error while loading shared libraries: libraven.so:

[gunjanpandey]

Could you please help with the following error while starting

raven: error while loading shared libraries: libraven.so: cannot open shared object file: No such file or directory

[rvaser]

Hi, raven does not build any shared library, are you at the right repository? I am aware there exists a package called raven in conda-forge, while this repo is packaged as raven-assembler in bioconda. Might this be the problem?

Best regards, Robert

I don't know if I ran into the same error, but it seems similar.

I cloned the repo and attempted to install with the instructions listed in the readme.

$ git clone https://github.com/lbcb-sci/raven && cd raven

I also tried installing with ninja and found the same error. Is this a Doxygen or Boost error?

As a follow up, this is what gets installed in build and build/lib (build/lib is empty)

$ ls build

For anyone else that runs into this issue, it appears that there's a step missing in the readme. It should actually be

cmake -S ./ -B ./build -DRAVEN_BUILD_EXE=1 -DCMAKE_BUILD_TYPE=Release -Wno-dev && \
    cmake --build build && \
    cmake --install ./build
