I was able to cross-compile linphone, but it was rather an involved process.

I ended up removing the use of libtool because I could not get the final
'make install' step to work with libtool in a cross-compilation
environment.  I made some other changes to configure.in and possibly
Makefile.am.  I believe the changes I made have been fed back to Simon
Morlat as part of a snapshot sent by my coworker Leonidas.

I did not build the qt linphone, but did build a GTK-only interface that
Leonidas wrote.

The following steps are pretty generic instructions for how to
cross-compile an application.

First, you need to add to the cross-compiler all the libraries and
header you will need to build the application.  For linphone gtk, this
is quite a long list, including gtk, gdk, pango, ...   I gave up on
installing individual libraries and copied over all the files from the
devcluster machine ipaq3.handhelds.org.

The toolchain I used was installed in /usr/local/arm/3.2.3/ so the ARM
headers were copied to /usr/local/arm/3.2.3/arm-linux/include and the
ARM libraries were copied to /usr/local/arm/3.2.3/arm-linux/lib

Make sure /usr/local/arm/3.2.3/bin is on your PATH.

Next: configure the package:

  export PKG_CONFIG=arm-linux-package-config
  ./configure --host=arm-linux

arm-linux-package-config is a short script I wrote so that packages that
configure using pkg-config will use the headers/libraries in
/usr/local/arm/3.2.3 instead of /usr:

  #!/bin/sh

  export PREFIX=/usr/local/arm/3.2.3/arm-linux
  result=`pkg-config $* | sed 's|/usr|/usr/local/arm/3.2.3/arm-linux|g'`
  echo $result

It is still a bit of a hack because it uses the build machine's .pc
files for pkg-config instead of .pc files installed under
/usr/local/arm/3.2.3/arm-linux/lib -- but I could not find an option to
cause pkg-config to look at different .pc files.

At this point: make all should invoke the arm-linux toolchain instead of
the build machine's toolchain.


Hope this helps.
