If you are a novice user, and don't know how to compile things, try contacting your local guru first (get them to do it for you :-). Please understand that I don't have time to walk newbies through the whole installation procedure. 1. READ this entire file. Part A, below, tells what to do if you want to use NcFTP with a command-line editor. Part B tells you how to configure the Makefile to compile the program for your system. Part C tells you how to configure NcFTP's optional features. Part D tells you how to contact me if you want to report a bug or submit new code to the program. 2. EDIT the Makefile, making any necessary changes described in parts A, B, or C. Don't forget to read the directions in the Makefile, so you don't forget any needed libraries, etcetera. 3. You can also change the program's default behavior by editing defaults.h. 99% of the time you don't need to do this, so you can skip this step. If you have problems, you can mail me, but please try your best to install it without my help. I'm quite tired of responding to lazy SunOS users because they didn't bother reading the directions so that they would have known that they needed to use GCC. I _do_ want to hear from you if you have comments or bug reports/fixes. I would also like to hear from you if you had a system that wasn't covered in sys.h, so I can add an entry for other users of your system. The latest version of ncftp is available in the directory: cse.unl.edu:/pub/mgleason This machine is heavily used by students and faculty alike, so please do not call during working hours (9AM - 5PM American Central time). In fact, I have a cron entry that changes all the file permissions to public unreadable during that period, so you won't be able to download anyway. I am grateful to Shari Deiana and the University of Nebraska for making this possible! Part A. Installing with a command line editor: ---------------------------------------------- As of this release, GNU Readline and Chris Thewalt's Getline command-line editing and history facilities are supported. Neither are included with the ncftp sources. You can find Getline at: ce.berkeley.edu:/pub/thewalt/getline.tar.Z (note: use 'ls', not 'dir!') and Readline is in the directory: prep.ai.mit.edu:/pub/gnu To install Readline, you will need to know where libreadline.a and the header <readline/readline.h> are. You will need to link libreadline.a and libcurses.a (or libtermcap.a) with ncftp (see the Makefile). Good luck on trying to compile it. It is not an easy thing to do! In the Makefile, you will need to add -DREADLINE to PDEFS, add -lreadline -lcurses to LIBS, and edit the HDRDIRS and LIBDIRS lines. This stuff is already in the Makefile, so you can just uncomment it. To install Getline, you need to know where libgetline.a and it's header (getline.h) are. In the Makefile, you'll need to add -lgetline to LIBS and edit the HDRDIRS and LIBDIRS lines. This stuff is already in the Makefile, so you can just uncomment it. DO NOT bug me if you can't figure out how to compile Getline or Readline. Contact their respective authors instead. It is not essential that you use them. Part B. System Dependencies: ---------------------------- NcFTP may need work-arounds for some things due to the differences in implementations of unix. The following systems are taken care of automatically. For these systems, you should just be able to type 'make' (but proceed to part C): Silicon Graphics IRIX AIX SINIX Ultrix NeXT Pyramid OSx Otherwise you will have to configure ncftp manually. Important for "Yellow Pages" users: Don't forget to link the library that includes the YP/NIS version of getpwuid(), etc. Otherwise the program won't be able to expand ~username/path/name type pathnames, and maybe even ~/path/name types of pathnames. If you're wondering why the program isn't opening your rc file, this could be the cause. You will need to add these things to the SDEFS line in the Makefile as applicable. As an example, if I say 'add -DFoobar to SDEFS,' find the line in the Makefile that reads 'SDEFS=' (or 'SDEFS=-DFoo2') and change it to 'SDEFS=-DFoobar' (or 'SDEFS=-DFoo2 -DFoobar). If your system is listed below, follow the directions and then you ready to go to part C, below. Sun Microsystems' SunOS/Solaris: Use an ANSI compiler such as gcc (set CC=gcc in the Makefile), or acc (set CC=acc). The regular 'cc' is not an ANSI compiler. You could also run something like 'ansi2knr' on the sources and hope it works. You will probably need to link both the curses and termcap libraries if you use -DCURSES (see below). Hewlett-Packard HP-UX: If you have 7.0, you'll need to find a copy of <ftp.h> from somewhere (8.0 has it though). Then set CFLAGS= -Aa. You may also need to use gcc if your compiler is non-ANSI. Note that for HP-UX, the default terminal escape codes are for HP terminals, so you should probably link termcap/curses in so it will get the ANSI sequences if you're on a vt100, etc., terminal connected to your HP-UX machine. SCO Unix: Add -DSCO324 or -DSCO322 (as appropriate) to SDEFS, and -lsocket to LIBS. SCO Xenix 2.3.4: Add -DSCOXNX to SDEFS and add "-lsocket -ldir" to LIBS. Bull DPX/2: Add -DBULL to SDEFS, add -linet to LIBS, and use gcc. Sequent's DYNIX: Use gcc and add -DDYNIX (if necessary) to SDEFS. You may also be short several string functions which you will have to get elsewhere, and perhaps mktime and strftime. You can get all that stuff from the BSD sources (like ftp.uu.net). Please bug Sequent to update their libc library! If your system doesn't fit any of those, things will be trickier. Answer all these questions and add to the SDEFS line. You may want to try each option one at a time until everything works. * Is your system closer to System V or BSD? Your SDEFS line should have either -DBSD or -DSYSV. If you don't know, try leaving it blank first; some compilers automatically define it for you. * Add -DNO_CONST if your compiler chokes on the const directive. You will know if you need to add this if the compiler spits out errors saying it doesn't know what 'const' is. * As I said above, you will need to link special libraries if your system is running Yellow Pages. * Add -DSYSSELECTH if you need <sys/select.h> included for definitions of fd_set, etc. * Add -DNO_UNISTDH if you don't have <unistd.h>. If the compiler complains about not being able to open <unistd.h> add this. * Add -DNO_STDLIBH if you don't have <stdlib.h>. If the compiler complains about not being able to open <stdlib.h> add this. * Add -DNO_UTIMEH if you don't have <utime.h>. If the compiler complains about not being able to open <utime.h> add this. * Add -DNO_MKTIME if you don't have the mktime() system call, and don't feel like getting the source for it and compiling it in with the program. If you define this, the program will not set the file modification times to match the ones on the remote host (no big deal). * Add -DGETPASS if you would rather use the standard getpass() system call, instead of our version, Getpass(), which takes more than 8 characters. You may want to define this if you are having problems compiling getpass.c. If you haven't given up on our Getpass(), you can try adding -DSGTTYB if you want to use a struct sgttyb instead of a struct termio. By default, BSD systems define SGTTYB automatically. You can also try adding -DTERMIOS to use a POSIX compliant struct termios instead. Don't pull your hair out trying to get the Getpass code to compile; if it gives you problems just define -DGETPASS and hope your system's getpass can handle passwords longer than 8 characters. * Add -DBAD_INETADDR if your inet_addr() function returns a struct in_addr instead of a u_long, as it should (in DG/UX 5.4.1). * Add -DBROKEN_MEMCPY if ncftp mysteriously dumps core when trying to open a remote host. I'm told that this happens because of some problem in System V's sockets don't like fprintf (and memcpy). * Add -DPTRTYPE=char if your pre-ANSI compiler complains about the way malloc() or free() are used, and in general does not like (void *) as a generic pointer type. * Add -DNO_STRFTIME if your system does not have strftime(). If you do, we won't try to use it. This means, however, you cannot use ``%'' values in your prompt. * Add -DNO_RENAME if your system does not have rename() (or the one it has is broken). If you do, we will use our own. * Add -DNO_STRSTR if your system does not have strstr(). If you do, we will use our own. * (Optional) Add -DGETCWDSIZET if your system's getcwd() takes a size_t as the second parameter instead of an int. * (Optional) Add -DHERROR if you know you have the herror() system call. * (Optional) Add -DU_WAIT if you know your wait system call takes a pointer to a 'union wait.' Defined automatically if you define BSD. * (Optional) Add -DHOSTNAME=\"machine.domain.nam\" if your system doesn't generate it's own hostname. To check this, compile ncftp then run it and type 'set.' Look at the variable anon-password. If the hostname is wrong, or if it is in the form of 'yourlogin' or 'yourlogin@machine' instead of 'yourlogin@machine.xxx.yyy,' re-compile it with HOSTNAME set to your machine's address, in the form of 'machine.xxx.yyy.' * (Optional) Add -DSTRICT_PROTOS if your compiler wants function prototypes for all functions, not just