[daimagou]

Description of the problem / feature request:

Use --sandbox_debug to see verbose messages from the sandbox
Error: SDKROOT not set.
external/local_config_cc/cc_wrapper.sh: line 58:  6153 Abort trap: 6           "$(/usr/bin/dirname "$0")"/wrapped_clang "$@"

Feature requests: what underlying problem are you trying to solve with this feature?

manual export SDKROOT and DEVELOPER_DIR  env in external/local_config_cc/cc_wrapper.sh 

Bugs: what's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

build an executable file for ios/macos

What operating system are you running Bazel on?

ProductName: Mac OS X
ProductVersion: 10.15.3
BuildVersion: 19D76

Have you found anything relevant by searching the web?

#11716

Any other information, logs, or outputs that you want to share?

// Returns the DEVELOPER_DIR environment variable in the current process
// environment. Aborts if this variable is unset.
std::string GetMandatoryEnvVar(const std::string &var_name) {
  char *env_value = getenv(var_name.c_str());
  if (env_value == nullptr) {
    std::cerr << "Error: " << var_name << " not set.\n";
    abort();
  }
  return env_value;
}

any update for this issue ,

sames caused by upgrade the lastest xcode

[susinmotion]

It looks like the installation might be incomplete and/or Bazel might be looking in the wrong place for the developer tools.

Could you try if you haven't:
accepting the license?
installing the command line tools for the new Xcode version?
using --xcode_version or xcode-select to point to the new Xcode version?
running blaze shutdown?

@susinmotion thank you for your reply，I tried the method you said, but there is still the same problem

add more info:

1.Env can be found in the compile stage

(cd /private/var/tmp/_bazel_xxx/19af71a3f2eee621aed0a0ca59e12662/execroot/xxxx && \
  exec env - \
    APPLE_SDK_PLATFORM=iPhoneOS \
    APPLE_SDK_VERSION_OVERRIDE=13.6 \
    PATH=/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Apple/usr/bin \

  .....

  ...../utils.cpp -o bazel-out/ios_arm64-opt/bin/..../utils.o

2. Env cannot be found in the executable file generation stage

 (cd /private/var/tmp/_bazel_mac_ci/19af71a3f2eee621aed0a0ca59e12662/execroot/xxxx && \
 exec env - \
 external/local_config_cc/cc_wrapper.sh bazel-out/ios_arm64-opt/bin/xxxxx/libmy_test.internal_cc_library.a 
 ....

I don’t understand why it will be different at different stages

[susinmotion]

Ahhh thanks for looking into this. The "missing env" issue is real. It's this one: #12049.

But I still think there might be something else going on here... Passing to cc rules for more input.

FWIW with my issue I've never seen an action not get the apple env that requires it.
