It's possible that this text only applied to ltilib 1.9.12, as 1.9.15
fixed the problems that we knew about, but it's also possible that there
are some more problems with gcc 4.1 and 4.2, but there is no release
For gcc 3.x I don't remember what happened, if lti 1.9.15 has any problem
with gcc 3.x. If your problem is that you want to switch compilers, you
have to switch the compiler for the whole of GridFlow, because of conflict
of C++ libraries (that could be avoided, but gcc/ld/libdl don't know how).
So you would redo ./configure, make, cd optional/rblti, make.
Besides, the lti support we have isn't so great, but most of all, ltilib
itself is in standby: no new 1.9 releases; 2.0 started long ago; 2.0 is
quite incompatible with 1.9; 2.0 is not getting released; ltilib's
mailing-list is less active than gridflow-dev.
In comparison, opencv has a lot of action. the mailing-list is comparable
in volume to pd-list. It seems also somewhat less complicated than ltilib
and it's a great occasion to get rid of a lot of ruby code (the ruby-to-pd
wrapper). however, opencv doesn't have all the features of ltilib and
ltilib doesn't have all the features of opencv.
I estimate that people will appreciate opencv support much more than
ltilib support. If there's anything of ltilib that one of us needs and
which is not in opencv, we will figure out a way to get the equivalent
feature or perhaps make a mini-ltilib source distribution containing only
what we can't find anywhere else.
Sorry for this news about ltilib support but this is a decision that had
to be made.
