Celestia Forums

When I project Celestia for educational presentations, it comes out much dimmer and harder to view than other programs, even with a bright projector. This takes a bit of the impact away from an otherwise really great tool. (As a separate topic, it would be nice to have an archive of "really cool edu...

I'd love to see the MySQL interface working...

Hi, OK, I followed pretty much these steps, and it builds fine. Should have checked the libstdc++ settings earlier, as this was left over from the previous build effort (see thread on this topic elsewhere in this forum). I was able to change the path for this just by selecting it under "Targets... c...

I have tried building the cvs version of Celestia under Panther (Mac OS X 10.3) using the latest present version of XCode (the replacement for ProjectBuilder), with the following results. Although the compilation went by with only minor warnings, the linking step produced several undefined symbols: ...

Hi Christophe, Thanks for the reference. Here are a couple of others that may be relevant: SGI's Open Source Software license terms (incl. additions apparently to go with the above): http://oss.sgi.com/projects/GenInfo/NoticeExplan/ OpenGL Sample Implementation code: http://oss.sgi.com/projects/ogl-...

You can't distribute for profit anything that you wrote that includes viral-licensed code, or contrary to the provisions of such licenses; but this should not be a limitation. Of course you can distribute GPL code for profit . How would RedHat and others make a living otherwise? OK, so I should hav...

Chris, You mentioned that there are some licence issues, can you elaborate/paste some links? I'm not a licence specialist, but since Celestia is GPL, I don't think you can legaly link it against a proprietary library. And you would need to do that to get hardware accelerated OpenGL. That being said...

Hi, Just use one of the many csv import filters that exist for the wonderful open source, easy to learn MySQL database and then use the MySQL add-on. Much more powerful and you get everything you want. You can make the csv's from Excel if you wish. (By the way, csv stands for "comma separated variab...

Hm, I think it IS a good idea to keep the celestia prefs in the same place as prefs for other MacOS X applications -- especially given that the XML format is much easier to deal with than random locations and formats for different applications. But I admit that there is room for individual taste her...

Excellent! It's nice to see this confirmed independently. I've gotten further feedback via private messages (the pm icon) that this is working for other people. I don't have write access to cvs. Is someone going to make these updates and get a MacOS X version of 1.3.x (whatever we are up to) release...

Lots, the most important of which are these: 253c257,258 < LIBRARY_SEARCH_PATHS = "/usr/lib/gcc/darwin/3.1 ./Frameworks"; --- > LIBRARY_SEARCH_PATHS = Frameworks; > OPTIMIZATION_CFLAGS = "-O3"; 256a262 > PRECOMPILE_PREFIX_HEADER = YES; 259d264 < USE_GCC3 = YES; This one is trivial -- just thought it...

Hi, No, the libpng essentially has nothing to do with it (either version will work). For other reasons I am just using the straight Developer Tools 2002 version, and have not yet moved to the optional further update that includes support for gcc 3.3 (probably no harm in doing so for this project, bu...

I verified that it does in fact build with the originally packaged version of libpng as distributed from cvs. In the process of studying this, while making sure that none of my usual environmental variables were affecting the build, I found that it had been picking up libpng in fact from my Fink cop...

To be sure of the link order, I eliminated ALL explicit search paths under "Settings .. Simple View ... Search Paths" for all libraries (in the rightmost panel under ProjectBuilder), and added the libpng.dylib and libstdc++ under the left panel under "Linked Frameworks" in addition to the Cocoa and ...

Hi, How are you determining what library should provide the missing symbols? If I try % find /usr/lib -type f | xargs grep 'streambuf' I get Binary file /usr/lib/gcc/darwin/2.95.2/libstdc++.a matches Binary file /usr/lib/gcc/darwin/3.1/libstdc++.a matches Binary file /usr/lib/gcc/darwin/3.1/private/...

Hi, This area contains: % ls -al /usr/lib/gcc/darwin/* total 0 drwxr-xr-x 5 root wheel 170 Jan 1 2003 . drwxr-xr-x 3 root wheel 102 Jan 1 2003 .. drwxr-xr-x 8 root wheel 272 Jan 13 2003 2.95.2 drwxr-xr-x 12 root wheel 408 Jan 13 2003 3.1 lrwxr-xr-x 1 root wheel 3 Jan 1 2003 default -> 3.1 /usr/lib/g...

Hi,

Did so, still same problem.

Do you have access also to the XCode / Developer Tools for that release? Note it will have a newer version of gcc and many libraries will change, so I'm surprised that the existing 1.2.5 app executable from the earlier versions of Mac OS X will work at all -- let's hear it for Mac backward compatibi...

OK, this went fine. Futher similar order-of-declaration problems occurred in SetTimeWindowController.m . Fixed these by moving all declarations of the code block related to dateString, etc. to the beginning of that block. and moving the sim= statement to just after these declarations. (Let me know i...

Also had to do the same for the appCore declaration in FavoritesDrawerController.m Answering my own question above, it looks likely that this is due to the different versions of the Developer Tools (July 2002 for you vs. Dec 2002 for me) that we are using. Based on this and the harmless nature of th...
