Problem in installing JPEG Viewer on DM355

Perhaps this might help, this is the boot log I get, I just noticed the line 'Read Only File System' . :

sounds like a permission problem.  I believe the entire target file system should have root permission if you follow the Getting Started Guide....

I have followed all the instructions. In the exportfs file, I have set the file system to rw permission. Could any other thing have caused this problem .

I found a forum where someone suggested that changing the etc\fstab file might help. There, the default statement is 'error remount-ro' .  I thought this might have been a problem so I set it to 'error continue' but even that didn't help.

So I'm still stuck [:(]

Hi

I successfully solved the permissions problem. Installed the libexif as per instructions.

But there is a problem with fbida. If I run make, I get the following error:

  LD      exiftran

/usr/lib/gcc/armv5tl-montavista-linuxeabi/3.4.3/../../../../armv5tl-montavista-linuxeabi/bin/ld: skipping incompatible /usr/local/lib/libexif.so when searchf

/usr/lib/gcc/armv5tl-montavista-linuxeabi/3.4.3/../../../../armv5tl-montavista-linuxeabi/bin/ld: cannot find -lexif

collect2: ld returned 1 exit status
make: *** [exiftran] Error 1

(The last words of error are not visible because of screen size.)

I had set /etc/ld.so.cofig file to the directory of libexif installation , i.e. : /usr/local/lib  and run ldconfig. I also checked that the files were actually present in the folder.

What can the problem be ?

Problem solved !

It was a version problem , downloaded the correct libexif version

I successfuly installed the jpeg viewer. and updated the ld.so.conf file.

However I get the following error while running fbi:

fbi: error while loading shared libraries : libexif.so.12 : cannot open shared object file: No such file or directory

Is it because I skipped the part : 'Setting up your virtual terminal' ? Is it mandatory. I tried following the steps that were mentioned but there was some kind of error

I also found that dm355 comes with an inbuilt jpeg demo. How do i install the jpegdec on the board. ? Running $ make clean and $ make on the host in jpegdec directory gives an error. (something like no such file or directory) Is there something that needs to be done before this?

I am unable to post log now , but will do so if you want it.

Thanks a lot
