Installation error

[jfuentess]

Hi all,

Thanks for the project! It is really nice for people working on compact data structures-

I'm trying to use it for an academic project, but I have problems with the installation process. What I did is this:

git clone https://github.com/QratorLabs/pysdsl.git . (Get the lastest version of pysdsl)
pip install pybind11 (install pybind11)
cd pysdsl/sdsl-lite; sudo bash install.sh /usr/local/ (install SDSL)
cd ..; python3 setup.py build

but after reaching this point, the compilation process gets stuck. After 4 hours, I obtain this error

`... pysdsl/init.cpp:43:56: required from here
pysdsl/calc.hpp:41:30: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
pysdsl/init.cpp: In function ‘void pybind11_init_pysdsl(pybind11::module_&)’:

Any idea what the problem is?

Some extra información:

• The version of x86_64-linux-gnu-gcc is 7.5.0
• The version of pip is 21.3.1

Hi again,

I've been testing different versions of PIP and pybind11, but without success ()).

In summary, I tried combinations of the following versions:

• PIP versions 22.3.1 and 9.0.3. When using version 22, the installation path of pybind11 seems to be lost. It seems to be a problem of PIP. Following the recommendations here I tried with version 9.0.3 of PIP and, at least, the problem with the path was solved.
• pybind11 versions 2.10.1, 2.2.0 and 2.3.dev0. The version 2.10.1 is the version installed running 'pip install pybind11' in my system. The version 2.2.0 is the minimum required for PySDSL, and version 2.3.dev0 is the one in the repository of PySDSL
• Python version 3.9.2

Across all combinations, I obtained 3 kinds of errors:

• Infinite loop error (combinations pip 22.3.1 and pybind11 2.10.1; pip 9.0.3 and pybind11 2.3.dev0; pip 9.0.3 and pybind11 2.10.1)

• Not path found for pybind11 (combinations pip 22.3.1 and pybind11 2.2.0; pip 22.3.1 and pybind11 2.3.dev0)

Any ideas?

Thanks in advance!
