No such file:dmlab.lds Error!

[cumttang]

When I run the installation of deepmind lab on Ubuntu16.04, all dependencies have been installed, but there still some errors:

ERROR: /home/tommy/IMPALA/lab/BUILD:895:1: Linking of rule '//:libdmlab_headless_hw.so' failed (Exit 1)
gcc: error: :dmlab.lds: No such file or directory
Target //python/pip_package:build_pip_package failed to build

INFO: Elapsed time: 125.820s, Critical Path: 72.23s
INFO: 835 processes: 835 linux-sandbox.
FAILED: Build did NOT complete successfully

How to fix it, please?

[tkoeppe]

Can you provide the Bazel invocation that caused this error?

[cumttang]

$ cd lab
--Build the Python interface to DeepMind Lab
lab$ bazel build -c opt //:deepmind_lab.so

When I ran the last bold line, finally, the error took place:(

I have same issue with Dockerfile from scalable_agent project

I solved the issue while working with gh://deepmind/scalable_agent project. It's because of bazel 0.17.1 that was released 5 days ago. (2018-09-14)

The problem is that the following dockerfile code line,

RUN echo "deb [arch=amd64] http://storage.googleapis.com/bazel-apt stable jdk1.8"

gets the latest stable version which is bazel 0.17.1.

for the deepmind/scalable_agent issue #16
I changed the line

RUN echo "deb [arch=amd64] http://storage.googleapis.com/bazel-apt stable jdk1.8" | \
    tee /etc/apt/sources.list.d/bazel.list && \
    curl https://bazel.build/bazel-release.pub.gpg | \
    apt-key add - && \
    apt-get update && apt-get install -y bazel

to

RUN export BAZEL_VERSION=0.16.1 && \
    wget https://github.com/bazelbuild/bazel/releases/download/$BAZEL_VERSION/bazel-$BAZEL_VERSION-installer-linux-x86_64.sh && \
    sed -i 's@sudo@, @g' bazel-$BAZEL_VERSION-installer-linux-x86_64.sh && \
    chmod +x bazel-$BAZEL_VERSION-installer-linux-x86_64.sh &&\
    ./bazel-$BAZEL_VERSION-installer-linux-x86_64.sh --user

ENV PATH="/root/bin:${PATH}"

And It should build without errors. (as of 2018-09-18)

You can use the Dockerfile here

Unlucky, https://github.com/bazelbuild/bazel/releases/download/$BAZEL_VERSION/bazel-$BAZEL_VERSION-installer-linux-x86_64.sh is not available now:(

[bboyseiok]

It's meant to be used inside dockerfile (that's why export BAZEL_VERSION=0.16.1 exists.)

Try with this then :)

Thanks a lot for reporting this! There has been a change in Bazel semantics. It was actually fixed internally a while ago, but I missed that and forgot to release that change. Fixed in 8ca0776.
