Compiling the SDL version in Windows

[jamespetts]

How does one compile the SDL version of Simutrans under Windows?

[vilvoh]

Perhaps with cygwin? It's a Linux-like environment for Windows that makes possible to port software running on POSIX systems (such as Linux, BSD, and Unix systems) to Windows.

[jamespetts]

How would I go about setting that up?

[VS]

You could probably dive into depths of mingw and makefiles and all that nastiness. IIRC prissi uses cygwin+mingw... but better wait for someone [other than me] who knows what he talks about.

[prissi]

Mingw or MSVC++. Have a look at the official SDL-pages, they have a version for MSVC too ... You need then include SDL_sound and simsys_s.cc. (I haven't tried this with MSVC but i should work ... )

[jamespetts]

Ahh, I have tried with MSVC++, and it doesn't work - I get the following errors:

1>simsys_s.cc
1>.\simsys_s.cc(678) : error C2664: 'MessageBoxW' : cannot convert parameter 2 from 'const char *' to 'LPCWSTR'
1>        Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
1>.\simsys_s.cc(682) : error C2664: 'MessageBoxW' : cannot convert parameter 2 from 'const char *' to 'LPCWSTR'
1>        Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast


Any idea how to resolve them?

[prissi]

Cast them or switch off error 2664. Or better use MessageBoxA, since the strings will be ASCII anyway ...

[jamespetts]

Prissi,

thank you very much. I switched to MessageBoxA, but then got this error:

1>simsys_s.obj : error LNK2019: unresolved external symbol _dr_screenshot_png referenced in function "int __cdecl dr_screenshot(char const *)" (?dr_screenshot@@YAHPBD@Z)
1>Debug (SDL)\Simutrans-Experimental-SDL.exe : fatal error LNK1120: 1 unresolved externals


Any ideas?

[prissi]

add also dr_scr4eenshot_w32.c to your makefile?

[jamespetts]

Prissi,

sorry if this is a silly question - but where would I find dr_scr4eenshot_w32.c?

[VS]

James, the file is called simsys_w32_png.c and I was able to locate it after some rather rudimentary searches. Although, the difference might be that I knew from previous rummaging through code that the libraries' bindings are mostly in simsys_*files.

[jamespetts]

VS,

that can't be right: that file is already included in the project, and it is a GDI file. The very top has the following code:

Code Select Expand


#ifndef WIN32
#error "Only Windows has GDI+!"
#endif

// windows Bibliotheken DirectDraw 5.x
#include <windows.h>


[VS]

Still, it is the file containing implementation of dr_screenshot_png. I don't see anything else in it, so it might be safe to assume it's what you need and - just go ahead and try...? Although there might be some problem with leading underscore? It (the first _) isn't anywhere in my version of sources.

FWIW, saving as png can be done by linking to either libpng, or any other library (capable of that feat), which is in this case gdi+. So it's just for saving the picture, not as the whole backend. Or at least it seems so to me.

[jamespetts]

VS,

ahh, you were right: enabling that did let it compile. It was somewhat confusing - I thought that it was a GDI implementation. However, now, I have another problem: as soon as it starts, it immediately exits again, with a code of -1:

Any ideas what this problem might be?

[VS]

Sorry, not at all.

[prissi]

Wrong SDL version?

[jamespetts]

Which version should I have? I downloaded the latest...
