A while ago I posted an implementation of egrep that I had found in
comp.sources.unix on uunet.uu.net. After working with it quite a bit,
though, I discovered that it was designed to be an add-on for a system
that had an existing egrep (bleh!). So, if you grabbed the egrep
I posted a while ago, it's probably a good idea to blow it away :-(
I obtained the GNU grep package, and it includes what looks like a full
implementation of egrep. It compiled under MINIX using gcc without many
troubles other than the little problems with MINIX's include files.
Apologies to the net for wasting bandwidth.

I've been trying to get GNU E?REP to compile under the ACK C compiler: after a while, I got it to work, but it seems to be having problems with MALLOC, even when I give it 4 MEG! Ha anybody already done this port? I have it running, but it crashes unpredictably, and with no debugger...

Hmm. I compiled this source under MINIX-386 using gcc, and it's worked fine just chmem'ed =65536. I assume you're using ACK on a 68000-based machine, so I don't have much in the way of clues for you. -- Guy Helmer, Dakota State University Computing Services helmer@sdnet.bitnet, dsuvax!ghelmer@wunoc.wustl.edu, wupost!dsuvax!ghelmer "I'm a cowboy, on a keyboard I ride..." -- with apologies to Bon Jovi

Never mind. GNU E?REP assumes 4 byte integers, and ther are all kinds of magic numbers in the code like 28 which means that unless I rewrite the whole thing, it won't work. I'm sure it's easier to re-compile under GCC. Too bad they didn't use LONG instead of INT where it was neede, not every C has 32 bit ints...

With 16-bit ints, you cannot malloc more than 64K in a single call even if you chmem' the program to 4GByte. C.v.W.

However, I had it around for a long time, so it may be an ancient version...

I basically got GNU E?REP working by some tweaking of the code: the fact that size_t is a 16 bit integer can cause problems, and th E?REP code does some strange things. It isn't in a postable form yet, though... If I get enough interest (i.e. email) I'll post a diff file from e?rep 1.3
