Hi, I am trying to compile the vsftpd binary with support for ssl. I changed the builddefs.h to include #define VSF_BUILD_SSL but I get an error when make tries to to compile the file ssl.c: A part of the error after the make: .... gcc -c access.c -O2 -Wall -W -Wshadow -idirafter dummyinc gcc -c features.c -O2 -Wall -W -Wshadow -idirafter dummyinc gcc -c readwrite.c -O2 -Wall -W -Wshadow -idirafter dummyinc gcc -c ssl.c -O2 -Wall -W -Wshadow -idirafter dummyinc ssl.c:27:25: error: openssl/err.h: No such file or directory ssl.c:28:26: error: openssl/rand.h: No such file or directory ssl.c:29:25: error: openssl/bio.h: No such file or directory ssl.c:32: error: syntax error before '*' token ssl.c:32: warning: type defaults to 'int' in declaration of 'get_ssl' .... The ssl files that are needed are located at /usr/local/ssl/include/openssl I added /usr/local/ssl/include/openssl to the path and the errors did not change. I also included /usr/local/ssl/include/openssl in the INCLUDE environment variable. I also tried to change the make. Vsftpd make currently has: CFLAGS = -O2 -Wall -W -Wshadow and I changed it for CFLAGS = -O2 -Wall -W -Wshadow -I/usr/local/ssl/include/ -I/usr/local/ssl/include/openssl A chunk of the output after the make: From the ssl.c file. ( I added the line numbers at line 24.) /* * ssl.c * Routines to handle a SSL/TLS-based implementation of RFC 2228, i.e. * encryption. */ #include "ssl.h" #include "session.h" #include "ftpcodes.h" #include "ftpcmdio.h" #include "defs.h" #include "str.h" #include "sysutil.h" #include "tunables.h" #include "utility.h" #include "builddefs.h" #ifdef VSF_BUILD_SSL #include <openssl/ssl.h> #include <openssl/err.h> #include <openssl/rand.h> #include <openssl/bio.h> static char* get_ssl_error(); static SSL* get_ssl(struct vsf_session* p_sess, int fd); static int ssl_session_init(struct vsf_session* p_sess); Any one has any idea? Thanks!
