This is enabled by default on platforms +other than MinGW and can be disabled by passing the --disable-open-zfile flag +to the configure script. + +--enable-stat-zfile make libXpm search for a file name with .Z or .gz added +if it can't find the file it was asked to open. It relies on the +--enable-open-zfile feature to open the file, and is enabled by default +when --enable-open-zfile is enabled, and can be disabled by passing the +--disable-stat-zfile flag to the configure script. diff --git a/configure.ac b/configure.ac index 789a96e..1b64830 100644 --- a/configure.ac +++ b/configure.ac @@ -49,25 +49,35 @@ if test "x$USE_GETTEXT" = "xyes" ; then fi AM_CONDITIONAL(USE_GETTEXT, test "x$USE_GETTEXT" = "xyes") +# Optional feature: When a filename ending in .Z or .gz is requested, +# open a pipe to a newly forked compress/uncompress/gzip/gunzip command to +# handle it. +AC_MSG_CHECKING([whether to handle compressed pixmaps]) +case $host_os in + *mingw*) zpipe_default="no" ;; + *) zpipe_default="yes" ;; +esac +AC_ARG_ENABLE(open-zfile, + AS_HELP_STRING([--enable-open-zfile], + [Search for files with .Z & .gz extensions automatically @<:@default=auto@:>@]), + [OPEN_ZFILE=$enableval], [OPEN_ZFILE=yes]) +AC_MSG_RESULT([$OPEN_ZFILE]) +if test x$OPEN_ZFILE = xno ; then + AC_DEFINE(NO_ZPIPE, 1, [Define to 1 to disable decompression via pipes]) +fi + # Optional feature: When ___.xpm is requested, also look for ___.xpm.Z & .gz # Replaces ZFILEDEF = -DSTAT_ZFILE in old Imakefile +AC_MSG_CHECKING([whether to search for compressed pixmaps]) AC_ARG_ENABLE(stat-zfile, - AS_HELP_STRING([--enable-stat-zfile], - [Search for files with .Z & .gz extensions automatically @<:@default=yes@:>@]), - [STAT_ZFILE=$enableval], [STAT_ZFILE=yes]) + AS_HELP_STRING([--enable-stat-zfile], + [Search for files with .Z & .gz extensions automatically @<:@default=auto@:>@]), + [STAT_ZFILE=$enableval], [STAT_ZFILE=$OPEN_ZFILE]) +AC_MSG_RESULT([$STAT_ZFILE]) if test x$STAT_ZFILE = xyes ; then - AC_DEFINE(STAT_ZFILE, 1, [Define to 1 to automatically look for files with .Z & .gz extensions]) + AC_DEFINE(STAT_ZFILE, 1, [Define to 1 to automatically look for files with .Z & .gz extensions]) fi - -case $host_os in - *mingw*) - AC_DEFINE(NO_ZPIPE, 1, [Define to 1 to disable decompression via pipes]) - ;; - *) - ;; -esac - AC_CONFIG_FILES([Makefile doc/Makefile include/Makefile |
