Thanks for the replies guys.
Martin:
The Gog files are indeed Windows .exe's but unfortunately no luck running them successfully under Odin. And as Dave mentions, Innoextract doesn't work any better under Odin.
Dave:
From what I've read, most of the Boost libraries are just headers only, however, as luck would have it the 5 specific libraries needed to build Innoextract, are not. They include iostreams, filesystem, date_time, system and program_options. Although system is just a stub library provided for compatibility so it's actually header only now.
I'm still reading and researching on porting this. I'm going to see how far I can get. Hopefully it will end with success. Again, thoughts, opinions, etc. are always welcome.
Thanks,
Tony.
