Short version: I'm attaching a patch for aclocal.m4, but
please proofread it to make sure it does the right thing.
Longer version:
Hi! I just tried building Lynx 2.8.8rel.2, and got error
messages similar to the ones in:
https://lists.nongnu.org/archive/html/lynx-dev/2010-09/msg00000.html
specifically, "has no left operand" errors like:
../../../WWW/Library/Implementation/HTUtils.h:534:19: error: operator '==' has
no left operand
../../../WWW/Library/Implementation/HTUtils.h:540:21: error: operator '==' has
no left operand
../../../WWW/Library/Implementation/HTUtils.h:557:19: error: operator '>' has
no left operand
../../../WWW/Library/Implementation/HTUtils.h:572:20: error: operator '==' has
no left operand
../../../WWW/Library/Implementation/HTUtils.h:578:22: error: operator '==' has
no left operand
../../../WWW/Library/Implementation/HTUtils.h:595:20: error: operator '>' has
no left operand
I eventually traced this to a bunch of SIZEOF_* macros (e.g.,
SIZEOF_INT): 'configure' that comes with the distribution has
#define SIZEOF_INT $ac_cv_sizeof_int
first, but then it checks to make sure that $ac_cv_sizeof_int is
defined, and is an integer. That is, it writes SIZEOF_INT to config.h
first, and only then checks the value that it wrote. In my case,
$ac_cv_sizeof_int was blank, and so I was winding up with SIZEOF_INT
set to the empty string, and thus the "has no left operand" errors,
above.
I'm attaching a patch that just swaps the order of the two
operations. But I haven't been able to find a copy of the autoconf
that was used to build this distribution, so I'd appreciate someone
else checking it.
Thanks,
