[imp-dev] Re: LPG on Linux for X86_64 architectures

["Robert M. Fuhrer" <rfuhrer@xxxxxxxxxxxxxx>]

Hi Jurgen,

We don't intend to discontinue the 32-bit releases, but at the moment  
I don't have access to a 32-bit machine (at least not that I know of).

So, if someone out there has a 32-bit Linux box and would like to  
build the latest LPG for that platform, now would be a great time to  
speak up. :-)

The build is trivial:

 % cvs -d :pserver:anonymous@xxxxxxxxxxxxxxxxxxxxxxx:/cvsroot/lpg co  
lpg.generator.cpp
 % cd src
 % export ARCH=linux_x86
 % make

You'll find the binary named lpg-linux_x86 in both the "src" and "bin"  
directories.
