world/bullet.hpp:23: error: type specifier omitted for parameter `szBullet'

To me this looks like it is not finding the Sint32 type in SDL_types.h? Either that or it is not finding my util/graph.h?

But hey, on the positive side, main.cpp and config.cpp have successfully compiled!  :>

Compiling craftselect.cpp... here's the full first error:

In file included from world/weapon.hpp:8,
                 from world/craft.hpp:11,
                 from craftselect.hpp:9,
                 from craftselect.cpp:5:
world/bullet.hpp:23: error: type specifier omitted for parameter `szBullet'
world/bullet.hpp: In member function `TeRect TeBullet::getBoundRect()':
world/bullet.hpp:236: error: request for member `CenteredAt' in `rclBullet',
   which is of non-aggregate type `const TeRect ()(TePoint (*)())'

"non-aggregate" apparently means the compiler doesn't think the return value from CenteredAt is a class or struct. It looks fine to me:

TeRect CenteredAt( TePoint pt ) const;

Lemme sleep on it, I'll give you an answer in the morning...

I emailed you the entire makefile generated by Dev-Cpp.

Here is the portion that applies to craftselect.cpp:

I'm thinking it's a [const] issue... checking...

On the side, there is a new Windows demo available at http://soloforge.com/files/TerminusDemo.zip

Dang John! The content is BURSTING FORTH! This is fun stuff... like a graphic novel come to life...

Cool :-) Oh, the fighter melee tutorial is broken. The latest SVN version fixes it.

Trying to isolate the error in bullet.hpp...

cd terminus/terminus/world
cp bullet.hpp test.cpp
g++ -I/home/m/development/terminus/fmod/api -I/usr/include/SDL test.cpp

That does it. Now to play with test.cpp... OK, looks like g++ sees these and thinks they are function declarations:

const TeSize szBullet( nBulletW, nBulletH );
const TeRect rclBullet( TePoint(), szBullet );

Change to this and g++ "gets" it:

const TeSize szBullet = TeSize( nBulletW, nBulletH );
const TeRect rclBullet = TeRect( TePoint(), szBullet );

John, I hope you don't mind, I checked in that change, and one other similar change in world/craft.hpp. I want to be EXTREMELY careful about breaking anything of yours, can you see if it still works for you?

I suppose to do this right, I should have both Linux and Windows builds set up and test in both... eventually... :>

Next up: replace _finddata_t in the Linux build with a Linux equivalent...

profile.cpp:6:16: io.h: No such file or directory
profile.cpp: In member function `void
   TeProfileMgr::Load(std::basic_string<char, std::char_traits<char>,
   std::allocator<char> >)':
profile.cpp:449: error: `_finddata_t' undeclared (first use this function)

I found some suggestions:

Try looking at the following functions
opendir
readdir, readdir_r
fnmatch[/color]
scandir, where available
take a look at glob(3c) and ftw/nftw

I have two options:

1. Make my own reusable functions for file operations
2. Use the filesystem library in boost.

The first is better if the job is small, but little guys can't afford to reinvent the wheel for anything substantial. I already use boost in HTDJ for serialization. It's definitely got a ramp up time, but it's not too heavy once you're up to speed. I will explore the boost filesystem library docs next...
