            Bug ID: 12331
           Summary: meson issue
           Product: buildroot
           Version: 2019.02.7
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Other
          Assignee: unassigned at buildroot.uclibc.org
          Reporter: jpcartal at free.fr
                CC: buildroot at uclibc.org
  Target Milestone: ---

Meson script uses full path to python3 when executed which gives errors when
the path is too long :

$ cat host/bin/meson 
#!/home/Dev/Ssd/buildroot/buildroot-2019.02.7/host/bin/python3
# EASY-INSTALL-ENTRY-SCRIPT: 'meson==0.49.0','console_scripts','meson'
__requires__ = 'meson==0.49.0'
import re
import sys
from pkg_resources import load_entry_point

if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
    sys.exit(
        load_entry_point('meson==0.49.0', 'console_scripts', 'meson')()
    )

Yes, I also encountered this error. What I did so far to work around it is:

define HOST_MESON_FIXUP_SHEBANG
        $(SED) 's%^#!.*%#!/usr/bin/env python3%' $(HOST_DIR)/bin/meson
endef
HOST_MESON_POST_INSTALL_HOOKS += HOST_MESON_FIXUP_SHEBANG

in package/meson/meson.mk.

Looking back at this, your path
"/home/Dev/Ssd/buildroot/buildroot-2019.02.7/host/bin/python3" is not that
long, it's only 61 bytes long. This shouldn't cause a problem, the maximum
shebang line is 128 bytes.

So I'm not sure why you think the length of the path is a problem. Could you
give more details about the error you're seeing ?

My bad, I removed parts of the path, so it seems shorter that the maximum
allowed, but the real problem is indeed the length and your patch solved it.

Regards.

I've sent a tentative patch to the list:
https://patchwork.ozlabs.org/patch/1222257/

It's not unlike Thomas' proposal, but with my little touch... ;-)
