LDFLAGS/CFLAGS

Vreau sa mentionez de la inceput ca sunt cam paralel cu linuxul.
Problema e urmatoarea: incerc sa compilez un program. In fisierul Makefile am urmatoarele:
CC=gcc
FC=g77
LDFLAGS= -lz -llapack -lf77blas -lcblas -latlas
CFLAGS=  -Dfull

Normal ca imi da eroare la compilare
/usr/bin/ld: skipping incompatible /usr/lib/gcc-lib/i486-linux/3.3.2/../../../libz.so when searching for -lz

Intrebarea mea e: ce sunt LDFLAGS-urile si CFLAGS-urile? Si eventual daca stie sa-mi zica cineva ce reprezinta LDFLAGS-urile care le am eu in Makefile?

Multumesc  

FLAGS = "steaguri", optiuni de compilare, switchuri.
C - pentru C, CXX - pentru C++
LD - pentru LD, linkerul GNU

Vezi ce versiune gcc ai cu  "gcc --version", si apoi: http://gcc.gnu.org/onlinedocs/

Si ca o solutie de moment:
Eventual incearca sa scoti flagul -lz, poate-poate reusesti...

Multumesc de ajutor, am mai aflat ceva...
Am gcc-3.3 (GCC) 3.3.2 (Debian).

Am mai progresat (cred ) cu compilarea. Totusi mai primesc cateva erori. Le pun aici, poate isi da cineva seama ce se poate face.
