Bugzilla Bug 21096

I spoke to the author of xplanet some time ago about this. I patched my own 
copy, now I'm building my new machine and wished I'd told gentoo.

There is a bug in xplanet when compiled with gcc 3.x. This is as the gcc 
developers chose to change their interpretation of the standard - see http:
//gcc.gnu.org/onlinedocs/libstdc++/faq/index.html#4_4 

The fix is simple, in the words of the author:
> At line 549 in
> libannotate/drawSatellite.cc try putting
> infile.clear();
> just after
> infile.close();

Without this no satellite trails are shown. 

Reproducible: Always
Steps to Reproduce:
0. using gcc 3.x emerge xplanet
1. run xplanet with a valid satellite file : e.g. xplanet -satfile science, 
while under X. 
2. Look for a trail across the map - there won't be one 
3. apply patch and rebuild 
4. repeat 1
5: repeat 2 and see pretty trail of the iss

Actual Results:  
just a map, no satellite trail or image

Expected Results:  
trail and icon of the ISS

I should say that I think all it needs is a tiny patch file. I don't know
enough about patching, but I'm sure there are gentoo developers who do,and can
develop this. There would be no harm in using the patch on gcc 2.9x systems
too, lookign at the code. 

Personally I had the problem that xplanet 0.94-r1 did not make any satellite
information with the following command to the output image: "xplanet -satfile
visible-satellites -output test.jpg". I was in contact with Hari Nair and he
replied saying that he has placed an updated version (0.95a) of the old
xplanet on the xplanet web page. Using this version the satellite images work
perfectly.

Reason why I am staying at 0.9x versions is that Hans Ecke's really handy
scripts (http://hans.ecke.ws/xplanet/) work only with 0.9x versions as at the
moment. He has though mentioned on his web pages that once he has time, he will
make them work with 1.x. :)

i added the patch to 0.94, sorry for the delay

Looks like the patch is not in as of 13th September 2003

now on cvs ... dunno what happened there, my apologies
