Subject: Re: [SDL] CVS stable again, please update SDL ports
Some problems are caused on Tru64 UNIX.
If applying SDL12-osf1.path, these problems are fixed.
1. configure-script say "recursive mutexes... no" and "pthread
semaphores... no".
checking for pthreads... yes
checking for recursive mutexes... no
checking for pthread semaphores... no
This is because it compiled without pthread_cflags and pthread_lib when
checking recursive mutexes and pthread semaphores.
2. Compiling src/audio/mme/SDL_mmeaudio.c fails.
cc: Severe: ./src/audio/mme/SDL_mmeaudio.c, line 25: Cannot find file
<mme_api.h> specified in #include directive. (noinclfilef)
#include <mme_api.h>
-^
This is because BUILD_CFLAGS is wrong.
3. Compiling src/cdrom/osf/SDL_syscdrom.c fails.
cc: Warning: ./src/cdrom/osf/SDL_syscdrom.c, line 176: Too few actual
parameters in the invocation of the macro "SDL_stack_alloc". (toofewactuals)
cdpath = SDL_stack_alloc(len);
------------------------------------^
cc: Error: ./src/cdrom/osf/SDL_syscdrom.c, line 176: Invalid expression.
(badexpr)
cdpath = SDL_stack_alloc(len);
-----------------^
SDL_stack_alloc is defined in include/SDL_stdinc.h.
#define SDL_stack_alloc(type, count) (type*)alloca(sizeof(type)*count)
4. Linking fails if running configure with --enable-x11-shared=yes.
/usr/ccs/bin/ld:
Warning: Unresolved:
p_XData32
5. Compiling src/video/x11/SDL_x11dyn.c fails if running configure with
--enable-x11-shared=no.
cc: Error: ./src/video/x11/SDL_x11sym.h, line 149: In this statement,
"_SmtBufferOverflow" is not declared. (undeclared)
SDL_X11_SYM(1,void,_SmtBufferOverflow,(Display *dpy,register smtDisplayPtr))

| 30 The \fBSDL_keysym\fR structure is used by reporting key presses and releases since it is a part of the \fI\fBSDL_KeyboardEvent\fR\fR\&. | |
| 31 .PP | |
| 32 The \fBscancode\fR field should generally be left alone, it is the hardware dependent scancode returned by the keyboard\&. The \fBsym\fR field is extremely useful\&. It is the SDL-defined value of the key (see \fISDL Key Syms\fR\&. This field is very useful when you are checking for certain key presses, like so: | |
| 33 .PP | |
| 34 .nf | |
| 35 \f(CW\&. | |
| 36 \&. | |
| 37 while(SDL_PollEvent(&event)){ | |
| 38 switch(event\&.type){ | |
| 39 case SDL_KEYDOWN: | |
| 40 if(event\&.key\&.keysym\&.sym==SDLK_LEFT) | |
| 41 move_left(); | |

| 46 } | |
| 47 } | |
| 48 \&. | |
| 49 \&.\fR | |
| 50 .fi | |
| 51 .PP | |
| 52 \fBmod\fR stores the current state of the keyboard modifiers as explained in \fI\fBSDL_GetModState\fP\fR\&. The \fBunicode\fR is only used when UNICODE translation is enabled with \fI\fBSDL_EnableUNICODE\fP\fR\&. If \fBunicode\fR is non-zero then this a the UNICODE character corresponding to the keypress\&. If the high 9 bits of the character are 0, then this maps to the equivalent ASCII character: | |
| 53 .PP | |
| 54 .nf | |
| 55 \f(CWchar ch; | |
| 56 if ( (keysym\&.unicode & 0xFF80) == 0 ) { | |
| 57 ch = keysym\&.unicode & 0x7F; | |
| 58 } | |
| 59 else { | |
| 60 printf("An International Character\&. | |
| 61 "); | |
| 62 }\fR | |
| 63 .fi | |
| 64 .PP | |
| 65 UNICODE translation does have a slight overhead so don\&'t enable it unless its needed\&. | |
| 66 .SH "SEE ALSO" | |
| 67 .PP | |
| 68 \fI\fBSDLKey\fR\fR | |
