Question

我正在尝试使用此命令在OSX上使用bazel构建一个tensorflow工具：

bazel build tensorflow/python/tools:freeze_graph

输出gcc -v：

gcc版本4.9.4（MacPorts gcc49 4.9.4_1）

bazel version

0.11.1

Xcode版本：

Xcode 9.2

但是，我收到错误：

如何正确编译？

看起来你在某处设置了CC环境变量？ Bazel试图变得聪明并且检测哪个工具链最适合用户，并且在您的情况下，它看起来像检测到适用于C ++和ObjC的工具链，但随后使用gcc与该工具链。这很奇怪，可能是向bazel报告问题的理由。

您能否确保使用最新的bazel和tensorflow，运行bazel clean --expunge，确保没有设置CC环境变量（或者如果您想使用gcc set BAZEL_USE_CPP_ONLY_TOOLCHAIN=1 env var），然后在tensorflow中运行./configure，然后构建？
