Hi Sir,
I am working on the jpeg image file encryption and decryption, for this downloaded the 
source code from  link :http://www.aescrypt.com/linux_aes_crypt.html  for linux .
I cross compiled this code package and for arm-none-linux-gnueabi-gcc   compiler.
But i am getting run time error "Error in iconv_open: Invalid argument" .
How this error i can solve and which library supports the UTF-16 in LINUX (ubuntu-10.10) please help me.
Processor : DM3730.
