Compiling NPP on Ubuntu questions

[nppangband]

I am trying to compile NPP on the latest verion of Ubuntu. Once everything is in place, I understand that it is a three step process ("./autogen.sh", then "./configure", and finally "make".
It seemed to indicate I got through the first two steps OK. With the make command, I got:

/bin/bash: line 1: cd monster: No such file or directory
make[3]: *** [subdirs] Error 1
make[2]: *** [all] Error 1
make[1]: *** [subdirs] error 1
make: *** [all] error 1

Any thoughts? This is based on the NPPAngband source found at github, work-in-progress branch. Most of the linux specific files in there were taken from Angband at github, v 3.1.2, because that is what NPP is currently based on.

Thanks in advance for anyone who can offer any suggestions as to what to do.

Of course, before doing any of that, I went to http://rephial.org/wiki/Compiling and copied this line into a terminal:

sudo apt-get install autoconf gcc libc6-dev libncurses5-dev libx11-dev \
libsdl1.2-dev libsdl-ttf2.0-dev libsdl-mixer1.2-dev libsdl-image1.2-dev \
libgtk2.0-dev libglade2-dev

I suppose my question is, do you have a src/monster/ directory? If not, you'll need to adjust src/Makefile to remove 'monster' from SUBDIRS. (The autoconf system uses the list in SUBDIRS to work out what it needs to compile, so if there's something in there that you don't have / something you don't have in there that you need then the system won't work.)

Does that make sense?

[Nick]

takkaria has it in one - the sundirs line in your src/Makefile should read

SUBDIRS = gtk

It may be helpful (or misleading ) to look at the FA source on github for comparison for this sort of thing - it has gone with almost all the V3.2/3.3 low level code, but hasn't moved to the monster, object, player subdirectories.

[nppangband]

Yes, that was it. Thank you both. The only subdirectory NPP has with source code is for GTK.

Now on to round 2, where the questions get tougher, but you get double the points........

I got a little further, and worked through a couple more error messages. I had to remove two files from makefile.std that I don't have in NPP. Once I did that, I retried the "make" command, and I got the error:

make[3]: *** No rule to make target 'NPPAngband'. Stop.
make[2]: *** [all] Error 1
make[1]: *** [subdirs] Error 1
make: *** [all] Error 1

I thought this one was strange because I would think it would give me that error first, before the error messages related to specific makefiles.

BTW: Do I have to do the autogen.sh and configure commands each time I make, or just once?

One of the files I removed from makefile.std was snd-sdl.o. Did I read that rignt in that file has functions needed for sound support under sdl? IIRC I have the same functions buried somewhere in another file in NPP, but I will have to confirm that.

I shoudl mention that my eventual goal is not only to confirm everything works fine in the various Linux plaforms, but also hopefully have the same Linux packages that regular angband has, so people can just download and play NPP in Linux. Then I just have to fulfill my longstanding dream of getting a macbook pro and I can work directly on all three platforms.

OK, I think that replacing

angband: $(OBJECTS)

with

$(PROG): $(OBJECTS)

should fix that.

You should not need to redo autogen.sh and config, as a general rule.

Yes, snd-sdl is for use of sound in SDL - note that you will have to have several SDL-related packages installed for the SDL port to be usable on your machine (just use whatever GUI your version of Ubuntu uses and look for things like SDL_mixer, SDL_ttf, SDL_image).

Note that the full V build system has makefiles in every directory, including the top level one. This helps for installing on linux rather than just running from the local directory, which is not strictly necessary but probably a good idea. Again, using FA1.2 as a template may help.

Then I just have to fulfill my longstanding dream of getting a macbook pro and I can work directly on all three platforms.

My current setup (which I have had for the last couple of years) is to have a mac with virtual linux and windows machines. IMHO this is pretty much ideal.

Yes, it did! Thank you very much. I have some compiler warnings and errors to work through in the main.*** files, but I am on my way now.

I remember you have make some NPP release packages for previous versions, I am also going to look through those and see what you did.

I was not quite sure what they do, but I added all of them today anyway, along with a bunch of other files. I think some of them have to do with github rather than compiling, but that can all be sorted out later. I will check out FA as well.

NICE!

Thanks again for the help. I am getting closer to compiling. This is the latest error that I need help on: I kind of understand what the linker command line is but I am not sure what to do about it:

/usr/bin/ld: snd-sdl.o: undefined reference to symbol 'SDL_GetError'
/usr/bin/ld: note: 'SDL_GetError' is defined in DSO /usr/lib/libSDL-1.2.so.0 so try adding it to the linker command line
/usr/lib/libSDL-1.2.so.0: could not read symbols: Invalid operation
collect2: ld returned 1 exit status
make[3]: *** [nppangband] Error 1
make[2]: *** [all] Error 1
make[1]: *** [subdirs] Error 1
make: *** [all] Error 1

ISTR you said earlier in the thread that you had got rid of snd-sdl.c, because those functions were in some other .c file now? If that's right then you shouldn't be linking snd-sdl.o, and you need to remove it from the list of .o files which forms ANGFILES (or MAINFILES, or whatever it is).

If that's not right, and you do build snd-sdl.o from snd-sdl.c, then my guess is that something is missing from your SDL installation. But since libSDL-1.2.so.0 is a very low-level core component of SDL, it's likely to be there if you have installed all the SDL libs.

The reason I added it back in because I got a compiler error on main-sdl because it calls one of the functions in snd-sdl-o.

I installed the recommended dependencies from the compiling page on rephial (sudo apt-get install autoconf gcc libc6-dev libncurses5-dev libx11-dev \
libsdl1.2-dev libsdl-ttf2.0-dev libsdl-mixer1.2-dev libsdl-image1.2-dev \
libgtk2.0-dev libglade2-dev ) Did I miss anything?

Looks like there is already a thread on this one a couple months ago & it is an ubuntu issue.
