Bazel no longer dispatches to a helper script to run the compiler; instead Bazel now has a CROSSTOOL definition for Visual C++ and drives the compiler directly. bazel build --compiler=gcc-5 // # Build Bazel Setup. Libraries are not in Today, we're excited to share a preview of Bazel Code Search, a major upgrade to Bazel's code search site. Thanks to Jim To enable LSan on your builds including Abseil code (using Bazel):. Because that is nontrivial endeavor, Bazel tries to autodetect your toolchain using cc_configure. If you prefer to build from sources using Ubuntu 14. To fix, follow the instructions in Bazel wiki: 18 Sep 2017 in apple_cc_toolchain rule @local_config_cc//:cc-compiler-darwin_x86_64: Xcode version must be specified to use an Apple CROSSTOOL. I much prefer to install Tensorflow using Anaconda Python and you can find a tutorial for that here. Installing and keeping LLVM up to date; Troubleshooting bazel/clang/llvm errors. These configs are required to configure Bazel to issue commands that will execute inside a Docker container via a remote execution environment. # Note that LSan requires Clang instead of gcc.
