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)
