Re: Bug#925358: klibc: built program on m68k terminates with signal 9 (SIGKILL)

Hi Adrian,

sure: it’s the
	Total failed: 3 (3 unexpected)
in the build log, and before that:

        Description:

The trick here is that the faulty binary is not included in
the .deb package thanks to the testsuite failure, so it’s
not all that easy.

Recompiling the .dsc would trigger it though (expect that to
take a couple of hours, perhaps a day…).


You *might* be able to trigger it with:

$ apt-get source mksh
$ cd mksh-*/
$ env LC_ALL=C HAVE_CAN_WALL=0 HAVE_LIBUTIL_H=0 CC=klcc \
    HAVE_CAN_FSTACKPROTECTORSTRONG=0 HAVE_CAN_FSTACKPROTECTORALL=0 \
    CFLAGS='-fstack-protector-strong -Wformat -Werror=format-security -Wall -Wextra -g -fno-stack-protector -Os' \
    CPPFLAGS='-Wdate-time -D_FORTIFY_SOURCE=2 -DMKSH_BINSHPOSIX -DMKSH_BINSHREDUCED -DMKSH_SMALL -DMKSH_SMALL_BUT_FAST' \
    LDFLAGS='-Wl,-z,relro -Wl,-z,now -Wl,--as-needed' \
    LDSTATIC=-static LIBS= sh Build.sh -r && \
  perl check.pl -s debian/mtest.t -p ./mksh -v

This should do roughly the same as the package build does in that
place, although I’m not sure I caught all exports.


Thanks,

When he found out that the m68k port was in a pretty bad shape, he did
not, like many before him, shrug and move on; instead, he took it upon
himself to start compiling things, just so he could compile his shell.
How's that for dedication. -- Wouter, about my Debian/m68k revival
