Dear Perl-Inline users,
There currently is an open bug report (RT# 42786) for Inline::BC. I've decided
to take on this task and intend to release version 0.08 at some stage. The
current state is that I now have the source code modifications in place to load
BC's math library from Inline::BC.
I've introduced a new config option called "MATH_LIB" to accept values of only
0 or 1. So, to use Inline::BC with BC's math library you would have to specify
something like:
use Inline BC => 'DATA', MATH_LIB => 1;
This works great on the Perl file (sinhcalc.pl) that I originally posted.
However, a number of tests in the Inline::BC test suite are now failing. So
there is a bit more work for me to do before releasing ver. 0.08.
Cheers, Ron.
