Hi Steve,
Many thanks for your response to my problem.
This is clearly both the cause, and correct solution.
I am puzzled by why you had to rebuild the "c" source though. I will see
what happens to me.
I trust that your fix will be incorporated into Poplog V17.
Aaron has asked for my fixes which I will supply.
I am pleased that my thinking was not too far adrift.
Many thanks
Dave

for 64bit on Linux Mint V19

I can compile as directed for 64 bit - so far so good, but when I use
mkpopvision to build the package I get the following mishap:-
It appears that bytevec is already compiled into the Poplog base image,
which presumably post-dates popvision. I have tracked the declaration down
to $popsrc/initvec.p, where it is consistent with the definition in
$popvision/lib/newbytearray.p i.e. both are:
defclass bytevec :byte;
I think the preferred fix is to adopt the definitions in $popsrc/intvec.p.
This involves 3 changes:
1. Modify $popvision/lib/newbytearray.p to remove the definition of bytevec.
2. Modify $popvision/lib/array_random.p to remove the definition of
ushortvec, which is also built-into Poplog.
3. Modify $popvision/lib/arraylookup.p to rename isbytevec to (say)
isbytevecclass. This is evidently is a long-standing infelicity in the code
in which the definition for isbytevec that is introduced in newbytearray.p
is locally and probably inadvertently overridden.
I also found it was necessary to recompile the *.o files on my system. There
are some scripts supplied for this. The important thing to remember is that
the scripts should be run in $popvision/lib e.g.
cd $popvision/lib
../lib/compile_popvision_gcc
(These scripts could do with a bit of a general tidy-up and integration.)
I attach a zip file of my suggested changes that should be unpacked in
$popvision/lib.
Steve
