Hi Konrad,
Thanks, that helps a lot. It works! I used straight split() which
prevented the first value from being null.
Yes, I agree less pythonic :) The only recipe I've seen building gn
based projects is OSSystem's meta-browser/chromium. I followed it's
pattern, as the Flutter Engine is a derivative of Chrome.
The issue with these large gn based projects is that they're self
contained builds. A build system within a build system. I must admit
though the gclient DEPS download scheme is efficient. I initially
looked at parsing out the DEPs file into a large SRC_URI list, but
quickly hit Yocto serializing them. Perhaps OE could benefit from
tighter integration with gn.
perhaps a generic gn class might be helpful, there have been attemps to
add depot_tools/glient to fetchers in past but there is no consistent
apis there, it kept on changing in myriad different ways. gn is more or
less same story, its too tightly integrated into the software its
building, we should abstract it if we can.
I'm open to any other alternative approaches.
Cheers,
Joel

Hi Joel,
okay, I see - although I have to admit the argparse idea looks very
weird, the error is that according to
https://docs.python.org/3/library/argparse.html#argparse.ArgumentParser.parse_args
the pkgconfig_args variable should be a list not a single string.
so doing pkgconfig_args = d.getVar("PACKAGECONFIG_CONFARGS").split("
") should fix the issue.
But from a bitbake perspective you should really think about
choosing a less pythonic version
Best

Hi Konrad,
I left out the details of the path encoding :) Effectively I was
attempting to duplicate get_out_dir() as found here:
https://github.com/flutter/engine/blob/master/tools/gn
My recipe is here:

What about
do_configure() {
cd ${@bb.utils.contains('PACKAGECONFIG_CONFARGS',
'--verbose', out/verbose', 'out', d)}
}

Hello,
I'm trying the below in a recipe. Bitbake gives me: ERROR:
Unable to parse ...: Exited with "2"
inherit python3native
require utils.inc
do_configure() {
cd ${@get_out_dir(d)}
}
(in utils.inc)
def get_out_dir(d):
import os
import argparse
pkgconfig_args = d.getVar("PACKAGECONFIG_CONFARGS")
parser = argparse.ArgumentParser()
parser.add_argument("--verbose", help="increase output
verbosity",
action="store_true")
args = parser.parse_args(pkgconfig_args)
if args.verbose:
return os.path.join('out', 'verbose')
return 'out'
What am I doing wrong, or is there a better way? Seems like
it doesn't like "args = parser.parse_args(pkgconfig_args)"
The output directory is a combination of the arguments.
Thanks!
Joel
