RE: Converting From C to Perl

Hi there,

I'm currently working on neural network project. The program i'm using
(SNNS) will automaticly create a network as a c function which can be
called.

I know there are tools for converting Perl into C but I was wondering if
there were any which worked the other way round.

Thanks for your help

Don't you rather want to *call* the C function from Perl? Automatically
generating C code and translating that into Perl sounds like too strange
a concept. What would a conversion buy you, except a slowdown by 5 or 10?

Inline::C is good at making C programs callable from Perl. If the function
is in a library and you have a header file for it, with a little luck
it does it all by itself, but even if it doesn't, it's usually easy.

Thanks for the advice, I have looked into the inline module and it seems to
do what I want. The only drawback is that i will need to install Visual
Studio for it to work.

It looks like there is the option of using other utilities but they require
Perl being re-installed.

Ah well, trying to track down visual studio now.

Cheers

Steve

Uhm. Why? Inline::C just needs a C compiler. It certainly doesn't need
the bloat that is MS Visual Studio. Grab yourself a copy of the GNU C
compiler and install that. You don't need an entire IDE to use Inline::C.
