Build DeepMind Lab Failed? about lab HOT 5 CLOSED

@xjwxjw sudo apt-get install realpath

from lab.

Adding the "export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libz.so" to ./bashrc file.It finally works.

yeah, thanks.It works.
But then I try to build it like this:"bazel run :random_agent --define headless=false". It fails, and get the following output:

INFO: Running command line: bazel-bin/random_agent '--length=10000' '--width=640' '--height=480'

Do you have any idea with it?Much Thanks!

I try the command :"bazel run :random_agent --define headless=false -- --length=10000 --width=640 --height=480". It is the same output as "bazel run :random_agent --define headless=false".

@xjwxjw: Thanks for investigating, and @jithinoc for the pull request. You shouldn't have to preload libz, since we compile it from source and link it statically. If there is a loading error, could you try adding the "undefined symbols" to dmlab.lds first? (For an easy hack, just replace the "visible" section in dmlab.lds by *' and see if that resolves it, and then narrow it down to the symbols that are actually used.)
