| 4 | Subject: [PATCH] mpers.m4: more robust test for -m32/-mx32 compile support |
| 5 | |
| 6 | When using the default OE toolchain for x86-64, the basic checks for |
| 7 | -m32 and -mx32 compile support in mpers.m4 pass but later attempts to |
| 8 | actually use the toolchain with -m32 fail, e.g. |
| 9 | |
| 10 | | In file included from /home/andre/build/tmp/sysroots/qemux86-64/usr/include/sys/syscall.h:31:0, |
| 11 | | from ../strace-4.11/defs.h:55, |
| 12 | | from mpers-m32/kernel_dirent.c:32: |
| 13 | | /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 |
| 14 | |
| 15 | Make the mpers.m4 tests more robust so that configure correctly |
| 16 | detects the limitations of the OE toolchain. |
