me.

from clusterfuzzlite.

to be clear though, I think boost is an exception. I feel like many libraries can be installed via apt. I would guess most are in oss-fuzz

from clusterfuzzlite.

Ok thanks I'll try that.

from clusterfuzzlite.

Unsurprisingly this worked, thanks. So basically if you have problems getting a dependency to work, check how users of OSS-Fuzz do it. Could be useful mentioning in the ClusterFuzzLite docs.
