Croce compilazione Direct3D su Linux con mingw

Domanda
Come configurare mingw32 di cross-compilazione Direct3D applicazioni per Windows? C'è qualche possibilità? Ho effettivamente riuscito codice di compilazione da questo tutorial: http://www.directxtutorial.com /Tutorial9/B-Direct3DBasics/dx9B4.aspx - con Code :: Blocks su Kubuntu con i586-mingw32msvc-g ++. Avevo bisogno di aggiungere #define UNICODE
e rimuovere le parti #pragma ...
per fare questo, e ho usato i file di intestazione da / usr / i586-mingw32msvc / includere e librerie anche dal pacchetto MinGW.
Comunque posso codice non compilazione da questo tutorial: http: //www.directxtutorial .com / Tutorial9 / B-Direct3DBasics / dx9B5.aspx
Mingw non ha il file d3dx9.h
. Così ho installato il pacchetto wine1.2-dev
con le versioni del vino di file di intestazione di Windows-correlate, ma ora ho errori:
Con #define UNICODE

Devo installare attraverso il vino MS DirectX SDK? Cambiare qualcosa con il codice? Sono DirectX e Windows-correlati cose Noob ma voglio solo per attraversare-compilare alcuni semplici esempi di D3D e verificare se funziona.
Soluzione
Ok! Ho finalmente riuscito!
Purtroppo, avevo bisogno di scaricare Microsoft DirectX SDK (aprile 2007) (non ho potuto installare quelli più recenti con il vino).
Poi ho dovuto installare MinGW con vino e anche installare MinGW-utils 0.3 (ho dovuto ottenere il file di reimp.exe).
Poi ho creato PATH nel registro di vino per C:\windows;C:\windows\system;C:\MinGW\bin
Poi ho fatto wine reimp.exe "C:\Program Files\Microsoft DirectX SDK (April 2007)/Lib/x86/d3dx9.lib"
. Questo file d3dx9_33.a
comando generato, ho cambiato a d3dx9.a
e lo mise in /usr/i586-mingw32msvc/lib/
.
Inoltre ho copiato tutti i file header che mancano dal DirectX SDK per /usr/i586-mingw32msvc/include
.
E poi ... ho compilato il programma, collegandola alla libd3d9.a e libd3dx9.a, e compilato, collegato, e funziona!
Quindi la buona notizia è:. Si può compilare i programmi di Windows DirectX sotto Linux utilizzando versione Linux di MinGW
La cattiva notizia:. Una necessità di installare alcuni programmi di utilità MinGW e tutta la MS DX SDK utilizzando vino
Modifica
E ancora una cosa: avevo bisogno di fare tutto WCHAR * getti -related manualmente - grida MinGW con errori se non è fatto. Goz era disponibile qui.
Altri suggerimenti
Se si modificano le stringhe
(const WCHAR*)L"blah blah"
Poi si deve compilare la sua non è l'ideale, ma sembra che wchar_t e WCHAR non sono compatibili con MinGW. Non sono del tutto sicuro perché non si compila anche se, come windows.h definisce WCHAR come un typedef di wchar_t ...
È anche possibile la cross-compilazione mingw pianura per esempio Debian o Ubuntu, e il codice per DirectX solo con LoadLibrary () e GetProcAddress (). (Ma i tutorial su DirectX non possono essere utilizzati come-è quindi.)
