Hello ClanLib developers! Our internal checks, here at SUSE, found out that ClanLib source code is missing <cstring> in #includes. I'm attaching a patch (includes.patch) :) Also I noticed that ClanLib uses CLvoid instead of void. In GCC 4.3+ types typedefed to void cannot be used in places where void is expected. (For example, you cannot pass CLvoid* to function expecting void*). Please keep that in mind, when GCC 4.3 is out and being used. -- Best Regards / S pozdravom, Pavol RUSNAK SUSE LINUX, s.r.o Package Maintainer Lihovarska 1060/12 PGP 0xA6917144 19000 Praha 9, CR prusnak[at]suse.cz http://www.suse.cz |

That's a very common warning in MSVC that is often just gotten rid of in cross-platform code with a #pragma disable.. 4244, maybe? I think other parts of ClanLib might have that pragma setting?

Hi Ben, Sorry for the slow reply and thanks for the patch. Anyway, I applied it, but figured I'd better not commit right away = because I noticed I was still getting compiler warnings for many things that were changed, for instance: The old float offx1 =3D cos(M_PI * 2.0 * (e / numsegments))*radius; And the new float offx1(cos(M_PI * 2.0 * (e / numsegments))*radius); give the same warning under VS8: .\Display\Collision\collision_outline.cpp(333) : warning C4244: 'initializing' : conversion from 'double' to 'float', possible loss of = data I can fix it by doing this: float offx1 =3D (float)cos(M_PI * 2.0 * (e / numsegments))*radius; so I wanted to ask, what compiler(s) are you using on your side? GCC = 4.X? Is it possible for you to also test under MS VS8? Probably not but hey, thought I'd ask :) =20 -Seth =20 -----Original Message----- From: Ben Chambers [mailto:bdc...@ya...]=20 Sent: Thursday, December 21, 2006 5:31 AM To: ClanLib Devel Subject: [Clanlib-devel] Patch for warnings Since warnings bug me, I've patched a number of files to get rid of = them.

This patch implements a PRNG for ClanLib. Multiple independent and unique RN streams may be created by instancing the class. Personally, I use this feature for procedural content generation, where you want the random placement to remain static across multiple executions despite other uses of the PRNG. I feel that this is an essential component for a game engine, which unfortunately few people pay attention to, but which would benefit ClanLib and its users immensely. Class use is simple: CL_Random r( SEED ); will instantiate the class, using a 32bit integer seed (it is possible to implement this with 64bit integers, but I didn't bother). unsigned int x=r.rand(); will assign a random value to x in the range of 0x0 .. 0xffffffff (any 32bit unsigned integer value). In addition to this, however, it has several other functions which are useful for random generation: even() returns either true or false, with a good distribution between the two. normalized() returns a float in the range of 0..1 inclusive, with an even distribution. ranged(min, max) returns a float in the range of min..max with an even distribution. distributed(mean, deviation) is special :) It returns potentially any float value. Approximately 50% of all the values return lie within 1 deviation from the mean (note: This is NOT a Standard Deviation, and the resulting curve is NOT a normal bell curve!). Approximately 75% of all values lie within 2 deviations from the mean. If you want to know what percentage P of all values will lie within X deviations from the mean, it is: P = 1-1/(2^x) I don't know a better way to explain this; if someone comes up with one, I'd appreciate hearing how they put it! And that's just about it :) The code is not yet thread-safe; if you will be accessing the same instance from multiple threads, it needs to be wrapped in a mutex. However, independent instances may be used in independent threads quite safely. ...Chambers |

Since warnings bug me, I've patched a number of files to get rid of them. Mostly, I've included explicit type castes where the casting was done implicitly. Also, in collision_outline.cpp, on lines 300, 339, 366, I changed truncate-by-caste (requires two castes) to floor(). Note that, in collision_outline.cpp, on lines 456, 457, 519, 520, 588, 589: Changing what's included in the parenthesis could affect rounding. ...Chambers __________________________________________________ Do You Yahoo!?
