Problem description (include actual vs expected text, if applicable):

Hello, I am working on an embedded project developing both on windows 11 and ubuntu 20.04 machines. I set up custom toolchains for both machines, the compiler being tiarmclang.

When I try to build my project on a windows machine with bazel build --config=clang_config --cpu=cortex-m4 :osal everything works fine and the project is correctly build.

When I try to build it on the linux machine with bazel build --config=clang_config_linux --cpu=cortex-m4 :osal I get the following error:

ERROR: /home/paolo/Documents/Projects/atacama/source/atacama/platform/osal/src/BUILD.bazel:5:11: Compiling atacama/platform/osal/src/osal.c failed: (Exit 1): linux-sandbox failed: error executing

I tried as a test to copy the folder 'external' and all of its content inside the sandbox and now bazel can find the compiler. Why is this happening?

Where do you see this issue? (include link to specific section of the page, if applicable)

No response

Any other information you'd like to share?

What are your configurations (bazel build --config=clang_config)? What is the Bazel version you're using? Bazel 7 uses toolchain resolution by default so --cpu=cortex-m4 might not work anymore. Can you provide logs with --verbose_failures (and without --sandbox_debug).

PaoloMattachini commented 10 months ago

clang_config and clang_config_linuxare defined in .bazelrc file which looks as follow:

build:clang_config --crosstool_top=@tiarm-compiler//ti-cgt-armllvm_2.1.1.LTS-windows:ticlang_suite build:clang_config_linux --crosstool_top=@tiarm-compiler-linux//ti-cgt-armllvm_3.2.1.LTS-linux:ticlang_suite build:clang_config build:clang_config_linux build:clang_config --host_crosstool_top=@bazel_tools//tools/cpp:toolchain/ti-cgt-armllvm_2.1.1.LTS-windows build:clang_config_linux --host_crosstool_top=@bazel_tools//tools/cpp:toolchain/ti-cgt-armllvm_3.2.1.LTS-linux

Hello, any update on this?

PikachuHyA commented 4 months ago

I suspect that the external compiler files are not being placed into the sandbox. Based on the log:

src/main/tools/linux-sandbox-pid1.cc:518: "execvp(external/tiarm-compiler/ti-cgt-armllvm_3.2.1.LTS-windows/bin/tiarmclang, 0xb70150)": No such file or directory

Could you please check if the file external/tiarm-compiler/ti-cgt-armllvm_3.2.1.LTS-windows/bin/tiarmclang exists in your bazel-<your workspace name> folder?

Thank you!
