Cross compiling aprx for 32bit from 64bit host
Mon 13 October 2014
I run aprx I-Gate for RF feed to aprs.is to support the local area network.
I develop on a 64 bit version of debian (Testing) but run the node on a 32bit version of stable. Here is my setup and package requirement
On the stable system you need to add the testing repo to the sources list
deb http://ftp.nl.debian.org/debian/ testing main contrib non-free deb-src http://ftp.nl.debian.org/debian/ testing main root@pa2sq:~/workspace/aprs/aprs-pa2sq-5#
apt-get -t testing install libc6-dev
And install glib for the version on testing. This is to allow the cross compiled version to run without updating the host node to testing
On the 64 bit machine you need to supply 32bit compile flag to the autoconf tool
simon@ham$ (git::master) ./configure —build=i586-pc-linux-gnu “CFLAGS=-m32” “CXXFLAGS=-m32” “LDFLAGS=-m32”
then its just a case of copying over the compiled binary to the host
scp aprx root@pa2sq:/usr/sbin/aprx
restart the node and you now have the running version without the need to compile on a machine with low resources.
