[NET] AX.25 Kconfig and docs updates and fixes

[NET] AX.25 Kconfig and docs updates and fixes

[Ralf Baechle]

 o The AX.25 Howto is unmaintained since several years.  I've replaced it
   with a wiki at http://www.linux-ax25.org which provides more uptodate
   information.
 o Change default for AX25_DAMA_SLAVE to Y.  AX25_DAMA_SLAVE only compiles
   in support for DAMA but doesn't activate it.  I hope this gets Linux
   distributions to ship their AX.25 kernels with AX25_DAMA_SLAVE enabled.
   The price for this would be very small.
 o Delete historic changelog from comments, that's what SCM systems are
   meant to do.
 o ---help--- in Kconfig looks so yellingly eye insulting.  Use just help.
 o Rewrite the commented out piece of old Linux 2.4 configuration language
   to Kconfig for consistency.
 o Fixup dependencies.

Error compiling aprsd-2.2.5-15

[Bernard Pidoux]

Hi All,

Is aprsd-2.2.5-15.tar.gz the last available source for aprsd ?

I did ./configure without problem but got g++ warning and the following
error :

deprecated header <iostream.h>. To disable this warning use -Wno-deprecated.
aprsString.h:199: error: extra qualification ‘aprsd::aprsString::’ on
member ‘getMsgText’

I also tried CVS source tree but got stuck as running autoconf to make a
configure file gave error :

configure.ac:8 error: possibly undefined macro: AM_INIT_AUTOMAKE

Can someone help ?

If you're talking SourceForge aprsd, then yes, it appears so.
Others have released aprsd before as well, typically doing so by
adding their callsign into the package name if they did mods.

I'm not a C++ guy so I can't help you there.  If it were me I'd try
looking at the header files and the source code to see where the
mismatch was.

You might need to update your version of "automake" and "autoconf"
on that box.  Or downgrade them.  Note that they work well as a
pair, so sometimes upgrading/downgrading one will require you to do
the same to the other package to make things work smoothly.

Error compiling aprsd-2.2.6-4 from CVS

[Bernard Pidoux]

Hi All,

In aprsd directory captured from CVS sourceforge (aprsd-2.2.6-4)
I changed boostrap.sh file permission to a+x and ran the script.
It built configure script and then I was able to run ./configure and make.

However I got an error during compile :

if g++ -DHAVE_CONFIG_H -I. -I. -I.. -I../src    -g -O2 -Wall
-march=pentium -fPIC -DPIC -pedantic -pipe -pthread -MT aprsd.o -MD -MP

         then mv -f ".deps/aprsd.Tpo" ".deps/aprsd.Po"; else rm -f
".deps/aprsd.Tpo"; exit 1; fi
refcount.hpp:185: error: extra ‘;’
make[2]: *** [aprsd.o] Erreur 1

I removed extra ';' on line 185 of src/refcount.hpp
and also replaced in all concerned files

#include <iostream>
by
#include <sstream>

to remove warnings about deprecated header <iostream>.

Then I ran make and I have still error messages :

If you look at the header files you'll see that things like "cout"
and "cerr" are defined in iostream and don't exist in sstream.

On my system I'm looking in /usr/include/c++/4.0.2/iostream and
SAMEPATH/sstream.

So...  Replacing the include files as you did appears to have
created a new problem.  Change them back and you'll at least be
closer to succeeding.

I looked at configure.log file and found some error report that could be
interesting for aprsd developpers.
I will report here only the errors or warnings lines :

-----------------------

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by aprsd configure 2.2.6-4, which was
generated by GNU Autoconf 2.59.  Invocation command line was

  $ ./configure

Problem is:  Some of these may be standard tests looking for
different flavors of functions to use, so some errors might be
expected.  I find it's best to ignore most of them in that file
except for the particular problems you're trying to solve.  The rest
are wild goose chases.

For instance in Xastir we look for GraphicsMagick first and then
ImageMagick if GM is not found.  Each one of these might check check
multiple locations for the headers and then the libraries, then some
executables.  Failures at any one of these don't mean that we have a
real error or that the package was not found.  It just means the
attempt failed, but a later one may succeed.

What fun huh?

That's a separate warning.

That's probably caused by

   void aprsString::getMsgText(string& msg);

in aprsString.h within the class definition. Remove the 'aprsString::'
prefix from that line and it should work. There are probably others
around the source tree too.

That's how autoconf works - it compiles various test programs to see
what header files and libraries are required to access certain OS
functions. Errors are perfectly normal. You only have a problem if
configure ends in failure.

If you don't want to update the aprsd source, an easy way out is to  
install an older version of g++.  Many linux distributions keep an  
old gcc 3.4.x era g++ (which can be installed alongside the current  
release) around for just such occasions.
