I am building something that seems to be an IRC chat client...

I have managed to do all connections and send and receive text from the server. However, the difficult part is to actually process the received messages.

I figured out I need regular expressions for this, only I don't know how to implement them! Installing Boost (which has regular expressions) is a pain in the butt for OS X, so can anyone provide me with a cross-platform regular expression Library?

I am using OS X, so Windows specific answers will not help.

use boost Regular Expressions, but I don't know if it supports your os or not. Probably does because it can be compiled for both *nix and MS-Windows. Read all about boost libraries here.

I can recommend PCRE.

I don't want to use boost. It is a pain in the butt to install. And Ooble's recommendation was nice, but it didn't work for me, because for some reason, because the script fails to install the .profile file inside my user directory. So, I can't install anything.

Thanks! At least that was installed. How can I find a tutorial or any documentation on how to use this library with C++? What headers do I need to include?

Have a look at the pcrecpp.h file - it should be in the pcre directory. It is a wrapper for use with c++. This makes it a lot easier to use the library. There is a lot of instructions and examples in the .h file.

I am using OS X. Could you be more specific? If you are using windows, where do you find those files on windows? It may help me with this...

Installing Boost is easy with MacPorts.

Soulstorm · Mar 27th, 2008, 3:53 AM

What do you mean by that? To just throw the folder into my project and just type "include "pcre.h""?

Actually, I am trying to do this, but it always complain about files it can't find!

Ooble · Mar 27th, 2008, 7:56 AM

What complaints do you get? Are they compiler errors or linker errors?

Soulstorm · Mar 27th, 2008, 8:01 AM

It just can't find the file "pcre.h"

Also, I noticed something strange. This thing happens to me only using Xcode. Using the command line, all headers are included correctly, and the compiler encounters no error at all! Any ideas?
