Compiling flexc++ from source (in Ubuntu Precise)

Jurjen Bokma

February 2012

	Note
	As of this writing, flexc++ has been out less than a week. So you may want to try just installing it with the package management system, instead of rushing in an following the steps below.

	Note
	This section is already outdated. Flexc++ is available from Debian Sid, and the Sid package can be installed in Precise.

Procedure 22. BobCat

Fetch
Flexc++ won't compile with the BobCat that comes with Precise. So we fetch its latest version
Installing some necessary packages

apprentice@testbox:~$ sudo apt-get install -y icmake libreadline-dev libx11-dev libssl-dev
Untarring

tar zxf bobcat_2.21.01.orig.tar.gz cd bobcat-2.21.01
Editing INSTALL.im
The file INSTALL.im contains the install path /usr. Change it to /usr/local like this:
```
<snip>
void setLocations()
{
BASE  = "/usr/local";
<snip>
	
```
Building

apprentice@testbox:~$ ./build libraries The class FBB::Xpointer can only be compiled if you have installed the file X11/Xlib.h. To use the class Xpointer, programs using Xpointer objects must also be linked against the X11 library: -lX11 -lbobcat The class FBB::Xpointer can safely be left out of the bobcat library if you're not planning to construct programs using Xpointer. Press Enter y if you WANT to compile the files of the class FBB::Xpointer. Press Enter or any other line if you DON'T WANT to include the class FBB::Xpointer in the bobcat library. y The SSL classes can only be compiled if you have installed the libssl-dev development library, containing files like /usr/include/openssl/bn.h. To use objects from openssl programs must also be linked against the openSSL library: -lssl -lbobcat The SSL classes can safely be left out of the bobcat library if you're not planning to construct programs using them. Press Enter y if you WANT to compile the files of the SSL classes Press Enter or any other line if you DON'T WANT to include the SSL classes in the bobcat library. y The classes using the readline library can only be compiled if you have installed the libreadline-dev development library, containing files like /usr/include/readline.h. To use objects of these classes in your programs, your programs must also be linked against the readline library: -lreadline -lbobcat The classes depending on the readline library can safely be left out of the bobcat library if you're not planning to construct programs using them. Press Enter y if you WANT to compile the classes using the readline library Press Enter or any other line if you DON'T WANT to include these classes in the bobcat library. y The class FBB::Milter can only be compiled if you have installed the file libmilter/mfapi.h. To use the class Milter, programs using Milter objects must also be linked against the milter library: -lmilter -lbobcat The class FBB::Milter can safely be left out of the bobcat library if you're not planning to construct mail filters using FBB::Milter. Press Enter y if you WANT to compile the files of the class FBB::Milter. Press Enter or any other line if you DON'T WANT to include the class FBB::Milter in the bobcat library. n <snip>
Installing

apprentice@testbox:~$ sudo ./build install

Procedure 23. Flexc++

Fetching

apprentice@testbox:~$ wget https://www.icce.rug.nl/debian/flexc++/flexc++_0.09.51.tar.gz apprentice@testbox:~$ tar zxf flexc++_0.09.51.tar.gz apprentice@testbox:~$ cd flexc++-0.09.51
Edit INSTALL.im
Make it install in /usr/local by setting that path in INSTALL.im:
<snip> void setLocations() { BASE = "/usr/local" <snip>
Build

apprentice@testbox:~$ ./build program
Install

apprentice@testbox:~$ sudo ./build install
