Is the uClibc/uC-glibc platform dependent??
Can we use the "normal linux  glibc" instead of uClibc/uC-glibc when running
uClinux??
As to object file format, is it real necessary to modify the elf2flt
program?
On the other hand, there is an isssue which confuses me.
That is, i had already got a cross-compiler for compiling the "normal linux"
kernel used.
Should i need to remake a cross-compiler to compile the uClinux kernel and
applications?

Thanks.
