Hello,

I am trying to make this compile and run on freebsd. Here is my patch so far:

[/code]

This builds for me, provided I put -march=i486 in CPPFLAGS, as the default arch for gcc in freebsd is i386, and then it would fail at StdSync.h with an undefined reference to __sync_add_and_fetch_4.

I've blocked out the backtrace, as I think that would have to have freebsd specific code, and I am not sure how that would be done. And I moved a bunch of includes in C4NetIO.h because that file needed netinet/in.h and it wasn't included soon enough. Then I think the apostrophe at the end of   #define C4_OS "unknown"; was causing problems for any other OS than the 3 listed.

It compiled and starts up, but then I have other problems. When I start, it asks for a new player, but then when I put one in it says "open: file not found". And it doesn't seem to save any changes I make in options. So I think it is having path issues. There is no graphic when it starts up, or behind the menu, but maybe there just isn't any yet?

Then when I click 'start game', it starts loading the list of missions, but then seems to hang. A few seconds later it aborts and I get this message in the console:

terminate called after throwing an instance of 'std::runtime_error'
  what():  DirectoryIterator::Read(const char*): Unable to read file system
Abort (core dumped)

Any ideas why?

I havn't yet tried 'make install' - but I would rather get this to work in a user directory first.
