Re: compiling Perl on Win32 so I can use Inline::C

I have no experience in compiling perl. However, I find that your statement of "I'm processing binary data" sets off a trigger with me. Perl has facilities for dealing with binary data. I've written a couple of modules at work to do just that. You don't need C to do this, so if that's your only reason for this trek, perhaps you could pose your problem for the monks at large to answer...

Re^2: compiling Perl on Win32 so I can use Inline::C by diana (Initiate) on Mar 03, 2005 at 01:47 UTC
Why thank you, kind thor. Can Perl read one byte at a time, do bit-shifts and ands and ors to find a sync pattern, and then translate the binary to hex and then apply a decimal conversion formula to that hex data? And fast? If so, then no, I don't need C. (I'm processing frames of spacecraft telemetry in a sort of home-grown, let's figure out how to do this ourself research atmosphere)	[reply]

In one word, YES. Read 1 byte at a time: `read() # when reading from a file, or unpack() # using b or B in the template when reading from a string` [download] Bit shift left 3 bits: `$a = $b << 3;` [download] Bit shift right 2 bits: `$a = $b >> 2;` [download] Bitwise AND: `$c = $a & $b;` [download] Bitwise OR: `$c = $a \| $b;` [download] Bitwise XOR: `$c = $a ^ $b;` [download] Binary to hex conversion (4 bits at a time): `$hex =~ s/([01]{4})/sprintf("%.1x", eval('0b'.$binary))/eg;` [download] (or something similar using the sprintf function) -------------------- mlh2003	[reply] [d/l] [select]
