| 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. |
