This rule is missing dependency declarations for the following files

[lf94]

Hello,

I'm trying to compile TensorFlow on FreeBSD. So far things have been going OK. Someone has made a Bazel 0.2.2b port that works, but I am getting errors that have been discussed before on this issue tracker.

Apologies if this has already been fixed, but I have tried everything out there besides latest Bazel. There are no search results that indicate this is a solved problem.

Things I have tried:

• Added cxx_builtin_include line to tools/cpp/CROSSTOOL
• Created a symlink between /usr/local/lib/gcc48 and /usr/lib/gcc
• Used Clang (which bypasses this problem but fails the build because it doesn't support a GCCism...)

Here is the error:

[lee@ ~/3rdparty/tensorflow]$ bazel build --genrule_strategy=standalone --spawn_strategy=standalone -c opt //tensorflow/tools/pip_package:build_pip_package;
INFO: Found 1 target...

tools/cpp/CROSSTOOL isn't actually getting sued; the one generated from tools/cpp/CROSSTOOL.tpl by tools/cpp/cc_configure.bzl is being used instead. Try adding your paths there.

@damienmg might be able to help on actually solving the problem.

[damienmg]

Can you give me the output of echo | gcc -E -xc++ - -v?

Also what is the content of the bazel-tensorflow/external/local_config_cc/CROSSTOOL file?

[lf94]

I wanted to mention that after some quick investigation, the port overwrites my changes to the CROSSTOOL file. I will try modifying tools/cpp/cc_configure.bzl and report back.

In the mean time, Clang 3.8 with Bazel works perfectly and I can compile TensorFlow (although there is still an issue I'm having but that's off-topic).

On FreeBSD it copies tools/cpp/CROSSTOOL.

Ok so here the instruction:
add to tools/cpp/CROSSTOOL:

    cxx_builtin_include_directory: "/usr/local/lib/gcc48/include/c++/"
    cxx_builtin_include_directory: "/usr/local/lib/gcc48/include/c++/x86_64-portbld-freebsd10.1"

    cxx_builtin_include_directory: "/usr/local/lib/gcc48/gcc/x86_64-portbld-freebsd10.1/4.8.5/include-fixed"

Recompile Bazel and use that new binary in tensorflow (but do bazel clean --expunge in tensorflow first).

Assigning to @aehlig for further reference for his effort to make Bazel works on FreeBSD.

[aehlig]

I believe this issue is fixed by now, given that science/py-tensorflow is in the ports collection now.

/cc @amutu FYI.
