Unable to run C++ program in esp32 #3690

Open Sandesh-verma opened 1 month ago

Sandesh-verma commented 1 month ago

I have a hello world program for C++. Then I created a .wasm file for the same using the below command with wasi-sdk.

/opt/wasi-sdk/bin/clang++ -O3  \
        -z stack-size=4096 -Wl,--initial-memory=65536 \
        -o test.wasm main.cpp \
        -Wl,--export=main -Wl,--export=__main_argc_argv \
        -Wl,--export=__data_end -Wl,--export=__heap_base \
        -Wl,--no-entry -Wl,--allow-undefined \
        -fno-exceptions \
        -nostdlib \

I have used build script as reference for creating the wasm and header files (wasm and test_wasm.h are created successfully.)

On trying to execute the generated test.wasm, using WAMR, I get the below errors..

iwasm test.wasm

I am also facing the same error when loading the test_wasm.h file to main.c and trying to build for esp32

please avoid cross-posting. https://github.com/WebAssembly/wasi-sdk/issues/470 it it's really necessary, reference each other.

@yamt I had tried the command you have provided here earlier..Though I am able to run the wasm file generated(from C++) successfully, I am unable to build the esp32 example code after including the generated header from the wasm file in main.c.

probably your module is just too large? have you tried strip, wasm-opt, etc?

Sandesh-verma commented 1 month ago

I have tried using wasm-opt but the size of the produced wasm binary is the same as the original one. 

user@user:~/wamr-code/wasm-micro-runtime/product-mini/app-samples/hello-world$ wasm-opt -Oz -o stripped-test.wasm test.wasm 
user@user:~/wamr-code/wasm-micro-runtime/product-mini/app-samples/hello-world$ du -h
220K    stripped-test.wasm
220K    test.wasm

And I face the same error of seg overflow.

although i don't know what your hello world program is doing, the size of your wasm file seems reasonable for a C++ program. if i were you, i'd try "-no-rtti -flto=full -Wl,-mllvm,-enable-merge-functions" with wasi-sdk 24.0. but i suspect there is no easy way to shrink it much.

Sandesh-verma commented 1 month ago

@yamt i tried with options "-no-rtti -flto=full -Wl,-mllvm,-enable-merge-functions" with wasi-sdk 24.0 -> the file size increases maybe due to wasi-sdk 24.0 , i still get the same error .

$/opt/wasi-sdk/bin/clang++ -O3 -o test.wasm main.cpp -fno-rtti -flto=full -Wl,-mllvm,-enable-merge-functions
$ du -h test.wasm 
1.4M    test.wasm

also interested in knowing if WAMR supports running wasm files generated using emscripten or any other compliers for esp32 , or is the support limited to wasm files produced using wasi-sdk

yamt commented 1 month ago

recent wasi-sdk ships libraries with RelWithDebInfo. you can get a comparable size binary by stripping it.

my usual advice is "don't use C++". :-)

if your esp32 has external flash, maybe you can place your wasm file there.

Sandesh-verma commented 1 month ago

@yamt thanks for the quick response . I will look into stripping of RelWithDebInfo library Any suggestions on-

there is some support for emscripten. but i don't know its state at all. https://github.com/bytecodealliance/wasm-micro-runtime/blob/main/doc/build_wasm_app.md#build-wasm-applications-with-emsdk

zig has wasi target. i dunno c++ works or not though.
