hi,
I have built the newlib in the directory /usr/local/mips-mips-elf/lib
but when i want to link a program(The "Hello World") with the newlib,I
met a problem.
if I do:
mips-mips-elf-gcc -o hello hello.c
the error message is :
/usr/local/mips-mips-elf/lib/crt0.o: In function `zerobss':
../../../../../gcc-2.95.3/libgloss/mips/crt0.S:132: undefined reference to
`get_mem_info'

if i do this way:
mips-mips-elf-gcc -c hello.c -o hello.o
mips-mips-elf-gcc -L/usr/local/mips-mips-elf/lib -lc
-I/usr/local/mips-mips-elf/include hello.o
/usr/local/mips-mips-elf/lib/crt0.o -o hello
the error message is :
