Re: [Gmat-developers] GMAT fails to compile on Debian GNU/Linux amd64

[Darrel J. C. <gm...@th...>]

Hi, folks.  Liam Healy sent out a useful listing showing some warnings 
and errors that show up when compiling GMAT on Linux built for AMD 64 
bit processors.  I'm sending a pared down version of this message to the 
mailing list because SourceForge had trouble with the size of the 
original message (it looks like there is a 40k message size limit). 

(Liam: please reply if I missed anything in my butchering of your message!)

There are 2 issues that this dump points out.  I knew about the first 
one, which generates the errors that stop the build, is related to 
unicode versions of the wx libraries.  I'm currently in the process of 
correcting that issue.  The second appears on the 64 bit build because 
of our usage of the string::npos parameter in comparisons; these 
comparisons are generating warning messages in the form "warning: 
comparison is always true due to limited range of data type" when 
building GMAT on 64 bit Linux.  At least, that's my current working theory.

I'll finish fixing the unicode issues first, since they affect anyone 
using prebuilt wx libraries on both Debian and Red Hat, and then look 
for a clean way to address the npos issues.

See my blog http://lhealy.livejournal.com/7623.html?thread=14535
Compiling for Debian GNU/Linux etch amd64.
I am compiling with wxwindows 2.6 since 2.8 is not yet in Debian.

Set
  WX_28_SYNTAX = 0
Also link
  ln -sf topLevelBuildFiles/linux/MakeGmat.eclipse
topLevelBuildFiles/linux/BuildEnv.mk .
Need to redefine to remove local from path:
  WXCPPFLAGS = `/usr/bin/wx-config --cppflags`
  WXLINKFLAGS = `/usr/bin/wx-config --libs --gl-libs --static=no`

then it fails to build:
