Hush cant replace lash for my situation

[Martinb_ARM_NOMMU_KISSDVD]

I did build the toolchain but i used a script, i will try to learn to build
my own uclibc but if i look at the buildscript and all the patches the
developers have used then i think i will never be able to do this (but i
will try, and will bug you on a new thread if im stuck)


I did remove the -DBB_NOMMU (dont remember why i ever put it ther in the
first place)
Did Comment out define debug_printf_exec and recompile
run it and type "ls". For me, it shows this:

===============================================
/hdd/shell # ls
parse_stream_outer: run_list
run_list entered
: run_list_real with 1 members
run_list_real start lvl 1
: rword=0 if_code=0 next_if_code=0 skip_more=12
: run_pipe_real with 1 members
run_pipe_real start: single_fg=1
: pipe member 'ls' '(null)'...
run_pipe_real return -1
: checkjobs returned 0
: setting last_return_code=0
: rword=0 if_code=0 next_if_code=0 skip_more=12
run_list_real lvl 1 return 0
run_list return 0
================================================



If i do the same on lash i get
================================================
/hdd/shell # ls
busybox  hush     lash     msh      stage2
================================================



i have a criple strace but im not sure if this wil give more help?

On the more extended note, I think it makes sense for you to learn
how to build YOUR OWN uclibc and toolchain instead of using
pre-packaged one. This can help checking whether this is a bug
in older uclibc, etc.

Start from:

http://busybox.net/~vda/HOWTO_bbox_with_uclibc.txt

I will try to help you if you hit a problem;
this will also help making this HOWTO more solid.
If you will do it and need to ask questions,
start a new thread (do not reply to this message).

..

Let's try to figure out what's going on (where it hits the problem).

hush.c has the following at the top:

/* If you comment out one of these below, it will be #defined later
 * to perform debug printfs to stderr: */
#define debug_printf(...)        do {} while (0)
/* Finer-grained debug switches */
#define debug_printf_parse(...)  do {} while (0)
#define debug_print_tree(a, b)   do {} while (0)
#define debug_printf_exec(...)   do {} while (0)
#define debug_printf_jobs(...)   do {} while (0)
#define debug_printf_expand(...) do {} while (0)
#define debug_printf_clean(...)  do {} while (0)

Comment out define debug_printf_exec:

//#define debug_printf_exec(...)   do {} while (0)

and rebuild busybox.

Now run it and type "ls". For me, it shows this:

$ ls
parse_stream_outer: run_list
run_list entered
: run_list_real with 1 members
run_list_real start lvl 1
: rword=0 if_code=0 next_if_code=0 skip_more=12
: run_pipe_real with 1 members
run_pipe_real start: single_fg=1
: pipe member 'ls' '(null)'...
execing 'ls'
