I am seeing the following plpgsql compile failure in CVS:
#$ gmake
bison -y -d gram.y
NONE:0: /usr/contrib/bin/gm4: ERROR: EOF in string
sed -e 's/yy/plpgsql_yy/g' -e 's/YY/PLPGSQL_YY/g' < y.tab.c >
./pl_gram.c
/bin/sh: cannot open y.tab.c: no such file
gmake: *** [pl.tab.h] Error 2
I believe it is related to this commit:
revision 1.41
date: 2003/03/25 03:16:40; author: tgl; state: Exp; lines: +29 -6
plpgsql can assign to subscripted variables now, e.g.
x[42] := whatever;
The facility is pretty primitive because it doesn't do array slicing and
it has the same semantics as array update in SQL (array must already
be non-null, etc). But it's a start.
I have attached the change --- anyone see the cause? I have bison 1.75.
