compiler-rt build failed
ranciere opened this issue · comments
Hi,
The compilation of clang, binutils is successful, but during compilation of compiler-rt it fails. The cmake config:
cmake .. -DBUILD_PLATFORM_RPI=ON -DBUILD_PLATFORM_SYSROOT=OFF -DBUILD_MRAA=ON -DTARGET_HOSTNAME=pi@192.168.100.161 -DSDK_ROOT_DIR=/home/rancier/rpi
The invoked command and the error message:

Hi again,
If I comment out the exclude line, then compilation of the compiler-rt is successful. Is it okay?
BUT: The next problem is coming: the libunwind. Messages:

Any idea?
Hi @ranciere
What triple and cpu are you targeting?
Hi @jwinarske
CPU: Broadcom BCM2711, Quad core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz (from: https://www.raspberrypi.org/products/raspberry-pi-4-model-b/specifications/)
Triple: arm-linux-gnueabihf
Could be this a 32 vs 64 bit problem?
Hi @ranciere
I've been working on a major update that handles the llvm github migration and some external C-Libs, but I think for your case you just need this:
git clone https://github.com/llvm/llvm-project
cd llvm-project
git checkout llvmorg-10.0.0
mkdir build && cd build
cmake ../llvm -DLLVM_ENABLE_PROJECTS="clang;lld;libunwind;compiler-rt;libcxx;libcxxabi" -DLLVM_TARGETS_TO_BUILD="ARM;AArch64" -DLLVM_DEFAULT_TARGET_TRIPLE=arm-linux-gnueabihf -DLLVM_ENABLE_PER_TARGET_RUNTIME_DIR=ON -DLLVM_BUILD_RUNTIME=ON
If you're not building for aarch64, then don't build that target.
Hi @jwinarske,
Thank you, I will give a try at the evening (in local time, so it's night in your time zone). I will definitely notify you.
Hi @jwinarske
BTW the purpose of the compiler is the same as yours: I would like to build a flutter engine for Raspberry Pi.
In the case of the Flutter Engine, I just checked in changes into flutter_embedded master last night that should unblock you. I moved to using the built-in Fuchsia Clang 11.0. There is no longer an external Clang dependency. After running cmake, run make engine. It's building tip of the tree as of yesterday.
Great! I will try it asap! :)
I've tried the vanilla clang build: the build was successful, but my virtual machine broke before I could try it. So reinstall and retry.
Yeah I built it as well. It generates the arm-linux-gnueabihf runtime libs, only when you dump them with readelf, it matches the host machine. I would stick with flutter_embedded until I sort out my changes.
Hi @jwinarske,
Okay!
