libgcc_s.so.1 must be installed for pthread_cancel to work

[Heavy02011]

running into this error under ubuntu 18.04 after

python example.py

Any ideas how to fix this?

log output

[crizCraig]

Thanks @Heavy02011 - Haven't seen this before, but perhaps try

sudo apt-get install build-essential

[Heavy02011]

Checked that, it's already installed

[Heavy02011]

any test routines availabe to check the whole system?

[crizCraig]

Hmm, install.py attempts to do that - but I've not seen this so I think our resident Unreal toolchain expert may have some advice here... @adamrehn any thoughts?

[Heavy02011]

that's the install log

[adamrehn]

This error is new to me. That file ships with Ubuntu (located at /lib/x86_64-linux-gnu/libgcc_s.so.1), so it should always be present, irrespective of the packages that are installed.

[Heavy02011]

the lib is there

(dd) rainer@neuron:/lib/x86_64-linux-gnu$ ll libgcc*
-rw-r--r-- 1 root root 96616 Mai  8  2019 libgcc_s.so.1

and many more copies
maybe that could cause the problem...

[Heavy02011]

any new ideas to solve it?

[crizCraig]

@Heavy02011 - Did you install under Miniconda? If not, you could try that?

Also, if you wouldn't mind, can you try running

/home/rainer/Deepdrive/deepdrive-sim-linux-3.1.20191114055550/DeepDrive/Binaries/Linux/DeepDrive

And see if the sim runs without the Python bindings connecting?

So it's in the Miniconda env. You could likely add it to LD_LIBRARY_PATH and get past this particular error, but I think Miniconda is going to be best bet to get things working for you.

[Heavy02011]

thx Craig, will test that!

[vasica38]

@Heavy02011 did you work out ?

[Heavy02011]

Sorry for the long response, tried again still the same when doing

(dd) rainer@neuron:~/Deepdrive/deepdrive-sim-linux-3.1.20200229010300/DeepDrive/Binaries/Linux$ ./DeepDrive

I get

Any chance to run it in docker?
