Fixed bug #895 Markus Rothe 2009-12-07 09:32:46 PST Check if libspe2 is available Building on PowerPC64 results in: [...] In file included from ./src/video/ps3/SDL_ps3events_c.h:33, from ./src/video/ps3/SDL_ps3video.c:32: ./src/video/ps3/SDL_ps3video.h:34:21: error: libspe2.h: No such file or directory In file included from ./src/video/ps3/SDL_ps3events_c.h:33, from ./src/video/ps3/SDL_ps3video.c:32: ./src/video/ps3/SDL_ps3video.h:75: error: expected specifier-qualifier-list before 'spe_context_ptr_t' ./src/video/ps3/SDL_ps3video.c:78: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'fb_writer_spu' ./src/video/ps3/SDL_ps3video.c: In function 'PS3_VideoInit': ./src/video/ps3/SDL_ps3video.c:167: error: 'spu_data_t' has no member named 'program' ./src/video/ps3/SDL_ps3video.c:167: error: 'fb_writer_spu' undeclared (first use in this function) [...] The problem is that the ps3 video driver is being build regardless if libspe2 is installed or not. The attached patch fixes this problem. [ Note: The other headers that are being checked for are coming from the linux headers package on powerpc64. As a result these are also available if you're on a generic powerpc64 machine and not a PS3 only. ]

.SH "NAME"
SDL_JoystickGetAxis \- Get the current state of an axis
.SH "SYNOPSIS"
.PP
\fB#include "SDL\&.h"
.sp
\fBSint16 \fBSDL_JoystickGetAxis\fP\fR(\fBSDL_Joystick *joystick, int axis\fR);
.SH "DESCRIPTION"
.PP
\fBSDL_JoystickGetAxis\fP returns the current state of the given \fBaxis\fR on the given \fBjoystick\fR\&.
.PP
On most modern joysticks the X axis is usually represented by \fBaxis\fR 0 and the Y axis by \fBaxis\fR 1\&. The value returned by \fBSDL_JoystickGetAxis\fP is a signed integer (-32768 to 32768) representing the current position of the \fBaxis\fR, it maybe necessary to impose certain tolerances on these values to account for jitter\&. It is worth noting that some joysticks use axes 2 and 3 for extra buttons\&.
.SH "RETURN VALUE"
.PP
Returns a 16-bit signed integer representing the current position of the \fBaxis\fR\&.
