I would like to cross-compile clang for use as a compiler for avr (arduino to be more verbose). I feel like I should be doing something like the following:
- create standalone toolchain from android ndk
- compile with the correct CC and CXX parameters.
Smth yet? Does it support --target = avr or how can I compile? Does it make sense since it will be used as an IDE autocomplete tool for source analysis using the clang-c API?
UPDATE: configuration with the -host and -target options:
export CROSS_COMPILE=arm-linux-androideabi
export CC=${CROSS_COMPILE}-gcc
export CXX=${CROSS_COMPILE}-g++
export NDK=/softdev/android-ndk-r8e
export ANDROID_NDK_ROOT=/softdev/android-ndk-r8e
export SYSROOT=$NDK/platforms/android-8/arch-arm
export PATH=/softdev/arm-toolchain/bin:$PATH:/softdev/android-ndk-r8e/platforms/android-8/arch-arm
./configure --host=arm-linux-androideabi --target=arm-linux-androideabi --prefix=/softdev/arduinodroid_clang/arm
make
... results in an error (Makefile exists):
