问题
I study C language in ubuntu 18.04(gcc 7.3)
When the make all command is entered, this error occurrs:
/usr/bin/x86_64-linux-gnu-ld: can not find -lkeccak
The Makefile is as follows.
CC=gcc
CFLAGS=-03 -fomit-frame-pointer -msse2avx -mavx2 -march=native -std=c99
all:
$(CC) $(CFLAGS) -c Lizard.c main.c randombytes.c sha512.c
$(CC) $(CFLAGS) -o Lizard Lizard.o main.o randobytes.o sha512.o -lkeccak
run: all
./Lizard
new:
make clean
make all
./Lizard
Currently the libkeccak.a file is in the same directory as the Makefile and
it is also in the /usr/include directory.
I do not know the solution method at all.
Please, Help me.
回答1:
The -l option is for linking dynamic libraries (like libkeccak.so). Static libraries are linked into the executable already if they're in one of the "standard" directories, so there's no need to provide the option -lkeccak.
If you want to explicitly tell GCC to link a static library,
gcc -l:/path/to/libkeccak.a
