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!
I need to install it from a source tarball. Where can i get the tarball? I don't find in the downloads openssl page: http://openssl.org/source/ thanks!
Here's a hack but it works You need to fool vsftpd by faking locations of include files and libraries for openssl My openssl installation is at /usr/local/openssl. Under here you will find include/openssl and lib. To get vsftpd to compile and link, you need three symlinks: 1. Go to /usr/include and execute: ln -s [Path to your openssl install]/include/openssl openssl This sets up a symlink (/usr/include/openssl) that points to your actual openssl include file directory. This will get you through compile but not link. 2. Go to /usr/lib and execute: ln -s [Path to your openssl install]/lib/libcrypto.a libcrypto.a ln -s [Path to your openssl install]/lib/libssl.a libssl.a This sets up symlinks in /usr/lib that point to your actual openssl libraries. Once these symlinks are in place, the link should also work. One note: My system is AIX, where shared libraries have a .a extension. Obviously, you will need to modify step 2. if your OS has a diferent convention. Look in [Path to your openssl install]/lib to find out. Also, this doesn't address warnings compiling sysutil.c but those seem benign anyway.
... one more thing If you're compiling open ssl from the source tarball, you can ignore previous poster's comment about openssl-devel. That's included
Falko, I am using a Linux from scratch system, compiled with very few services and that fits under a 64MB CF card.... The file http://www.openssl.org/source/openssl-0.9.8g.tar.gz is the one I used to compile support for SSL in my system. It compiles all well, and SSL works perfectly with other services. For example I have SSH installed and it depends of Zlib and SSL. anewby, you were right. I follow your steps (almost the same,I did setup the 2 links for libcrypto.a and libssl.a in my /usr/lib/ ,and I did the softlinks in the /usr/include and then add to the Makefile this -I/usr/include). Now the compiling process passes the ssl.c properly but now I get another error: gcc -c ssl.c -O2 -Wall -W -Wshadow -I/usr/include -I/usr/lib -idirafter dummyinc gcc -c sysutil.c -O2 -Wall -W -Wshadow -I/usr/include -I/usr/lib -idirafter dummyinc <--- These 2 compile OK now gcc -c sysdeputil.c -O2 -Wall -W -Wshadow -I/usr/include -I/usr/lib -idirafter dummyinc <--- This one throws warning sysdeputil.c: In function `do_sendfile': sysdeputil.c:663: warning: null argument where non-null required (arg 3) gcc -o vsftpd main.o utility.o prelogin.o ftpcmdio.o postlogin.o privsock.o tunables.o ftpdataio.o secbuf.o ls.o postprivparent.o logging.o str.o netstr.o sysstr.o strlist.o banner.o filestr.o parseconf.o secutil.o ascii.o oneprocess.o twoprocess.o privops.o standalone.o hash.o tcpwrap.o ipaddrparse.o access.o features.o readwrite.o ssl.o sysutil.o sysdeputil.o -Wl,-s `./vsf_findlibs.sh` /storage/tools/bin/../lib/gcc/i686-pc-linux-gnu/3.4.3/../../../../i686-pc-linux-gnu/bin/ld: cannot find -lssl <---- The linker throws error collect2: ld returned 1 exit status make: *** [vsftpd] Error 1 Looks like is the linker the one that is complaining right now.The -lssl seems to look for the ssl library but doesn't find it. I found a file in the vsftpd-2.0.6.tar.gz tarball that is called vsf_findlibs.sh As I could see in the file, it does search for the available libraries and then report which libraries were found. If I run it manually, this is the output before the make: ./vsf_findlibs.sh egrep: tcpwrap.o: No such file or directory egrep: sysdeputil.o: No such file or directory -lcrypt -lcrypt -ldl -lnsl -lresolv -lutil egrep: ssl.o: No such file or directory This is the output after the make: ./vsf_findlibs.sh -lcrypt -lcrypt -ldl -lnsl -lresolv -lutil -lssl -lcrypto ...so it finds all the libraries. I don't really know why the linker throws the error. After compiling the ssl.o is in the same folder as the Makefile, so it should have to link it properly. Any ideas?
