Hi all,
I’m trying to build Tom’s branch with the recent changes to use Volk,
but I’m getting an error. I ran this command:
cmake -DCMAKE_INSTALL_PREFIX=/usr
-DCMAKE_TOOLCHAIN_FILE=…/cmake/Toolchains/arm_cortex_a8_native.cmake
-DENABLE_GR_QTGUI=OFF -DCMAKE_BUILD_TYPE=release …/
And got this error:

I feel like the flags from the toolchain file are not getting through to
gcc, try passing the compiler flags via the command line.

That was the next thing I did and now (4 hours later :-P) it appears to
have worked. I’m not sure why it didn’t pick up CMAKE_TOOLCHAIN_FILE.
Thanks,
Sean
Actually, what’s the difference between “-march=armv7-a
-mtune=cortex-a8” and “-mcpu=cortex-a8”?

For some reason it’s not working for me either. I’m always passing the
parameters via command line. Not sure whether it’s a CMake issue. Is it
working for everybody else?

I looked at this the other day and it made me very angry
It is on my list of things to figure out.

It doesn’t work for me, either.

I think the second is a deprecated way to say the first.
