[TuxKart-users] I have a compilation problem(corection)

[al <al...@te...>]

Mandrake 7.1
Glide_V3-2.60.15-3mdk.rpm & devel rpm
Mesa3.2(compiled from source)
plib-1.2.0-i586.rpm (NOT source)

Q3Ademo, UTdemo, TerminusDemo, several other 3d apps run fine
but......
when I tried to compile tuxkart...

./configure runs without a hitch
make gives this:

SHORT ANSWER:

  Well, I'm guessing that the short answer is to hack in:

      #include <float.h>

  ...into PLIB's src/sg.h, to re-build and re-install PLIB, and then
  to try again...but that doesn't compile on my Linux box.

LONG ANSWER:

  OK - I'm officially confused.

  1)  I always used to use 'math.h' which defined FLT_MAX.
      /usr/include/math.h *uses* FLT_MAX - so that ought to be OK.

  2)  That stopped working in a recent release - because it's
      actually defined in 'float.h' which has ceased to exist
      (at least under SuSE Linux 6.4).

  3)  At the top of 'values.h' it says:

      /*
        This interface is obsolete.  New programs should use
        <limits.h> and/or <float.h> instead of <values.h>. */

      ...but float.h has 'gone away' and 'limits.h' doesn't
      define it either.

  4)  At the end of 'limits.h', it says this:

      #if defined __GNUC__ && !defined _GCC_LIMITS_H_
      /* `_GCC_LIMITS_H_' is what GCC's file defines.  */
      # include_next <limits.h>
      #endif
 
      What the heck is '#include_next' ??!?

Aaaarrrggghhhhh!!!!

Anyway, somehow (despite FLT_MAX not being defined in ANY header file
I can find), my code compiles without <float.h>  ... I suspect that
these tokens are perhaps hard-coded into the C/C++ compiler so that
cross-compilation can work or something like that.

Does *anyone* have a clue?

this doesn't work for me either
plib doesn't compile with or without the sg.h edit, I installed a
bin rpm

this sounds like it makes sense
but since I am not a programmer
that dont mean much :)

OK - since you are a non-programmer, let's try to do a kludge to
get you up and running while we all go off and try to figure out
WTF is going on here.

To get you up and running, (and assuming you can install PLIB
from the RPM) edit /usr/include/plib/sg.h and add this just
before it says '#define sgFloat float' :

    #ifndef FLT_MAX
    #  define FLT_MAX (3.40282e+38)
    #endif
    #ifndef DBL_MAX
    #  define DBL_MAX (1.79769e+308)                                          
    #endif

Boy - those are *BIG* numbers! ...anyway, that should allow you
to compile and run TuxKart OK.

Sorry for the hassle - I have no idea why this doesn't work for you.

Certainly, it is no hassel, anything worthwhile always takes some
work

I made that change:

/usr/include/plib/sg.h
-------<snip>--------
#ifdef __CYGWIN__
#include <float.h>
#endif

#ifndef FLT_MAX
#  define FLT_MAX (3.40282e+38)
#endif
#ifndef DBL_MAX
#  define DBL_MAX
(1.79769e+308)                                          
#endif

#define sgFloat float
#define SGfloat float
-------<snip>---------
after editing sg.h...
cd tuxkart/
make clean
rm config.cache
./configure (no errors)
make     
which gives:

OK - then there is *certainly* something broken about your machine setup.

atan2 is defined in /usr/include/math.h which tuxkart includes unconditionally.

All I can suggest is that you re-install your Mandrake C/C++ development
package.

good deal
I will try that

I think you are right bcause I cant compile some other stuff either

a small Q
are we talking about libstdc++
or libstdc++-devel
or both?

or somthing else

I'm not sure how Mandrake packages things - but 'math.h' should be
in the standard C compiler package - not specifically in C++.

Is there a 'libstdc' and 'libstdc-devel' ?   If so, I'd guess that
libstdc-devel was the missing one - but like I said - I don't know
the mandrake distro at all well.  It certainly wouldn't hurt to
re-install libstdc++-devel too.

would we be talking about glibc here?

Well, no idea about the FLT_MAX problem, but I can say you were for
include_next are:

$ info cpp index \#include_next
