Date: Sun, 26 Feb 2006 11:25:09 +0900 From: Hayashi Naoyuki 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)) ^ cc: Error: ./src/video/x11/SDL_x11sym.h, line 150: In this statement, "_SmtBufferOverflow" is not declared. (undeclared) SDL_X11_SYM(1,void,_SmtBufferOverflow,(Display *dpy,register smtDisplayPtr)) ^ cc: Error: ./src/video/x11/SDL_x11sym.h, line 150: In this statement, "_SmtIpError" is not declared.
