From 154af50ed7ed8b91838d713052ebf29b0b14f765 Mon Sep 17 00:00:00 2001 From: Andre McCurdy Date: Mon, 18 Jan 2016 11:00:00 -0800 Subject: [PATCH] mpers.m4: more robust test for -m32/-mx32 compile support When using the default OE toolchain for x86-64, the basic checks for -m32 and -mx32 compile support in mpers.m4 pass but later attempts to actually use the toolchain with -m32 fail, e.g. | In file included from /home/andre/build/tmp/sysroots/qemux86-64/usr/include/sys/syscall.h:31:0, | from ../strace-4.11/defs.h:55, | from mpers-m32/kernel_dirent.c:32: | /home/andre/build/tmp/sysroots/qemux86-64/usr/include/bits/syscall.h:41:29: fatal error: bits/syscall-32.h: No such file or directory Make the mpers.m4 tests more robust so that configure correctly detects the limitations of the OE toolchain.
