dev-img installed but g++ acting funny

[projekt]

Hi, I'm a musician who wants to learn c++ just as a side hobby. I am new to linux and don't know a whole lot. I am not illeterate when it comes to computers however. anyways, I want to get the devimg working. i have a 5500sl w/a 256 sandisk SD card. I have the image and the script on /mnt/card and also created /mnt/dev for my final destination. Here is what I typed....

# image_setup.sh /mnt/card/dev_img-1.5 /mnt/dev
Setting mount point /mnt/dev...
Mounting image /mnt/card/dev_img-1.5...
Can't find /home/system/var/mnt/dev in /etc/fstab
Failed to mount image /mnt/card/dev_img-1.5 on /mnt/dev

I also nano'd fstab and this is whats inside, don't really know what any of it means...

/dev/mtdblock0  /       cramfs  ro              1  1
/dev/ram1       /dev    minix   defaults        1  2
/dev/mtdblock1  /home   ext2    defaults        1  2
/dev/hda1       /mnt/cf auto    noauto,owner    0  0
/dev/mmcda1     /mnt/card       auto    noauto,owner    0  0
none            /dev/pts        devpts  gid=5,mode=620  0  0
/mnt/card/dev_img-1.5 /mnt/dev/ cramfs loop,noauto 0 0


I can see that on the last line is where the script added what I typed.  I am really confused here. I am a linux noob and a programming noob so this is just way over my head. I have however searched the forums and google quite extensively so I come to you defeated, not just looking for a quick ansewr. Thank you for your help.

You do not have to mount the image file to /mnt/dev.  You can mount it to /home/zaurus/develop.  I mentioned in one of my postings how I got it to work manually:

Devimg installed, but from what I know you just g++ x.cpp and it should work, right?

You are now set up for dev using /home/zaurus/develop
# g++
gcc: installation problem, cannot exec `/usr/lib/gcc-lib/armv4l-redhat-linux/2.95.1/collect2': Exec format error

Also, how can I see what loop devices are currently active? I noticed that after I ran this script, I came back and tried to go onto my SD card and I didn't see any files or folders anywhere under mnt! I need help here, this is driving me bonkers!

I've never received those error messages.  The "File exists" errors seem to indicate that you ran the compiler_setup.sh script more than once.  Did you execute the "su root" command to become the root user prior to executing the compiler_setup.sh script?

You can type the

mount

command by itself to see what devices are currently mounted.

Are you able to type the command:

cd /home/zaurus/develop
ls

and get a list of directories?

What happens when you run:

md5sum /home/zaurus/develop/lib/gcc-lib/armv4l-redhat-linux/2.95.1/collect2

Is the result different from when you run:

md5sum /usr/lib/gcc-lib/armv4l-redhat-linux/2.95.1/collect2

The md5 checksum that I get is 5c268f025b1861b850cdcbc1e7eb9098.

I learned today that a program called autoconf is hard-coded to look in "/mnt/dev/bin" for a file that is in "/home/zaurus/develop/bin".  That means that you have to do something like:

su root
cd /mnt
ln -s /home/zaurus/develop dev
exit

to link /mnt/dev to /home/zaurus/develop.
