With Debian unstable as of today, the same still happens.
Steps to produce an mksh executable:
% env CVS_RSH=ssh cvs -d _anoncvs at anoncvs.mirbsd.org:/cvs \
co -PA mksh
% cd mksh
% env CC=klcc CPPFLAGS=-DMKSH_NO_LIMITS sh Build.sh -r
Then, ?./test.sh -v? fails, as does this:
tg at frozenfish:~/mksh $ ./mksh -c 'echo foo; ls; echo bar'
foo
Build.sh check.t eval.c expr.o jobs.c lex.o mksh
sh_flags.h syn.c var.c
CVS dot.mkshrc eval.o funcs.c jobs.o main.c mksh.1 shf.c
syn.o var.o
Makefile edit.c exec.c funcs.o lalloc.c main.o setmode.c shf.o
test.sh var_spec.h
Rebuild.sh edit.o exec.o histrap.c lalloc.o misc.c setmode.o
signames.inc tree.c
check.pl emacsfn.h expr.c histrap.o lex.c misc.o sh.h
strlcpy.c tree.o
^C
I?d greatly appreciate if someone could look into this (it
used to work with earlier klibc versions, but they had the
kernel header (getrusage) and missing function issues that
have been fixed in later versions ? now only {g,s}etrlimit
are missing, hence -DMKSH_NO_LIMITS).
I?d really like to get rid of dietlibc on most architectu-
res for /bin/mksh-static and use klibc instead, it appears
to be better working and more actively maintained. (Maybe,
with mksh R40, which will have transitions in functionali-
ty, which is why I?d not recommend to do it before that, I
can convince you to drop the in-klibc dash in favour of my
shell? who knows.)
Thanks,
