CD files not executable

CD files not executable

Post by Pierre Jouber » Sun, 02 Jun 1996 04:00:00


After I mounted my CD's all the files on it is read only for examples
ls -l /cdrom gives:
-r--r--r--   1 root     root          188 Apr 13  1995 owssetup
dr-xr-xr-x   1 root     root         2048 Apr 18  1995 server

The file owssetup is executable but I can not run it because it is mounted
as read only . If have tried more than one cdrom and the files are always
read only.

If have also tried on Slackware with kernel 1.2.13, Redhat 3.0.3 and
redhat 3.0.3 with kernel 1.99.9 . I have tried an sounblaster kit as well
as an CDROM drive on /dev/hdb. The ISO9660 file system is in the kernels.

I use mount -t iso9660 -r /dev/hdb /cdrom or
      mount -t iso9660 -r /dev/sbpcd /cdrom

Can anybody help me please.


1. gdb: core file not in executable format: File format not recognized

We have been having problems recently getting a copy of gdb 4.17 to work
under solaris 2.4 on a sparc20.  Using gcc, which seems to compile
correctly, and copies of gdb both built from source and also a prebuilt
binary downloaded from, I am unable to read any core file.  
The message I always get is:

core: not in executable format: File format not recognized

I am beginning to think that the problem lies not with the build of gdb,
but more with the configuration of gcc.  Can anyone help me?  I have run
out of ideas about the cause of this.....
