I am having a problem getting GNUgrep to work on my poor system. I have a
Compaq 286 running SCO Xenix 2.3. Any help that can be pointed my way I
would greatly appreciate. Error description follows:
I have found a suspicous construction in the gnugrep file dfa.h. It states:
----------------------------------------------------------------------
typedef struct
{
unsigned index:24, /* Index into the parse array. */
constraint:8; /* Constraint for matching this position. */
} _position;
----------------------------------------------------------------------
Isn't the storage class for unsigned the same as unsigned int, and if this
is so then a total of 32 bits are being assigned to the storage allocated
for this structof ~16 bits. Needless to say, the compiler grumbles with the
error:
----------------------------------------------------------------------
cc -O -DUSG -i -F 8000 -c grep.c
grep.c
dfa.h(384) : error 34: `index' : field type too small for number of bits
*** Error code 1
Stop.
----------------------------------------------------------------------
If the structure is changed to read:
----------------------------------------------------------------------
typedef struct
{
unsigned long index:24; /* Index into the parse array. */
unsigned constraint:8; /* Constraint for matching this position. */
} _position;
-or-
typedef struct
{
unsigned long index:24, /* Index into the parse array. */
constraint:8; /* Constraint for matching this position. */
} _position;
----------------------------------------------------------------------
Then the result is:
----------------------------------------------------------------------
cd tests; sh regress.sh
egrep: Regular expression too big
cmp: EOF on khadafy.out
Khadafy test failed -- output left on khadafy.out
Spencer test #30 failed ... Spencer test #35 failed
Spencer test #37 failed
Spencer test #41 failed ... Spencer test #47 failed
Spencer test #72 failed ... Spencer test #76 failed
Spencer test #83 failed ... Spencer test #87 failed
Spencer test #92 failed
Spencer test #95 failed ... Spencer test #115 failed
Spencer test #118 failed
Spencer test #121 failed
*** Error code 1
Stop.
----------------------------------------------------------------------
Running the tests also dumped the core, a stack re-trace of which reads:
----------------------------------------------------------------------
_reganalyze() from _regcompile+0xe5
_regcompile(0xb130, 0xa, 0xb70, 0x1) from _main+0x4e3
_main(0x3, 0xb106, 0xb10e) from __start+0x32
__start() from start0+0x5
----------------------------------------------------------------------
