From d97c090d07659128d425074d75d5aa3745ceb5e5 Mon Sep 17 00:00:00 2001 From: Sam Lantinga Date: Sun, 7 Mar 2004 16:40:15 +0000 Subject: [PATCH] Date: Sun, 07 Mar 2004 22:54:11 +0900 From: Hayashi Naoyuki Subject: Tru64 cdrom and pthread option fix SDL-1.2.7/src/cdrom/osf/SDL_syscdrom.c Fixes Some CD-ROM drives(ex. TEAC CD-532E) cannot play first 150 frames(aka gap). CheckDrive() fix. The end of comment is "* /" in AddDrive(). SDL-1.2.7/configure.in Fixes Add *-*-osf pthread option and delete line SDL_LIBS="$SDL_LIBS -lrt". --HG-- extra : convert_revision : svn%3Ac70aab31-4412-0410-b14c-859654838e24/trunk%40874 --- configure.in | 10 +++- src/cdrom/osf/SDL_syscdrom.c | 110 +++++++++++++++++------------------ 2 files changed, 63 insertions(+), 57 deletions(-) diff --git a/configure.in b/configure.in index 257ca0c8..6f4c9a73 100644 --- a/configure.in +++ b/configure.in @@ -1217,6 +1217,15 @@ CheckPTHREAD() pthread_cflags="" pthread_lib="" ;; + *-*-osf*) + if test x$ac_cv_prog_gcc = xyes; then + pthread_cflags="-D_REENTRANT" + pthread_lib="-lpthread -lrt" + else + pthread_cflags="-pthread" + pthread_lib="-lpthread -lrt" + fi + ;; *) pthread_cflags="-D_REENTRANT" pthread_lib="-lpthread" @@ -2268,7 +2277,6 @@ case "$target" in CheckOpenGL CheckPTHREAD CheckSIGACTION - SDL_LIBS="$SDL_LIBS -lrt" # Set up files for the audio library if test x$enable_audio = xyes; then CFLAGS="$CFLAGS -I/usr/include/mme -DMMEAUDIO_SUPPORT" diff --git a/src/cdrom/osf/SDL_syscdrom.c b/src/cdrom/osf/SDL_syscdrom.c index 4ee92c0c..1934f470 100644 --- a/src/cdrom/osf/SDL_syscdrom.c +++ b/src/cdrom/osf/SDL_syscdrom.c @@ -59,46 +59,45 @@ static int SDL_SYS_CDStop(SDL_CD *cdrom); static int SDL_SYS_CDEject(SDL_CD *cdrom); static void SDL_SYS_CDClose(SDL_CD *cdrom); -/* Some ioctl() errno values which occur when the tray is empty */ -#define ERRNO_TRAYEMPTY(errno) \ - ((errno == EIO) || (errno == ENOENT) || (errno == EINVAL)) - /* Check a drive to see if it is a CD-ROM */ /* Caution!!
