Re: [Flightgear-devel] Problems compiling latest CVS snapshot (2005-10-11)
Hi Andy,
thanks for the hint and patch. I should have searched in the mail archive.
With the patch it compiles fine.
Thanks
Matthias
This is a known bug when compiling on a 64 bit system. I fix it in my
tree by double casting:
--- AIBase.cxx 5 Sep 2005 13:25:09 - 1.41
+++ AIBase.cxx 10 Oct 2005 23:39:47 -
@@ -398,7 +398,7 @@
}
int FGAIBase::_getID() const {
-return (int)(this);
+return (int)(long)this;
}
This fix can't be checked in though, because it isn't correct*. The
generated ID is not guaranteed to be unique. The right solution would
be to either change the type of the ID to a long long or uint64_t,
or generate an identifier from something other than the pointer value.

[Flightgear-devel] Problems compiling latest CVS snapshot (2005-10-11)
Hi all,
I tried to compile a new CVS snapshot of FlightGear. I got following error

Does anybody has an idea what this could be?
I am working with SuSE 10.0, Kernel 2.6.13, gcc version 4.0.2 20050901.

Re: [Flightgear-devel] NVIDIA 1.0-7667 breaks shadows entirely.
Oops, you are quite right. I should have thought about it before I had sent this mail.

The man pages of xorg.conf say at DISPLAY SUBSECTION: Depth depth This entry specifies what colour depth the Display subsection is to be used for. This entry is usually specified, but it may be omitted to create a match-all Display subsection or when wishing to match only against the FbBpp parameter. The range of depth values that are allowed depends on the driver. Most driver support 8, 15, 16 and 24. Some also support 1 and/or 4, and some may support other values (like 30). Note: depth means the number of bits in a pixel that are actually used to determine the pixel colour. 32 is not a valid depth value. Most hardware that uses 32 bits per pixel only uses 24 of them to hold the colour information, which means that the colour depth is 24, not 32. Matthias Are you confusing both depth and pixel definition: here an extract from NVIDIA readme DEPTH, BITS PER PIXEL, AND PITCH While not directly a concern when programming modes, the bits used per pixel is an issue when considering the maximum programmable resolution; for this reason, it is worthwhile to address the confusion surrounding the terms depth and bits per pixel. Depth is how many bits of data are stored per pixel. Supported depths are 8, 15, 16, and 24. Most video hardware, however, stores pixel data in sizes of 8, 16, or 32 bits; this is the amount of memory allocated per pixel. When you specify your depth, X selects the bits per pixel (bpp) size in which to store the data. Below is a table of what bpp is used for each possible depth: Depth BPP ------ 8 8 15 16 16 16 24 32 ___ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
[Flightgear-devel] new list member and new aircraft model
Hallo, I'm pretty new to this list. I subscribed to this list several days ago after Mathias Froehlich encouraged me to do so. I'm using and flying with FlightGear for quite a while. So I have started to work on a new aircraft model (Eurocopter EC145). But before I will work further on I want to ask if anybody else is already working on that kind of helicopter? Best regards, Matthias ___ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