non-int-returning ones. Part C. Program Options: ------------------------ Add these as applicable to the PDEFS line in the Makefile. * -DGZCAT="path": If you have the GNU gzip package installed on your system, the program can try paging remote files compressed with gzip _and_ compress (instead of just compress). Add -DGZCAT=\"/full/path/to/zcat\" with GZCAT set to the path name of GNU's zcat/gzcat. * -DCURSES: Uses curses library to display boldface, underline, etc. By default ncftp uses hard-coded ANSI escapes (^[[1m etc.) to save the 100k or so the curses library adds. You will also need to edit the LIBS line in the Makefile to add -lcurses. You may need to add -ltermcap instead, or both -lcurses and -ltermcap. * -DSYSLOG: Define this to have ncftp log connections and transfers to the syslog. * -DNO_TIPS: Define if you want to cut a little fat at the expense of novice users. * -DGETLINE: If you want to use Chris Thewalt's getline input line editor and history facility, add this (and see below). * -DREADLINE: If you want to use GNU's readline input line editor and history facility, add this (and see the Makefile). If you do this, you also need to add -DCURSES (see above). * -DSOCKS: NcFTP is now compatible with the Socks library by David Koblas, at koblas@sgi.com. This lets you use NcFTP with a "firewall" gateway for enhanced site security. You can get the latest version from netcom.com:/pub/koblas. After you have compiled it, compile NcFTP with -DSOCKS added to PDEFS, and the pathname of the Rconnect.o file added to LIBS. * -DTRY_ABOR: Define if you want to try the 'ABOR' command from ncftp; The aborting code has had some problems, so by default the program 'aborts' by continuing to read input but not echoing output. * -DDB_ERRS: Define this if you want my Perror() function to be more verbose. You may want to do this if you are a programmer examining this code, and want to know where in the source the Perror's are coming from. Part D. Sending me patches: --------------------------- I apologize in advance for problems that my coding style may cause. The code itself is formatted such that each indent-level is a tab (intended to be equivalent to 4 spaces), and not spaces nor a combination of tabs and spaces. The reason for this, besides being more logical to me, is that I use a Macintosh editor to compose the code and I prefer it's indenting method. Another problem in my coding-style is that I write C-code intended for ANSI C compilers. This means that I will use the new-style function declarations and function prototypes, like: long Foobar(long, long, char *); long Foobar(long t0, long t1, char *str) { } as opposed to: long Foobar(); long Foobar(t0, t1, str) long t0, t1; char *str; { } Another thing may annoy you is that I always use function prototypes for any function I call, including functions that return an int. This is a good practice that I learned from the Macintosh programming world. So if you send me patches, please conform to my coding style so that 'patch' won't screw up, and also that some continuity will be preserved. Before you make your patch, you should be sure that you are using the most current version of the program. This is especially important if you are reporting a bug; I may have already fixed it! See the above info to get it via ftp. Major versions are always posted to comp.sources.misc. Bug reports are posted to comp.sources.bugs. Patches that need to be posted ASAP are posted to this group first, so it is advisable that you check this group. If you make changes to the code, surround your code in #ifdef/#endif blocks. Instead of doing things like #ifdef SunOS, use a name that describes the bug fix or feature, and not your system type, like #ifdef NO_UNISTDH, or #ifdef GETLINE. That way in case another system has the same problem, it can be added to sys.h without cluttering up the source code. Then, add the symbol you used to the end of cmds.c, in the 'CPP Hell' part of the version() command. You'll see a list of CPP symbols, so just add yours in a similar fashion, like #ifdef GETLINE/DStrs[nDStrs++] = "GETLINE";/#endif. If you don't know how to make a patch, here's how to do it. Things are easy if you've only changed one file. Then all you need to do pipe the output of diff -c into a file and send it to me, i.e. "diff -c cmds.c cmds.c.hack >pch." If you've hacked several files, the way I do it is to keep the originals in one directory (you did make a copy of everything first didn't you?) and the revisions in another directory. Then you change directory to the one with the originals and do "diff -c . ../revisions > ../pch." --mg (mgleason@cse.unl.edu)
