The linker automagically extracts exactly the object files from the
archive it needs - nothing less, nothing more !
If you do
gcc -c rtprocess.c -o rtprocess_tmp.o
ld -r rtprocess_tmp.o -o rtprocess.o -lgcc
insmod rtprocess.o
you get exactly what you want - esp. rtprocess.o contains all parts from
libgcc it needs, but not the whole libgcc !
Are you sure you wanna do kernel programming without reading an
introduction to programming first ?
Probably you check out the compiler/linker manuals at least :-)
