Dependencies installation docs are missing

[Nek]

I've tried to run examples but my complete lack of experience with guile prevented me from installing the dependencies (guile-sdl and guile-figl).

Can I have an example or a link to the manual?

[davexunit]

Thank you for attempting to install things.

Guile-sdl is easy to install: Grab the latest release tarball, version 0.5.0, from here http://www.gnu.org/software/guile-sdl/

You'll need SDL 1.2 installed and SDL_image, I think.

cd guile-sdl-0.5.0/
./configure --prefix=/usr
make
sudo make install

FIGL can be more problematic, since it's an as-of-yet unreleased library. I run off of the latest master, which has a small error in the documentation files that causes the build to fail. Let me try to walk you through the process:

git clone https://gitorious.org/guile-figl/guile-figl
cd guile-figl
autoreconf -vif
./configure --prefix=/usr
make
sudo make install

You will probably encounter a syntax error in the low-level-gl.texi, to fix it you will need to join the lines 19152 and 19153 together, I think. There are a lot of warnings that get output, but only one actual error. The documentation is auto-generated from the OpenGL docs and there are still a few bugs in the generator.

I hope this helps. I should move this information into an INSTALL file or something. If/when I do an official release, I will look into bundling these dependencies with the release tarball to save everyone the headache.

[Nek]

Thanks for the instructions.

I've tried to follow but bumped into the problem with guile-sdl.

I'm on a mac (OS X 10.8.4) and have SDL installed with brew package manager.
So I had to configure SDL prefix:

./configure --prefix=/usr/ --with-sdl-prefix=/usr/local/Cellar/sdl/1.2.15/

Which gave me (it's not the full backtrace):

ERROR: In procedure open-file:
ERROR: In procedure open-file: No such file or directory: "/usr/include/SDL/SDL_ttf.h"

Ok. I reconfigured it:

./configure --prefix=/usr/ --with-sdl-prefix=/usr/local/Cellar/sdl/1.2.15/ --disable-ttf 

Which gave me (not the full backtrace again):

ERROR: In procedure open-file:
ERROR: In procedure open-file: No such file or directory: "/usr/include/SDL/SDL_video.h"

It looks like build script keeps looking for a part of SDL inside /usr/include/SDL/ despite being provided with the right SDL prefix.

I hope someone with a mac and adequate experience will jump on and give a helping hand.

[davexunit]

Hmm, that's a bummer. I'm not an OS X user but I might be able to use a friend's machine and investigate this issue. I would certainly like to see guile-2d to run on OS X.

[Nek]

When you get to this issue you can count on me to test the solution.
I'm rather excited about your creation and would love to use it for a game dev compo someday (better sooner then later :).

[davexunit]

Glad to see some interest in my project! Thanks for testing things out. I think I'll send an email to the guile-sdl developer and see what he thinks.

[Nek]

You are welcome! Let's see what he thinks.

[davexunit]

Here's ttn's (the guile-sdl dev) response:

"Thanks for the bug report. Unfortunately, until now, i was not even
aware of ‘--with-sdl-prefix’ -- ignorance is bliss! The next release
will fix that, but until then, you might try to specify these dirs on
the configure script command line via VAR=VAL pairs, something like:

./configure --prefix=$HOME/eval
CPPFLAGS=-I/usr/local/Cellar/sdl/1.2.15/include
LDFLAGS=-L/usr/local/Cellar/sdl/1.2.15/lib

I'm guessing at the leaf-dir names (include, lib); they need to be
chosen such that <SDL/SDL.h> can be found by appending to includedir,
and the shared object library (i think .dynlib under OSX) in libdir."

So, give that a try and see how it goes. If it doesn't, I can CC you when emailing ttn in the future.

[Nek]

I've tried to (the paths are correct :):

./configure --prefix=/urs/
CPPFLAGS=-I/usr/local/Cellar/sdl/1.2.15/include/
LDFLAGS=-L/usr/local/Cellar/sdl/1.2.15/lib --disable-ttf

And got:

ERROR: In procedure open-file:
ERROR: In procedure open-file: No such file or directory: "/usr/include/SDL/SDL_video.h"

[davexunit]

This is probably not the issue, but you have a typo here: --prefix=/urs/

[Nek]

Oh, you are right. And yes it's not the issue the backtrace stays the same with --prefix=anything or no prefix at all.

[davexunit]

Got this back from ttn, it's a bit hard to parse but maybe it will help a bit:

"This is from the script build-aux/guile-baux/k2c, which scans various
headers to produce the enums and flags init data, in src/k/. Although
k2c can take ‘-I DIR’, the build system currently does not make use of
that option. There are two possible workarounds:

• Modify k2c (line 370) to substitute "/usr/include" w/ "DIR".
• Modify the src/k/Makefile.in pattern rules ‘.kf.c’ and ‘.kp.c’ to
  add ‘-I DIR’ to the k2c invocation, and invoke config.status at
  top-level to re-instantiate src/k/Makefile.

Both of these probably require "make -C src/k/ clean" (at a minimum) to
ensure known-good (re)start state."

[Nek]

It helped a bit. :)

Now I've got the next problem:

Now I'm sure we need someone with a Mac and a knowledge of make.
Also there will be problems with SDL. SDL apps don't work out of the box on Macs and need a C wrapper to run.

I wish I knew C and make.

[davexunit]

This is quite the rabbit hole we're going down. Where did you install guile from? I install 2.0.9 from source to /usr. Where is libguile.h? This could be yet another brew problem.

[Nek]

It's inside

/usr/local/Cellar/guile/2.0.9/include/guile/2.0/

I'll try to install guile and everything needed from sources.

[davexunit]

Ah, installed via brew. That would explain why it cannot find the C headers. You'll need to get that path into GCC's include path via the -I flag.
