How to make kernel-less monolithic executables

[Altera_Forum]

Hello, 

 I would like to run a small socket-based communication program on a Nios II processor. This program calls some uClinux functions: socket(), setsocketopt(), connect(), bind(), send(), and recv().   Is it possible to link these modules into a signle kernel-less executable (a standalone executable without the kernel) ?  I would like to find a way to reduce the size of the executables.  Any information would be appreciated.  Sekiyama

Hi sekiyama, 

 If the size of the executable is your major concern, you can check lwIP with MicroC/OS II to see if it meets your requirements. As I know, lwIP has a BSD socket like API, similar to what you get from uClinux. And I am sure the application can be very small.  Regards, wentao
