Hi Lawrence

I get an error when cross compiling.

I set the path to
instead of
tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin, because I
am using an x64 system. Without that, the compile was failing much
sooner than this.

I get this error, after it completed extracting the source for qt

arm-linux-gnueabihf-g++: not found
-reduce-exports was requested but this compiler does not support it
Re-run configure with -v for more information

it says arm-linux-gnueabihf-g++ not found, but it is found when I use
the path that I set as per the instructions

Proof that arm-linux-gnueabihf-g++ exists:

peter at xubuntu1510x64:~/work/github.com/MythTV/mythtv$

peter at xubuntu1510x64:~/work/github.com/MythTV/mythtv$
arm-linux-gnueabihf-g++: fatal error: no input files
compilation terminated.
