I have a RaspberryPi 2 that has the armv7 processor and I'm trying to compile
0.30 version of the qpid/cpp code and having an issue with casting:
[root@raspberrypi2-scanner build]# svn co

...
[root@raspberrypi2-scanner build]# make qpidclient

Previous versions of this error have been fixed with one new '(void*)' per line
with no ill side effects.
