[Pingus-Devel] ClanLib 0.8 (930) on Mac OS X

[Tim Wilson-Brown]

Hi,

I have just installed ClanLib and Pingus from svn:

*Installing ClanLib:

Used the instructions at http://www.clanlib.org/wiki/Compiling
and the dependent libraries listed in the INSTALL.macosx document in  
ClanLib:

I used Xcode 2.3, gcc version 4.0.1 (Apple Computer, Inc. build  
5341), and zlib 1.2.3, all on Mac OS X 10.4.6 (8I127) on a PowerBook G4.


*Getting ClanLib and pingus source:

http://lists.gnu.org/archive/html/pingus-devel/2005-12/msg00060.html
says that ClanLib 0.9 is incompatible with (pingus/Mac OS X)?

So I downloaded ClanLib-0.8 using the instructions at: http:// 
www.clanlib.org/subversion.html
Charis:~/Projects/Pingus twilsonb$ svn co https://clanlib.org/svn/ 
ClanLib/Development/ClanLib-0.8
Error validating server certificate for 'https://clanlib.org:443':

- The certificate hostname does not match.
- The certificate has expired.

(R)eject, accept (t)emporarily or accept (p)ermanently? t

Checked out revision 930.

NOTE: The server certificate is outdated and has the wrong name.


*Building ClanLib 0.8:

I chose to use the universal binary instructions at http:// 
www.clanlib.org/wiki/XCode_Universal_Binaries
and used the binaries from http://www.clanlib.org/download-binaries- 
osx-gcc40-universal.html

I opened the ClanLib.xcode project and upgraded it to an xcodeproj in  
Xcode 2.3.

I downloaded the frameworks and put the in a Frameworks directory,  
then reopened the project.

I changed the project settings to use the universal SDK, and (while I  
was at it) activated Subversion version control. I also needed to  
change the subversion tool path to /sw/bin/svn. I also needed to  
accept the clanlib certificate permanently. I also changed it to  
build for ppc and i386.

I then built using a dedicated build between the two Macs that I have.
(I decided not to wait for Xcode to sort out SCM status).

The build worked fine - about 5-10 minutes - there were some warnings  
about deprecated QuickDraw functions - but nothing that's going to  
cause any problems.

*Running/Debugging:

I get the message:

Pingus: Unknown throw caught!

when a CL_Error is thrown by ClanMikMod - the actual error (retrieved  
by using debugging output before the throw) is:

Compressed sample is invalid for /tmp/build/products/Development/ 
Pingus.app/Contents/Resources/data/music/pingus-1.it

I remember RTTI errors like this having something to do with  gcc,  
and classes in header files. (I do have RTTI and exceptions turned  
on).  Does anyone know where I can find gcc documentation referring  
to this problem? (Or some workarounds?)

I have read it somewhere but I can't find it now when I need it.

Apart from this problem, the game and engine run fine and compile  
well on Mac OS X.  It's good to see game engines that are so portable!
