Hello, I'm programming an application that only gets and sets FIPS mode. Here is my Makefile: -------------------------------------------------------------------------------------------------------------------------------------------TOOLCHAIN:=/home/marcos/work/nitere/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux/bin:$PATHCROSS_COMPILE:=arm-linux-gnueabihf- OPENSSLDIR = /usr/local/ssl#INCLUDES = -I$(OPENSSLDIR)/include -I$(OPENSSLDIR)/fips-2.0/include -I$(OPENSSLDIR)/libINCLUDES = -I$(OPENSSLDIR)/include -I$(OPENSSLDIR)/fips-2.0/includeLIBS= -Lcrypto PATH:=${TOOLCHAIN}:${PATH} all: ${CROSS_COMPILE}gcc fipsctl.c -o fipsctl $(INCLUDES) $(LIBS) clean: rm -Rf *.o fipsctl------------------------------------------------------------------------------------------------------------------------------------------- And here is my code: -------------------------------------------------------------------------------------------------------------------------------------------#include <openssl/crypto.h>#include <stdio.h> int main ( int argc, char *argv[] ){ if(argv[0] == "get") { int mode = FIPS_mode(); if(mode == 0) { printf("*** FIPS module is disabled. ***"); } if(mode == 1) { printf("*** FIPS module is enabled. ***"); } } else if(argv[0] == "set") { printf("*** Enabling FIPS module. ***"); } else { printf("*** Error: unsupported option. ***"); }} ------------------------------------------------------------------------------------------------------------------------------------------- When I try to cross-compile, I get this error: marcos at marcos-X450LD:~/work/nitere/app/nitere$ makearm-linux-gnueabihf-gcc fipsctl.c -o fipsctl -I/usr/local/ssl/include -I/usr/local/ssl/fips-2.0/include -Lcrypto/tmp/ccSQhRme.o: In function `main':fipsctl.c:(.text+0x1a): undefined reference to `FIPS_mode'collect2: error: ld returned 1 exit statusmake: *** [all] Error 1 Does anybody know why I'm getting this error? Any tip will be very helpful,Thanks. -------------- next part -------------- An HTML attachment was scrubbed...
