3 years ago Can you run with more debugging flags enabled to check if Python 3 is actually used? For example export EXTRA_BAZEL_ARGS="--subcommands --host_javabase=@local_jdk//:jdk".
The Python version in the SmartOS / Triton image is 3.7 btw.

3 years ago The Python version in the SmartOS / Triton image is 3.7 btw.
The same goes for my zone, but for good measure I tried with other versions too, including Python 2.7.

3 years ago Could you show what is in the generated py3wrapper.sh file? Especially around line 55. iirc the temporary files should still be there after running the bazel bootstrap script.
In the logs it says these generated files are in /tmp/. Do you perhaps have /tmp mounted with noexec?

The file gets deleted immediately so I'm unable to get its content. Is there a way to persist those temporary files?

/tmp is mounted on swap with read/write/setuid/nodevices/xattr but not noexec.

3 years ago I think that file gets generated from tools/python/pywrapper_template.txt. If you add set -x to the top of it all the commands executed by the script generated from that template should get printed.

Isn't there a Python installed in /opt/local/bin/python ? There is in my zone. That's also the Python I would expect Bazel to find.

Yes there is, both in /usr/bin (default OmniOS) and in /opt/local/bin (default pkgsrc).
The problematic part of the template seems to be this:
PYTHON_BIN="$(PATH="$PATH" which python%VERSION% 2> /dev/null)"
USED_FALLBACK="0"
if [ -z "${PYTHON_BIN:-}" ]; then
PYTHON_BIN="$(PATH="$PATH" which python 2>/dev/null)"
USED_FALLBACK="1"
fi
if [ -z "${PYTHON_BIN:-}" ]; thenWhich corresponds in execution to:
+ which python3
+ 2> /dev/null
+ PYTHON_BIN=''
+ USED_FALLBACK=0
+ [ -z '' ]
+ which python
+ 2> /dev/null
+ PYTHON_BIN=''
+ USED_FALLBACK=1
+ [ -z '' ]As you can see PYTHON_BIN always ends up empty, but if I run PATH="$PATH" which python3 2>/dev/null or PATH="$PATH" which python 2>/dev/null in sh it outputs correctly /usr/bin/python.
I am trying to build Bazel in a pkgsrc branded zone on OmniOS. This should be the same as building in a Joyent zone on SmartOS. I follow your steps precisely but I get
Forcing Python3 or Python2 with --host_force_python=PY3 (respectively PY2) results in the exact same error message with py3wrapper.sh and py2wrapper.sh
