三：以上Festival安装完成以后回到ekho安装目录：

执行./configure --enable-festival 前

更改configure

1：替换

#AC_DEFINE(ENABLE_FESTIVAL,,[Enable Festival])

#LIB_FESTIVAL="${srcdir}/lib/libFestival.a ${srcdir}/lib/libestools.a ${srcdir}/lib/libestbase.a ${srcdir}/lib/libeststring.a -lncurses"

#           CFLAG_FESTIVAL="-I${srcdir}/include/festival -I${srcdir}/include/speech_tools"

else

  { { $as_echo "$as_me:${as_lineno-$LINENO}: error: in \`$ac_pwd‘:" >&5

$as_echo "$as_me: error: in \`$ac_pwd‘:" >&2;}

as_fn_error $? "ncurses test failed

See \`config.log‘ for more details" "$LINENO" 5; }

fi

          { $as_echo "$as_me:${as_lineno-$LINENO}: checking for main in -lestools" >&5

$as_echo_n "checking for main in -lestools... " >&6; }

if ${ac_cv_lib_estools_main+:} false; then :

  $as_echo_n "(cached) " >&6

else

  ac_check_lib_save_LIBS=$LIBS

LIBS="-lestools

           $LIBS"

cat confdefs.h - <<_ACEOF >conftest.$ac_ext

/* end confdefs.h.  */

int

main ()

{

return main ();

  ;

  return 0;

}

_ACEOF

if ac_fn_c_try_link "$LINENO"; then :

  ac_cv_lib_estools_main=yes

else

  ac_cv_lib_estools_main=no

fi

rm -f core conftest.err conftest.$ac_objext \

    conftest$ac_exeext conftest.$ac_ext

LIBS=$ac_check_lib_save_LIBS

fi

{ $as_echo "$as_me:${as_lineno-$LINENO}: result: $ac_cv_lib_estools_main" >&5

$as_echo "$ac_cv_lib_estools_main" >&6; }

if test "x$ac_cv_lib_estools_main" = xyes; then :

  cat >>confdefs.h <<_ACEOF

#define HAVE_LIBESTOOLS 1

_ACEOF

  LIBS="-lestools $LIBS"

改为：

$as_echo "#define ENABLE_FESTIVAL /**/" >>confdefs.h

           LIB_FESTIVAL="${srcdir}/lib/libFestival.a ${srcdir}/lib/libestools.a ${srcdir}/lib/libestbase.a ${srcdir}/lib/libeststring.a -lncurses"

           CFLAG_FESTIVAL="-I${srcdir}/include/festival -I${srcdir}/include/speech_tools"

2：替换

as_fn_error $? "estool test failed

See \`config.log‘ for more details" "$LINENO" 5; }

fi

          { $as_echo "$as_me:${as_lineno-$LINENO}: checking for main in -lFestival" >&5

$as_echo_n "checking for main in -lFestival... " >&6; }

if ${ac_cv_lib_Festival_main+:} false; then :

  $as_echo_n "(cached) " >&6

else

  ac_check_lib_save_LIBS=$LIBS

LIBS="-lFestival

           $LIBS"

cat confdefs.h - <<_ACEOF >conftest.$ac_ext

/* end confdefs.h.  */

int

main ()

{

return main ();

  ;

  return 0;

}

_ACEOF

if ac_fn_c_try_link "$LINENO"; then :

  ac_cv_lib_Festival_main=yes

else

  ac_cv_lib_Festival_main=no

改为：

as_fn_error "ncurses test failed (--disable-festival to disable)

See \`config.log‘ for more details." "$LINENO" 5; }

3去掉：

rm -f core conftest.err conftest.$ac_objext \

    conftest$ac_exeext conftest.$ac_ext

LIBS=$ac_check_lib_save_LIBS

fi

{ $as_echo "$as_me:${as_lineno-$LINENO}: result: $ac_cv_lib_Festival_main" >&5

$as_echo "$ac_cv_lib_Festival_main" >&6; }

if test "x$ac_cv_lib_Festival_main" = xyes; then :

$as_echo "#define ENABLE_FESTIVAL /**/" >>confdefs.h

              LIB_FESTIVAL="-lFestival -lestbase -lestools -leststring -lncurses"

              CFLAG_FESTIVAL="-I/usr/include/festival -I/usr/include/speech_tools"

else

$as_echo "#define ENABLE_FESTIVAL /**/" >>confdefs.h

              LIB_FESTIVAL="${srcdir}/lib/libFestival.a ${srcdir}/lib/libestools.a ${srcdir}/lib/libestbase.a ${srcdir}/lib/libeststring.a -lncurses"

              CFLAG_FESTIVAL="-I${srcdir}/include -I${srcdir}/include/festival -I${srcdir}/include/speech_tools"

else

  LIB_FESTIVAL=""

         CFLAG_FESTIVAL=""

Fi

4：添加：

else

  with_mp3lame=no

fi

后添加

LIBS="-lasound $LIBS"

5以上更改以后：

在ekho安装目录下：

执行make

出现以下错误：

src/libekho.cpp:58:31: 错误：festival/festival.h：没有那个文件或目录

make[1]: *** [src/libekho_a-libekho.o] 错误 1

make[1]: Leaving directory `/home/new_uucc_soft/ekho-6.0‘

make: *** [all] 错误 2

解决方法：

用命令：mkdir /usr/include/festival

        cd /usr/include/festival

拷贝festival.h  fngram.h  intonation.h  lexicon.h  Makefile  ModuleDescription.h  modules.h  module_support.h  Phone.h  text.h

到festival文件夹下

6.回到ekho安装目录下：

执行make：

出现：

g++: ./lib/libFestival.a: No such file or directory

g++: ./lib/libestools.a: No such file or directory

g++: ./lib/libestbase.a: No such file or directory

g++: ./lib/libeststring.a: No such file or directory

make[1]: *** [test_ekho] 错误 1

解决办法：

在ekho安装目录下执行：

cp lib32  lib

在festival和speech_tools的安装目录下面将.a文件

/festival/src/lib/中的libFestival.a拷贝到ekho安装目录下的lib中并覆盖

/speech_tools/lib/中的libestools.a libestbase.a libeststring.a拷贝到ekho安装目录下的lib中并覆盖

最后，执行make && make install ，安装完成
