Hello Franco, the selection between libc or uclibc is a major one in the SDK. These are the main "C" libraries and applications have to be compiled according to the kernel compilation. Infact the choose of gnu libc or gnu uclibc has to be made in the first steps of the SDK configuration, when you invoke "make menuconfig" The main selections for the SDK at the beginning of this configuration are: kind of board: LX816, LX832 etc. kind of kernel: 2.4.31 or 2.6.15 kind of "C" library: libc or uclibc
If you have a Fox equipped with a SDK set with libc you cannot compile applications asking to be compiled versus uclibc and viceversa. The reason of the existance of uclibc is mainly for size. uclibc is much smaller than libc but not so complete as the latter. For a certain amount of time old Foxboard have been factory programmed using uclibc to have more FLASH space for applications and sometimes users do so to have the possibility to fit more data and application code inside the Fox (even if now, with the new Foxes with 8MB of FLASH this is not anymore a real issue). Right now the standard SDK and factory programmed fimage for the Fox are compuiled against libc so you have to compile your applications against libc as well (so issuing in your application directory the command "make cris-axis-linux-gnu" before compiling your application. I have seen now the reason of the problem since in the article 711 "Compile a C application" we refer uclibc as the standard for kernel 2.6.x. This has been in the past as above explained but not anymore. I have corrected the putdated information and I apologize for any inconvenience we have generated . Thank you for raising this problem so that we could have corrected the article info. i hope you have not lost too much time on this and feel free to contatc us for any issue .
