Undefined reference to symbol 'ceil@@GLIBC_2.2.5' at build time

[drgriffis]

I'm working on compiling Tensorflow from source, using non-standard GCC/etc. installations. Environment info: RHEL 6.7, GCC 5.2.1, Bazel 0.1.5. I'm installing Tensorflow from HEAD (commit f82ad36). I'm using a non-CUDA configuration. I've followed the steps @sethbruder suggests in his comment on bazel#649, including copying the contents of tools from bazel into tensorflow/tools/ and into tensorflow/google/protobuf/tools/. This is possibly related to #332, as I'm getting the same error, but at build time as opposed to API usage.

I've tried to set up the relevant paths for my non-standard system resource install using the following settings before invoking bazel:

export LDFLAGS="-Wl,-rpath,/opt/rh/devtoolset-4/root/usr/lib64 -lrt -lm"
export CC="/opt/rh/devtoolset-4/root/usr/bin/gcc"
export CXX="/opt/rh/devtoolset-4/root/usr/bin/g++"
export JAVA_HOME="/u/drspeech/opt/jdks/jdk1.8.0_25"
export LD_LIBRARY_PATH="/opt/rh/devtoolset-4/root/usr/lib:${LD_LIBRARY_PATH}"
export BAZEL_ARGS="--verbose_failures"
export EXTRA_BAZEL_ARGS="${EXTRA_BAZEL_ARGS} --linkopt=-Wl,-rpath,/opt/rh/devtoolset-4/root/usr/lib64"
export EXTRA_BAZEL_ARGS="${EXTRA_BAZEL_ARGS} --linkopt=-Wl,-rpath,/u/drspeech/opt/jdks/jdk1.8.0_25/lib"
export EXTRA_BAZEL_ARGS="${EXTRA_BAZEL_ARGS} --linkopt=-lz"
#export EXTRA_BAZEL_ARGS="${BAZEL_ARGS} --linkopt=-Wl,-rpath,/usr/local/cuda-7.0/lib64"
export PYTHON_MAJOR_VERSION=3
export PYTHON_BINARY=/u/drspeech/opt/python-3.5.1/bin/python3
export MYBAZEL=/u/drspeech/opt/bazel-0.1.5/0.1.5/bazel-0.1.5/output/bazel

(there may be some leftover settings; this is adapted from what I used for building bazel in bazel#925)

When I invoke bazel with

${MYBAZEL} build -c opt //tensorflow/tools/pip_package:build_pip_package

I get the following error output:

It seems like I may be missing an "-lm" flag in the invocation to gcc to the protobuf target; I've tried including it in LDFLAGS as shown above, but it doesn't seem to be appearing in the gcc invocation.

(You may get more help again from the bazel team on this one ...)

undefined reference to symbol 'ceil@@GLIBC_2.2.5'
I get the same and a great many Info/Warnings.
this issue was patched and merged, but I simply follow the syntaxnet instructions:

git clone --recursive https://github.com/tensorflow/models.git
cd models/syntaxnet/tensorflow
./configure
cd ..
bazel test syntaxnet/... util/utf8/...

it still gives:

is this a Bazel issue? that's a fairly obscure build system, what should I do?

[rasmi]

@sammoes did you figure this out?

EDIT:
This did the trick for me. Modify LINK_OPTS in bazel-tensorflow/external/protobuf/BUILD by adding the -lm flag to //conditions:default:

LINK_OPTS = select({
    ":android": [],
    "//conditions:default": ["-lpthread", "-lm"],
})

Thanks @rasmi . Just to add that the file that I needed to edit to fix my problem was here:
/home/my_user_name/.cache/bazel/_bazel_my_user_name/e2c708629a3b2c9645109cfe38374186/external/protobuf/BUILD

[Mchapuis]

Code from @rasmi and help from @czakon worked! :D

Code from @rasmi and help from @czakon worked for me too. Thanks, Will
