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

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')()
    )

--- Comment #1 from Thomas Petazzoni <[email protected]> --- 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.

--- Comment #2 from Thomas Petazzoni <[email protected]> --- 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 ?

--- Comment #3 from Jean-pierre Cartal <[email protected]> ---
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.

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