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)

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: .PP .nf \f(CW\&. \&. while(SDL_PollEvent(&event)){ switch(event\&.type){ case SDL_KEYDOWN: if(event\&.key\&.keysym\&.sym==SDLK_LEFT) move_left(); break; \&. \&. \&. } } \&. \&.\fR .fi .PP \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: .PP .nf \f(CWchar ch; if ( (keysym\&.unicode & 0xFF80) == 0 ) { ch = keysym\&.unicode & 0x7F; } else { printf("An International Character\&. "); }\fR .fi .PP UNICODE translation does have a slight overhead so don\&'t enable it unless its needed\&. .SH "SEE ALSO" .PP \fI\fBSDLKey\fR\fR ...\" created by instant / docbook-to-man, Tue 11 Sep 2001, 23:00
