From 53cc748b93e8af584557d6db5309c3e955182c5c Mon Sep 17 00:00:00 2001 From: Bruce Ashfield Date: Thu, 10 Jan 2013 15:49:16 -0500 Subject: linux-libc-headers: fix headers install in long path name environments If a build is started in a deep directory structure, or in a path with long directory names the installation of linux-libc-headers will fail with: | make[2]: execvp: /bin/sh: Argument list too long | make[2]: *** >From within the kernel Makefiles themselves. The solution is to patch the kernel build rules with the following change: [ scripts/Makefile.headersinst: install headers from scratch file If headers_install is executed from a deep/long directory structure, the shell's maximum argument length can be execeeded, which breaks the operation with: | make[2]: execvp: /bin/sh: Argument list too long | make[2]: *** By dumping the input files to a scratch file and using xargs to read the input list from the scratch file, we can avoid blowing out the maximum argument size and install headers in a long path name environment. ] Until this change, or a similar one, is merged into the mainline kernel, this change should be applied to any 3.7 or greater libc-headers build.
