Compilation problem on OSX Leopard about gource HOT 37 CLOSED

[deleted comment]

Maybe someone with OSX could tweak the configure.ac file to get this to work and
submit a patch?

I took a brief look and got it a bit further (but not working).  Here's what I 
did:

Built each of FreeType2, ftgl, pcre, SDL, and SDL_image from source with 
./configure, make, sudo make 
install.  That got all the libraries in usr/local/lib where  Gource's configure 
finds them ok with no 
modifications.

Then I patched main.cpp (see attached) to hide the Windows console calls that 
don't exist on Mac OS X.

I don't have the time or the know-how to fiddle with autoconf, so I manually 
edited the src/Makefile to 
replace the LIBS entry

-lSDL

with

-lSDLmain -lSDL -framework Cocoa 

per the FAQ entry here:

http://www.libsdl.org/faq.php?action=listentries&category=7#55

That got everything to build without error.  However, there is a segmentation 
fault almost immediately upon 
start-up with no other messages, so there is still something fundamental 
missing.  I'm out of time to look at it 
further, but maybe this helps someone else who's interested.

It seems that they might have instructions at http://www.libsdl.org/faq.php?
action=listentries&category=3#21 , but I'm afraid I don't have any autoconf 
experience 
so I'm not sure if that is helpful?

I was just thinking "There's probably an sdl.m4 somewhere" and there it is... 
in the
FAQ :) I might change it to use this on the weekend.

I've just changed configure.ac to use sdl.m4 as per the FAQ. 

Would someone like to maybe check out the code from github
(http://github.com/acaudwell/Gource) and see if we're further along?

Thanks.

Yes, this gets it a little further. The next problem is that ftgl isn't found, 
I wonder what 
is missing there now

It now builds successfully (if you have previously built and installed the 
prerequisites, like ftgl).  But it still 
crashes on start-up as follows:

It appears the ftgl problem is actually an issue with Macports. Will report 
back when I 
know more.

Craig: 

Thanks. That should be easy to fix. it's because one global object (display) is
calling another global object (texturemanager) in its constructor before the 
other
has been constructed... it just happens that on the other platforms they getting
constructed in a different order.

I will change how that works.

[deleted comment]

My last commit should fix that crash.

Also now using pkg-config to get the correct FTGL cflags and libs.

Might be worth another look.

The crash is fixed, thanks.  For me (building everything from source) the 
pkg-config made no discernible 
difference in the build process except I had to build and install pkg-config to 
get configure to run.  Maybe it 
will help the MacPorts folks.

What I now see is that it bails out as soon as it starts to draw a window with:

failed to load image /usr/local/share/gource/beam.png

The file exists and I have read access to it:

% ls -l /usr/local/share/gource/beam.png
-rwxr-xr-x@ 1 root  wheel  358 Sep 30 19:24 /usr/local/share/gource/beam.png

Not sure offhand how to debug that further.

I think we're almost there.

You probably need libpng (and libjpeg if you want to load jpegs though none are
included):

"As of SDL_image 1.2.5, JPEG, PNG, and TIFF image loading libraries are 
dynamically
loaded, so if you don't need to load those formats, you don't need to include 
those
shared libraries. libpng depends on libz, and libtiff depends on both libz and 
libjpeg."

I will make autoconf check for those.

Checking for those now.

Excellent.  Built libpng and libjpeg, rebuilt SDL_image, then gource, and now 
gource is happy.  I'm currently 
watching Larry Wall create Perl 20 years ago, all the more impressive since the 
data were converted from 
something to Perforce and then Perforce to git.

Haha! Awesome.

Works for me now. Thanks

Cool. Seb: does that mean you got it to work with FTGL 2.1.2 or did you need 
2.1.3?

Btw, I edited the SDL and FTGL #include paths the other day as I was having 
trouble
building on windows, I wonder if they are still found on Mac?

Needed 2.1.3, there's no working 0.2.1.2 for OS X, it appears. Shouldn't be a 
problem, 
though, as I'm slowly convincing the macports devs to ship 2.1.3 as a 
ftgl-devel 
package or something.

New version contains these fixes so this should work I hope :)

There is still some problem it seems:

http://trac.macports.org/ticket/22192

There a few possibilities I would guess:

* the order I'm linking things is wrong
* AX_CHECK_GLU is producing the wrong libs on some Macs
* some of the libaries themselves (SDL, SDL_image, FTGL) link against different
versions of GL - hard for me to do anything about that.

