From: David Owens Date: Thu, 12 Jul 2018 16:37:34 +0000 (-0500) Subject: libglib2: Avoid absolute path to python in shebang X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3ab5dfb548a840debe6e4e767ea2ea10e9c6e93a;p=buildroot.git libglib2: Avoid absolute path to python in shebang When the output directory is nested under a long path name, calling the gdbus-codegen, glib-genmarshal, or glib-mkenums scripts throws the error: > '/usr/bin/env: /...: No such file or directory' This is because libglib2 uses the absolute path to the python interpreter for its shebang statements, and shebangs have a max length of 127 chars[1]. A long absolute path will be cut off and appear as a missing file. Since the host Python is present in the $PATH passed to all packages, we can copy the workaround from Yocto and just use the python interpreter in $PATH[2]. However, 'python' is used instead of 'python3' as the scripts are compatible with both.
