Hello Ken, --enable-64bit doesn't deal with GRASS 64bitness in direct way. What You should had looking for was compiling 32bit apps on 64bit OS. Regarding float overflow - it makes sense. Can You attach a patch to trac ticket? I (or somebody else) will take a look at it and commit to SVN. Thanks for spotting this. Moving conversation to -dev. Maris. 2010/6/16 Ken Kwasnicki ken.kwasni...@gmail.com: Yes, I my slackware can run 32bit apps. I tried recompiling grass without the --enable-64bit option but still had the same nviz problem , although i expect i'm still compiling to 64bit. However, I've looked at the togl_flythrough.c code and found the problem. Or at least found a change the fixes this on my system. I had added some debug output to mouse_valuator just to show the thisTime value, initially I just wanted to see if I would even see the output from a printf statement when running nviz. What I noticed was that the seconds value for thisTime was not incrementing, only the decimal part was changing, which I guess is why the view would return to its original position after a 1 second lapse. in the function this_time the time values are being cast to float which is maxing out so i changed them to double which is the return value anyway. so, i changed this line [320]: return ((float)tv.tv_sec + ((float)tv.tv_usec / 100.0)); to: return ((double)tv.tv_sec + ((double)tv.tv_usec / 100.0)); and that appears to have fixed the problem. the same change may need to be made for the MINGW32 version of the code, but I left that alone. i've made this change in my download of the 6.4.0RC6 version of the code but for now I'll leave it up to you, or others to make this change as I'm currently not set up to submit code. thanks! ken On 06/15/2010 12:53 PM, Maris Nartiss wrote: Hello, at first - You can compile 32bit version on 64bit machine (if it's possible on Slackware). Second - once I took a look at code. It was not good, still I didn't managed to find the root cause. Fly mode is TCL/C hybrid. TCL part is here: http://trac.osgeo.org/grass/browser/grass/branches/develbranch_6/visualization/nviz/scripts (flythrough.tcl) Some support is located in nviz/src/ (togl_flythrough.c) Main rendering is done by OGSF lib/ogsf OGSF should be fine, problem is somewhere in nviz part. Probably in C/TCL interaction. Good luck. If You need some help with coding, feel free to as at grass-dev ML. We are short on resources and thys any help is wecomed. Maris. 2010/6/15, Ken Kwasnicki ken.kwasni...@gmail.com: Hi Maris, Thanks for the reply! Too bad. I guess I'll have to install on a 32bit system. For what it's worth my system is Slackware 13.0 64bit and also Nvidia driver, so nothing really new to add to the bug report other than the variance in linux distribution. Any speculation where this bug might occur in the nviz code? Just in case I'm feeling ambitious enough to take a crack at debugging it.

Has anybody seen this problem before or know what I should do to fix it? Appreciate any assistance.

[GRASS-dev] GRASS startup behaviour on Win differs from Unix
Hi all, when I start GRASS from a Linux shell, going through Init.sh, I can supply the name of a mapset and GRASS will automatically log into that. When I do the same in Windows, from cmd.exe and going through Init.bat, I always get the interactive login screen. Is that intented behaviour? Or is there something I am doing wrong with the mapset path specification? Linux: grass64 $HOME/grassdb/test/usr - logs straight into mapset Win: grass64.bat c:\grassdb\test\user - goes to interactive login Cheers, Ben -- Files attached to this email may be in ISO 26300 format (OASIS Open Document Format).

Re: [GRASS-dev] access to grass (trunk 7.0.svn ) vector map from python
I think there is an error in the generation process with ctypesgen for vector.py. The problem is that dig_estructs.h needs the heading ogr_api.h which is not found in the path included. The problem is solved if you add the path to that file (in my case -I/usr/include/gdal). Thank you. Greetings. Fernando. Ing. Fernando Pacheco M.S.L.

Didn't really follow anything below note 0_sum.c in gr65..., but as for
the commands you suggested:
r.stats a...@permanent - runs fine, no errors, meaningful output
r.stats h...@permanent - runs fine, no errors, meaningful output
g.tempfile pid=1234 - no errors, output is:

That is the correct location mapset. Can't think of anything else to

Re: [GRASS-dev] access to grass (trunk 7.0.svn ) vector map from python
Everything works correctly now, the problem has been fixed. I think the interface generated automatically with ctypesgen (like that of SWIG) isn't attractive for inexperienced developers. It works very well and is fast, but the calls to the functions are complex (logically identical to those of C) and is not what an average developer would expect in Python. In the coming months we will be developing an interface for finite element modeling (Fenics project=Dolfin, Tritetmesh, etc.). We will start by making access to vector layers with Python more friendly, taking as a starting point what has been generated with ctypesgen. Thank you. Greetings. Fernando. Ing.
