From a9d8bc98061c2c4bce312ce4d63cb4c61889fb6d Mon Sep 17 00:00:00 2001 From: Loïc Minier Date: Wed, 19 Jan 2011 13:16:29 +0100 Subject: Don't add symlink in srctree when using an objtree MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When building with srctree != objtree, the build creates arch/soc/cpu specific symlinks in the source tree. This means that the same source tree can't be used for multiple builds at the same time. Also, these symlinks in the source tree are only cleaned up if one passes the same O= to distclean. When srctree != objtree, mkconfig creates an $objtree/include2 directory in the objtree to host the asm -> arch/$arch/include/asm symlink so that "#include " can be used. But it also creates another identical symlink in $objtree/include. Then, mkconfig creates two symlinks: $objtree/include/asm/arch -> arch/$arch/include/asm/arch-$cpu (or $soc) $objtree/include/asm/proc -> arch/$arch/include/asm/proc-armv (on arm) but because $objtree/include/asm points at $srctree already, the two symlinks are created under $srctree. To fix this, create a real $objtree/include/asm directory, instead of a symlink. Update cleanup code accordingly.
