The current version (which is a complete rewrite), although it is
technically beta, is vastly superior to 0.14.2, particularly in the area
of binaries, which, based on your earlier question, is relevant to you.
Here are the compile errors:
gcc -DHAVE_CONFIG_H -I. -I. -I../.. -I../.. -I/usr/local/include/pan -DGNOMELOCALEDIR=\""/usr/local/share/locale"\" -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/pango-1.0 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/freetype2 -I/usr/include/libpng12 -pthread -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/libxml2 -g -O2 -I. -c
msort.c
msort.c: In function ‘msort_with_tmp’:
msort.c:68: error: invalid lvalue in increment
msort.c:69: error: invalid lvalue in increment
msort.c:74: error: invalid lvalue in increment
msort.c:75: error: invalid lvalue in increment
This intrigued me, so as an experiment, I downloaded the source for
0.14.2 and tried to build it. Well, I get EXACTLY the same compile error
you do. Now I know that when 0.14.2 was current (which is almost 4 years
ago), I was able to compile it. I think the code has a subtle dependency
on whatever version of gcc was current at the time. So if you want to do
it just for the challenge of it, I can only speculate that you would
have to get an older gcc (and perhaps build it). Now I see no practical
reason for doing this (see my previous comment), but I have certainly
been known to do things like this just for the challenge, even when that
was the only reason.
The 4 offending lines involve constructs like (lines 68 and 69):
*((unsigned long int *) tmp)++ = *((unsigned long int *) b1)++;
Maybe there's compile switch that would make the current gcc (4.1.2)
accept that. I have also converted the offending lines to a more
simple-minded equivalent such that msort.c (and the rest of the source)
compiles cleanly with current gcc. I can give you details if you want.
