Open rafalf opened 3 years ago

rafalf commented 3 years ago

I am seeing the following exception on my Mac while performing local POW

exception: dlopen(/Users/rafalfusik/gitprojects/iotaPerfm/venv/lib/python3.7/site-packages/pow/libccurl.so, 6): no suitable image found.  Did find:

what I have installed

hey @rafalf , yeah, the pip version is for linux. If you want to use it on Mac, you have to recompile the c library libccurl.so. You can do so by following this: https://github.com/iotaledger/ccurl.interface.py#installation

lzpap commented 3 years ago

@rafalf essentially you need to clone the repo, run init.sh and then pip install -e .

I ran the init and then installed but then I found out that the image is not getting built 

(venv) Rafals-MacBook-Air:ccurl.interface.py ABC$ cd ccurl_repo/ccurl && mkdir -p build && cd build && cmake .. && cmake --build .
CMake Deprecation Warning at deps/libopencl-stub/CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 2.8.12 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.

cd ../../..
 $(find ./ccurl_repo -name "*.so")

and I get no hits, .so aint getting built

lzpap commented 3 years ago

@rafalf is it possible that on mac, cmake builds a .dylib instead of a .so?

rafalf commented 3 years ago

@lzpap Yup 

(venv) Rafals-MacBook-Air:ccurl.interface.py ABC$ find ./ccurl_repo -name "*.dylib"
./ccurl_repo/ccurl/build/lib/libccurl.dylib
lzpap commented 3 years ago

@rafalf just out of curiosity, what happens, when you rename the created file to .so? Does it work? If not, then quite some things should be changed in the repo, it was developed with mainly linux and windows in mind...

rafalf commented 3 years ago

Copied a few bits and pieces from the init 

mv ./ccurl_repo/ccurl/build/lib/libccurl.dylib ./ccurl_repo/ccurl/build/lib/libccurl.so
LIB=$(find ./ccurl_repo -name "*.so")
WD=$(pwd)
cp $LIB $WD/pow
pip install -e .

Working like a charme @lzpap . thanks mate!
