I am trying to execute certain fileutils application like cp ,ls .. These applications are compiled using the Glibc 2.2.3 The problem is if i compile the applications Statically and try to execute the command cp,ls ..i get the segmentation fault error.Please let me know the proper compiler options for static linking.
Please explain which toolchain you are yusing, which libraries, and which versions of the tools listed above.
OBJS = cat.o chgrp.o chmod.o chown.o cmp.o cp.o dd.o
grep.o l.o ln.o ls.o \
mkdir.o mkfifo.o mknod.o more.o mv.o rm.o
rmdir.o sync.o touch.o vi.oWhere did you get these object files from? I have a suspicion that these are in fact parets of the busybox toolbox. If this is correct, then why don't you simply use the Makefile that comes with busybox?
Then i tried to eliminate the problem by using shared library that is put the ld.so.1 file and libc.so.6 file in the /lib directory of the ramdisk . The problem is the library files are too big in size. libc is 5.1mb and ld.so.1 is .5mb
You can strip the shared libraries for the target.
inorder to create a ramdisk image i have used the
initrd.sudo scrip file form the denx SELF package.
: ${IRD_SIZE:=4096k}
dd if=/dev/zero of=$IMAGE bs=$IRD_SIZE count=1
2>/dev/nullAgain, I have the suspicion that this code comes from our SELF package. The scripts provided by SELF take care of all the problems you are running in.
1.should i use statick linking
No, this will most probably just increasy your memory footprint.
2.shared library ..
Yes. What I don't understand: there is a working set of tools and scripts. You rip it apart, omit essential parts, and then complain that it is not working any more. What else did you expect?
