[fixed] Compiling MegaGlest from trunk does not work for Mac OS X (10.6.5)

[macuser]

Hello,

compiling MegaGlest from trunk (as described in Wiki entry "MG/Mac Compiling") does not work for Mac OS X (10.6.5):
"svn co https://megaglest.svn.sourceforge.net/svnroot/megaglest/trunk megaglest" works ok, of course.
But "cmake -GXcode" in directory "megaglest" ends with a problem about XerxesC:

Code: [Select]

mb:megaglest macuser$ cmake -GXcode
-- Build type for this compile will be:
-- Detected GNUC Compiler...
CMake Error at /opt/local/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:91 (MESSAGE):
  Could NOT find XercesC (missing: XERCESC_LIBRARY XERCESC_INCLUDE_DIR)
Call Stack (most recent call first):
  /opt/local/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:252 (_FPHSA_FAILURE_MESSAGE)
  mk/cmake/Modules/FindXercesC.cmake:23 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
  source/shared_lib/CMakeLists.txt:54 (FIND_PACKAGE)

-- Configuring incomplete, errors occurred!
How did you compile this from trunk for Mac OS X 10.6.5?
Thanks for your hints and a Happy New Year 2011!

[macuser]

Sorry to bump, but someone had this compiled, or not? Any hints are welcome, thanks.

By the way, the above linked Wiki "MG/Mac Compiling" seems to miss something re. the 3rd party libraries:

Retrieve the 3rd libraries from here : and extract the contact of the archive in your library directory ~/Library/Frameworks

After "here:" there is no link, so were do we get these from?

Now I tried again (after update of Xcode), but it failed again:

Code: [Select]

Updated to revision 1518.
mb:megaglest macuser$ cmake -GXcode
-- Build type for this compile will be:
-- Detected GNUC Compiler...
-- Found CURL: /usr/lib/libcurl.dylib
-- curl version=[7.19.7]
-- (please visit http://curl.haxx.se/libcurl/ to find a newer version)
CMake Error at source/shared_lib/CMakeLists.txt:69 (message):
   CURL version = [7.19.7] we require AT LEAST [7.21.0]

-- Configuring incomplete, errors occurred!

How do I update curl to at least 7.21.0 on Mac OS X? The following did not work:

Code: [Select]

bash-3.2$ sudo port update curl
Password:
dlopen(/opt/local/share/macports/Tcl/macports1.0/MacPorts.dylib, 10): no suitable image found.  Did find:

    ("package ifneeded macports 1.0" script)
    invoked from within
"package require macports"
    (file "/opt/local/bin/port" line 39)

Hi macuser,

at the moment i'm working on modifications to get MG build on FreeBSD using cmake. After that is finnished sucessfully i'll try to get into it on MacOSX. I don't have any skills in Xcode, but if we work together maybe we can get MG working on OSX :-)

[macuser]

Hello m0ellemeister,

that sounds great, and I am looking forward to contribute to testing etc. While my experience with Xcode is also limited, I am glad to help in any way.
I have realized that my problem with cmake and the seemingly outdated version of curl could not be resolved, because I had used the macports version for OS X Leopard, while meanwhile running OS X Snow Leopard. There is a .dmg package available on the macports website also for Snow Leopard.
Then "sudo port selfupdate; sudo port upgrade outdated" should help to also update curl, which I cannot test right now (have to leave).

I read that a lot of people have problems with macports after upgrading OS X Leopard to Snow Leopard.
Reportedly, the best way is to completly re-install macports after OS X upgrade.

Sorry to post very OS X- (or rather macports) related stuff here, but it may help to get MG running on OS X, too, hopefully.

PS:
An alternative to macports to get the necessary building tools (i.e. those which are not included with Xcode as far as I understand it) on board is fink.
If there are any further OS X users around, please let us know your hints on how to get MG running, maybe incl. some background info re. Xcode etc., too. Thanks.

