Installation on Linux systems other than Ubuntu

[snowlover173]

Hi How can I install it on Linux systems other than Ubuntu? It doesn't work.

[ameliabennett]

I have it working on RHEL... What does your bug look like?

@snowlover173 does pip install corels not work?

[snowlover173]

It fails with cannot build the wheel with a lot of errors such as: corels/src/corels/rule.h:28:17: fatal error: gmp.h: No such file or directory.

@snowlover173 seems that your problem is not having GMP installed. Install GMP through your linux distro's package manager and try installing pycorels again.

[snowlover173]

it has gmp. I think the issue is gcc. I will try working on that to see what happens.

@snowlover173 I think you're using an older version of g++, which isn't supporting c++11. Try upgrading both gcc and g++ to the newest version (version 9, or 8 should work fine as well).

[snowlover173]

For the record I ran: yum install gcc72-c++

And ran: pip install corels and it worked.

[fingoldin]

Awesome! Glad it worked :D

Can I suggest one modification and/or alternate? I actually like to rely on my system Python libraries and my box already had setuptools, numpy and pytest. But when I attempt to use pip or pip3 it ends up re-downloading wheels for packages I already have.

Solution: python3 setup.py install

Maybe you could mention along with the line for pip (which these on newer Ubuntu is probably meant to be pip3).

Anyway, thanks for setting this up. It installs fine, and the examples run fine too. Ubuntu 19.10.

PS It may also help to mention git clone --recurse-submodules git@github.com:fingoldin/pycorels.git right at the top or else the corels/src/corels/ directory may end up empty.
