From 94b7db20bcb82efba04bf5c56fea3f545d547b12 Mon Sep 17 00:00:00 2001 From: wm4 Date: Sun, 29 Jul 2012 00:22:13 +0200 Subject: configure: remove pointless checks for yasm etc. mplayer doesn't use yasm, as or ranlib. They were only needed to build with internal libav, which is gone. Also, get rid of nm. nm was used to find out how external symbols are mangled. Replace this by a platform check in mangle.h. As far as I know, sane systems don't mangle symbols. Windows prefixes them with an underscore ("_symbol"). I don't know about OSX. --- configure | 167 +------------------------------------------------------------- 1 file changed, 1 insertion(+), 166 deletions(-) (limited to 'configure') diff --git a/configure b/configure index 542c6ba416..5638d07f7c 100755 --- a/configure +++ b/configure @@ -152,19 +152,6 @@ EOF compile_check $TMPC $@ } -yasm_check() { - echo >> "$TMPLOG" - cat "$TMPS" >> "$TMPLOG" - echo >> "$TMPLOG" - echo "$_yasm $YASMFLAGS -o $TMPEXE $TMPS $@" >> "$TMPLOG" - rm -f "$TMPEXE" - $_yasm $YASMFLAGS -o "$TMPEXE" "$TMPS" "$@" >> "$TMPLOG" 2>&1 - TMPRES="$?" - echo >> "$TMPLOG" - echo >> "$TMPLOG" - return "$TMPRES" -} - pkg_config_add() { unset IFS # shell should not be used for programming echo >> "$TMPLOG" @@ -445,12 +432,7 @@ Miscellaneous options: --enable-runtime-cpudetection enable runtime CPU detection [disable] --enable-cross-compile enable cross-compilation [disable] --cc=COMPILER C compiler to build MPlayer [gcc] - --as=ASSEMBLER assembler to build MPlayer [as] - --nm=NM nm tool to build MPlayer [nm] - --yasm=YASM Yasm assembler to build MPlayer [yasm] - --ar=AR librarian to build MPlayer [ar] --pkg-config=PKGCONFIG pkg-config to find some libraries [pkg-config] - --ranlib=RANLIB ranlib to build MPlayer [ranlib] --windres=WINDRES windres to build MPlayer [windres] --target=PLATFORM target platform (i386-linux, arm-linux, etc) --enable-static build a statically linked binary @@ -518,14 +500,9 @@ _iwmmxt=auto _altivec=auto _install=install _pkg_config=auto -_ranlib=auto _windres=auto _cc=auto -_ar=auto test "$CC" && _cc="$CC" -_as=auto -_nm=auto -_yasm=auto _runtime_cpudetection=no _cross_compile=no _prefix="/usr/local" @@ -721,24 +698,9 @@ for ac_option do --cc=*) _cc=$(echo $ac_option | cut -d '=' -f 2) ;;
