From ff3bcb17f43631e5637a67df56aec6e8b8733ec4 Mon Sep 17 00:00:00 2001 From: =?utf8?q?S=C3=A9bastien=20Szymanski?= Date: Fri, 23 Feb 2024 12:42:06 +0100 Subject: [PATCH] Makefile: pass -undef option to cmd_gen_envp MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Without the '-undef' option, the 'linux' string in .env files is replaced with the string '1 '. For example, in the board/armadeus/opos6uldev/opos6uldev.env file, kernelimg=opos6ul-linux.bin becomes kernelimg=opos6ul-1 .bin in the include/generated/env.in file. That's because 'linux' is a System-specific Predefined Macros. [1] Pass the '-undef' option to fix this issue.
