Re: Executing a shell script in a Makefile

[G2345C]

Hi, Here is the copyfile.sh script, there is no
background copy, I think.

if [ -r $GPS_ENGINE_MANIFEST_FILE ]; then
   while read LINE
   do
      OBJ_TO_COPY=""
      OBJ_LIBS_TO_COPY=""
      OROOT=`echo $LINE | awk -F":" '{print $1}'`
      OPATH=`echo $LINE | awk -F":" '{print $2}'`
      if [ "$OROOT" = "SLS_ROOT" ]; then
         OBJS_BASE_DIR=`dirname ${OPATH}`
         OBJS_BASE_NAME=`basename ${OPATH}`
         OBJ_TO_COPY="$SLS_ROOT/${OPATH}.lo
$SLS_ROOT/${OPATH}.o"
        
OBJ_LIBS_TO_COPY="$SLS_ROOT/${OBJS_BASE_DIR}/.libs/${OBJS_BASE_NAME}.o"
         cp -p $OBJ_TO_COPY $GPS_ENGINE_OBJS_DIR
         cp -p $OBJ_LIBS_TO_COPY
$GPS_ENGINE_OBJS_DIR/.libs
      fi
      if [ "$OROOT" = "COMMON_ROOT" ]; then
         OBJS_BASE_DIR=`dirname ${OPATH}`
         OBJS_BASE_NAME=`basename ${OPATH}`
         OBJ_TO_COPY="$COMMON_ROOT/${OPATH}.lo
$COMMON_ROOT/${OPATH}.o"
        
OBJ_LIBS_TO_COPY="$COMMON_ROOT/${OBJS_BASE_DIR}/.libs/${OBJS_BASE_NAME}.o"
         cp -p $OBJ_TO_COPY $GPS_ENGINE_OBJS_DIR
         cp -p $OBJ_LIBS_TO_COPY
$GPS_ENGINE_OBJS_DIR/.libs
      fi
   done < $GPS_ENGINE_MANIFEST_FILE
fi
