From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Humberto Alves Date: Thu, 1 Sep 2022 20:25:11 +0100 Subject: [PATCH] Tweak `setup.py` sysroot detection When crosscompiling, the Python installer expects the C compiler to be invoked with a `--sysroot` command line option, which then is used to find additional subdirectories containing headers and libraries. Because there is no such option present, this is a workaround to use the environment variable `SERENITY_INSTALL_ROOT` as a fake `--sysroot` in the detection code. --- setup.py | 2 ++ 1 file changed, 2 insertions(+) diff --git a/setup.py b/setup.py index e651ac7627e8b796f8b9b4d60f592bc9261b6540..c4c4e92309a952a88d9de1b853a9535cb86913cc 100644 --- a/setup.py +++ b/setup.py @@ -166,6 +166,8 @@ def sysroot_paths(make_vars, subdirs): for var_name in make_vars: var = sysconfig.get_config_var(var_name) if var is not None: + if serenity_install_root := os.environ.get('SERENITY_INSTALL_ROOT'): + var += f' --sysroot={serenity_install_root}' m = re.search(r'--sysroot=([^"]\S*|"[^"]+")', var) if m is not None: sysroot = m.group(1).strip('"')
