From d99e19418f984066fffb28717730bb8f03a65333 Mon Sep 17 00:00:00 2001 From: Tim Orling Date: Mon, 30 Mar 2020 19:09:36 -0700 Subject: lib/oe/utils.py: add get_host_compiler_version() Add helper function to get the host compiler and version. Do not assume compiler is gcc. NOTE: cannot set env to d.getVar("PATH") as that does not contain the session PATH which was set by environment-setup-... which breaks the install-buildtools use-case Signed-off-by: Tim Orling --- meta/lib/oe/utils.py | 31 +++++++++++++++++++++++++++++++ 1 file changed, 31 insertions(+) diff --git a/meta/lib/oe/utils.py b/meta/lib/oe/utils.py index 9042b370f7..13f4271da0 100644 --- a/meta/lib/oe/utils.py +++ b/meta/lib/oe/utils.py @@ -373,6 +373,37 @@ def format_pkg_list(pkg_dict, ret_format=None): return output_str + +# Helper function to get the host compiler version +# Do not assume the compiler is gcc +def get_host_compiler_version(d, taskcontextonly=False): + import re, subprocess + + if taskcontextonly and d.getVar('BB_WORKERCONTEXT') != '1': + return + + compiler = d.getVar("BUILD_CC") + # Get rid of ccache since it is not present when parsing. + if compiler.startswith('ccache '): + compiler = compiler[7:] + try: + env = os.environ.copy() + # datastore PATH does not contain session PATH as set by environment-setup-... + # this breaks the install-buildtools use-case + # env["PATH"] = d.getVar("PATH") + output = subprocess.check_output("%s --version" % compiler, \ + shell=True, env=env, stderr=subprocess.STDOUT).decode("utf-8") + except subprocess.CalledProcessError as e: + bb.fatal("Error running %s --version: %s" % (compiler, e.output.decode("utf-8"))) + + match = re.match(r".* (\d+\.\d+)\.\d+.*", output.split('\n')[0]) + if not match: + bb.fatal("Can't get compiler version from %s --version output" % compiler) + + version = match.group(1) + return compiler, version + + def host_gcc_version(d, taskcontextonly=False): import re, subprocess -- cgit 1.2.3-korg