It appears Gource builds without AX_CHECK_GLU (at least for me) since FTGL 
seems to
have all the Opengl symbols (somehow, not linking expert), though it seems like 
a
hack just to take that out, and I'm not sure that's the problem.

Anyone have any bright ideas?

I was, after hours of having the same problem, finally able to figure it out.

When you run ./configure without any arguments, there's a linking problem that
eventually creeps in.  Some of the libraries will link against Mesa (the X11 
OpenGL
implementation), and some of the libraries will link against the OpenGL 
framework
that comes with Quartz (I think?).  This makes it go boom when it tries to load 
in a
texture.

If you run "./configure --without-x", the Mesa libraries don't get linked in and
everything works fine.  Is there a way to have this the default on Leopard?

I also had issues with the version of SDL that came via Fink, and the version 
that
came via "Ports".  Both seem to work, but one (I think Fink) has the SDL 
libraries in
/sw/include while the other has them in /sw/include/SDL and Gource prefers the
latter.  If you run into a case where ./configure works but then make complains 
about
missing SDL headers, open the src/Makefile and src/core/Makefile and change the
CPPFLAGS line at the top of each from -I/sw/include/SDL to -I/sw/include and you
should be good to go.

I still had to clone and manually compile FTGL, as neither Fink nor MacPorts has
2.1.3~rc5 as of this writing.

But!  But!  Once I did all of that, it works like a charm.  (And I learned more 
than
I ever wanted to know about gdb and otool and dynamic linking in the process.)

Interesting. Thanks for the report.

I've been trying to get it to work on Leopard on a borrowed testing Mac at work.

The main problem I am seeing is this warning when you run Gource about SDL and
SDL_Image implementing the same functions (I'm using macports):

objc[58644]: Class SDLTranslatorResponder is implemented in both
/opt/local/lib/libSDL-1.2.0.dylib and /opt/local/lib/libSDL_image-1.2.0.dylib.

implementation from /opt/local/lib/libSDL_image-1.2.0.dylib.

I managed to get Gource to work by moving -lSDL_image after -lSDL in the LIBS 
(which
it probably should've been anyway I guess) though that warning still appears 
whenever
it runs.

I just tried --without-x and I still get the same warnings so it didn't seem to 
be
the issue (for me), though people making a port/package for Macs may want to 
include
that setting. I'm not quite sure how to make this the default.

If you have any idea how to stop the warnings that'd be a great help.

Btw FTGL 2.1.3 rc5 is now in Macports (Thanks to Seb for getting them to update 
it).

I fiddled with this some more on my Leopard MBP.  I upgraded to Gource 0.16b2
(bceee7..57b15a), cleaned out my manually-compiled FTGL, and installed 
2.1.3~rc5 from
MacPorts.

From there, I've tried two different setups.

Setup 1: MacPorts libsdl 1.2.14, libsdl_image 1.2.8
Pro: Works without twiddling Makefiles
Con: Warnings about dual implementation of SDL methods

Setup 2: Fink libsdl 1.2.14-5, libsdl_image 1.2.8-2
Pro: No warning about dual implementation
Con: Have to twiddle Makefiles to change /sw/include/SDL to /sw/include

Neither is perfect, and both still require you to ./configure --without-x, but 
both work.

I think I have fixed the SDL header issue.

If I can find an example of the correct way to turn off the X package in 
configure on
Macs I will do that too.

This appears to be fixed in 0.16beta4

I concur with patnotz -- this now builds on Leopard with a clean repo and no 
extra
configuration.  Yay!

Yep I've defaulted configure to build without x on Macs (--with-x will give you 
the
old behavior).

The SDL_image warnings are still there...

I tried Fink, and as reported, no warnings.

Using MacPorts, still getting issues at make:

Hi.

Sounds like you have an old build of SDL before SDL 1.2.10 when 
SDL_GL_SWAP_CONTROL
apparently was added. I'm pretty sure if you update your SDL libraries it will 
work.

I will bump the minimum version to 1.2.10.

@acaudwell

I have:

$ port list installed | grep sdl
libsdl-devel                   @1.3.0-5179     devel/libsdl-devel
libsdl_image                   @1.2.8          devel/libsdl_image

They are the latest packages on MacPorts (there's also libsdl @1.2.14).

Update: Uninstalled libsdl-devel from MacPorts, installed regular libsdl 
instead. Had to 
reinstall libsdl_image after the change, but now it works perfectly!

Cool. So your version of SDL was too new instead of too old :)
