Polymake.jl-0.5 release

Polymake.jl v0.5.0 has been released!

The main and show-stealing reason to bump the major version is the transition of Polymake.jl from BinaryBuilder dependencies to modern Julia artifacts system. Thanks to the transition there is literally no compilation happening during add Polymake and all our libraries should be shining and working with each other.

A huge round of applause is due to @benlorenz, who single-handedly cross-compiled perl for MacOsX on a MIPS router dev-board to make this happen. Without him, nobody would dare to look into the eyes of the beast.

Happy coding,
on the behalf of polymake Team,


The package has been split into Julia-only Polymake.jl and C++ library libpolymake-julia. While this is much easier for the users (and hopefully less error-prone on our side), the development process is somehow more involved (when working on the C++ library). This involves setting your own Overrides.toml in your package depot as well as compiling and linking the library against current versions of libcxxwrap_julia and libjulia. Since these come from artifacts the appropriate paths need to be set while cmakeing. Example work-flow could look as follows

git clone https://github.com/oscar-system/libpolymake-julia
cmake -DJulia_PREFIX=/opt/julia-1.5.1 \ % your julia installation
      -DPolymake_PREFIX=~/.julia/artifacts/eb44608582f284a712e85f226d09d4d2ada2f06c \ % autogenerated artifact
      -DJlCxx_DIR=~/.julia/artifacts/fd5dfb5dee87c41c238d98bd7ff2fdd4f307e824/lib/cmake/JlCxx \ % your cxxwrap_julia artifact
      -DCMAKE_INSTALL_PREFIX=~/local/prefix \ % your installation prefix
      -DCMAKE_BUILD_TYPE=Release \
      -S libpolymake-julia -B build
cmake --build build --config Release --target install -- -j2

Note that the Polymake_PREFIX artifact is generated on the fly and needs to be checked against the ENV["POLYMAKE_DEPS_TREE"] which is populated after using polymake_jll.

Additionally ~/.julia/artifacts/Overrides.toml must contain the following line

libpolymake_julia = "/home/user/local/prefix"

to replace the library loaded by Julia.

For more details please have a look at readme of libpolymake-julia or test-prepare.jl file.
