OSX, Cmake and Xcode

Postby shenle » Tue Feb 22, 2011 8:28 pm

I'm trying to compile VS on OSX 10.5.7 with cmake and Xcode-3.1.4
Taking this route since I've seen talk lately that the autotools will be abandoned soon by this project, with builds on all Unix-like systems relying on cmake.

I think cmake is being stupid. It doesn't find things even if you point them to it. The error messages contradict each other. See my current stage:

So first it complains of not finding libavcodec, libavformat and libavutil, then it lists the locations where it found them and still says they're missing. Same for cairo. And BTW libswscale.a is together with the others in /usr/local/lib

I'm out of ideas. I have a nice writeup on getting VS to compile from scratch on OSX, but I don't seem able to get past this last hurdle.

(FWIW I installed ffmpeg from source, and all of GTK2 packages via Fink)

IIRC, it tries to build a very simple test program to validate that everything actually works.
It must have failed there, I presume.

I don't think anyone has built with ffmpeg on OSX ever, but ffmpeg is (at the moment) optional, since VS UTCS doesn't use the feature yet.

Why is cmake thinking it's required?

Well, since I have ffmpeg installed and since it will be eventually required, it would be nice to compile with it.

Apart from that, I don't know how to tell cmake it's not required. :)

(also, cmake doesn't seem able to find swscale on Linux either but that's not a problem)

At least under Linux, that's a common situation when the user has the binaries of the involved library, but not the headers; in fact, given that not everyone will ever need the headers, Debian and derivatives have the habit to ship header files in separate packages, with the naming convention of adding a -dev suffix to the header package (libVSRocks = binaries, libVSRocks-dev = headers).

Is there a chance that things work in a similar way under OS/X ? If so, you might be lacking the header files for those libraries.

Things do work the same way in OSX under Fink at least, but:
1. Under Fink I installed both the libxxx and libxxx-devel where applicable
2. I installed ffmpeg from source the old fashioned way (./configure, make, sudo make install); the libraries and headers are there. Cmake finds them and lists the paths to them, then complains about not finding them. It doesn't make sense.
3. At least with one component of GTK2 (Cairo) Cmake finds the headers but not the binaries; both are installed. It finds the binary when I manually point to it, but then still complains. It doesn't make sense.

I fear there's no easier alternative than directly watch the code doing the offending checks; I haven't yet recovered from that time, long ago, when I peeked inside a configure script... :roll:

Okayyy...

So I tried to build an OSX binary with autotools... Beside not finding libpng and jpeg that Fink had installed (so I had to reinstall them from source) all went fine until the new autodocking code broke the compile:

I wonder if cmake is not the problem after all, and ffmpeg is just broken on OSX...
But I still don't know how to disable it, or GTK2 for that matter, in cmake.

Does it work if you change unit_jump.h:49 to the following (I have inserted "template " after the namespace delimiter)
Code: Select all
bool GameUnit< UnitType >::template TransferUnitToSystem( unsigned int kk, StarSystem* &savedStarSystem, bool dosightandsound )

Just committed attempts to solve the starsystem and ffmpeg issues.

The problem was that the header used
bool TransferUnitToSystem(unsigned int, class StarSystem*&, bool)

and the .cpp used
bool GameUnit<UnitType>::TransferUnitToSystem(unsigned int, StarSystem*&, bool) {
}

See the problem?
StarSystem is a class, but because it was not forward-declared, the scope of the forward declaration was just that function, so the "class StarSystem" in the header was a different StarSystem from the StarSystem in the .cpp

The fix was to remove the "class" from the function declaration and add it to the top of the file.

I also fixed detecting ffmpeg in autotools, and it seemed to build okay for me (not using xcode though). I'm still having trouble with Cmake on mac, where it seems to find duplicate libraries.
Cmake is using pkgconfig, but still ignores the library path it specifies for some reason, so I get a bunch of "duplicate dylib" messages followed by undefined symbols from libjpeg. (jpeg_write_scanlines, jpeg_std_error, etc.)

With autotools, I managed to get the game to run, but it crashed about a minute after launching into space, in the ogg and audio code (I forgot to do --enable-debug, darnit)

But I _do_ have bzip2 installed... including headers. Guess that's not good enough. Double grrr.

(edit) same error persists if I install the latest version of bzip2 outside of Fink from source.
Trying again to compile with ffmpeg disabled.

I did get it built (full command line for configure: --disable-ffmpeg --enable-macosx-bundle)

However it crashes while loading, before the main menu.

Attached stderr and stdout. It looks like it can't find some data files.

Also, the built vssetup doesn't launch.

okay, be patient, i'm working on a solution with cmake ;)

you won't come to success with configure :)

here is the solution:

the error was:
you can't use
Code: Select all
if(BLAH_INCLUDES AND BLAH_LIBS)
...
endif(BLAH_INCLUDES AND BLAH_LIBS)


this will always result to false.

you need to use :

Code: Select all
if(NOT BLAH_INCLUDES STREQUAL "")
  if(NOT BLAH_LIBS STREQUAL "")
....
  endif()
endif()



so happy coding with macos ;)

Actually I did get a binary built with autotools, but it crashes when it can't find some data files (which are there BTW).

But I'll see if I can make cmake work your way.

So I modified findFFMPEG.cmake as you suggested and it still complains of ffmpeg not found.

OK that works for ffmpeg.

It still can't gind GTKGL (includes and libs) and Cairo (libs only - it does find the includes). No amount of findgtk2.cmake tweaking has resulted in any progress. Can't figure out how to disable the GTK2-dependent portions of the build (setup) either.

I was able to get over the GTK2 problem by deleting findgtk2.cmake altogether from the source tree. Then cmake proceeded and I could generate a project. Compiling in xcode resulted in errors, so no binary.

Here are the errors:

1.common.h, line 168: 'UINT64_C' was not declared in this scope (this error repeats 3 times)
Code: Select all
    if ((a+0x80000000u) & ~UINT64_C(0xFFFFFFFF)) return (a>>63) ^ 0x7FFFFFFF;


2. png.h, 795: forward declaration of 'struct png_struct_def'
Code: Select all
typedef struct png_struct_def png_struct;


3. vid_file.cpp, 73: 'img_convert' was not declared in this scope
Code: Select all
#ifdef DEPRECATED_IMG_CONVERT
            img_convert(
                (AVPicture*) pFrameRGB, PIX_FMT_RGB24,
                (AVPicture*) pNextFrameYUV, pCodecCtx->pix_fmt,
                pCodecCtx->width, pCodecCtx->height );


4. vsimage.cpp, 870: invalid use of undefined type 'struct png_struct_def'
Code: Select all
if ( setjmp( png_ptr->jmpbuf ) ) {
        png_destroy_write_struct( &png_ptr, &info_ptr );
        return BadFormat;
    }

Paste the full log, the context is usually even more important than the error line.
