Yes, I do get it built without compile/link warning/errors.
To save some time, please turn off other modules in Ne10
Open $NE10_DIR/CMakeLists.txt and find lines like these:
option(NE10_ENABLE_MATH "Build math functionalities to NE10" OFF)
option(NE10_ENABLE_PHYSICS "Build physics functionalities to NE10" OFF)
option(NE10_ENABLE_DSP "Build dsp functionalities to NE10" ON)
option(NE10_ENABLE_IMGPROC "Build image processing functionalities to NE10" OFF)
Set other modules to OFF and left dsp module on. This is optional, but it will speed up the building.
My steps on Pandaboard Ubuntu 12.04 hard float:
Checkout rfcv3_final_ne10_fft from https://git.linaro.org/people/viswanath.puttagunta/Ne10.git
$ cd $NE10_DIR
$ mkdir build
$ cd build
$ cmake -DGNULINUX_PLATFORM=on -DNE10_LINUX_TARGET_ARCH=armv7 \
Checkout rfcv3_final_opus_fft_ne10 from git://git.linaro.org/people/viswanath.puttagunta/opus.git
$ cd $OPUS_DIR
$ ./configure --host=arm-linux-gnueabihf --enable-intrinsics \
I have also tried
$ ./configure --host=arm-linux-gnueabihf --enable-intrinsics
It works fine to me.
> I will start working on mdct_backward and fixed point fft for ARMv7.
Glad to hear that.
