Hi all,

I installed libgcrypt-1.4.0 and want to compile this code (which is from
"selftest()" function of "cipher/blowfish.c"):

-------------------- test.c ------------------------
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <gcrypt.h>

int main(){
BLOWFISH_context c;
byte plain[] = "BLOWFISH";
byte buffer[8];

bf_setkey((void *) &c, (const unsigned char*)
"abcdefghijklmnopqrstuvwxyz", 26);
encrypt_block((void *) &c, buffer, plain);

if(memcmp(buffer, "\x32\x4E\xD0\xFE\xF4\x13\xA2\x03", 8)){
printf("Blowfish selftest failed (1).\n");
exit(-1);
}

decrypt_block((void *) &c, buffer, buffer);
if(memcmp(buffer, plain, 8)){
printf("Blowfish selftest failed (2).\n");
exit(-1);
}

return 0;
}

When I give " gcc -Wall -lgcrypt -L/usr/local/lib/ -I/usr/local/include/ -o
test test.c -L/usr/local/lib/libgcrypt.so -Wl,--rpath -Wl,/usr/local/lib"
command to compile the code, it gives these errors:

test.c: In function 'main':
test.c:9: error: 'BLOWFISH_context' undeclared (first use in this function)
test.c:9: error: (Each undeclared identifier is reported only once
test.c:9: error: for each function it appears in.)

test.c:14: error: 'plain' undeclared (first use in this function)

How can I fix this error? Please help. Thanks a lot.
Best regards.
