soundmodem problem with ./configure

soundmodem problem with ./configure

[Bernard Pidoux]

Hi,

An OM from a RadioClub had some warning when doing ./configure
before compiling soundmodem.

I downloaded soundmodem source from

http://www.baycom.org/~tom/ham/soundmodem/soundmodem-0.10.tar.gz

and made the same observation reported here :

checking linux/if.h presence... yes

I have installed all ax25 libs and applications.
I did not have any problems with ./configure scripts before this.

Can someone help ?

For now this is just a warning, it should still compile.  In the long
run someone needs to fix the packages configure script.  The last line
you posted "checking for linux/ax25.h... yes" shows that it is still
acting like it was happy with this file (for now).

The configure script builds a small c program that includes the
file to be tested and sees if there are errors when it is compiled.
Apparently this test program isn't good enough for that file (on your
system).

Look in "config.log".  That will show the test program, the command used
and the results.  

For example I see the same error with "if.h" and see this in config.log:

------------------------------------
configure:7197: checking linux/if.h usability
configure:7209: gcc -c -g -O2  conftest.c >&5

configure:7301: WARNING: linux/if.h: in the future, the compiler will take precedence
configure:7313: checking for linux/if.h
configure:7320: result: yes
------------------------------------

Yet soundmodem compiles just fine (although there are far too many
warnings).

Thank you for providing the above explanations.
Actually, configure fails for it is looking for GTK and it is not
installed on my system.

------------------------------
checking for gtk-config... no
checking for GTK - version >= 1.2.0... no
*** The gtk-config script installed by GTK could not be found
*** If GTK was installed in PREFIX, make sure PREFIX/bin is in
*** your path, or set the GTK_CONFIG environment variable to the
*** full path to gtk-config.
configure: error: Cannot find GTK: Is gtk-config in path?
-------------------------------

Is there any mean to avoid this error ?
Looking at configure script, GTK seems to be optional, but I did not
find how to disable it in configure ?

./configure --disable-gtktest

did not make it.
