Link errors on ubuntu 20.04 with clang-10 #47

taichi version

I build taichi from source with latest commit 7cab180f1

* 7cab180f1 2022-10-28 | [Bug] [error] Add argument 'module' to 'warn_explicit' to show the deprecated warning (#6467)

I modified cmake options:

TI_WITH_VULKAN set to ON
TI_WITH_C_API  set to ON

Then I build with:

export CXX=/usr/bin/clang++-10
python3 setup.py install

it success.

taichi-aot-demo version

I build taichi-aot-demo with latest commit 1735a29

* 1735a29 2022-10-25 | Fix VMA usage & debug printing (#45) (HEAD -> master, origin/master, origin/HEAD) [PENGUINLIONG]

export CXX=/usr/bin/clang++-10
export TAICHI_C_API_INSTALL_DIR=/home/zz/work/taichi/_skbuild/linux-x86_64-3.10/cmake-install/c_api

But it failed with:

Also tried a clean build with customized options for taichi-aot-demo:

TI_WITH_VULKAN=OFF
TI_WITH_CPU=ON

but also fails. T_T

zchrissirhcz · 2022-10-28T15:09:42Z

I read the documentation again and find I missed the customized LLVM 10.0 installation.
I'll try it again.

zchrissirhcz · 2022-10-31T01:10:35Z

I installed the customized LLVM-10 from taichi document website, prepend to my PATH env var, and export CC and CXX to clang-10 and clang++-10. With a clean rebuild of taichi and taichi-aot-demo, it still failed to link.

PENGUINLIONG · 2022-10-31T01:44:50Z

If Vulkan is all you need I recommend you to disable llvm compilation with TI_WITH_LLVM=OFF then you don't need LLVM10 anymore

zchrissirhcz · 2022-10-31T02:42:00Z

After disabling TI_WITH_LLVM, it links OK.

The running result of taichi-aot-demo shows that, E1 is OK, E2 and E3 has some error.

Hi @zchrissirhcz,
I pushed a PR just now to fix a similar problem with E3_implicit_fem_headless. Can you pull "master" branch of taichi-aot-demo and try again?

zchrissirhcz · 2022-10-31T02:52:27Z

@jim19930609 Hi, tested but E2 and E3 still has some error message

You should launch the test apps in the root current directory.

jim19930609 · 2022-10-31T03:10:24Z

That looks weird, can you try:

Make a clean build after pulling the master branch
Specify your python executable with: TAICHI_C_API_INSTALL_DIR=... cmake .. -DPYTHON_EXECUTABLE=...

Have you noticed any error message while cmake is running?

zchrissirhcz · 2022-10-31T03:37:35Z

@jim19930609 I pasted the cmake configure full output in the following.

create directory

cd ~/work/taichi-aot-demo
git pull
mkdir build2  # a fresh new build
cd build2

btw we have recently solved a compatibility issue so please ensure you are using the latest master for both repo

jim19930609 · 2022-10-31T03:58:15Z

The cmake outputs looks fine...If you've tried building libtaichi_c_api.so with the latest taichi master and the error still persists, then we have to look into the "vulkan failure" to figure out what's going on with that

I tried exactly the same compilation options and commands locally and was not able to reproduce.

The other thing you can try is goto taichi-aot-demo/mpm88_desktop and setup the linux_compile_and_run.sh - just set BACKEND_NAME to vulkan and TAICHI_REPO to the root dir of taichi. Then execute linux_compile_and_run.sh

BACKEND_NAME="vulkan" # cuda, x64, vulkan
TAICHI_REPO="/home/taichigraphics/workspace/taichi" # example: /home/taichigraphics/workspace/taichi

This example just used a different renderer and the algorithm stays the same

The mpm88_desktop run ok:

jim19930609 · 2022-10-31T05:35:23Z

Great~ I think you can also play with the other ones like implicit_fem, sph, comet (LLVM only), taichi_sparse(LLVM only) - they all used the old renderer.

Meanwhile, I'm also concerned about the vulkan failure with the new renderer. Was wondering if you may help with printing out the Error Code upon failure? Just goto taichi-aot-demo/framework/src/taichi/aot_demo/renderer.cpp and insert:

inline void check_vulkan_result(VkResult result) {
  if (result < VK_SUCCESS) {
    std::cout << static_cast<int>(result) << std::endl;
    throw std::runtime_error("vulkan failed");
  }
}

(I admit our error msg needs has way more to improve...)

Thanks!

oh @zchrissirhcz try running ./build3/glfw/E2_mpm88_glfw in this case? (which will give you a lot of validation errors IIUC

@zchrissirhcz sorry for suggesting this, but https://www.reddit.com/r/vulkan/comments/p8krz8/vk_layer_khronos_validation_layer_not_present/ says rebooting the computer solved the problem for him/her :P

FYI in case this still doesn't work, we'll try to find a combo of RTX2080+ ubuntu20.04 +vulkan sdk 1.3 on our side to repro, but that may take longer so we'd like to bisect this down as far as possible. Thanks a lot!

zchrissirhcz · 2022-10-31T07:25:46Z

OK, rebooted my machine, and re-run. Still get same error message.