The biggest issue here stopping people from helping you is the fact you are on a mac. Macs are the lowest minority here, and are not generally the choice option for a programmer. There was one guy who did have a mac and was trying to keep up to date Mac versions, but I'm not sure if he's still active on the board.

Sorry, but using a mac is going to make this a lot harder. You could try also installing a free Linux operating system alongside that mac for gaming, etc; You may even find linux preferable over the mac (it's a lot different, but also more popular among the tech experienced who aren't hypnotized by the apple logo).

[macuser]

While I appreciate your hint using Linux instead, I would like to express that I am not hypnotized by the Apple logo.
I simply use my Macbook for daily stuff, and it works like a charm. Besides, I also use a virtualized Ubuntu on my Macbbook, which also works nicely for developing and testing stuff (I use it to continuously update my router FW from an svn repository/ project) but virtualization is a little bit too slow for MG or other decent games. Of course it works nicely with dualboot, but booting down OS X and booting up Linux whenever I would like to have a short game session is a little bit annoying. Anyway, I stick to my MB and eventually MG will run on it... or not.

[m0ellemeister]

short Update.

I'm not able to generate a valid Xcode Project file using cmake. But doing it the "unix" way using gnumake for compiling i had come so far:

Code: [Select]

[ 26%] Built target streflop
[ 26%] Building C object source/shared_lib/CMakeFiles/libglest.dir/sources/platform/miniupnpc/miniupnpc.c.o

gnumake[1]: *** [source/shared_lib/CMakeFiles/libglest.dir/all] Error 2
gnumake: *** [all] Error 2

I don't know which dependency is missing.... Maybe someone can point me on it?

Because i'm not able to solve the issue, that cmake won't generate a valid xcode project file, i'll keep my focus on building MG using cmake/gnumake. As soon as i'm able to build MG this way, i'll try to build with Xcode using the Unix style Makefile.

[m0ellemeister]

I could solf this by myself. I had to tweak the miniupnp.c file at the top:

Code: [Select]

#if defined(__APPLE__)
#define _DARWIN_C_SOURCE
#endif

But now i have a new problem:

Code: [Select]

At the moment i'm stuck at this point:

Current directory is: megaglest/data/glest_game

The file which could not be loaded is there:

Code: [Select]

ls -lahrt data/core/menu/textures/line_horizontal.tga
-rw-r--r--  1 user  staff   3,8K  9 Jan 23:36 data/core/menu/textures/line_horizontal.tga

I guess the crash of MG is related to one of used the Libraries, but i'm not sure.

Next steps i could do in this:
- try to compile the whole stuff using Xcode
- reinstall MacOSX (this woun't happen in the near time) and start from scratch (i've the feeling, that i broke some of the Apple Frameworks installed by default)

[softcoder]

run the --verbose on commandline AND turn on the following debugging flags in glestuser.ini:

Code: [Select]

DebugMode=true
DebugNetwork=true
DebugSound=true


[tomreyn]

That's probably not of much use, but it probably doesn't hurt either... People have previously run into this error message about line_horizontal.tga. However, in their case it was because they either did not install the data updates (from 3.3.7.2 to 3.4.0 beta2), unpacked them to the wrong directory (or to a subdirectory of the data directory, creating a data/data/... structure), or unpacked them with incorrect permissions.

[softcoder]

It should look for this file in the same folder as other menu textures (example from the source code in order):

/menu/textures/back.tga
/misc_textures/fire_particle.tga
/misc_textures/snow_particle.tga
/menu/textures/custom_texture.tga
/menu/textures/logo.tga
/misc_textures/water_splash.tga
/menu/textures/button_small.tga
/menu/textures/button_big.tga

/menu/textures/line_horizontal.tga

.. etc. Concerning the root folder, it is configured as:

<some custom path>data/core

where <some custom path> may be directly specified on commandline, for example from mk/build (where I build using the cmake scripts) I run:

../mk/linux/glest.bin --ini-path=../mk/linux/ --data-path=../mk/linux/

if the custom path is not specified it is assumed the data/core/ etc is found in the current folder where you run MG from.

Thanks
