Hi,
I could solve the problem in the meantime. I've put "exit" at the end of the
script and I found out that calling g++ also with the linker flags was a
problem.
@Tyler:
With this script I've now solved the problem adding "-frandom-seed=<checksum>"
to gcc's argument list by bypassing the direct call of gcc and first calling my
script.
(See my question "How to calculate a value "on the fly" for use with
gcccompiler option?", Fr 17-Jul-2009)
The script looks like this now:
------------------------
#!/bin/bash
COMPILING=FALSE
# Get filename of current source file from list of arguments
for argument in $@ ;do
if [ "$COMPILING" = "TRUE" ]; then
FILENAME=$argument
fi
if [ "$argument" = "-c" ]; then
COMPILING=TRUE
fi
done
if [ "$COMPILING" = "TRUE" ]; then
# Calculate source file's checksum and add the argument
"-frandom-seed=<checksum>"
CHECKSUM=`md5sum $FILENAME | sed 's/\(.*\) .*/\1/'`
# Append the argument to the list of given arguments
args="$@ -frandom-seed=$CHECKSUM"
# Call compiler with modified argument list
/home/jf0068/ws/MCU_int/MCU/Tools/ELDK/usr/bin/ppc_82xx-gcc $args
else
# Call linker with unmodified argument list
/home/jf0068/ws/MCU_int/MCU/Tools/ELDK/usr/bin/ppc_82xx-gcc $@
fi
exit
------------------------
Cheers,
Joerg
